  • JavaScript using toString on a Function object to read text content

    - by mseeley
    Calling toString() on the function below returns different strings across browsers. I understand this is because ECMA-262 15.3.4.2 leaves wiggle room for each vendor. Chrome returns the comments in addition to all syntax. Sadly Firefox 3.6 omits the comments. Based on Firefox's behavior I haven't tested IE, Opera, or Safari. function foo() { /* comment */ var bar = true; } Specifically, I am attempting to embed meta data within a specially formatted comment block within a function. Later the return value of the functions toString() method would be parsed and values returned as an object. I've been unable to locate compatibility tables or alternatives to toString(). Does the community have any ideas? Btw, pre-processing JS files isn't an option. :( Thanks a lot. :)

  • Need a Javascript Expert, IE slow script

    - by Aaron Carlino
    I have a jQuery plugin running on my site that is executing very, very slowly in IE7/8 to the point that it throws a slow script warning to the user. It doesn't happen in any other browser, and I can't figure out what might be going on. If you go to this page: http://dev.xeetic.org/projects You'll see that there are 16 results on each page, and each one has a "flip" behavior attached, using the jQuery plugin "quickflip." Attaching this behavior is very slow in IE. If I reduce the result set to 8 or 4 per page, it's faster, but still very bogged down. I have contacted the author of the script with no success. I am willing to pay for a solution, if I'm allowed to offer such a thing on this site. Very desperate. Please help!

  • Javascript 'class' and singleton problems

    - by Kucebe
    I have a singleton object that use another object (not singleton), to require some info to server: var singleton = (function(){ /*_private properties*/ var myRequestManager = new RequestManager(params, //callbacks function(){ previewRender(response); }, function(){ previewError(); } ); /*_public methods*/ return{ /*make a request*/ previewRequest: function(request){ myRequestManager.require(request); //err:myRequestManager.require is not a func }, previewRender: function(response){ //do something }, previewError: function(){ //manage error } }; }()); This is the 'class' that make the request to the server function RequestManager(params, success, error){ //create an ajax manager this.param = params; this._success = success; //callbacks this._error = error; } RequestManager.prototype = { require: function(text){ //make an ajax request }, otherFunc: function(){ //do other things } } The problem is that i can't call myRequestManager.require from inside singleton object. Firebug consolle says: "myRequestManager.require is not a function", but i don't understand where the problem is. Is there a better solution for implement this situation?

    I declare a variable with the var word inside a function that handles Ajax requests, then later on in the function I have another function that should change the value of the variable but - my problem - it fails.

Here's similiar code I use: function sendRuest(someargums) { /* some code */ var the_variable; /* some code */ //here's that other function request.onreadystatechange = function() { if (request.readyState == 4) { switch (request.status) { case 200: //here the variable should be changed the_variable = request.responseXML; /* a lot of code */ //somewhere here the function closes } return the_variable; } var data = sendRequest(someargums); //and trying to read the data I get the undefined value

  • Javascript Alert Return value / Event

    - by Chris
    Hey, The question is pretty simple, but i'm not the big AJAX/JS coder, so I have no clue if it's possible. Is there any way that I can check whether or not an alert() was executed on a remote site? Like if I inputted an alert("Welcome to this site"); through a get variable, is there any way to check if it that alert() was actually executed in the browser? And not necessarily through AJAX/JS.

    - by Anil Namde
    I have table cell which has class "cellActive". Which has following defination .cellActive{background:"#DDDDDD"} Now i am trying to read the background color property for the cell and it comes null/"". var bgColor = cell.style.backgroundColor; // returning "" Is that something mistake on my part of its by behavior. If CSS class is assigning CSS to element can't we read its value in JS ? Does this mean that if we are not assigning property directly to the element we cant get it if in case its inheriting it ?

  • Javascript - remove part of cookie with a split('|') like array

    - by MgS
    I'm abit stuck. I'm using jQuery. I have a cookie which has the value such as : 1,something|2,somethingg|1,something We are treating it as [0] as id and [1] as name. I need to remove ONE where the id == '1' for example, this will leave the cookie like this: 1,something|2,somethingg How do I go about this, it will probally be in a loop, but not sure how to remove one of them. I have this so far: function removeItem(id){ var cookieName = 'myCookie'; var cookie = $.cookie(cookieName); if(cookie){ var cookie = cookie.split('|'); $(cookie).each(function(index){ var thisCookieData = this.split(','); if(thisCookieData[0] == id ){ } }); }

  • Javascript function question

    - by Raj
    I searched but couldn't find an answer to this seemingly easy question, so... Suppose I have a loop in which I need to set callbacks. My callback function looks like this: function callback(var1) { // code } Now my loop is something like this: for( //condition) { var x = something_different_each_time; document.getElementById('foo').addEventListener('click', function() { callback(x); }, false); } Now it looks like even if the loop runs n times, the anonymous function is compiled only once -- and hence every invocation of callback is called with the same argument (even though x varies in the loop every time). I must be missing something here.. any help is greatly appreciated! :)

  • Trouble adding event listeners via JavaScript

    - by Jack Roscoe
    Currently I have a function which loops to create multiple HTML objects. Each time an object is created, I want to add an onClick function listener to that object so that I can trigger a function when each one is clicked. What's the best way to do this? Here's the code which creates my objects: RenderMultipleChoice:function() { this.c = paper.rect(this.x, this.y, this.shapeWidth, this.shapeHeight); }

  • Escaping and unescaping a string with single and double quotes in Javascript

    - by Reina
    I have a search box that a user can search for any string including single AND double quotes, once they have searched, the backend is passing the keyword back to me so I can put it back in the box. I don't know what the string is so I can't escape quotes myself, below is an example: var keyword = "hello"; $("#selectionkeywords").val(); The issue I am having is that if the user enters "hello" the keyword becomes ""hello"" and I get this error: missing ) after argument list [Break On This Error] jQuery("#selectionkeywords").val(""hello""); The user could also enter single quotes so that rules it out as well. I tried using escape unescape but I still have the same issue e.g. escape(""hello"") I could get the value in an unescaped format e.g. "hello" but I don't know what to do with it, escape doesn't work on it I end up with this %26%23034%3Bhello%26%23034%3B So I'm pretty much stuck at the moment as I can't do anything to the string, any ideas?

  • Javascript to add cdata section on the fly?

    - by Chris G.
    I'm having trouble with special characters that exist in an xml node attribute. To combat this, I'm trying to render the attributes as child nodes and, where necessary, using cdata sections to get around the special characters. The problem is, I can't seem to get the cdata section appended to the node correctly. I'm iterating over the source xml node's attributes and creating new nodes. If the attribute.name = "description" I want to put the attribute.text() in a cdata section and append the new node. That's where I jump the track. // newXMLData is the new xml document that I've created in memory for (var ctr =0;ctr< this.attributes.length;ctr++){ // iterate over the attributes if( this.attributes[ctr].name =="Description"){ // if the attribute name is "Description" add a CDATA section var thisNodeName = this.attributes[ctr].name; newXMLDataNode.append("<"+thisNodeName +"></"+ thisNodeName +">" ); var cdata = newXMLData.createCDATASection('test'); // here's where it breaks. } else { // It's not "Description" so just append the new node. newXMLDataNode.append("<"+ this.attributes[ctr].name +">" + $(this.attributes[ctr]).text() + "</"+ this.attributes[ctr].name +">" ); } } Any ideas? Is there another way to add a cdata section? Here's a sample snippet of the source... <row pSiteID="4" pSiteTile="Test Site Name " pSiteURL="http://www.cnn.com" ID="1" Description="<div>blah blah blah since June 2007.&amp;nbsp; T<br>&amp;nbsp;<br>blah blah blah blah&amp;nbsp; </div>" CreatedDate="2010-09-20 14:46:18" Comments="Comments example.&#10;" > here's what I'm trying to create... <Site> <PSITEID>4</PSITEID> <PSITETILE>Test Site Name</PSITETILE> <PSITEURL>http://www.cnn.com</PSITEURL> <ID>1</ID> <DESCRIPTION><![CDATA[<div>blah blah blah since June 2007.&amp;nbsp; T<br>&amp;nbsp;<br>blah blah blah blah&amp;nbsp; </div ]]></DESCRIPTION> <CREATEDDATE>2010-09-20 14:46:18</CREATEDDATE> <COMMENTS><![CDATA[ Comments example.&#10;]]></COMMENTS> </Site>

  • javascript window.close, once again

    - by John Kjøller
    Im sorry if I havent done my research properly, - but couldnt find the answer I needed, so here goes: From my main page I open a new window using mainPlayer = window.open(); This window stays open until user clicks on a mainPlayer.close(); event. (or simply x closes the window) However, the idea is to make it possible to let the player keep playing, while browsing around the rest of the pages. But as soon as the user leaves the page that opened the mainPlayer window, the reference to the mainPlayer window seem to be lost. How do I, from the site's other pages, check if the mainPlayer window is open and close it on a click event? Thx John

  • Javascript, IE, Strings, and Performance problems

    - by Infinity
    Hey guys, So we have this product, and it's really slow in IE. We've already applied a lot of the practices advised by the IE guys themselves (like this, and this), and try to sacrifice clean code for performance in the critical parts like DOM manipulation. However, as you can see in this IE profiler screenshot.. Just "String" is the biggest offender. Almost 750ms of exclusive time. Does this mean IE is spending 750ms just instantiating Strings? I also read this stuff on the Opera dev blog: A build script can remove whitespace, comments, replace strings with Array lookups (to avoid MSIE creating a string object for every single instance of a string — even in conditions) But no more info regarding this. Anyone can clarify? It seems like IE has to create a full String instance every time you have " " in your code, which could explain this, but I don't know what the array lookup optimization would look like. BTW- we don't really do much of string concatenation anywhere in the code. The library we use is MooTools 1.2.4 Any suggestions will be appreciated! Thx

  • How to get array keys in Javascript?

    - by DisgruntledGoat
    I have an array created with this code: var widthRange = new Array(); widthRange[46] = { sel:46, min:0, max:52 }; widthRange[66] = { sel:66, min:52, max:70 }; widthRange[90] = { sel:90, min:70, max:94 }; I want to get each of the values 46, 66, 90 in a loop. I tried for (var key in widthRange) but this gives me a whole bunch of extra properties (I assume they are functions on the object). I can't use a regular for loop since the values are not sequential.
