  • jQuery Validation hiding or tearing down jquery Modal Dialog on submit

    - by Programmin Tool
    Basically when clicking the modal created submit button, and calling jQuery('#FormName').submit(), it will run the validation and then call the method assigned in the submitHandler. After that it is either creating a new modal div or hiding the form, and I don't get why. I have debugged it and noticed that after the method call in the submitHandler, the form .is(':hidden') = true and this is true for the modal div also. I'm positive I've done this before but can't seem to figure out what I've done wrong this time. The odd this is a modal div is showing up on the screen, but it's completely devoid of content. (Even after putting in random text outside of the form. It's like it's a whole new modal div) Here are the set up methods: function setUpdateTaskDiv() { jQuery("#UpdateTaskForm").validate({ errorLabelContainer: "#ErrorDiv", wrapper: "div", rules: { TaskSubject: { required: true } }, messages: { TaskSubject: { required: 'Subject is required.' } }, onfocusout: false, onkeyup: false, submitHandler: function(label) { updateTaskSubject(null); } } ); jQuery('#UpdateDiv').dialog({ autoOpen: false, bgiframe: true, height: 400, width: 500, modal: true, beforeclose: function() { }, buttons: { Submit: function() { jQuery('#UpdateTaskForm').submit(); }, Cancel: function() { ... } } }); where: function updateTaskSubject(task) { //does nothing, it's just a shell right now } Doesn't really do anything right now. Here's the html: <div id="UpdateDiv"> <div id="ErrorDiv"> </div> <form method="post" id="UpdateTaskForm" action="Calendar.html"> <div> <div class="floatLeft"> Date: </div> <div class="floatLeft"> </div> <div class="clear"> </div> </div> <div> <div class="floatLeft"> Start Time: </div> <div class="floatLeft"> <select id="TaskStartDate" name="TaskStartDate"> </select> </div> <div class="clear"> </div> </div> <div> <div class="floatLeft"> End Time: </div> <div class="floatLeft"> <select id="TaskEndDate" name="TaskEndDate"> </select> </div> <div class="clear"> </div> </div> <div> <div class="floatLeft"> Subject: </div> <div class="floatLeft"> <textarea id="TaskSubject" name="TaskSubject" cols="30" rows="10"></textarea> </div> <div class="clear"> </div> </div> <div> <input type="hidden" id="TaskId" value="" /> </div> <div class="clear"></div> </form> </div> Odd Discovery Turns out that the examples that I got this to work all had the focus being put back on the modal itself. For example, using the validator to add messages to the error div. (Success or not) Without doing this, the modal dialog apparently thinks that it's done with what it needs to do and just hides everything. Not sure exactly why, but to stop this behavior some kind of focus has to be assigned to something within the div itself.

  • Looking into the jQuery LazyLoad Plugin

    - by nikolaosk
    I have been using JQuery for a couple of years now and it has helped me to solve many problems on the client side of web development.  You can find all my posts about JQuery in this link. In this post I will be providing you with a hands-on example on the JQuery LazyLoad Plugin.If you want you can have a look at this post, where I describe the JQuery Cycle Plugin.You can find another post of mine talking about the JQuery Carousel Lite Plugin here. Another post of mine regarding the JQuery Image Zoom Plugin can be found here. You can have a look at the JQuery Overlays Plugin here . There are times when when I am asked to create a very long page with lots of images.My first thought is to enable paging on the proposed page. Imagine that we have 60 images on a page. There are performance concerns when we have so many images on a page. Paging can solve that problem if I am allowed to place only 5 images on a page.Sometimes the customer does not like the idea of the paging.Believe it or not some people find the idea of paging not attractive at all.In that case I need a way to only load the initial set of images and as the user scrolls down the page to load the rest.So as someone scrolls down new requests are made to the server and more images are fetched. I can accomplish that with the jQuery LazyLoad Plugin.This is just a plugin that delays loading of images in long web pages.The images that are outside of the viewport (visible part of web page) won't be loaded before the user scrolls to them. Using jQuery LazyLoad Plugin on long web pages containing many large images makes the page load faster. In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like. You can use Visual Studio 2012 Express edition. You can download it here.  You can download this plugin from this link. I launch Expression Web 4.0 and then I type the following HTML markup (I am using HTML 5)<!DOCTYPE html><html lang="en">  <head>    <title>Liverpool Legends</title>    <script type="text/javascript" src="jquery-1.8.3.min.js"></script>        <script type="text/javascript" src="jquery.lazyload.min.js" ></script></head>  <body>    <header>                <h1>Liverpool Legends</h1>    </header>        <div id="main">             <img src="barnes.JPG" width="800" height="1100" /><p />        <img src="dalglish.JPG" width="800" height="1100" /><p />                <img class="LiverpoolImage" src="loader.gif" data-original="fans.JPG" width="1200" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="lfc.JPG" width="1000" height="700" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="Liverpool-players.JPG" width="1100" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="steven_gerrard.JPG" width="1110" height="1000" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="robbie.JPG" width="1200" height="1000" /><p />          </div>            <footer>        <p>All Rights Reserved</p>      </footer>                    <script type="text/javascript">                $(function () {                    $("img.LiverpoolImage").lazyload();                });        </script>     </body>  </html> This is a very simple markup. I have  added references to the JQuery library (current version is 1.8.3) and the JQuery LazyLoad Plugin. Firstly, I add two images         <img src="barnes.JPG" width="800" height="1100" /><p />        <img src="dalglish.JPG" width="800" height="1100" /><p />  that will load immediately as soon as the page loads. Then I add the images that will not load unless they become active in the viewport. I have all my img tags pointing the src attribute towards a placeholder image. I’m using a blank 1×1 px grey image,loader.gif.The five images that will load as the user scrolls down the page follow.         <img class="LiverpoolImage" src="loader.gif" data-original="fans.JPG" width="1200" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="lfc.JPG" width="1000" height="700" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="Liverpool-players.JPG" width="1100" height="900" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="steven_gerrard.JPG" width="1110" height="1000" /><p />        <img class="LiverpoolImage" src="loader.gif" data-original="robbie.JPG" width="1200" height="1000" /><p /> Then we need to rename the image src to point towards the proper image placeholder. The full image URL goes into the data-original attribute.The Javascript code that makes it all happen follows. We need to make a call to the JQuery LazyLoad Plugin. We add the script just before we close the body element.         <script type="text/javascript">                $(function () {                    $("img.LiverpoolImage").lazyload();                });        </script>We can change the code above to incorporate some effects.          <script type="text/javascript">  $("img.LiverpoolImage").lazyload({    effect: "fadeIn"  });    </script> That is all I need to write to achieve lazy loading. It it true that you can do so much with less!!I view my simple page in Internet Explorer 10 and it works as expected. I have tested this simple solution in all major browsers and it works fine. You can test it yourself and see the results in your favorite browser. Hope it helps!!!

  • How to use jQuery Date Range Picker plugin in asp.net

    - by alaa9jo
    I stepped by this page: http://www.filamentgroup.com/lab/date_range_picker_using_jquery_ui_16_and_jquery_ui_css_framework/ and let me tell you,this is one of the best and coolest daterangepicker in the web in my opinion,they did a great job with extending the original jQuery UI DatePicker.Of course I made enhancements to the original plugin (fixed few bugs) and added a new option (Clear) to clear the textbox. In this article I well use that updated plugin and show you how to use it in asp.net..you will definitely like it. So,What do I need? 1- jQuery library : you can use 1.3.2 or 1.4.2 which is the latest version so far,in my article I will use the latest version. 2- jQuery UI library (1.8): As I mentioned earlier,daterangepicker plugin is based on the original jQuery UI DatePicker so that library should be included into your page. 3- jQuery DateRangePicker plugin : you can go to the author page or use the modified one (it's included in the attachment),in this article I will use the modified one. 4- Visual Studio 2005 or later : very funny :D,in my article I will use VS 2008. Note: in the attachment,I included all CSS and JS files so don't worry. How to use it? First thing,you will have to include all of the CSS and JS files into your page like this: <script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script> <script src="Scripts/jquery-ui-1.8.custom.min.js" type="text/javascript"></script> <script src="Scripts/daterangepicker.jQuery.js" type="text/javascript"></script> <link href="CSS/redmond/jquery-ui-1.8.custom.css" rel="stylesheet" type="text/css" /> <link href="CSS/ui.daterangepicker.css" rel="stylesheet" type="text/css" /> <style type="text/css"> .ui-daterangepicker { font-size: 10px; } </style> Then add this html: <asp:TextBox ID="TextBox1" runat="server" Font-Size="10px"></asp:TextBox><asp:Button ID="SubmitButton" runat="server" Text="Submit" OnClick="SubmitButton_Click" /> <span>First Date:</span><asp:Label ID="FirstDate" runat="server"></asp:Label> <span>Second Date:</span><asp:Label ID="SecondDate" runat="server"></asp:Label> As you can see,it includes TextBox1 which we are going to attach the daterangepicker to it,2 labels to show you later on by code on how to read the date from the textbox and set it to the labels Now we have to attach the daterangepicker to the textbox by using jQuery (Note:visit the author's website for more info on daterangerpicker's options and how to use them): <script type="text/javascript"> $(function() { $("#<%= TextBox1.ClientID %>").attr("readonly", "readonly"); $("#<%= TextBox1.ClientID %>").attr("unselectable", "on"); $("#<%= TextBox1.ClientID %>").daterangepicker({ presetRanges: [], arrows: true, dateFormat: 'd M, yy', clearValue: '', datepickerOptions: { changeMonth: true, changeYear: true} }); }); </script> Finally,add this C# code: protected void SubmitButton_Click(object sender, EventArgs e) { if (TextBox1.Text.Trim().Length == 0) { return; } string selectedDate = TextBox1.Text; if (selectedDate.Contains("-")) { DateTime startDate; DateTime endDate; string[] splittedDates = selectedDate.Split("-".ToCharArray(), StringSplitOptions.RemoveEmptyEntries); if (splittedDates.Count() == 2 && DateTime.TryParse(splittedDates[0], out startDate) && DateTime.TryParse(splittedDates[1], out endDate)) { FirstDate.Text = startDate.ToShortDateString(); SecondDate.Text = endDate.ToShortDateString(); } else { //maybe the client has modified/altered the input i.e. hacking tools } } else { DateTime selectedDateObj; if (DateTime.TryParse(selectedDate, out selectedDateObj)) { FirstDate.Text = selectedDateObj.ToShortDateString(); SecondDate.Text = string.Empty; } else { //maybe the client has modified/altered the input i.e. hacking tools } } } This is the way on how to read from the textbox,That's it!. FAQ: 1-Why did you add this code?: <style type="text/css"> .ui-daterangepicker { font-size: 10px; } </style> A:For two reasons: 1)To show the Daterangepicker in a smaller size because it's original size is huge 2)To show you how to control the size of it. 2- Can I change the theme? A: yes you can,you will notice that I'm using Redmond theme which you will find it in jQuery UI website,visit their website and download a different theme,you may also have to make modifications to the css of daterangepicker,it's all yours. 3- Why did you add a font size to the textbox? A: To make the design look better,try to remove it and see by your self. 4- Can I register the script at codebehind? A: yes you can 5- I see you have added these two lines,what they do? $("#<%= TextBox1.ClientID %>").attr("readonly", "readonly"); $("#<%= TextBox1.ClientID %>").attr("unselectable", "on"); A:The first line will make the textbox not editable by the user,the second will block the blinking typing cursor from appearing if the user clicked on the textbox,you will notice that both lines are necessary to be used together,you can't just use one of them...for logical reasons of course. Finally,I hope everyone liked the article and as always,your feedbacks are always welcomed and if anyone have any suggestions or made any modifications that might be useful for anyone else then please post it at at the author's website and post a reference to your post here.

  • jQuery autocomplete disabled makes autocomplete partially transparent, not disabled

    - by Ryan Giglio
    I'm using the jQuery UI's "autocomplete" function on a search on my site. When you change a radio button from 'area search" to "name search" I want it to disable the autocomplete, and re-enable it when you switch back. However, when you disable the autocomplete it doesn't hide the dropdown, it just dims it to 20% opacity or so. Here's my javascript: var allFields = new Array(<?php echo $allFields ?>); $(document).ready(function() { if ($("input[name='searchType']:checked").val() == 'areaCode') { $("#siteSearch").autocomplete({ source: allFields, minLength: 2 }); } $("input[name='searchType']").change(function(){ if ($("input[name='searchType']:checked").val() == 'areaCode') { $( "#siteSearch" ).autocomplete( "option", "disabled", false ); alert("enabled"); } else { $( "#siteSearch" ).autocomplete( "option", "disabled", true ); alert("disabled"); } }); }); You can see it happening at http://crewinyourcode.com First you have to chose an area code to search, and then you can see the issue.

  • jquery ui cannot reload current tab

    - by 0plus1
    I need to reload the current tab in jquery ui (loaded with ajax). I'm doing this: function reloadtab(){ $('#tabs').tabs('load', $('#tabs').tabs('option', 'selected')); } Before you begin wondering: $('#tabs').tabs('option', 'selected'); returns 3. When I call reloadtab() I get no error, it simply doesn't work. Why does this happens? Thank you very much EDIT: I'm an idiot, it was working, was a problem with cache. Sorry.

  • jQuery animate() - multiple selectors and variables, a unique animate() call

    - by ozke
    Hi guys, I am resizing several divs in a loop with animate() in jQuery. At the same time I am moving (left property, no resizing at all) the div where they are contained. Problem is, despite they have same duration the resize animate calls finish before the move call. They are out of sync. Is there any way of creating a list of selectors and its properties and then run a unique animate() call? Or, is there any alternative to make multiple animations happen at the same time? I've seen there's a property called step that happens every time animate loop happens but, again, each animate() call has it's own step call. Thanks in advance :)

  • Using the OAM Mobile & Social SDK to secure native mobile apps - Part 2 : OAM Mobile & Social Server configuration

    - by kanishkmahajan
    Objective  In the second part of this blog post I'll now cover configuration of OAM to secure our sample native apps developed using the iOS SDK. First, here are some key server side concepts: Application Profiles: An application profile is a logical representation of your application within OAM server. It could be a web (html/javascript) or native (iOS or Android) application. Applications may have different requirements for AuthN/AuthZ, and therefore each application that interacts with OAM Mobile & Social REST services must be uniquely defined. Service Providers: Service providers represent the back end services that are accessed by applications. With OAM Mobile & Social these services are in the areas of authentication, authorization and user profile access. A Service Provider then defines a type or class of service for authentication, authorization or user profiles. For example, the JWTAuthentication provider performs authentication and returns JWT (JSON Web Tokens) to the application. In contrast, the OAMAuthentication also provides authentication but uses OAM SSO tokens Service Profiles:  A Service Profile is a logical envelope that defines a service endpoint URL for a service provider for the OAM Mobile & Social Service. You can create multiple service profiles for a service provider to define token capabilities and service endpoints. Each service provider instance requires atleast one corresponding service profile.The  OAM Mobile & Social Service includes a pre-configured service profile for each pre-configured service provider. Service Domains: Service domains bind together application profiles and service profiles with an optional security handler. So now let's configure the OAM server. Additional details are in the OAM Documentation and this post simply provides an outline of configuration tasks required to configure OAM for securing native apps.  Configuration  Create The Application Profile Log on to the Oracle Access Management console and from System Configuration -> Mobile and Social -> Mobile Services, select "Create" under Application Profiles. You would do this  step twice - once for each of the native apps - AvitekInventory and AvitekScheduler. Enter the parameters for the new Application profile: Name:  The application name. In this example we use 'InventoryApp' for the AvitekInventory app and 'SchedulerApp' for the AvitekScheduler app. The application name configured here must match the application name in the settings for the deployed iOS application. BaseSecret: Enter a password here. This does not need to match any existing password. It is used as an encryption key between the client and the OAM server.  Mobile Configuration: Enable this checkbox for any mobile applications. This enables the SDK to collect and send Mobile specific attributes to the OAM server.  Webview: Controls the type of browser that the iOS application will use. The embedded browser (default) will render the browser within the application. External will use the system standalone browser. External can sometimes be preferable for debugging URLScheme: The URL scheme associated with the iOS apps that is also used as a custom URL scheme to register O/S handlers that will take control when OAM transfers control to device. For the AvitekInventory and the AvitekScheduler apps I used osa:// and client:// respectively. You set this scheme in Xcode while developing your iOS Apps under Info->URL Types.  Bundle Identifier : The fully qualified name of your iOS application. You typically set this when you create a new Xcode project or under General->Identity in Xcode. For the AvitekInventory and AvitekScheduler apps these were com.us.oracle.AvitekInventory and com.us.oracle.AvitekScheduler respectively.  Create The Service Domain Select create under Service domains. Create a name for your domain (AvitekDomain is what I've used). The name configured must match the service domain set in the iOS application settings. Under "Application Profile Selection" click the browse button. Choose the application profiles that you created in the previous step one by one. Set the InventoryApp as the SSO agent (with an automatic priority of 1) and the SchedulerApp as the SSO client. This associates these applications with this service domain and configures them in a 'circle of trust'.  Advance to the next page of the wizard to configure the services for this domain. For this example we will use the following services:  Authentication:   This will use the JWT (JSON Web Token) format authentication provider. The iOS application upon successful authentication will receive a signed JWT token from OAM Mobile & Social service. This token will be used in subsequent calls to OAM. Use 'MobileOAMAuthentication' here. Authorization:  The authorization provider. The SDK makes calls to this provider endpoint to obtain authorization decisions on resource requests. Use 'OAMAuthorization' here. User Profile Service:  This is the service that provides user profile services (attribute lookup, attribute modification). It can be any directory configured as a data source in OAM.  And that's it! We're done configuring our native apps. In the next section, let's look at some additional features that were mentioned in the earlier post that are automated by the SDK for the app developer i.e. these are areas that require no additional coding by the app developer when developing with the SDK as they only require server side configuration: Additional Configuration  Offline Authentication Select this option in the service domain configuration to allow users to log in and authenticate to the application locally. Clear the box to block users from authenticating locally. Strong Authentication By simply selecting the OAAMSecurityHandlerPlugin while configuring mobile related Service Domains, the OAM Mobile&Social service allows sophisticated device and client application registration logic as well as the advanced risk and fraud analysis logic found in OAAM to be applied to mobile authentication. Let's look at some scenarios where the OAAMSecurityHandlerPlugin gets used. First, when we configure OAM and OAAM to integrate together using the TAP scheme, then that integration kicks off by selecting the OAAMSecurityHandlerPlugin in the mobile service domain. This is how the mobile device is now prompted for KBA,OTP etc depending on the TAP scheme integration and the OAM users registered in the OAAM database. Second, when we configured the service domain, there were claim attributes there that are already pre-configured in OAM Mobile&Social service and we simply accepted the default values- these are the set of attributes that will be fetched from the device and passed to the server during registration/authentication as device profile attributes. When a mobile application requests a token through the Mobile Client SDK, the SDK logic will send the Device Profile attributes as a part of an HTTP request. This set of Device Profile attributes enhances security by creating an audit trail for devices that assists device identification. When the OAAM Security Plug-in is used, a particular combination of Device Profile attribute values is treated as a device finger print, known as the Digital Finger Print in the OAAM Administration Console. Each finger print is assigned a unique fingerprint number. Each OAAM session is associated with a finger print and the finger print makes it possible to log (and audit) the devices that are performing authentication and token acquisition. Finally, if the jail broken option is selected while configuring an application profile, the SDK detects a device is jail broken based on configured policy and if the OAAM handler is configured the plug-in can allow or block access to client device depending on the OAAM policy as well as detect blacklisted, lost or stolen devices and send a wipeout command that deletes all the mobile &social relevant data and blocks the device from future access. 1024x768 Social Logins Finally, let's complete this post by adding configuration to configure social logins for mobile applications. Although the Avitek sample apps do not demonstrate social logins this would be an ideal exercise for you based on the sample code provided in the earlier post. I'll cover the server side configuration here (with Facebook as an example) and you can retrofit the code to accommodate social logins by following the steps outlined in "Invoking Authentication Services" and add code in LoginViewController and maybe create a new delegate - AvitekRPDelegate based on the description in the previous post. So, here all you will need to do is configure an application profile for social login, configure a new service domain that uses the social login application profile, register the app on Facebook and finally configure the Facebook OAuth provider in OAM with those settings. Navigate to Mobile and Social, click on "Internet Identity Services" and create a new application profile. Here are the relevant parameters for the new application profile (-also we're not registering the social user in OAM with this configuration below, however that is a key feature as well): Name:  The application name. This must match the name of the of mobile application profile created for your application under Mobile Services. We used InventoryApp for this example. SharedSecret: Enter a password here. This does not need to match any existing password. It is used as an encryption key between the client and the OAM Mobile and Social service.  Mobile Application Return URL: After the Relying Party (social) login, the OAM Mobile & Social service will redirect to the iOS application using this URI. This is defined under Info->URL type and we used 'osa', so we define this here as 'osa://' Login Type: Choose to allow only internet identity authentication for this exercise. Authentication Service Endpoint : Make sure that /internetidentityauthentication is selected. Login to http://developers.facebook.com using your Facebook account and click on Apps and register the app as InventoryApp. Note that the consumer key and API secret gets generated automatically by the Facebook OAuth server. Navigate back to OAM and under Mobile and Social, click on "Internet Identity Services" and edit the Facebook OAuth Provider. Add the consumer key and API secret from the Facebook developers site to the Facebook OAuth Provider: Navigate to Mobile Services. Click on New to create a new service domain. In this example we call the domain "AvitekDomainRP". The type should be 'Mobile Application' and the application credential type 'User Token'. Add the application "InventoryApp" to the domain. Advance the next page of the wizard. Select the  default service profiles but ensure that the Authentication Service is set to 'InternetIdentityAuthentication'. Finish the creation of the service domain.

  • jQuery event handler queue

    - by resopollution
    Overview of the problem In jQuery, the order in which you bind a handler is the order in which they will be executed if you are binding to the same element. For example: $('#div1').bind('click',function(){ // code runs first }); $('#div1').bind('click',function(){ // code runs second }); But what if I want the 2nd bound code to run first? . My current solution Currently, my solution is to modify the event queue: $.data(domElement, 'events')['click'].unshift({ type : 'click', guid : null, namespace : "", data : undefined, handler: function() { // code } }); . Question Is there anything potentially wrong with my solution? Can I safely use null as a value for the guid? Thanks in advance. .

  • Change the default Icon on your jQuery UI Accordion

    - by hajan
    I've got this question in one of my previous blogs posted here (the same blog is posted on codeasp.net too), dealing with jQuery UI Accordion and I thought it's nice to recap this in a blog post so that I will have it documented for further reference. In the previous blog, I'm creating tabs content navigation using jQuery UI Accordion. So, it's quite simple code and all I do there is calling accordion() function. <script language="javascript" type="text/javascript">     $(function() {         $("#products").accordion();     }); </script> The default image icons for each item is the arrow. The accordion uses the right arrow and down arrow images. So, what we should do in order to change them? JQuery UI Accordion contains option with name icons that has header and headerSelected properties. We can override them with either the existing classes from jQuery UI themes or with our own. 1. Using existing jQuery UI Theme classes - Open the follownig link: http://jqueryui.com/themeroller/#icons You will see the icons available in the jQuery UI theme. Mouse over on each icon and you will see the class name for each icon. As you can see, each icon has class name constructed in the following way: ui-icon-<name> All icons in one image - In our example, I will use ui-icon-circle-plus  and ui-icon-circle-minus (plus and minus icons). - Lets set the icons <script language="javascript" type="text/javascript">     $(function() {         //initialize accordion                 $("#products").accordion();         //set accordion header options         $("#products").accordion("option", "icons",         { 'header': 'ui-icon-circle-plus', 'headerSelected': 'ui-icon-circle-minus' });     }); </script> From the code above, you can see that I first intialize the accordion plugin, and after I override the default icons with the ui-icon-circle-plyus for header and ui-icon-circle-minus for headerSelected. Here is the end result: So, now you see we have the plus/minus circle icons for the default header state and the selected header state.   2. Add my own icons - If you want to add your own icons, you can do that by creating your own custom css classes. - Lets create classes for both, the header default state and header selected state <style type="text/css">     .defaultIcon     {         background-image: url(images/icons/defaultIcon.png) !important;         width: 25px;         height: 25px;     }     .selectedIcon     {         background-image: url(images/icons/selectedIcon.png) !important;         width: 25px;         height: 25px;     } </style> As you can see, I use my own images placed in images/icons/ folder - default icon - selected icon One very important thing to note here is the !important key added on each background-image property. It's like that in order to give highest importancy to our image so that the default jQuery UI theme icon images will have less importancy and won't be used. And the jQuery code is: <script language="javascript" type="text/javascript">     $(function() {         //initialize accordion                 $("#products").accordion();         //set accordion header options         $("#products").accordion("option", "icons",         { 'header': 'defaultIcon', 'headerSelected': 'selectedIcon' });     }); </script> Note: For both #1 and #2 cases, we use the class names without adding . (dot) at the beginning of the name (as we do with selectors). That's because the the header and headerSelected properties accept classes only as a value, so the rest is done by the plugin itself.

  • jQuery UI Tabs customization for many tabs

    - by Tauren
    I'd like to implement a tab bar using jquery-ui-tabs that has been customised to work like it does on HootSuite. Try this on HootSuite to see what I mean: Log in to your hootsuite.com account Click the + symbol to the right of your tabs Add tabs named "MMMMMMMMMMMMMMMMM" until a "More..." tab appears You'll see this: HootSuite includes the following features, all of which I would like to do: Fit as many tabs as possible onto the screen. Users with larger screens would see more tabs. If they run out of space, a "More..." tab would appear with a drop-down list Clicking onto the More tab would drop down a list of additional tabs Tabs can be dragged and rearranged. Tabs in the More drop-down list can be dragged to the tab bar Delete tabs with a small X next to the tab name Add tabs with a + icon to the right of the last tab I already have a tab bar working that does 4 and 6. I found a Paging Tab Plugin which is pretty cool, but works differently. Does anyone know of plugins or techniques that would help me accomplish the above? My thought is to not really make the More tab a real tab, but just an object that looks like a tab. I'd add logic to the tabs.add method to calculate if another tab can fit. If it can't, then I would add the details of the tab to my separate "More" list. There'd be a fair amount of effort to get this all working, so if there are any plugins that would help, I'd love to hear about them.

  • Looking into the JQuery Overlays Plugin

    - by nikolaosk
    I have been using JQuery for a couple of years now and it has helped me to solve many problems on the client side of web development.  You can find all my posts about JQuery in this link. In this post I will be providing you with a hands-on example on the JQuery Overlays Plugin.If you want you can have a look at this post, where I describe the JQuery Cycle Plugin.You can find another post of mine talking about the JQuery Carousel Lite Plugin here. Another post of mine regarding the JQuery Image Zoom Plugin can be found here.I will be writing more posts regarding the most commonly used JQuery Plugins. With the JQuery Overlays Plugin we can provide the user (overlay) with more information about an image when the user hovers over the image. I have been using extensively this plugin in my websites. In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like. You can use Visual Studio 2012 Express edition. You can download it here.  You can download this plugin from this link. I launch Expression Web 4.0 and then I type the following HTML markup (I am using HTML 5) <html lang="en"> <head>    <link rel="stylesheet" href="ImageOverlay.css" type="text/css" media="screen" />    <script type="text/javascript" src="jquery-1.8.3.min.js"></script>    <script type="text/javascript" src="jquery.ImageOverlay.min.js"></script>         <script type="text/javascript">        $(function () {            $("#Liverpool").ImageOverlay();        });    </script>   </head><body>    <ul id="Liverpool" class="image-overlay">        <li>            <a href="www.liverpoolfc.com">                <img alt="Liverpool" src="championsofeurope.jpg" />                <div class="caption">                    <h3>Liverpool Football club</h3>                    <p>The greatest club in the world</p>                </div>            </a>        </li>    </ul></body></html> This is a very simple markup. I have added references to the JQuery library (current version is 1.8.3) and the JQuery Overlays Plugin. Then I add 1 image in the element with "id=Liverpool". There is a caption class as well, where I place the text I want to show when the mouse hovers over the image. The caption class and the Liverpool id element are styled in the ImageOverlay.css file that can also be downloaded with the plugin.You can style the various elements of the html markup in the .css file. The Javascript code that makes it all happen follows.   <script type="text/javascript">        $(function () {            $("#Liverpool").ImageOverlay();        });    </script>        I am just calling the ImageOverlay function for the Liverpool ID element.The contents of ImageOverlay.css file follow .image-overlay { list-style: none; text-align: left; }.image-overlay li { display: inline; }.image-overlay a:link, .image-overlay a:visited, .image-overlay a:hover, .image-overlay a:active { text-decoration: none; }.image-overlay a:link img, .image-overlay a:visited img, .image-overlay a:hover img, .image-overlay a:active img { border: none; }.image-overlay a{    margin: 9px;    float: left;    background: #fff;    border: solid 2px;    overflow: hidden;    position: relative;}.image-overlay img{    position: absolute;    top: 0;    left: 0;    border: 0;}.image-overlay .caption{    float: left;    position: absolute;    background-color: #000;    width: 100%;    cursor: pointer;    /* The way to change overlay opacity is the follow properties. Opacity is a tricky issue due to        longtime IE abuse of it, so opacity is not offically supported - use at your own risk.         To play it safe, disable overlay opacity in IE. */    /* For Firefox/Opera/Safari/Chrome */    opacity: .8;    /* For IE 5-7 */    filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=80);    /* For IE 8 */    -MS-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=80)";}.image-overlay .caption h1, .image-overlay .caption h2, .image-overlay .caption h3,.image-overlay .caption h4, .image-overlay .caption h5, .image-overlay .caption h6{    margin: 10px 0 10px 2px;    font-size: 26px;    font-weight: bold;    padding: 0 0 0 5px;    color:#92171a;}.image-overlay p{    text-indent: 0;    margin: 10px;    font-size: 1.2em;} It couldn't be any simpler than that. I view my simple page in Internet Explorer 10 and it works as expected. I have tested this simple solution in all major browsers and it works fine.Have a look at the picture below. You can test it yourself and see the results in your favorite browser. Hope it helps!!!

  • jQuery.post() issues with passing data to jQuery UI

    - by solefald
    Hello, I am trying to get jQuery.post() to run my php script and then open a jQuery UI dialog with the data that php script returns. Its supposed to come back as a form with a table and a textarea in it. It works great with alert(data); and i get a pop-up with all my data. The problem starts if i turn off alert(). Now it opens 2 dialogs. One containing only the table, without textarea, and the second one absolutely empty. What am i doing wrong here? How come all my data shows up in the alert(), but not in dialog? What do i need to do to fix it? Oh, and do i need to also include $.ajax() before the $.post()? Thank you. $.post("/path/to/script.php", { id: this.id, value: value }, function(data){ // THIS WORKS //alert(data); // THIS DOES NOT WORK $(data).dialog({ autoOpen: true, width: 400, modal: true, position: 'center', resizable: false, draggable: true, title: 'Pending Changes' }); } );

  • Using jQuery to Insert a New Database Record

    - by Stephen Walther
    The goal of this blog entry is to explore the easiest way of inserting a new record into a database using jQuery and .NET. I’m going to explore two approaches: using Generic Handlers and using a WCF service (In a future blog entry I’ll take a look at OData and WCF Data Services). Create the ASP.NET Project I’ll start by creating a new empty ASP.NET application with Visual Studio 2010. Select the menu option File, New Project and select the ASP.NET Empty Web Application project template. Setup the Database and Data Model I’ll use my standard MoviesDB.mdf movies database. This database contains one table named Movies that looks like this: I’ll use the ADO.NET Entity Framework to represent my database data: Select the menu option Project, Add New Item and select the ADO.NET Entity Data Model project item. Name the data model MoviesDB.edmx and click the Add button. In the Choose Model Contents step, select Generate from database and click the Next button. In the Choose Your Data Connection step, leave all of the defaults and click the Next button. In the Choose Your Data Objects step, select the Movies table and click the Finish button. Unfortunately, Visual Studio 2010 cannot spell movie correctly :) You need to click on Movy and change the name of the class to Movie. In the Properties window, change the Entity Set Name to Movies. Using a Generic Handler In this section, we’ll use jQuery with an ASP.NET generic handler to insert a new record into the database. A generic handler is similar to an ASP.NET page, but it does not have any of the overhead. It consists of one method named ProcessRequest(). Select the menu option Project, Add New Item and select the Generic Handler project item. Name your new generic handler InsertMovie.ashx and click the Add button. Modify your handler so it looks like Listing 1: Listing 1 – InsertMovie.ashx using System.Web; namespace WebApplication1 { /// <summary> /// Inserts a new movie into the database /// </summary> public class InsertMovie : IHttpHandler { private MoviesDBEntities _dataContext = new MoviesDBEntities(); public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; // Extract form fields var title = context.Request["title"]; var director = context.Request["director"]; // Create movie to insert var movieToInsert = new Movie { Title = title, Director = director }; // Save new movie to DB _dataContext.AddToMovies(movieToInsert); _dataContext.SaveChanges(); // Return success context.Response.Write("success"); } public bool IsReusable { get { return true; } } } } In Listing 1, the ProcessRequest() method is used to retrieve a title and director from form parameters. Next, a new Movie is created with the form values. Finally, the new movie is saved to the database and the string “success” is returned. Using jQuery with the Generic Handler We can call the InsertMovie.ashx generic handler from jQuery by using the standard jQuery post() method. The following HTML page illustrates how you can retrieve form field values and post the values to the generic handler: Listing 2 – Default.htm <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Add Movie</title> <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> </head> <body> <form> <label>Title:</label> <input name="title" /> <br /> <label>Director:</label> <input name="director" /> </form> <button id="btnAdd">Add Movie</button> <script type="text/javascript"> $("#btnAdd").click(function () { $.post("InsertMovie.ashx", $("form").serialize(), insertCallback); }); function insertCallback(result) { if (result == "success") { alert("Movie added!"); } else { alert("Could not add movie!"); } } </script> </body> </html>     When you open the page in Listing 2 in a web browser, you get a simple HTML form: Notice that the page in Listing 2 includes the jQuery library. The jQuery library is included with the following SCRIPT tag: <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> The jQuery library is included on the Microsoft Ajax CDN so you can always easily include the jQuery library in your applications. You can learn more about the CDN at this website: http://www.asp.net/ajaxLibrary/cdn.ashx When you click the Add Movie button, the jQuery post() method is called to post the form data to the InsertMovie.ashx generic handler. Notice that the form values are serialized into a URL encoded string by calling the jQuery serialize() method. The serialize() method uses the name attribute of form fields and not the id attribute. Notes on this Approach This is a very low-level approach to interacting with .NET through jQuery – but it is simple and it works! And, you don’t need to use any JavaScript libraries in addition to the jQuery library to use this approach. The signature for the jQuery post() callback method looks like this: callback(data, textStatus, XmlHttpRequest) The second parameter, textStatus, returns the HTTP status code from the server. I tried returning different status codes from the generic handler with an eye towards implementing server validation by returning a status code such as 400 Bad Request when validation fails (see http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html ). I finally figured out that the callback is not invoked when the textStatus has any value other than “success”. Using a WCF Service As an alternative to posting to a generic handler, you can create a WCF service. You create a new WCF service by selecting the menu option Project, Add New Item and selecting the Ajax-enabled WCF Service project item. Name your WCF service InsertMovie.svc and click the Add button. Modify the WCF service so that it looks like Listing 3: Listing 3 – InsertMovie.svc using System.ServiceModel; using System.ServiceModel.Activation; namespace WebApplication1 { [ServiceBehavior(IncludeExceptionDetailInFaults=true)] [ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class MovieService { private MoviesDBEntities _dataContext = new MoviesDBEntities(); [OperationContract] public bool Insert(string title, string director) { // Create movie to insert var movieToInsert = new Movie { Title = title, Director = director }; // Save new movie to DB _dataContext.AddToMovies(movieToInsert); _dataContext.SaveChanges(); // Return movie (with primary key) return true; } } }   The WCF service in Listing 3 uses the Entity Framework to insert a record into the Movies database table. The service always returns the value true. Notice that the service in Listing 3 includes the following attribute: [ServiceBehavior(IncludeExceptionDetailInFaults=true)] You need to include this attribute if you want to get detailed error information back to the client. When you are building an application, you should always include this attribute. When you are ready to release your application, you should remove this attribute for security reasons. Using jQuery with the WCF Service Calling a WCF service from jQuery requires a little more work than calling a generic handler from jQuery. Here are some good blog posts on some of the issues with using jQuery with WCF: http://encosia.com/2008/06/05/3-mistakes-to-avoid-when-using-jquery-with-aspnet-ajax/ http://encosia.com/2008/03/27/using-jquery-to-consume-aspnet-json-web-services/ http://weblogs.asp.net/scottgu/archive/2007/04/04/json-hijacking-and-how-asp-net-ajax-1-0-mitigates-these-attacks.aspx http://www.west-wind.com/Weblog/posts/896411.aspx http://www.west-wind.com/weblog/posts/324917.aspx http://professionalaspnet.com/archive/tags/WCF/default.aspx The primary requirement when calling WCF from jQuery is that the request use JSON: The request must include a content-type:application/json header. Any parameters included with the request must be JSON encoded. Unfortunately, jQuery does not include a method for serializing JSON (Although, oddly, jQuery does include a parseJSON() method for deserializing JSON). Therefore, we need to use an additional library to handle the JSON serialization. The page in Listing 4 illustrates how you can call a WCF service from jQuery. Listing 4 – Default2.aspx <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Add Movie</title> <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script> <script src="Scripts/json2.js" type="text/javascript"></script> </head> <body> <form> <label>Title:</label> <input id="title" /> <br /> <label>Director:</label> <input id="director" /> </form> <button id="btnAdd">Add Movie</button> <script type="text/javascript"> $("#btnAdd").click(function () { // Convert the form into an object var data = { title: $("#title").val(), director: $("#director").val() }; // JSONify the data data = JSON.stringify(data); // Post it $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "MovieService.svc/Insert", data: data, dataType: "json", success: insertCallback }); }); function insertCallback(result) { // unwrap result result = result["d"]; if (result === true) { alert("Movie added!"); } else { alert("Could not add movie!"); } } </script> </body> </html> There are several things to notice about Listing 4. First, notice that the page includes both the jQuery library and Douglas Crockford’s JSON2 library: <script src="Scripts/json2.js" type="text/javascript"></script> You need to include the JSON2 library to serialize the form values into JSON. You can download the JSON2 library from the following location: http://www.json.org/js.html When you click the button to submit the form, the form data is converted into a JavaScript object: // Convert the form into an object var data = { title: $("#title").val(), director: $("#director").val() }; Next, the data is serialized into JSON using the JSON2 library: // JSONify the data var data = JSON.stringify(data); Finally, the form data is posted to the WCF service by calling the jQuery ajax() method: // Post it $.ajax({   type: "POST",   contentType: "application/json; charset=utf-8",   url: "MovieService.svc/Insert",   data: data,   dataType: "json",   success: insertCallback }); You can’t use the standard jQuery post() method because you must set the content-type of the request to be application/json. Otherwise, the WCF service will reject the request for security reasons. For details, see the Scott Guthrie blog post: http://weblogs.asp.net/scottgu/archive/2007/04/04/json-hijacking-and-how-asp-net-ajax-1-0-mitigates-these-attacks.aspx The insertCallback() method is called when the WCF service returns a response. This method looks like this: function insertCallback(result) {   // unwrap result   result = result["d"];   if (result === true) {       alert("Movie added!");   } else {     alert("Could not add movie!");   } } When we called the jQuery ajax() method, we set the dataType to JSON. That causes the jQuery ajax() method to deserialize the response from the WCF service from JSON into a JavaScript object automatically. The following value is passed to the insertCallback method: {"d":true} For security reasons, a WCF service always returns a response with a “d” wrapper. The following line of code removes the “d” wrapper: // unwrap result result = result["d"]; To learn more about the “d” wrapper, I recommend that you read the following blog posts: http://encosia.com/2009/02/10/a-breaking-change-between-versions-of-aspnet-ajax/ http://encosia.com/2009/06/29/never-worry-about-asp-net-ajaxs-d-again/ Summary In this blog entry, I explored two methods of inserting a database record using jQuery and .NET. First, we created a generic handler and called the handler from jQuery. This is a very low-level approach. However, it is a simple approach that works. Next, we looked at how you can call a WCF service using jQuery. This approach required a little more work because you need to serialize objects into JSON. We used the JSON2 library to perform the serialization. In the next blog post, I want to explore how you can use jQuery with OData and WCF Data Services.

  • Saving mobile application data when no service?

    - by Abe Miessler
    Say I have a mobile application that allows users to enter information which is then uploaded to a central location. I had planned on building this using only HTML5 and javascript (non-native app), but I'm assuming if someone is in an area where there is no service they simply will not be able to use the app. As a work around would it be possible to write a native app that saves the information on the device and then uploads it whenever service returns? If so, is it possible to write a native app entirely in HTML5 and Javascript that does this?

  • Hide Address bar for Xpages Mobile Web Application on Ipad (iOS5) and Mobile safari (v5.1)

    - by prasad katankot
    With reference to the question I asked couple of days back, it seems to me that address bar cannot be hidden from a xpages mobile web application when it is launched from a href link. Choice is limited to href as "location.assign" or any javascript will not work on mails accessed by lotus traveller. I tried almost 20 different variations published by other experts to hide address bar and none seems to work. Am I wrong in stating that "it is not possible to hide address bar in Xpages mobile web application on ipad when not launched from home screen"?

  • jQuery UI sortable('cancel') - this.helper is null

    - by Kerry
    I am trying to disable a sortable element from sorting when it has been double clicked. When I try to disable it, even without a condition, it gives me the error 'this.helper is null'. $('.roundedBox:first', division).sortable({ start: function( event, ui ) { if( true === true ) { $(this).sortable('cancel'); } $(this).parent().data( 'sorting', true ); }, stop: function() { $(this).parent().data( 'sorting', false ); }, items: '.department', update: function() {}, placeholder: 'department-placeholder' }) Any ideas on how I can do this? I don't need it to be this method. Literally anything thing that stops it will work. The problem is, sorting starts on a single click, but I have another action bound to double click. If it's double clicked, I don't want it to drag.
