  • Designing a fluid Javascript interface to abstract away the asynchronous nature of AJAX

    - by Anurag
    How would I design an API to hide the asynchronous nature of AJAX and HTTP requests, or basically delay it to provide a fluid interface. To show an example from Twitter's new Anywhere API: // get @ded's first 20 statuses, filter only the tweets that // mention photography, and render each into an HTML element T.User.find('ded').timeline().first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); function filterer(status) { return status.text.match(/photography/); } vs this (asynchronous nature of each call is clearly visible) T.User.find('ded', function(user) { user.timeline(function(statuses) { statuses.first(20).filter(filterer).each(function(status) { $('div#tweets').append('<p>' + status.text + '</p>'); }); }); }); It finds the user, gets their tweet timeline, filters only the first 20 tweets, applies a custom filter, and ultimately uses the callback function to process each tweet. I am guessing that a well designed API like this should work like a query builder (think ORMs) where each function call builds the query (HTTP URL in this case), until it hits a looping function such as each/map/etc., the HTTP call is made and the passed in function becomes the callback. An easy development route would be to make each AJAX call synchronous, but that's probably not the best solution. I am interested in figuring out a way to make it asynchronous, and still hide the asynchronous nature of AJAX.

  • TinyMCE + jQuery + custom plugin = tinymce is undefined?

    - by user368691
    The problem occurs when I try to create small plugin to allow me toggle on and off WYSIWYG on all textareas in the website. //$('form.default textarea').each(function(){ // console.log( $('<a href="#">Enable WYSIWYG editor</a>').insertAfter('form.default textarea').prev('textarea.wysiwyg').tinymce().hide() ); //}); The full (a bit simplified) code looks like this: $('textarea.wysiwyg').tinymce({ skin : 'cirkuit', theme : 'advanced', plugins : 'pagebreak,style,layer,advlink,inlinepopups,contextmenu,paste,directionality,noneditable,nonbreaking,xhtmlxtras,template', // Theme options theme_advanced_buttons1 : 'formatselect,fontsizeselect,forecolor,|,bold,italic,strikethrough,|,bullist,numlist,|,justifyleft,justifycenter,justifyright,|,link,unlink,|,image,|,code,paste,pastetext,pasteword,removeformat,|,backcolor,|,underline,justifyfull,sup,|,outdent,indent,|,hr,charmap,|,undo,redo', theme_advanced_buttons2 : '', theme_advanced_buttons3 : '', theme_advanced_toolbar_location : 'top', theme_advanced_toolbar_align : 'left', theme_advanced_statusbar_location: 'bottom', theme_advanced_resizing : true, theme_advanced_resize_horizontal : false, height : 500, theme_advanced_resizing_min_height : 500, document_base_url : 'http://static.<?=$settings['system_host']?>/' }); $('textarea.wysiwyg').each(function() { $(this).tinymce().hide(); }); What is the error? FireBug says that tinymce() in undefined; this message occurs in each() loop. Thus, tinymce() is actually initialized. I am really lost towards, what could be causing this.

  • Ajax/PHP contact form not able to send mail

    - by Steph
    The funny thing is it did work for one evening. I contacted my host, and they are saying there's no reason it should not be working. I have also attempted to test it in Firebug, but it seemed to be sending. And I specifically put the email address (hosted in my domain) on my email safe list, so that is not the culprit either. Would anyone here take a look at it for me? I'd be so grateful. In the header I have: <script type="text/javascript"> $(document).ready(function() { var options = { target: '#alert' }; $('#contactForm').ajaxForm(options); }); $.fn.clearForm = function() { return this.each(function() { var type = this.type, tag = this.tagName.toLowerCase(); if (tag == 'form') return $(':input',this).clearForm(); if (type == 'text' || type == 'password' || tag == 'textarea') this.value = ''; else if (type == 'checkbox' || type == 'radio') this.checked = false; else if (tag == 'select') this.selectedIndex = -1; }); }; </script> Here is the actual form: <form id="contactForm" method="post" action="sendmail.php"> <fieldset> <p>Email Me</p> <div id="fieldset_container"> <label for="name">Your Name:</label> <input type="text" name="name" id="name" /><br /><br /> <label for="email">Email:</label> <input type="text" name="email" id="email" /><br /><br /> <span style="display:none;"> <label for="last">Honeypot:</label> <input type="text" name="last" value="" id="last" /> </span><br /><br /> <label for="message">Comments &amp; Inquiries:</label> <textarea name="message" id="message" cols="" rows=""></textarea><br/> </div> <div id="submit_button"> <input type="submit" name="submit" id="submit" value="Send It" /> </div> </fieldset> </form> <div class="message"><div id="alert"></div></div> Here is the code from my validating page, sendmail.php: <?php // Who you want to recieve the emails from the form.

  • Run ajax scripts on page when navigating with ajax?

    - by Oskar Kjellin
    I got a bit of an issue in my ASP.NET MVC project. I have a chat div in the bottom right corner (like facebook), and of course I do not want this to reload when navigating to all my navigation is ajax. The problem I am facing is that I use the following code on the top of the view page: <script type="text/javascript"> $(document).ready(function() { $('#divTS').hide(); $('a#showTS').click(function() { $('#divTS').slideToggle(400); return false; }); }); </script> The problem is that this code is only loaded with ajax and does not seem to fire? I would like to run all scripts in the newly loaded view, just as if I hadn't navigated with ajax. I cannot put this in the site.master as it only loads once and then probably the divs I am trying to hide doesn't exist. Is there a good way to run scripts in the ajax-loaded div?

  • JQUERY, AutoSuggest that doesn't kill the Server on ever keyup

    - by nobosh
    I'm working to build a JQUERY enabled AutoSuggest plugin, inspired by Apple's spotlight. Here is the general code: $(document).ready(function() { $('#q').bind('keyup', function() { if( $(this).val().length == 0) { // Hide the q-suggestions box $('#q-suggestions').fadeOut(); } else { // Show the AJAX Spinner $("#q").css("background-image","url(/images/ajax-loader.gif)"); $.ajax({ url: '/search/spotlight/', data: {"q": $(this).val()}, success: function(data) { $('#q-suggestions').fadeIn(); // Show the q-suggestions box $('#q-suggestions').html(data); // Fill the q-suggestions box // Hide the AJAX Spinner $("#q").css("background-image","url(/images/icon-search.gif)"); } }); } }); The issue I want to solve well & elegantly, is not killing the sever. Right now the code above hits the server every time you type a key and does not wait for you to essentially finish typing. What's the best way to solve this? A. Kill previous AJAX request? B. Some type of AJAX caching? C. Adding some type of delay to only submit .AJAX() when the person has stopped typing for 300ms or so? Thanks

  • Remove clear button (grey x) to the right of UISearchBar when cancel button tapped

    - by David Foster
    Right, to begin my question, here's some screenies of the problem already solved by the Spotify app: Spotify's Step 1: Standard UISearchBar not in editing mode. Spotify's Step 2: UISearchBar now in editing mode. Search term entered. Cancel button slides in from the right, and the clear button (grey x) appears. Spotify's Step 3: Cancel button pressed; keyboard slides out and the search bar is no longer in editing mode. Search term remains and the grey x button is now hidden. At present, the following code fires off when my cancel button is pressed: - (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar { [searchBar resignFirstResponder]; [searchBar setShowsCancelButton:NO animated:YES]; } Which results in: My Step 3: Search bar now not in editing mode. Cancel button and keyboard has slid out. Search term remains but so does the grey x. So, my question is this: given that -resignFirstResponder (and -endEditing:, FYI) does not hide the grey x button when a search bar has had text entered into it, how does one hide it? Thanks again, friends.

  • Navigation view system with webview problem with touches!

    - by Gonçalo Falcão
    Hello i have search everything and i didn't figure this out! I have a tab bar controller with 5 navigation controlls, in one of the navigation control, i have a view, with a table view inside, and when i click that item i push a new view, that view have view -webview -view i create that second view(is transperant) because i need to handle a single tap to hide my toolbar and navigation bar, and the webview was eating all the touches! I put that view and implement on the view controller -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch* touch = [touches anyObject]; if(touch.tapCount == 2){ [NSObject cancelPreviousPerformRequestsWithTarget:self]; } [[wv.subviews objectAtIndex:0] touchesBegan:touches withEvent:event]; [super touchesBegan:touches withEvent:event]; } -(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ [[wv.subviews objectAtIndex:0] touchesMoved:touches withEvent:event]; [super touchesMoved:touches withEvent:event]; } -(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch* touch = [touches anyObject]; if(touch.tapCount == 1){ [self performSelector:@selector(hideBars) withObject:nil afterDelay:0.3]; } [[wv.subviews objectAtIndex:0] touchesEnded:touches withEvent:event]; [super touchesEnded:touches withEvent:event]; } -(void) touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event{ [[wv.subviews objectAtIndex:0] touchesCancelled:touches withEvent:event]; [super touchesCancelled:touches withEvent:event]; } wv is my UIWebView IBOutlet now i can get the the touches in my controller and send them to my webview. So i thought everything was working, i'm able to scroll, but now when i have links i'm not able to click them. And the webview is detecting the links i have made that test. So any other way to implements this to get the touches in the links, or i should change this workaround to hide the toolbars so i can have the full functionability of the webview? Thks for the help in advance.

  • GLOBAL loading inside each single button with Jquery in ajax calls of asp.net mvc

    - by Ricky
    I have the following scenario: I have a button\link with a image inside like this: <button type="submit" id="myButton" class="button"><img src="../../Content/images/check.png" id="defaultImage" /> SaveData!!!</button> We are OK here! Now what I need to do is: I want on the click that the image change for a loading element that is previously loaded in the page like this: <img id="loadingImage" src="../../Content/images/loader.gif" style="display: none;" alt="loading"/> And then when the load complete turn back the old button image, I ended with this code: function loader() { var $button = $('#myButton'); if (btnState == '1') { $button.find('img').hide(); $button.prepend($('#loadingImage')); $('#loadingImage').css({ 'display': 'inherit' }); btnState = '0'; } else { $button.find('img').hide(); $button.prepend($('#defaultImage')); $('#defaultImage').show(); btnState = '1'; } } This does the trick for ONE SINGLE button(since I pass its ID in the function) but, when I have for example a grid with a button on each line, I found inviable when managing a screen with many buttons do this for each of then. The main question is: How can I make this method general for all buttons/links on one specific class in the page? The goal is: Click a button, get the image and change it and stop(can be manual). I just don't wanna have to Hook ALL buttons.

  • Thumbnails fadein fadeout specific div fade issues

    - by Omikron
    I am using this code to hide and show a div based on which thumbnail you rollover; $(document).ready(function(){ $('div.infodiv').hide(); $(".website_thumbs a").hover( function(){ var name = $(this).attr("name"); $(".infodiv").stop(); $("."+name).fadeIn(); }, function(){ var name = $(this).attr("name"); $("."+name).fadeTo(7000,1).fadeOut(); }); }); The script gets the name attribute from the thumbnail and displays the div with the corresponding class. Each div shares the .infodiv class but also has a class unique to each thumbnail. The functionality is basically where I want it but when you scroll over the thumbnails fast some of the divs get stuck in a kind of half faded-in state and stop working unless i roll over them once - then they slow fade in and they are usable again. I am a bit new to jQuery and would appreciate any help.

  • RadAjaxManager problem when showing/hiding control on page loading

    - by Lukasz Lysik
    I have the webform with dropdown list, label and textbox. Like below: <asp:DropDownList ID="ddlTest" runat="server" AutoPostBack="true"> </asp:DropDownList> <asp:Label ID="lblTest" runat="server" Text="Some text"> </asp:Label> <asp:TextBox ID="edtTest" runat="server"> </asp:TextBox> I want to show/hide label and text box depending on the value selected on dropdown list. So I've added RadAjaxManader: <rad:RadAjaxManager ID="RadAjaxManager1" runat="server"> <AjaxSettings> <rad:AjaxSetting AjaxControlID="ddlTest"> <UpdatedControls> <rad:AjaxUpdatedControl ControlID="lblTest" /> <rad:AjaxUpdatedControl ControlID="edtTest" /> </UpdatedControls> </rad:AjaxSetting> </AjaxSettings> </rad:RadAjaxManager> and procedure "SetupVisibility" which takes value from the dropdown list, does some walidations and desides whether to show or hide the label and the text box. When I use the procedure like this: Protected Sub ddlTest_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlTest.SelectedIndexChanged SetupVisibility() End Sub it works good, but now I want to call SetupVisibility when the page is loaded: Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init SetupVisibility() End Sub The problem occurs in such a scenario: SetupVisibility() hides textbox and label while page is loaded. I change value on ddlTest dropdown list. SetupVisibility() wants to show textbox and label, but then I get the error: Microsoft JScript - runtime error: Cannot update control with ID: ctl00_CPH1_lblTest. The control does not exist. Where is the problem?

  • How do I set YUI2 paginator to select a page other than the first page?

    - by Jeremy Weathers
    I have a YUI DataTable (YUI 2.8.0r4) with AJAX pagination. Each row in the table links to a details/editing page and I want to link from that details page back to the list page that includes the record from the details page. So I have to a) offset the AJAX data correctly and b) tell YAHOO.widget.Paginator which page to select. According to my reading of the YUI API docs, I have to pass in the initialPage configuration option. I've attempted this, but it doesn't take (the data from AJAX is correctly offset, but the paginator thinks I'm on page 1, so clicking "next" takes me from e.g. page 6 to page 2. What am I not doing (or doing wrong)? Here's my DataTable building code: (function() { var columns = [ {key: "retailer", label: "Retailer", sortable: false, width: 80}, {key: "publisher", label: "Publisher", sortable: false, width: 300}, {key: "description", label: "Description", sortable: false, width: 300} ]; var source = new YAHOO.util.DataSource("/sales_data.json?"); source.responseType = YAHOO.util.DataSource.TYPE_JSON; source.responseSchema = { resultsList: "records", fields: [ {key: "url"}, {key: "retailer"}, {key: "publisher"}, {key: "description"} ], metaFields: { totalRecords: "totalRecords" } }; var LoadingDT = function(div, cols, src, opts) { LoadingDT.superclass.constructor.call( this, div, cols, src, opts); // hide the message tbody this._elMsgTbody.style.display = "none"; }; YAHOO.extend(LoadingDT, YAHOO.widget.DataTable, { showTableMessage: function(msg) { $('sales_table_overlay').clonePosition($('sales_table').down('table')). show(); }, hideTableMessage: function() { $('sales_table_overlay').hide(); } }); var table = new LoadingDT("sales_table", columns, source, { initialRequest: "startIndex=125&results=25", dynamicData: true, paginator: new YAHOO.widget.Paginator({rowsPerPage: 25, initialPage: 6}) }); table.handleDataReturnPayload = function(oRequest, oResponse, oPayload) { oPayload.totalRecords = oResponse.meta.totalRecords; return oPayload; }; })();

  • how to match var/id to class

    Hi. I'm new to jquery and, in addition, I think I'm having a brain freeze. I have a number of links with different ids. I want to match the clicked link with a div with the corresponding class so the div will show/hide/toggle as appropriate. I have: <script type="text/javascript"> $(document).ready(function() { $('.folioBox').hide(); $('a.interface').click(function(){ var currentId = $(this).attr('id'); var currentBox = $('.folioBox .' + currentId); $(currentBox).toggle(400); }); }); </script> <a class="interface" id="apple">Apple flavor</a> <a class="interface" id="banana">Banana flavor</a> <a class="interface" id="cherry">Cherry flavor</a> <div class="folioBox apple">content</div> <div class="folioBox banana">content</div> <div class="folioBox cherry">content</div> I just can't get it to work and I can't figure out whether I would be best using match or find or filter.

  • Grouped UITableView Footer Sometimes Hidden On Quick Scroll

    - by jdandrea
    OK, this one is a puzzler. There is one similar post but it's not similar enough to count, so I'm posting this one. :) I've got a grouped UITableView with a header and footer. The footer includes two UIButton views, side-by-side. Nothing major. Now … there is a toggle button in a UIToolbar at the bottom for more/less info in this table view. So I build my index paths to delete/insert with fade row animation, all the usual ingredients, sandwiched between beginUpdates and endUpdates calls on the UITableView … and this works fine! In also happens that my footer can sometimes be pushed off past the bottom of the display. Here's where it gets weird. If I drag my finger up the display, scrolling the view upward, I should see that footer eventually, right? Well … most of the time I do. BUT, if I flick my finger up, for a faster scroll, the footer is missing. Even if you try to tap in that area - no response. However, if I scroll back down again, just to hide that footer (or rather hide the area where the footer would normally be), and then scroll back up, it's there once again! This only happens when inserting rows. If I delete rows, the footer stays put … unless of course it was already hidden and I didn't perform the aforementioned incantation to get it back. :) I am trying to trace through this, but to no avail. I suppose tracing through scroll operations is a bit of a crazy proposition! Perhaps some creative logging … suggestions, anyone? Or is this a known issue in 3.1 where row insert/deletes are concerned? (I don't recall seeing it until 3.1.)

  • Drupal theme preprocess function - primary links

    - by slimcady
    I recently wrote a theme function to add a class to my primary links that works great. I then wrote some css classes to style these links with custom background images. Worked out great. Now comes the problem, the link text for the primary links still is displayed. Normally this isn't a problem as I would just wrap the in a with a custom "hide" class. For example: <span class="hide"><a href="#">Link Text</a></span> So my question is how can I loop through the primary links and wrap the text w/ a <span> like my example? Here's my theme function that I used to add my classes. function zkc_preprocess_page(&$vars, $hook) { // Make a shortcut for the primary links variables $primary_links = $vars['primary_links']; // Loop thru the menu, adding a new class for CSS selectors $i = 1; foreach ($primary_links as $link => $attributes){ // Append the new class to existing classes for each menu item $class = $attributes['attributes']['class'] . " item-$i"; // Add revised classes back to the primary links temp variable $primary_links[$link]['$attributes']['class'] = $class; $i++; } // end the foreach loop // reset the variable to contain the new markup $vars['primary_links'] = $primary_links; }

  • dynamic date formats in eyecon's Bootstrap Datepicker

    - by Jennifer Michelle
    I need to update my datepickers' date format (mm.dd.yyyy etc) using a select box. I am currently using Eyecon's Bootstrap Datepicker because it had the smallest files size that I could find (8k minified), and includes the date formats I need. I also tried to trigger date format changes in several other datepickers without any success. Fiddle: http://jsfiddle.net/Yshy7/8/ Is there an obvious way to trigger a change from the select box to the datepickers? //date format var dateFormat = $('#custom_date_format').val() || "mm/dd/yyyy"; $('#custom_date_format').change(function() { var dateFormat = $(this).val(); }); //start and end dates var nowTemp = new Date(); var now = new Date(nowTemp.getFullYear(), nowTemp.getMonth(), nowTemp.getDate(), 0, 0, 0, 0); var checkin = $('.j-start-date').datepicker({ format: dateFormat, onRender: function(date) { //return date.valueOf() < now.valueOf() ? 'disabled' : ''; } }).on('changeDate', function(ev) { if (ev.date.valueOf() > checkout.date.valueOf()) { var newDate = new Date(ev.date) newDate.setDate(newDate.getDate()); checkout.setValue(newDate); } checkin.hide(); $('.j-end-date')[0].focus(); }).data('datepicker'); var checkout = $('.j-end-date').datepicker({ format: dateFormat, onRender: function(date) { return date.valueOf() <= checkin.date.valueOf() ? 'disabled' : ''; } }).on('changeDate', function(ev) { checkout.hide(); }).data('datepicker');

  • jQuery: How can I animate to a taller height with the height being added to the top of the element?

    - by Jannis
    Hi, I have a simple problem but I am not sure how to solve it. Basically I have some hidden content that, once expanded, requires a height of 99px. While collapsed the element holding it section#newsletter is set to be 65px in height. LIVE EXAMPLE: http://dev.supply.net.nz/asap-finance-static/ On the click of a#signup_form the section#newsletter is expanded to 99px using the following jQuery: $('#newsletter_form').hide(); // hide the initial form fields $('#form_signup').click(function(event) { event.preventDefault(); // stop click // animate $('section#newsletter').animate({height: 99}, 400, function() { $('#newsletter_form').show(300); }) }); All this works great except for the fact that this element sits in a sticky footer so its initial height is used to position it. Animating the height of this element causes scrollbars on the browser, because the 34px added are added to the bottom of the element, so my question: How can I add these 34px to the top of the element so the height expands upwards into the body not downwards? Thanks for reading, I look forward to your help and suggestions. Jannis

  • Issue with Facebook JS API, revokeAuthorization

    - by BBonifield
    I am trying to integrate FB connect into our user profile screen. Although, I'm having an issue with FB.ApiClient.revokeAuthorization. http://pastie.org/921942 The basic problem is that I revoke the auth at line 44 after the user clicks the disconnect button. After that, all subsequent API calls don't have a valid session to even check user status. I've tried wrapping blocks in a FB.Connect.forceSessionRefresh block, but then the code will never be called at all. I'm not sure what the proper workflow should be for this purpose. Right now it's basically... User arrives at profile NOT connected to the application. User clicks on the connect button. Once connected, DOM manipulation occurs to hide the connect button and add in a disconnect button. User clicks on the disconnect button. User's authorization to the application is revoked and (it seems) the API session to the FB server is invalidated. DOM manipulation occurs to hide the disconnect button and readd the connect button. User clicks on the connect button. Once connected, the FB.Connect.get_loggedInUser() don't return the actual user.

  • Assign a unique client ID to each <rich:dataTable /> row?

    - by Dolph Mathews
    I'm relatively new to working with the UI in Seam, so I'm hoping there is something simple I can replace the three instances of UNIQUE_ID with in the following example (such as #{object.uniqueId}). The goal is to have a <rich:dataTable /> wherein each row has the ability to show/hide a <rich:modalPanel /> with more details about the particular object instance. <rich:dataTable var="object" value="#{bean.myObject}"> <rich:column> <h:outputText value="#{object.summary}" /> </rich:column> <rich:column> <a onclick="Richfaces.showModalPanel('UNIQUE_ID');" href="#">Show Details in ModalPanel</a> <a4j:form> <rich:modalPanel id="UNIQUE_ID" > <a onclick="Richfaces.hideModalPanel('UNIQUE_ID');" href="#">Hide This ModalPanel</a> <h:outputText value="#{object.details}" /> </rich:modalPanel> </a4j:form> </rich:column> </rich:dataTable> If I only had one link/modalPanel pair, this would obviously be trivial, but I don't know what to do within the scope of the <rich:dataTable />'s iteration. Also, in case it complicates things further, the page will also contain many <rich:dataTable />'s, each implementing this behavior.
