  • Pulling .live() functionality out of jQuery

    - by Daniel
    I am writing a Firefox Add-On that currently is depending on jQuery for the following things: Selectors Animations A special .live("focus") hail-mary event-catching maneuver that happens to work with jQuery 1.4.2 (but not 1.4.4) jQuery isn't well suited for functioning inside XUL, and it's a miracle we've gotten this far with it. We're trying to remove the jQuery requirements, the first two are easy (animations are simple, and we can use .querySelector() instead of jQuery), but the .live has proven impossible to do on our own. I've tried reading the source code, but I haven't been able to piece it apart. What is the jQuery .live function doing? There's clearly a lot more going on than document.addEventListener("focus"/"focusin",function_to_pick_apart_events). What else is going on here?

  • jQuery Columnizer plugin only working correctly on window resize.

    - by rcon
    Hi, I'm using the jQuery Columnizer plugin, and I'm running into a weird problem. Using 3 columns, I columnize content from a hidden div into a target div. It distributes only one paragraph to each of the first two columns and then puts all the remaining paragraphs into the last column. But the strange thing is that it auto-corrects itself when the window is resized. I'm guessing it has something to do with the target div resizing since opening a firebug console window also causes it to auto-correct itself. Setting lastNeverTallest:true doesn't seem to do anything. $('#hidden-about').columnize({ columns: 3, target: '#interiors', lastNeverTallest: true, doneFunc: function() { $('#interiors').css('white-space', 'normal'); $('#interiors').fadeIn(200); } Thanks for any suggestions!

  • js code works for one variable(?), how to make it work for many?

    - by jerry87
    I have working code of js, it shows different div for selected option. <html> <head> <script src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> $(document).ready(function(){ $('#box1').hide(); $('#box2').hide(); $('#box3').hide(); $("#thechoices").change(function(){ $("#" + this.value).show().siblings().hide(); }); $("#thechoices").change(); }); </script> </head> <body> <select id="thechoices"> <option value="box1">Box 1</option> <option value="box2">Box 2</option> <option value="box3">Box 3</option> </select> <!-- the DIVs --> <div id="boxes"> <div id="box1"><p>Box 1 stuff...</p></div> <div id="box2"><p>Box 2 stuff...</p></div> <div id="box3"><p>Box 3 stuff...</p></div> </div> </body> </html> Please, I have no js experience, so I don't know how to make it work several times on one page for many "thechoices". Something like copy paste but more suitable than this: <script type="text/javascript"> $(document).ready(function(){ $('#box1').hide(); $('#box2').hide(); $('#box3').hide(); $('#box4').hide(); $('#box5').hide(); $('#box6').hide(); $("#thechoices").change(function(){ $("#" + this.value).show().siblings().hide(); }); $("#thechoices2").change(function(){ $("#" + this.value).show().siblings().hide(); }); $("#thechoices").change(); }); $("#thechoices2").change(); }); </script> </head> <body> <select id="thechoices"> <option value="box1">Box 1</option> <option value="box2">Box 2</option> <option value="box3">Box 3</option> </select> <!-- the DIVs --> <div id="boxes"> <div id="box1"><p>Box 1 stuff...</p></div> <div id="box2"><p>Box 2 stuff...</p></div> <div id="box3"><p>Box 3 stuff...</p></div> </div> <select id="thechoices2"> <option value="box4">1</option> <option value="box5">2</option> <option value="box6">3</option> </select> <!-- the DIVs --> <div id="boxes"> <div id="box4"><p>1 stuff...</p></div> <div id="box5"><p>2 stuff...</p></div> <div id="box6"><p>3 stuff...</p></div> </div> I know you can help me, it seems to be simple but I can't handle with this. How can I change my second code to work in the same way but not only for two selectors. I need it for many. Don't want to copy paste the same section like in my second code.

  • jQuery .noconflict with prototype not working in (you guessed it) IE.

    - by Kyle Sevenoaks
    On my new customer page, I have successfully implemented a jQuery show/hide toggle alongside a Prototype script using jQuery's .noconflict. (Thanks to all for answers!) But as the world of the net is, IE's not playing ball. {literal} <script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"> </script> <script type="text/javascript"> var $j = jQuery.noConflict(); $j(function() { $j("#button1").click(function() { $j("#show-hide").toggle("slow"); }); });? </script> {/literal} As you all must know by now, I'm just newly coming to all this jQuery stuff, so I have no idea what could cause it. Thanks for any help.

  • Prevent "jQuery( html )" from triggering the browser to request images and other referenced content

    - by Chris Dutrow
    Using jQuery to create new DOM elements from text. Example: jQuery('<div><img src="/some_image.gif"></img></div>'); When this statement is executed, it causes the browser to request the file 'some_img.gif' from the server. Is there a way to execute this statement so that the resulting jQuery object can be used from DOM traversal, but not actually cause the browser to hit the server with requests for images and other referenced content? Example: var jquery_elememnts = jQuery('<div><img class="a_class" src="/some_image.gif"></img></div>'); var img_class = jquery_elememnts.find('img').attr('class'); The only idea I have now is to use regex to remove all of the 'src' tags from image elements and other things that will trigger the browser requests before using jQuery to evaluate the HTML. How can jQuery be used to evaluate HTML without triggering the browser to make requests to the server for referenced content inside the evaluated HTML? Thanks!

  • Having trouble with Flash, Javascript and JQuery

    - by andypants
    I'm using JQuery with the JQuery flash plugin (http://jquery.lukelutman.com/plugins/flash/) and trying to send a JS call back to the flash, I keep running into "xxx is not a function" so apparently something is off. I'm new to JQuery and very new to this jquery flash plugin and just can't quite wrap my head around what I am doing wrong. Here's where I'm lading up the flash: <div id="tagimgback"> <script language="javascript"> $(document).ready(function(){ $('#tagflash').flash( { src: 'tagflash', width: 200, height: 200, flashvars: {theYear:'2010',theTagNumber:'123'} }, { version: 8 } ); }); </script> </div> And here's where I'm trying to call it: $("#tagflash").gotoNewFrame(theTagNumber); gotoNewFrame is an AS function within my flash. I know the function works as I've been able to test it prior to bringing jQuery into the mix.

  • Introducing jLight &ndash; Talking to the DOM using Silverlight and jQuery.

    - by Timmy Kokke
    Introduction With the recent news about Silverlight on the Windows Phone and all the great Out-Of-Browser features in the upcoming Silverlight 4 you almost forget Silverlight is a browser plugin. It most often runs in a web browser and often as a control. In many cases you need to communicate with the browser to get information about textboxes, events or details about the browser itself. To do this you can use JavaScript from Silverlight. Although Silverlight works the same on every browser, JavaScript does not and it won’t be long before problems arise. To overcome differences in browser I like to use jQuery. The only downside of doing this is that there’s a lot more code needed that you would normally use when you write jQuery in JavaScript. Lately, I had to catch changes is the browser scrollbar and act to the new position. I also had to move the scrollbar when the user dragged around in the Silverlight application. With jQuery it was peanuts to get and set the right attributes, but I found that I had to write a lot of code on Silverlight side.  With a few refactoring I had a separated out the plumbing into a new class and could call only a few methods on that to get the same thing done. The idea for jLight was born. jLight vs. jQuery The main purpose of jLight is to take the ease of use of jQuery and bring it into Silverlight for handling DOM interaction. For example, to change the text color of a DIV to red, in jQuery you would write: jQuery("div").css("color","red"); In jLight the same thing looks like so: jQuery.Select("div").Css("color","red");   Another example. To change the offset in of the last SPAN you could write this in jQuery : jQuery("span:last").offset({left : 10, top : 100});   In jLight this would do the same: jQuery.Select("span:last").Offset(new {left = 10, top = 100 });   Callbacks Nothing too special so far. To get the same thing done using the “normal” HtmlPage.Window.Eval, it wouldn’t require too much effort. But to wire up a handler for events from the browser it’s a whole different story. Normally you need to register ScriptMembers, ScriptableTypes or write some code in JavaScript. jLight takes care of the plumbing and provide you with an simple interface in the same way jQuery would. If you would like to handle the scroll event of the BODY of your html page, you’ll have to bind the event using jQuery and have a function call back to a registered function in Silverlight. In the example below I assume there’s a method “SomeMethod” and it is registered as a ScriptableObject as “RegisteredFromSilverlight” from Silverlight.   jQuery("body:first").scroll(function() { var sl = document.getElementbyId("SilverlightControl"); sl.content.RegisteredFromSilverlight.SomeMethod($(this)); });       Using jLight  in Silverlight the code would be even simpler. The registration of RegisteredFromSilverlight  as ScriptableObject can be omitted.  Besides that, you don’t have to write any JavaScript or evaluate strings with JavaScript.   jQuery.Select("body:first").scroll(SomeMethod);   Lambdas Using a lambda in Silverlight can make it even simpler.  Each is the jQuery equivalent of foreach in C#. It calls a function for every element found by jQuery. In this example all INPUT elements of the text type are selected. The FromObject method is used to create a jQueryObject from an object containing a ScriptObject. The Val method from jQuery is used to get the value of the INPUT elements.   jQuery.Select("input:text").Each((element, index) => { textBox1.Text += jQueryObject.FromObject(element).Val(); return null; });   Ajax One thing jQuery is often used for is making Ajax calls. Making calls to services to external services can be done from Silverlight, but as easy as using jQuery. As an example I would like to show how jLight does this. Below is the entire code behind. It searches my name on twitter and shows the result. This example can be found in the source of the project. The GetJson method passes a Silverlight JsonValue to a callback. This callback instantiates Twit objects and adds them to a ListBox called TwitList.   public partial class DemoPage2 : UserControl { public DemoPage2() { InitializeComponent(); jQuery.Load(); }   private void CallButton_Click(object sender, RoutedEventArgs e) { jQuery.GetJson("http://search.twitter.com/search.json?lang=en&q=sorskoot", Done); }   private void Done(JsonValue arg) { var tweets = new List<Twit>(); foreach (JsonObject result in arg["results"]) { tweets.Add(new Twit() { Text = (string)result["text"], Image = (string)result["profile_image_url"], User = (string)result["from_user"] } ); } TwitList.ItemsSource = tweets; } }   public class Twit { public string User { get; set; } public string Image { get; set; } public string Text { get; set; } }   Conclusion Although jLight is still in development it can be used already.There isn’t much documentation yet, but if you know jQuery jLight isn’t very hard to use.  If you would like to try it, please let me know what you think and report any problems you run in to. jLight can be found at:   http://jlight.codeplex.com

  • How necessary is it to learn JavaScript before jQuery?

    - by benhowdle89
    In my opinion, when I looked at JavaScript, it looked like not my cup of tea. When I came across jQuery, I loved it. I sat and watched Nettuts+ 15 days of jQuery screencasts, 1 year later and now I'm fairly confident I wouldn't develop a website without including jQuery's library. I have never felt this has held me back but my question is, will this come back and bite me in the ass one day, the fact that I didn't have a solid JavaScript foundation before jumping feet first into one of its best (if not the best) frameworks? Did anyone else take this approach?

  • Is using Javascript/JQuery for layout and style bad practice?

    - by Renesis
    Many, but not all, HTML layout problems can be solved with CSS alone. For those that can't, JQuery (on document load) has become very popular.* As a result of its ease, many developers are quick to use JQuery or Javascript for layout and style — even without understanding whether or not the problem can be solved with CSS alone. This is illustrated by responses to questions like this one. Is this bad practice? What are the arguments for/against? Should someone who sees this in practice attempt to persuade those developers otherwise? If so, what are the best responses to arguments in favor of JQuery saying it's "so easy"? * Example: Layouts that wish to use vertical layout flow of some kind often run into dead ends with CSS alone — this would include layouts similar to Pinterest, though I'm not sure that's actually impossible with CSS.

  • Could JQuery and similar tools be built into the browser install?

    - by Ozz
    After reading another question about JQuery and CDN's, is it feasible for tools like JQuery to "come with" the browser, thus reducing/eliminating the need for the first download from a CDN, or from your own host server. JQuery files specifically are pretty small, so you could easily have a number (all?) of the different versions as part of a browser install. Now fair enough, this would increase install footprint, download time for the browser itself. Then sites could check "local" first, before CDN (which then caches), before finally defaulting to downloading from the website server itself. If this is feasible, has it been done, and if not, why hasn't it be done?

  • Python dictionary key missing

    - by Greg K
    I thought I'd put together a quick script to consolidate the CSS rules I have distributed across multiple CSS files, then I can minify it. I'm new to Python but figured this would be a good exercise to try a new language. My main loop isn't parsing the CSS as I thought it would. I populate a list with selectors parsed from the CSS files to return the CSS rules in order. Later in the script, the list contains an element that is not found in the dictionary. for line in self.file.readlines(): if self.hasSelector(line): selector = self.getSelector(line) if selector not in self.order: self.order.append(selector) elif selector and self.hasProperty(line): # rules.setdefault(selector,[]).append(self.getProperty(line)) property = self.getProperty(line) properties = [] if selector not in rules else rules[selector] if property not in properties: properties.append(property) rules[selector] = properties # print "%s :: %s" % (selector, "".join(rules[selector])) return rules Error encountered: $ css-combine combined.css test1.css test2.css Traceback (most recent call last): File "css-combine", line 108, in <module> c.run(outfile, stylesheets) File "css-combine", line 64, in run [(selector, rules[selector]) for selector in parser.order], KeyError: 'p' Swap the inputs: $ css-combine combined.css test2.css test1.css Traceback (most recent call last): File "css-combine", line 108, in <module> c.run(outfile, stylesheets) File "css-combine", line 64, in run [(selector, rules[selector]) for selector in parser.order], KeyError: '#header_.title' I've done some quirky things in the code like sub spaces for underscores in dictionary key names in case it was an issue - maybe this is a benign precaution? Depending on the order of the inputs, a different key cannot be found in the dictionary.

  • CKEditor inside jQuery Dialog, how do I build it?

    - by Ben Dauphinee
    So, I'm working with CKEditor and jQuery, trying to build a pop-out editor. Below is what I have coded so far, and I can't seem to get it working the way I want it to. Basically, click the 'Edit' link, dialog box pops up, with the content to edit loaded into the CKEditor. Also, not required, but helpful if you can suggest how to do it. I can't seem to find out how to make the save button work in CKEditor (though I think the form will do it). Thanks in advance for any help. $(document).ready(function(){ var config = new Array(); config.height = "350px"; config.resize_enabled = false; config.tabSpaces = 4; config.toolbarCanCollapse = false; config.width = "700px"; config.toolbar_Full = [["Save","-","Cut","Copy","Paste","-","Undo","Redo","-","Bold","Italic", "-", "NumberedList","BulletedList","-","Link","Unlink","-","Image","Table"]]; $("a.opener").click(function(){ var editid = $(this).attr("href"); var editwin = \'<form><div id="header"><input type="text"></div><div id="content"><textarea id="content"></textarea></div></form>\'; var $dialog = $("<div>"+editwin+"</div>").dialog({ autoOpen: false, title: "Editor", height: 360, width: 710, buttons: { "Ok": function(){ var data = $(this).val(); } } }); //$(this).dialog("close"); $.getJSON("ajax/" + editid, function(data){ alert("datagrab"); $dialog.("textarea#content").html(data.content).ckeditor(config); alert("winset"); $dialog.dialog("open"); }); return false; }); });

  • How to pass a parameter to jQuery UI dialog event handler?

    - by bebraw
    I am currently trying to hook up jQuery UI dialog so that I may use it to create new items to my page and to modify ones existing already on the page. I managed in the former. I'm currently struggling in the latter problem, however. I just cannot find a nice way to pass the item to modify to the dialog. Here's some code to illustrate the issue better. Note especially the part marked with XXX. The {{}} parts are derived from Django template syntax: $(".exercise").click(function() { $.post("{{ request.path }}", { action: "create_dialog", exercise_name: $(this).text() }, function(data) { $("#modify_exercise").html(data.content); }, "json" ); $("#modify_exercise").dialog('open'); }); $("#modify_exercise").dialog({ autoOpen: false, resizable: false, modal: true, buttons: { '{% trans 'Modify' %}': function() { var $inputs = $('#modify_exercise :input'); var post_values = {}; $inputs.each(function() { post_values[this.name] = $(this).val(); }); post_values.action = 'validate_form'; //XXX: how to get the exercise name here? post_values.exercise_name = 'foobar'; $.post('{{ request.path }}', post_values, function(data) { if( data.status == 'invalid' ) { $('#modify_exercise').html(data.content); } else { location.reload(); } }, "json" ); } } }); Here's some markup to show how the code relates to the structure: <div id="modify_exercise" class="dialog" title="{% trans 'Modify exercise' %}"> </div> <ul> {% for exercise in exercises %} <li> <a class="exercise" href="#" title="{{ exercise.description }}"> {{ exercise.name }} </a> </li> {% endfor %} </ul>

  • Why unchecked jQuery UI radio button's label appears "checked" after refresh in FF and IE?

    - by Daj pan spokój
    I've got 2 radio buttons with labels: button A is checked by default in HTML (checked="checked"). They're then processed with jQuery UI Radio Button. When I check button B and refresh the page, B's label is displayed as checked (it has CSS ui-state-active class). And A's label is displayed as unchecked, even though it's A button that is actually checked. It happens in Firefox (3) and IE (8). In Chrome (5) it works fine - after refresh A's label is displayed as checked. <input class="ui-helper-hidden-accessible" id="show-all-hotels" name="radio" CHECKED="CHECKED" type="radio"> <label aria-disabled="false" role="button" class="ui-button ui-widget ui-state-default ui-button-text-only ui-corner-left" aria-pressed="false" for="show-all-hotels"> <span class="ui-button-text">All tours</span> </label> <input class="ui-helper-hidden-accessible" id="show-availability" name="radio" type="radio"> <label aria-disabled="false" role="button" aria-pressed="true" class="UI-STATE-ACTIVE ui-button ui-widget ui-state-default ui-button-text-only ui-corner-right" for="show-availability"> <span class="ui-button-text">Only available at</span> </label> Do You know why is it happening and how to make checked button label appear as checked in all browsers?

  • How to traverse table in Jquery and add a class?

    - by SWL
    I have a simple table of two rows. The first column is required, but the others are not; however, I would like them to be required in pairs. So if the user enters a value for Quantity3, then Size3 should also now be required. As a fiddle: http://jsfiddle.net/NaRts/7/ <tr> <td><input name="qty1[492]" class="qty required" type="text"></td> <td><input name="qty2[492]" class="qty" type="text"></td> <td><input name="qty3[492]" class="qty" type="text"></td> </tr><tr> <td><input name="size1[492]" type="text" class="size required" ></td> <td><input name="size2[492]" type="text" class="size" ></td> <td><input name="size3[492]" type="text" class="size" ></td> </tr> And the simple jQuery I have is: $('.qty').keyup(function() { var s = $(this).attr('name'); // = qty3[418] var qtyID = s.replace(/[^1-9\[\]]/g, ""); // = 3[418] var SizeID = "size" + qtyID; var $sizeInput = $(this).closest('tr').next().find(SizeID); $sizeInput.css('background-color', 'green'); $sizeInput.addClass('required'); //I tried this too but it didn't work //$(this).parent().find(SizeID).addClass('required'); });? ?

  • Any reason why my $.ajax success callback is not executed in Jquery?

    - by arma
    Hello, Today i discovered that my dev version of my website do not execute success callback, but all other javascript and jquery code is running good. Even my ajax request is performed and i can see response in firebug. $('#login').submit(function(){ var email = $('#l_email').val(); var pass = $('#l_pass').val(); if(email && pass != ''){ var str = decodeURIComponent($(this).serialize()); $.ajax({ type: "POST", url: "login.php", data: str, success: function(msg){ if(msg == 'OK'){ window.location = 'index.php' }else if (msg == 'NOT_OK'){ if(lang == 'lv'){ alert(message); }else if(lang == 'ru'){ alert(message); } }else if (msg == 'EMAIL_NOT_VALID'){ if(lang == 'lv'){ alert(message); }else if(lang == 'ru'){ alert(message); } } } }); }else{ alert('That form is empty.'); } return false; }); The thing is $.ajax part executes fine and i can see response in firebug "OK". But redirect is not happening and even if i replace that redirect with something like alert or console.log nothing comes up. What could cause this? It's really hard to track since firebug gives no errors.

  • JQuery: Live <a> tag partially working second time around.

    - by BPotocki
    I have the following jquery code: $("a[id*='Add_']").live('click', function() { //Get parentID to add to. var parentID = $(this).attr('id').substring(4); //Get div. var div = $("#CreateList"); //Ajax call to refresh "CreateList" div with new XML. div.load("/AddUnit?ParentID=" + parentID); }); Basically, contained within the div is a nested unordered list with several "Add_#" links. Clicking the links uses an ajax call to recreate the list with a new node. It clears all the add links, but they are added again by the ajax call. This is why I used the .live method so newly added "Add_#" links still have the binding. This works in most cases. If I click "Add_1", the div refreshes with the new info. If I then click "Add_2", it works again as expected. The problem I'm having happens when I click "Add_1", then the page refreshes (and creates a new "Add_1" link), then I click the re-rendered "Add_1" again. It's the same link, but it was refreshed during the ajax call. When I do that, the javascript function still gets called, but the .load method doesn't work. Any ideas why this might be happening? Thanks.

  • Getting JQuery UI Sortable to work on asp.net ListView items?

    - by Xaisoft
    I have the following ListView in which I am using the JQuery UI sortable function to be able to sort the items in the ListView. The problem is that I can't put a sortable class on the table in the ItemTemplate because it does not work, if I put a class="sortable" on the outer div, it works, but it allows me to sort everything within the ListView, I just want to be able to move sort the tables. Here is the markup <div> //Works here, but hr's become sortable too. <asp:ListView ID="lvwDocuments" runat="server"> <LayoutTemplate> <h3> Documents</h3> <asp:PlaceHolder ID="itemPlaceHolder" runat="server"> </asp:PlaceHolder> </LayoutTemplate> <ItemTemplate> <table class="sortable"> //Does not work Here <tr> <td> <p class="title"> <a runat="server" href='<%#Eval("url") %>'> <%#Eval("title") %></a></p> <br /> <p> <%#Eval("description") %></p> </td> </tr> </table> </ItemTemplate> <ItemSeparatorTemplate> <hr /> </ItemSeparatorTemplate> </div> Also, How can I preserve the sort order even after the page is refreshed.

  • Struts2 jQuery Plugin Autocompleter renders HTML with style attributes <== changing this?

    - by Tim
    I'm using the Struts2 jQuery plugin 2.1 and render an autocompleter in my JSP. Here's the code: <s:form id="search-form" action="search" theme="simple"> <s:url id="remoteurl" action="jsonlanguages"/> <div> <sj:autocompleter cssClass="bgstandardelement empty" id="languages" name="echo" href="%{remoteurl}" delay="50" value="Search..." /> <input type="submit" id="search-button" value="GO" /> </div> </s:form> No matter what theme I set the autocompleter-form to, the HTML rendered for the list I output is always an unordered list with a style element that I cannot override. It has the following stype-attribute: style='z-index: 1; top: 242px; left: 926px; display: none; width: 256px'; As I want another outfit for my list, this doesn't work. Putting in the following attribute has no effect: cssStyle="width:115px!important;" What can I do?

  • jQuery fade li elemet and cycle it when mouse hovered.

    - by Pennf0lio
    I'm trying to recreate an effect in jQuery, where an element(<li> <img>) will be cycled and has a fading effect when hovered. The '<li>' contains '<img>' (image screenshots). when the mouse is on top of element it will keep cycling all that are in '<ul>' with a fading effect. when the mouse is away it will stop cycling the list. I also want to add a pager where you can navigate to the list. My Existing Code: link text My Problem: The current code has some problem with the pagination, it added all images that can be seen on the code. instead of 1-8 only, it continued to add another 1-8 and another. Second problem is, It also start cycling and fading when the page loads. The cycling and fading should only be working when the mouse is on top of the element. I don't know if the 'Cycle Plugin' is really required on this approach, I wan't it to be minimal as much as possible. I just use 'Cycle Plugin' because it's a quick answer to my problem. The effect i'm trying to achieve: link text (WARNING: Contains some Pornography), Sorry of my example, I tried finding other alternative but no luck. Thanks and merry xmas!
