  • jQuery - Drag of elements in areas - then not draggable any more

    - by Tim
    Hello! I have three div areas. Creating an element, which is draggable() with jQuery UI, I can drag it all over the screen. Dropping it in a special area, then I can not drag it any more. I created a full working demo: http://jsbin.com/enusu4/2/ There you can create a draggable element which is placed into the left green area. Dragging it to the middle or right green area, I can not drag the element. I increment the zIndex of the elements, but it does not work. Does anyone can help me, what's wrong? Best Regards.

  • jquery animation - when do they finish?

    - by Naor
    I have two jquery animations one by other: books.animate({ left: left1 }, { duration: this.slideDuration, easing: this.easing, complete: complete }); laptops.animate({ left: left2 }, { duration: this.slideDuration, easing: this.easing, complete: complete }); I want the animations to run simultanusly so I use {queue: false}: books.animate({ left: left1 }, { duration: this.slideDuration, easing: this.easing, queue: false, complete: complete }); laptops.animate({ left: left2 }, { duration: this.slideDuration, easing: this.easing, queue: false, complete: complete }); But now the completed callback called twice! How can I know exactly when does the both animations are done?

  • jQuery - deferred versus promise

    - by fletchsod
    What is the difference between Deferred and Promise other than the jQuery versions? What should I use for my need? I only want to call the fooExecute(). I only need the fooStart() and fooEnd() to toggle the html div status for example. //I'm using jQuery v2.0.0 function fooStart() { /* Start Notification */ } function fooEnd() { /* End Notification */ } function fooExecute() { /* Execute the scripts */ } $('#button1').on('click', function() { var deferred1 = $.Deferred(); var promise1 = $.Promise(); deferred1.??? promise1.??? });

  • Rejoin branching using jQuery formwizard?

    - by Vinay
    jQuery formwizard (http://thecodemine.org/) allows you to branch a form wizard based on inputs. I am trying to figure out if it possible to rejoin the branches (and not just for the last step.) e.g. Based on the inputs to Step 1, I'd like to present the user with a different step 2. However, after step 2, the remaining steps (step 3, 4, 5, etc.) should all be the same. How can this be done? Thanks!

  • jQuery on/delegate correct syntax

    - by KryptoniteDove
    As the jQuery API is currently down, is anyone able to assist me with the below? I am ajax loading an unordered list into the web page and need to be able to attach hover and click events to the list items. <ul> <li class="option">Item 1</li> <li class="option">Item 1</li> <li class="option">Item 1</li> </ul> So far I have tried a few variations of the below jQuery code using .on for version 1.7+ $("ul").on("click", "li .option", function(){ alert($(this).text()); }); Can anyone point me in the right direction? I'm aware that .live has been depreciated and that .delegate has been superceeded so really only looking for a solution that will allow me to use .on. Thanks as always!

  • jquery - appended element not draggable

    - by kikkoman90
    Hello, So i have one div element that i append on my DOM with a click of a link. The problem is that i should be able to move that element around, but if i append it to my DOM i can't drag it at all. So is the live()-function solution? If it is, how should i use it? I kinda don't know how. Here's the minimalistic code: element to be appended (data.html): <div id="menu"> <p>random stuff here</p> </div> jquery: $("#menu").draggable(); $("#button").click(function(){ //custom function for exists() if ($("#menu").exists()){ $("#menu").remove(); } else { $.get("data.html", function(data){ $("body").append(data); }); } });

  • jQuery plugin to style objects

    - by Alex
    Hi. I've been looking at the various JavaScript UI libraries and am wondering if there's one that can add some styling to page elements. I'm currently adding rounded corners, shadows, borders, and gradients via my own CSS + hacks to get it working on IE. I'm using jQuery for a number of tasks and wondered if there's a plugin that can add these design flairs more easily to DIVs. Not that you want to go overboard with this stuff, but when you need to use it, you'd like to depend on cross-browser and tried-and-tested solutions. Thanks.

  • Developing with Fluid UI – The Fluid Home Page

    - by Dave Bain
    v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} The first place to start with Fluid UI is with the Fluid Home Page. Sometimes it’s referred to as the landing page, but it’s formally called the Fluid Home Page. It’s delivered with PeopleTools 8.54, and the nice thing about it is, it’s a component. That’s one thing you’ll discover with Fluid UI. Fluid UI is built int PeopleTools with Fluid UI. The Home Page is a component, the tiles or grouplets are group boxes, and the search and prompt pages are just pages. It makes it easy to find things, customize and brand the applications (and of course to see what’s going on) when you can open it in AppDesigner. To see what makes a component fluid, let’s start with the Fluid Home Page. It’s a component called PT_LANDINGPAGE. You can open it in AppDesigner and see what’s unique and different about Fluid UI. If you open the Component Properties dialog, you’ll see a new tab called Fluid On the Component Properties Fluid tab you’ll see the most important checkbox of all, Fluid Mode. That is the one flag that will tell PeopleSoft if the component is Fluid (responsive, dynamic layout) or classic (pixel perfect). Now that you know it’s a single flag, you know that a component can’t be both Fluid UI and Classic at the same time, it’s one or the other. There are some other interesting fields on this page. The Small Form Factor Optimized field tells us whether or not to display this on a small device (think smarphone). Header Toolbar Actions offer standard options that are set at the component level so you have complete control of the components header bar. You’ll notice that the PT_LANDINGPAGE has got some PostBuild PeopleCode. That’s to build the grouplets that are used to launch Fluid UI Pages (more about those later). Probably not a good idea to mess with that code! The next thing to look at is the Page Definition for the PT_LANDINGPAGE component. When you open the page PT_LANDINGPAGE it will look different than anything you’ve ever seen. You’re probably thinking “What’s up with all the group boxes”? That is where Fluid UI is so different. In classic PeopleSoft, you put a button, field, group, any control on a page and that’s where it shows up, no questions asked. With Fluid UI, everything is positioned relative to something else. That’s why there are so many containers (you know them as group boxes). They are UI objects that are used for dynamic positioning. The Fluid Home Page has some special behavior and special settings. The first is in the Web Profile Configuration settings (Main Menu->PeopleTools->Web Profile->Web Profile Configuration from the main menu). There are two checkboxes that control the behavior of Fluid UI. Disable Fluid Mode and Disable Fluid On Desktop. Disable Fluid Mode prevents any Fluid UI component from being run from this installation. This is a web profile setting for users that want to run later versions of PeopleTools but only want to run Classic PeopleSoft pages. The second setting, Disable Fluid On Desktop allows the Fluid UI to be run on mobile devices such as smartphones and tablets, but prevents Fluid UI from running on a desktop computer. Fluid UI settings are also make in My Personalizations (Main Menu->My Personalizations from the Main Menu), in the General Options section. In that section, each user has the choice to determine the home page for their desktop and for tablets. Now that you know the Fluid UI landing page is just a component, and the profile and personalization settings, you should be able to launch one. It’s pretty easy to add a menu using Structure and Content, just make sure the proper security is set up. You’ll have to run a Fluid UI supported browser in order to see it. Latest versions of Chrome, Firefox and IE will do. Check the certification page on MOS for all the details. When you open the first Fluid Landing Page, there’s not much there. Not to worry, we’ll get some content on it soon. Take a moment to navigate around and look at some of the header actions that were set up from the component properties. The home button takes you back to the classic system. You won’t see any notifications and the personalization doesn’t have any content to add. The NavBar icon on the top right has a lot of content, including a Navigator and Classic home. Spend some time looking through what’s available. Stay tuned for more. Next up is adding some content.

  • Non-Dom Element Event Binding with jQuery

    - by Rick Strahl
    Yesterday I had a short discussion with Dave Reed on Twitter regarding setting up fake ‘events’ on objects that are hookable. jQuery makes it real easy to bind events on DOM elements and with a little bit of extra work (that I didn’t know about) you can also set up binding to non-DOM element ‘event’ bindings. Assume for a second that you have a simple JavaScript object like this: var item = { sku: "wwhelp" , foo: function() { alert('orginal foo function'); } }; and you want to be notified when the foo function is called. You can use jQuery to bind the handler like this: $(item).bind("foo", function () { alert('foo Hook called'); } ); Binding alone won’t actually cause the handler to be triggered so when you call: item.foo(); you only get the ‘original’ message. In order to fire both the original handler and the bound event hook you have to use the .trigger() function: $(item).trigger("foo"); Now if you do the following complete sequence: var item = { sku: "wwhelp" , foo: function() { alert('orginal foo function'); } }; $(item).bind("foo", function () { alert('foo hook called'); } ); $(item).trigger("foo"); You’ll see the ‘hook’ message first followed by the ‘original’ message fired in succession. In other words, using this mechanism you can hook standard object functions and chain events to them in a way similar to the way you can do with DOM elements. The main difference is that the ‘event’ has to be explicitly triggered in order for this to happen rather than just calling the method directly. .trigger() relies on some internal logic that checks for event bindings on the object (attached via an expando property) which .trigger() searches for in its bound event list. Once the ‘event’ is found it’s called prior to execution of the original function. This is pretty useful as it allows you to create standard JavaScript objects that can act as event handlers and are effectively hookable without having to explicitly override event definitions with JavaScript function handlers. You get all the benefits of jQuery’s event methods including the ability to hook up multiple events to the same handler function and the ability to uniquely identify each specific event instance with post fix string names (ie. .bind("MyEvent.MyName") and .unbind("MyEvent.MyName") to bind MyEvent). Watch out for an .unbind() Bug Note that there appears to be a bug with .unbind() in jQuery that doesn’t reliably unbind an event and results in a elem.removeEventListener is not a function error. The following code demonstrates: var item = { sku: "wwhelp", foo: function () { alert('orginal foo function'); } }; $(item).bind("foo.first", function () { alert('foo hook called'); }); $(item).bind("foo.second", function () { alert('foo hook2 called'); }); $(item).trigger("foo"); setTimeout(function () { $(item).unbind("foo"); // $(item).unbind("foo.first"); // $(item).unbind("foo.second"); $(item).trigger("foo"); }, 3000); The setTimeout call delays the unbinding and is supposed to remove the event binding on the foo function. It fails both with the foo only value (both if assigned only as “foo” or “foo.first/second” as well as when removing both of the postfixed event handlers explicitly. Oddly the following that removes only one of the two handlers works: setTimeout(function () { //$(item).unbind("foo"); $(item).unbind("foo.first"); // $(item).unbind("foo.second"); $(item).trigger("foo"); }, 3000); this actually works which is weird as the code in unbind tries to unbind using a DOM method that doesn’t exist. <shrug> A partial workaround for unbinding all ‘foo’ events is the following: setTimeout(function () { $.event.special.foo = { teardown: function () { alert('teardown'); return true; } }; $(item).unbind("foo"); $(item).trigger("foo"); }, 3000); which is a bit cryptic to say the least but it seems to work more reliably. I can’t take credit for any of this – thanks to Dave Reed and Damien Edwards who pointed out some of these behaviors. I didn’t find any good descriptions of the process so thought it’d be good to write it down here. Hope some of you find this helpful.© Rick Strahl, West Wind Technologies, 2005-2010Posted in jQuery

  • JQuery + WCF + HTTP 404 Error

    - by hangar18
    HI All, I've searched high and low and finally decided to post a query here. I'm writing a very basic HTML page from which I'm trying to call a WCF service using jQuery and parse it using JSON.

My sample is based on this I've been trying to fix the code for sometime now so I'd like you to take a look and see if you can figure out what is it that I'm doing wrong here.

I'm gonna blog about this as soon as the issue is resolved for the benefit of other devs Thanks -Soni

  • Using JQuery to replace multiple instances of HTML on one page

    - by Kenneth B
    I've made a script which copies the alt attribute of an image and puts it into a <span>. It also formulates the information divided by a hyphen. It works like a charm, but only with one image. I would also like to wrap a <div> around the image to prevent unnecessary markup. Script snippets: HTML: <div id="hoejre"> <p> <span class="alignright"> <img src="tommy_stor.jpg" alt="Name - Title" width="162" height="219" /> <span></span> </span> </p> </div> jQuery: var alt = $("#hoejre p span img").attr("alt"); $('#hoejre p span span') .html("<strong>" + alt.replace("-", "</strong> <em>") + "</em>"); Output: <span class="alignright"> <img height="219" width="162" alt="Name - Title" src="tommy_stor.jpg"> <span> <strong>Name</strong><em>Title</em> </span> </span> How do you I repeat the effect on several images, with different information within?

  • jQuery Drag/Drop problem: mousemove Event not binding for some elements

    - by saturdayplace
    Using the latest jQuery/UI that are hosted at Google. I've got the following markup: <ul id="tree"> <li><a href="1/">One</a></li> <li><a href="2/">Two</a></li> </ul> And the following javascript: $(document).ready(function(){ // Droppable callbacks function dragOver(overEvent, ui_object) { $(this).mousemove(function(moveEvent){ console.log("moved over", this); }); } function drop_deactivate() { $(this).unbind(); } function drag_out() { $(this).unbind(); } // Actual dragging $("#treeContainer li").draggable({ revert: true, revertDuration: 0 }); // Actuall dropping $("a").droppable({ tolerance: "pointer", over: dragOver, deactivate: drop_deactivate, out: drag_out }); }); If I drag the first li down over the second, the mousemove function fires (and firebug logs the output). But if I drag the second li up over the first, the mousemove function doesn't fire. You can see this live at http://jsbin.com/ivala. Is there a reason for this? Should I be trapping the mousemove event in some other way? Edit: It appears as thought the mousemove() event isn't binding for earlier elements than the one currently being dragged (should be bound upon their mouseover).

  • What's the best practice to add default function to jQuery Dialog open/close events?

    - by BlueFox
    Hi All, I'm trying to define some default behaviours for my jQuery Dialogs like the following: (function($) { /** * Overriding default options **/ $.ui.dialog.defaults.bgiframe = true; $.ui.dialog.defaults.open = function() { if ($('.ui-widget-overlay').length == 0) return; if ($.browser.msie) { // scrollbar fix for IE $('html').css('overflow-y','hidden'); $('html').css('overflow-x','hidden'); } else { // disable scrollbar for other browsers $('body').css('overflow','hidden'); } }; $.ui.dialog.defaults.beforeclose = function(event, ui) { if ($('.ui-widget-overlay').length == 0) return; if ($.browser.msie) { // scrollbar fix for IE $('html').css('overflow-y','auto'); $('html').css('overflow-x','auto'); } else { // disable scrollbar for other browsers $('body').css('overflow','auto'); } }; })(jQuery); The above works when I have no custom open/beforeclose function specified when the dialog is created. So I'm wondering what is the best practice to add these functionality into all my dialogs, while preserving the ability to specify open/beforeclose functions.

  • Javascript conversion, from Prototype to jQuery

    - by moshimoshi
    Hi, I would like to update the following javascript code based on Prototype framework to jQuery framework: Event.observe(window, 'load', function() { $$('.piece').each(function(item) { new Draggable(item, { revert: true } ); }); $$('.cell').each(function(item) { Droppables.add(item, { accept: 'piece', onDrop: function(piece, cell) { cell.descendants().each(function(item) { item.remove(); } ); piece.remove(); piece.setStyle({ 'top': null, 'left': null }); new Draggable(piece, { revert: true }); cell.appendChild(piece); } }); }); }); The first part of the script is easy to convert: $(function() { $('.piece').draggable( { evert: true } ); $('.cell').droppable( { /* But here, it's more difficult. Right? ;) ... */ } }); }); Have you got an idea? Any part of code is welcome. Thanks a lot.

  • jQuery modal dialog on ajaxStart event

    - by bdl
    I'm trying to use a jQuery UI modal dialog as a loading indicator via the ajaxStart, ajaxStop / ajaxComplete events. When the page fires, an Ajax handler loads some data, and the modal dialog shows just fine. However, it never hides or closes the dialog when the Ajax event is complete. It's a very small bit of code from the local server that is returned, so the actual Ajax event is very quick. Here's my actual code for the modal div: $("#modalwindow").dialog({ modal: true, height: 50, width: 200, zIndex: 999, resizable: false, title: "Please wait..." }) .bind("ajaxStart", function(){ $(this).show(); }) .bind("ajaxStop", function(){ $(this).hide(); }); The Ajax event is just a plain vanilla $.ajax({}) GET method call. Based on some searching here and Google, I've tried altering the ajaxStop handler to use $("#modalwindow").close(), $("#modalwindow").destroy(), etc. (#modalwindow referred to here as to give explicit context). I've also tried using the standard $("#modalwindow").dialog({}).ajaxStart(... as well. Should I be binding the events to a different object? Or calling them from within the $.ajax() complete event? I should mention, I'm testing on the latest IE8, FF 3.6 and Chrome. All have the same / effect.

  • jQuery resizable() dynamic maxWidth option

    - by Vitaliy Isikov
    I have 3 columns that are resizable. When one is made wider, the one to it's left is made smaller. Essentially there are only 2 handles. Left col and Mid col. So when Mid col is made thinner, Right col expands accordingly. All three of them are contained with a 900px parent div, so the sum of all three is always 900. They have max and min widths set statically. My issue is that if you take the left handle and move it all the way to the right you're still able to use the right handle and expand the mid col past the edge of the parent div. I thought of a way to solve that issue by writing up a function that checks the widths of the columns and then subtracts left and right columns from the parent div width, I called it mWid. This leaves me with the number I want to set as the maxWidth for Mid col. Now the issue is that mWid is not gettings updated for here "maxWidth: mWid" Here is what the function for the right handle looks like: $(function() { $("#midResizable").resizable({ handles: 'e', containment: '#container', maxWidth: mWid, // gets set once, but doesn't update! WHY? minWidth: 195, resize: function(event, ui) { contWidth = $('#container').width() newWidth = $(this).width() leftWidth = $('#leftResizable').width() rightWidth = $('#rightResizable').width() $("#rightResizable").css("width", (contWidth-15)-(newWidth)-(leftWidth)+"px"); checkWid() } }); }); function checkWid() { rightWidth = $('#rightResizable').width() leftWidth = $('#leftResizable').width() contWidth = $('#container').width() mWid = (contWidth-15)-(rightWidth)-(leftWidth) }

When the question/response is read from the database, the response type determines which derived model is created and added to the collection. The main view it iterates through the collection and uses the 'Strongly Typed Partial Views' system of ASP.Net MVC to determine which view to render the correct type of response (radio button, drop down, or text box). I would like to change this process from a Html.BeginForm to Ajax.BeginForm. The problem is I don't have a clue as to how to implement the dynamic creation of the question/response in the JavaScript/jQuery world. Any thoughts and/or suggestions? Here is the current code to generate the dynamic form: @using (Html.BeginForm(new { mdsId = @Model.MdsId, sectionId = @Model.SectionId })) { <div class="SectionTitle"> <span>Section @Model.SectionName - @Model.SectionDescription</span> <span style="float: right">@Html.CheckBoxFor(x => x.ShowUnansweredQuestions) Show only unaswered questions</span> </div> @Html.HiddenFor(x => x.PrevSectionId) @Html.HiddenFor(x => x.NextSectionId) for (var i = 0; i < Model.answers.Count(); i++) { @Html.EditorFor(m => m.answers[i]); } }

  • How to update a Widget dynamically (Not waiting 30 min for onUpdate to be called)?

    - by Donal Rafferty
    I am currently learning about widgets in Android. I want to create a WIFI widget that will display the SSID, the RSSI (Signal) level. But I also want to be able to send it data from a service I am running that calculates the Quality of Sound over wifi. Here is what I have after some reading and a quick tutorial: public class WlanWidget extends AppWidgetProvider{ RemoteViews remoteViews; AppWidgetManager appWidgetManager; ComponentName thisWidget; WifiManager wifiManager; public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { Timer timer = new Timer(); timer.scheduleAtFixedRate(new WlanTimer(context, appWidgetManager), 1, 10000); } private class WlanTimer extends TimerTask{ RemoteViews remoteViews; AppWidgetManager appWidgetManager; ComponentName thisWidget; public WlanTimer(Context context, AppWidgetManager appWidgetManager) { this.appWidgetManager = appWidgetManager; remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget); thisWidget = new ComponentName(context, WlanWidget.class); wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE); } @Override public void run() { remoteViews.setTextViewText(R.id.widget_textview, wifiManager.getConnectionInfo().getSSID()); appWidgetManager.updateAppWidget(thisWidget, remoteViews); } } The above seems to work ok, it updates the SSID on the widget every 10 seconds. However what is the most efficent way to get the information from my service that will be already running to update periodically on my widget? Also is there a better approach to updating the the widget rather than using a timer and timertask? (Avoid polling) UPDATE As per Karan's suggestion I have added the following code in my Service: RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget); ComponentName thisWidget = new ComponentName( context, WlanWidget.class ); remoteViews.setTextViewText(R.id.widget_QCLevel, " " + qcPercentage); AppWidgetManager.getInstance( context ).updateAppWidget( thisWidget, remoteViews ); This gets run everytime the RSSI level changes but it still never updates the TextView on my widget, any ideas why?

  • Ruby on Rails + Jquery: Saving data from draggable lists

    - by sjsc
    Hello. I'm trying to save data to the MySQL database in Rails when the user drags items from different lists. I'm using the below Jquery script and HTML: <script> $(document).ready(function() { $("#draggable").draggable( { connectToSortable: 'ul#myList', helper:'clone' } ); $("#myList").sortable(); }); </script> HTML: <ul> <li id="draggable">Drag me to myList</li> </ul> <ul id="myList"> <li id="item-1">item 1</li> <li id="item-2">item 2</li> </ul> I know I probably have to use something like this: $.post({ url: 'lists/update', data: $('#myList').sortable("serialize") }); I've been Googling for the last few hours but can't seem to find how to save data between multiple lists using Rails. Any idea?

  • Determining selected state of jQuery Buttons

    - by lloydphillips
    I've got two radio buttons in a .net page which are being transformed to jQuery buttons a la http://jqueryui.com/demos/button/#radio When the page is loaded I have button 2 as checked. When clicking the buttons I'm firing the postback event. Problem is you can click on that button that is selected by default on the initial load i.e. Button 2, the postback is fired but the event handler isn't called in the .net code behind because the radio button is already classed as selected (and in normal circumstances wouldn't allow the postback to fire). To get around this I've added the e.PreventDefault() method BUT this is causing issues when Button 1 is clicked because before the click handler is called the button is set to selected. Therefore, in every case in the following code e.PreventDefault() is called: $(document).ready(function(){ $("[id*='rbPayable']").click(function(e){ if ($("[id*='rbPayable']").attr("checked")) e.preventDefault(); else setTimeout('__doPostBack(\'this.id\',\'\')', 0) }) $("[id*='rbReceivable']").click(function(e){ if ($("[id*='rbReceivable']").attr("checked")) e.preventDefault(); else setTimeout('__doPostBack(\'this.id\',\'\')', 0) }) }); What is the best way for me to load the page and effectively be able to do the following: 'If rbReceivable is checked then don't do anything otherwise do a postback.'
