• Showing same dfp ads in a single page web application

  - by mivaas19

  I have a single page web application which contains dfp ads. I have two dfp adunits that Iam firing and they are placed in between the content which is a list of articles for a particular category. When I click on another category,it just loads articles for different category(doesnt change the url in address bar) and triggers the same ads. So this is like triggering the ads on the same page. The ads dont show up the second time and this is because you cant use the same adunits on the same page. Since I cannot use the refresh function provided by dfp since my DOM is reconstructed everytime, is there any way I can do this?.

• jquery iterating through newly created elements

  - by jaeyun

  Hi All, I am trying to add new rows in my table, and save them into DB. First, I use .append() to append rows on the table: $("#tablename").append("<tr id='newRow'><td>newly added row</td></tr>"); The appending function works fine. My page displays the correct result. However, I am unable to select them with $("#newRow").each(function () { alert "it never reaches here!"; }); I am guessing it is because the elements are added after the DOM is loaded. Can anyone please tell me how I can iterate through all my newly added elements? Thank you.

• Jquery javascript - How can I let users 'undo' their modifications?

  - by Bill Zimmerman

  Hi, i have a basic jquery app that allows a user to edit and manipulate some lists on a page. What I would like to do is have a button 'restore original list' that the user can press to undo his modifications. What is the best way to do this? I was thinking of just copying the DOM from the list down, and pasting it in a hidden element someplace else on the page. Is this the best way to do this? I also noticed that jquery has a .data() function which I could use if I converted the data to an array and stored it this way. What are the advantages and disadvantages? Also, I'm open to any suggestions people have if there is some method I haven't thought of. Thanks for your help!

• Browser gets blocked, workers to the rescue?

  - by tb_selleo

  Hello, I use JavaScript for rendering 20 tables of 100 rows each. The data for each table is provided by controller as JSON. Each table is split into section that have "totals" and have some other JavaScript logic code. Some totals are outside of the table itself. As a result JavaScript blocks browser for a couple of seconds (especially in IE6) :( I was consideting to use http://code.google.com/p/jsworker/, however Google Gears Workers (I guess workers in general) will not allow me to make changes to DOM at the worker code, and also it seems to me that I can not use jQuery inside jsworker worker code. (Maybe I am wrong here?). This issue seems to be fundamental to the JavaScript coding practice, can you share with me your thoughts how to approach it?

• How do I move an element from an array to another array in javascript?

  - by TiansHUo

  My code is like var shapes1 = [ r.image("node.gif",190, 100, 47, 45)]; var shapes2 =[]; for (var i = 0, ii = shapes1.length; i < ii; i++) { shapes1[i].mousedown(function(e){ var temp=this.clone(); shapes1.push(temp); //now I want to remove "this" from shapes1 //and put it into shape2 //HOW?? isDrag=true; e.preventDefault(); }); } Maybe this is the wrong way to do it? I should be using a class instead, but isn't that for DOM items?

• Better Alternative to Telerik Draggable Panel ?

  - by user284523

  When putting a video in a Telerik Draggable Panel, when dragging the panel, on Firefox the video restart all over again because DOM is reconstructed. They don't seem to have an answer to this. Also we can't seem to be able to control the z-index as it doesn't take into account: when moving the panel over other telerik controls, the video slips under. So any other draggable panel that wouldn't have these annoyances ? Telerik doesn't seem to give any answer so we're afraid we're stuck and we cannot afford to wait longer. Currently think about using Yahoo UI.

• Why does $('#id') return true if id doesn't exist?

  - by David

  I always wondered why jQuery returns true if I'm trying to find elements by id selector that doesnt exist in the DOM structure. Like this: <div id="one">one</div> <script> console.log( !!$('#one') ) // prints true console.log( !!$('#two') ) // is also true! (empty jQuery object) console.log( !!document.getElementById('two') ) // prints false </script> I know I can use !!$('#two').length since length === 0 if the object is empty, but it seems logical to me that a selector would return the element if found, otherwise null (like the native document.getElementById does). F.ex, this logic can't be done in jQuery: var div = $('#two') || $('<div id="two"></div>'); Wouldnt it be more logical if the ID selector returned null if not found? anyone?

• Document to String?

  - by Nate

  I've been fiddling with this for over twenty minutes and my Google-foo is failing me. Let's say I have an XML Document created in Java (org.w3c.dom.Document): DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder docBuilder = docFactory.newDocumentBuilder(); Document document = docBuilder.newDocument(); Element rootElement = document.createElement("RootElement"); Element childElement = document.createElement("ChildElement"); childElement.appendChild(document.createTextNode("Child Text")); rootElement.appendChild(childElement); document.appendChild(rootElement); String documentConvertedToString = "?" // <---- How? How do I convert the document object into a text string?

• New to javascript, why is jQuery such a beast?

  - by gnucom

  Hey Everyone, I'm new to javascript (functional programming is okay for me, though) and I am wondering how jQuery got away with some of the design decisions they made. Is it just too much work to fix now or what? For instance, there seems use of strange symbols in strings when accessing elements in the DOM or weird function definitions for $, that are forcing me to check references every other time I want to get some basic data. Can someone point me to a learning source where I can learn all of these nuances of jQuery (jQuery's examples just don't cut it, they're too spread out)? Maybe someone has a super good reference site/pdf for jQuery? Thanks

• Easy way to replicate web page across machines?

  - by Mike_G

  I am trying to replicate a browser page to another browser on another machine. I basically want to reproduce a page exactly how it appears to a customer for viewing by the website owner. I have done this before using some impersonation trickery, but found that it would throw the session state out of wack when the site owner would switch customers. So I would like to stay away from cookie and authentication manipulation. Anybody done anything like that? Is there a way to easily transfer the DOM to a webservice? The tech/programming at my disposal are C#, javascript, WCF.

• Javascript Prototype Best Practice Event Handlers

  - by nahum

  Hi this question is more a consulting of best practice, Sometimes when I'm building a complete ajax application I usually add elements dynamically for example. When you'r adding a list of items, I do something like: var template = new Template("<li id='list#{id}'>#{value}</li>"); var arrayTemplate = []; arrayOfItem.each(function(item, index){ arrayTemplate.push(template.evaluate( id : index, value : item)) }); after this two options add the list via "update" or "insert" ----- $("elementToUpdate").update("<ul>" + arrayTemplate.join("") + "</ul">); the question is how can I add the event handler without repeat the process of read the array, this is because if you try add a Event before the update or insert you will get an Error because the element isn't still on the DOM. so what I'm doing by now is after insert or update: arrayOfItem.each(function(item, index){ $("list" + index).observe("click", function(){ alert("I see the world"); }) }); so the question is exist a better way to doing this??????

• Implement a calender with Ruby and Javascript in Rails

  - by samuel02

  I'm trying to implement a calendar with Ruby and Javascript in Rails. I'm using a calendar helper that creates a calendar with given year and month and events as parameters (<%= calendar(:year => 2012, :month => 4, :events => @events %>). I also have three buttons next, today and previous with which the user should be able to navigate the calendar with. I am also going to implement some js that makes it possible to select dates in the calendar. So what I would like to do is to insert the calendar in the DOM with javascript in order to generate a new calendar when the user clicks one of the buttons. That way I will be able to control the behavior of the buttons and add the select functionality. The problem is that I can't just insert my erb code in a javascript plus I'm not even sure it's the right way to go? Any suggestions are appreciated!

• Regular Expression to return the contents of a HTML tag received as a string of text

  - by Nathan Hernandez

  I have a string in my code that I receive that contains some html tags. It is not part of the HTML page being displayed so I cannot grab the html tag contents using the DOM (i.e. document.getElementById('tag id').firstChild.data); So, for example within the string of text would appear a tag like this: 12 My question is how would I use a regular expression to access the '12' numeric digit in this example? This quantity could be any number of digits (i.e. it is not always a double digit). I have tried some regular expressions, but always end up getting the full span tag returned along with the contents. I only want the '12' in the example above, not the surrounding tag. The id of the tags will always be 'myQty' in the string of text I receive. Thanks in advance for any help!

• What garbage collection algorithms do all 5 major browsers use?

  - by Martin Wittemann

  I am currently rethinking the object dispose handling of the qooxdoo JavaScript framework. Have a look at the following diagram (A is currently in scope): Let's say we want to delete B. Generally, we cut all reference between all objects. This means we cut connection 1 to 5 in the example. Is this really necessary? As far as I have read hear 1, browsers use the mark-and-sweep algorithm. In that case, we just need to cut reference 1 (connection to the scope) and 5 (connection to the DOM) which could be much faster. But can I be sure that all browsers use the mark-and-sweep algorithm or something similar? 1 http://stackoverflow.com/questions/864516/what-is-javascript-garbage-collection

• Preventing cross-site scripting in ASP.NET MVC - using jQuery or standard HtmlHelpers

  - by user313353

  I am building an ASP.NET MVC application that is AJAX-driven. For some reason I need to add some DOM elements on the fly when clicking a submit button. This is accomplished with jQuery.append(). One element inserted is a textarea, whose the data must be parse before submitting to ensure that no cross-site scripting can be done. We know that the Html.Encode() works great but must be declared outside a script tag. All I have done with jQuery is embedded within a script tag. 1) Is there a way to take advantage of the Html.Encode() within a script tag? 2) How can I accomplish this with jQuery? At worst I can use HttpUtility.HtmlEncode(), which is called on the server-side. Thanks for your help. Roland

• How can I make a Jeditable (jQuery) span activate editing on more than one event?

  - by JonathanHayward

  For the jQuery extension Jeditable, one of the parameters that can be specified is which DOM event will turn a div/span/... into a text input/textarea/... I would like to have more than one event serve as a trigger; that is, I would like either a click event or a contextmenu event to turn a span into an in-place edit area. Is there a graceful way to do this without forking Jeditable? --edit-- An example of code specifying the event is below. The parameter is optional, defaulting to a regular click. $(".edit_rightclick").editable("/ajax/save", { cancel: "Cancel", submit: "OK", tooltip: "Right click to edit.", event: "contextmenu", }); Calling twice, once for the regular click event with the event unspecified, and one for the contextmenu event (right-click if there are no switched mouse buttons or anything like that) does not seem to produce the intended effect of an element becoming editable in place on a click from either mouse button.

• Is it possible to do live events in YUI, similar to jQuery's live events?

  - by eculver

  It doesn't currently seem as though there is a way to do live events in YUI similar to jQuery: http://api.jquery.com/live/ It sure would be nice if something like: function handleClick(e) { // click! } YUI().use('node-base', function(Y) { Y.on("click", handleClick, ".foo"); }); caused handleClick to be fired when a node with the "foo" class was clicked on after being dynamically added to the DOM and sometime after the Y.on was evaluated. I feel like live events are one of jQuery's killer features that YUI lacks.

• Catching "NullPointerExceptions" in JavaScript

  - by Lenni

  I'm writing quite a bit of code in Prototype.js which returns null if a DOM-id wasn't found. $("someId").show(); If someId doesn't exist, a method will be called on null, which halts the entire program, in effect disabling all JS effects after the error. I could just check for null before executing such a statement, but this is getting tiring. I would like to catch an exception but I'm not sure which one its is. MDC lists the following ECMA Script error types: * Error * EvalError * RangeError * ReferenceError * SyntaxError * TypeError * URIError * DOMException * EventException * RangeException Also, do browsers have a unified way of dealing with a method call on null?

• Problem with dynamically added script element - attribute src is empty

  - by Stazh

  Hi there, I have a problem with dynamically added script element (using jQuery). Code for adding new script element to DOM is this: var pScript = document.createElement("script"); pScript.type = "text/javascript"; pScript.src = sFile; // Add element to the end of head element $("head").append(pScript); The script is added with no problem, and the code runs perfectly. But, the problem occurs when I try to find the newly added script. I use this code to iterate through all script elements: var bAdd = true; $("script").each(function() { if(this.src == sFile) bAdd = false; }); (I need this code to prevent adding script that is already loaded) Problem is that all other script elements have src attribute set, but the newly added (dynamically) has not... Any idea?

• javascript object access performance

  - by youdontmeanmuch

  In Javascript, when your getting a property of an object, is there a performance penalty to getting the whole object vs only getting a property of that object? Also Keep in mind I'm not talking about DOM access these are pure simple Javascript objects. For example: Is there some kind of performance difference between the following code: Assumed to be faster but not sure: var length = some.object[key].length; if(length === condition){ // Do something that doesnt need anything inside of some.object[key] } else{ var object = some.object[key]; // Do something that requires stuff inside of some.object[key] } I think this would be slower but not sure if it matters. var object = some.object[key]; if(object.length === condition){ // Do something that doesnt need anything inside of some.object[key] } else{ // Do something that requires stuff inside of some.object[key] }

• Print new line in the source-code with jQuery.

  - by Kucebe

  I have a simple function in jQuery that creates new elements in the DOM. the problem is in the html source code, it append every element in the same line, and it's very bad to read. function _loadNewElements(elements){ for(var i=0; i<elements.length; i++){ var fixedElement = $('<img />') var position = elements[i].position; var cssMap = { 'position': 'fixed', 'top': position.top + "px", 'left': position.left + "px" }; fixedElement.css(cssMap); fixedElement.addClass("fixedTag"); fixedElement.attr('alt', elements[i].text); fixedElement.attr('src', "elements/" + elements[i].id + ".png"); fixedElement.appendTo($('#board')); //i'd like to print something here like ("\n"); } } I tried document.write("\n") but in this context it doesn't work. Any solution?

• jQuery: selecting by class after class change by .addClass() or .attr()

  - by Sosh

  I have some jQuery code something like this: $(document).ready(function() { $("img.off").click(function() { alert('on'); $(this).attr('class', 'on'); }); $("img.on").click(function() { alert('off'); $(this).attr('class', 'off'); }); }); The selector works fine for images that have the class name defined in the original HTML document, however after manipulating the class name with jQuery, the img item will not respond to selectors using it's new class. In other words, running the above code, if you click an 'off' img, it will trigger the first function, and change the class to 'on'. However, clicking this image again does not trigger the second function (as I would have expected), but rather triggers the first again. It's as if the selector is reading the old DOM rather than the updated version. What am I doing wrong here? Firefox 3.6.3 - jQuery 1.4.2

• How to override JS function from a firefox extension?

  - by BruceBerry

  Hello, I am trying to intercept calls to document.write for all pages. Setting up the interception inside the page by injecting a script like function overrideDocWrite() { alert("Override called"); document.write = function(w) { return function(s) { alert("special dom"); w.call(this, wrapString(s)); }; }(document.write); alert("Override finished"); } is easy and works, but i would like my extension to setup the interception for each document object from inside the extension. I couldn't find a way to do this. I tried to listen for the "load" event and set up the interception there but it also fails. How do I hook calls to doc.write from an extension?

• [jquery] return the inserted element

Ex: var elem = $("body").append(""); $(elem).show(); but it seems that .append returns the whole jQuery object.. am i supposed to use an ID for the inserted element and always reference it by it?? i really hope that there is a smarter move here. I'm used to do it like that from Prototype..
