  • Javascript image change causes embeded UserControls to flicker

    - by Sam Barham
    I have a n html page being displayed in IE. It has some buttons made up of images with mouseover/mouseout events on them in JavaScript, and a bunch of embedded .Net UserControls. When the mouseover/mouseout events fire, I change the images src to something else (simple rollover effect). The problem is that the UserControls often (but not always) flicker when this happens. To be clear, the images don't flicker, and the rest of the page doesn't flicker, just the embedded controls. This page is local, not coming from a server or anything. So, any ideas? More information : I've noticed that highlighting text does it too...

  • Searching for Nodes with Specific Text using the Prototype Javascript Framework

    - by Alan Storm
    Does the Prototype Javascript library have a selector that's equivalent to jQuery's :contains()? If not, what would what be "The Prototype Way" to selector/filter-down a list of elements that contains a particular string. For example, using the following $$('#some_div dd a') I may get back an array of 50 or so links. I only want the links that contain the work 'home'. In jQuery I'd do this jQuery('#some_div dd a:contains('home')'); Is it possible to do something similar using Prototype? If not, is there an elegant way to filter out the array of 50 elements that gets returned.

  • Tabbed javascript widget for a Rails app

    - by neilc
    A user registers on our Rails app and they're given javascript to embed a widget in their website. The widget has a tabbed interface, like the JQuery tabs http://stilbuero.de/jquery/tabs_3/. iFrames have been tested, but the widget form factor and cross-domain policy negates the use of iframes. The widget is very dynamic and will often update the DOM with new content - and because of cross-domain policy, it looks as though JSONP is necessary. I understand that 'widget.js.erb' needs to create the widget layout, reference a stylesheet, render the tabs, etc - but once a tab is clicked, how does the widget request the content from the Rails app and render it in the DOM?

  • Object comparison in JavaScript

    - by spankmaster79
    What is the best way to compare Objects in JavaScript? Example: var user1 = {name : "nerd", org: "dev"}; var user2 = {name : "nerd", org: "dev"}; var eq = user1 == user2; alert(eq); // gives false I know that "Two objects are equal if they refer to the exact same Object", but is there a way to check it another way?? Using this way works for me.....but is it the only possibility? var eq = Object.toJSON(user1) == Object.toJSON(user2); alert(eq); // gives true

  • Javascript Regular expression to enforce 2 digits after decimal points

    - by Manas Saha
    I need to validate a text box where users are supposed to enter numeric values with 2 decimal places. I am validating the text in client side javascript. The validation will pass only if the number has precisely 2 decimal places, and there is at least 1 digit before the decimal point. (could be zero) the number before the decimal point can be 0, but can not be multiple zeroes. like 00 or 000 The number before the decimal point can not begin with more than 1 zero. Example of Passed validation: 0.01 0.12 111.23 1234.56 012345.67 123.00 0.00 Example of failed validation .12 1.1 0.0 00.00 1234. 1234.567 1234 00123.45 abcd.12 12a4.56 1234.5A I have tried with [0-9][.][0-9][0-9]$ But it is allowing alphabets before decimal point. like 12a4.56 Can anyone please fix the expression? thanks a lot in advance.

  • Why does having a transitional doctype, cause my javascript to fail in WebKit and Opera Browsers

    - by morgenmuffel
    Hi all I am trying to get a mouseover script to work, when there is no doctype set the script works fine in all browsers I test, but the site looks like a dogs breakfast However When i set the doctype to transitional (it has to be this doctype) Firefox and IE8 (&compat mode) work fine But Opera and the webkit browsers can only display the popup above the page fold, so if you scroll down the page and go over an image the popup appears above the visible page. And I can't figure out why, there are a couple of instances of document.all in the code, but my attempts to replace these have broken the code, besides the fact it works in Firefox and not Opera makes me think that document.all is not the issue Any help would be appreciated, even just telling me why a doctype would effect Javascript would be a help. Here is the site without a doctype As I can't post 2 links, being a new user and all, follow the link above and change and change the url from noodle3 to noodle to see the site with a doctype

  • Unicode and URI encoding, decoding and escaping in JavaScript

    - by apphacker
    If you look at this table here, it has a list of escape sequences for Unicode characters that don't actually work for me. For example for "%96", which should be a –, I get an error when trying decode: decodeURIComponent("%96"); URIError: URI malformed If I attempt to encode "–" I actually get: encodeURIComponent("–"); "%E2%80%93" I searched through the internet and I saw this page, which mentions using escape and unescape with decodeURIComponent and encodeURIComponent respectively. This doesn't seem to help because %96 doesn't show up as "–" no matter what I try and this of course wouldn't work: decodeURIComponent(escape("%96)); "%96" Not very helpful. How can I get "%96" to be a "–" with JavaScript (without hardcoding a map for every single possible unicode character I may run into)?

  • Javascript Hex String to Image

    - by Gunnar Hoffman
    Hello everyone. I'll cut right to the chase. Right now I am developing a web based application. It has a PHP REST based architecture that serves up XML documents. On many of these documents attributes are hex encoded picture strings. On the client side jQuery AJAX fetches an XML document with a picture in it. I need to display said picture in some <img> tags. However my knowledge on such methods is lacking so here I am asking for help. Goal: JavaScript String variable in hex or base64 HTML displayed image. Cross browser is required, or a hack for the ones that do not support it is fine. Thanks, Gunnar

  • javascript "this" points to Window object again

    - by terrani
    Hello, I asked a question on http://stackoverflow.com/questions/2719643/javascript-this-points-to-window-object regarding "this" points to Window object. here is source code var archive = function(){} archive.prototype.action = { test: function(callback){ callback(); }, test2: function(){ console.log(this); } } var oArchive = new archive(); oArchive.action.test(oArchive.action.test2); Tim Down wrote "but that function is then called using callback(), which means it is not called as a method and hence this is the global object". What are differences between calling a function by its actual name and callback() as shown on the source code? How does console.log(this) in test2 points to Window when it is inside archive.action???

  • Cannot call external javascript function from SITE.MASTER

    - by WOPR
    I have a Site.Master in my ASP.NET project which defines a HEAD section as follows <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title id="MasterTitle">MyApp</title> <link rel="icon" href="Content/icon.ico" type="image/x-icon" /> <link href="Content/mycss.css" rel="stylesheet" type="text/css" /> <script src="Content/mycode.js" type="text/javascript"></script> </head> In the mycode.js file, I have a function called GetSels(); function GetSels() { //do stuff } If the GetSels function is defined in Site.Master, GetSels is callable. If it's in mycode.js, it's not. Every code example I've see seems to says this should work. What am I doing wrong?

  • Call JavaScript function from Silverlight 4.0 application

    - by Raha
    I am trying to call a function from a Silverlight application. It should be a very simple task to do but so far I am not getting the result that I am looking for. This is my Silverlight code: private void button2_Click(object sender, RoutedEventArgs e) { HtmlPage.Window.Invoke("SayHello", new string[] { "Salut!" }); } And this is the JavaScript code : function SayHello(theid) { alert(eval(theid)); var divStatusDiv = document.getElementById("divStatus"); divStatusDiv.style.backgroundColor = "Red"; } The alert message always show "undefined" but when I press "OK" the colour of that DIV gets changed to Red as it should be. Why am I getting "Undefined" all the time ?

  • Clean Microsoft Word Pasted Text using JavaScript

    - by OneNerd
    I am using a 'contenteditable' div and enabling PASTE. It is amazing the amount of markup code that gets pasted in from a clipboard copy from Microsoft Word. I am battling this, and have gotten about 1/2 way there using Prototypes' stripTags() function (which unfortunately does not seem to enable me to keep some tags). However, even after that, I wind up with a mind-blowing amount of unneeded markup code. So my question is, is there some function (using JavaScript), or approach I can use that will clean up the majority of this unneeded markup? Thanks -

  • Only the last run in a for loop in Javascript works

    - by Mengfei Murphy
    Here is a for loop written by Javascript. It is trying to apply queries for websql. for (var i = 0; i < 10; i++){ db.transaction(function (tx){ tx.executeSql('INSERT INTO ProjSetsT (ProjID) VALUES (?);', [i]); }); } The attempt is obvious, I tried to add values "0, 1, 2, ... 9" into column ProjID in table ProjSetsT. It does not work. I only got the last element, i.e. "9" inserted, but not the first eight numbers. Is there any syntax mistakes?

  • Get entire text of document as a string using javascript

    - by Tom Dignan
    I am developing a firefox extension and ideally would be able to get the whole darn DOM as a string.. forget any data structure. I just want what I see in "view source" in a buffer. I have been checking out javascript references and HTMLDocument etc. with no avail. Ideally I would be able to write to this buffer as well (seems possible i.e. document.writeLn()) I wish there was a document.read()? Am I just a js noob?

  • try-catch in JavaScript : how to get stack trace or line number of the original error

    - by Greg Bala
    When using TRY-CATCH in JavaScript, how to get the line number of the line that caused the error? On many browsers, the below code will work great and I will get the stack trace that points to the actual line that throw the exception. However, some browsers do not have "e.stack". Iphone's safari is one example. Is there someway to get the line number that will work for all browsers? try { // lots of code here var i = v.WillGenerateError; // how to get this line number in catch?? // lots of code here } catch (e) { alert (e.stack) // this will not work on iPhone, for example } Many thanks!

  • Ways to access a JavaScript Object's Property in IE6

    - by aaronrussell
    I have a JavaScript object with some properties. Lets say: var haystack = { foo: {value: "fooooo"}, bar: {value: "baaaaa"} }; Now, I want to access one of those properties, but I don't know which one. Luckily, this variable does: var needle = "foo"; In modern browsers I seem to be able to do the following and it works: haystack[needle].value; # returns "fooooo" But in IE6 it throws a wobbly, haystack[...] is null or not an object. Is there a way to achieve what I'm trying to achieve in IE6? If so, how so?

  • Parse text/html part of email source using Javascript

    Using javascript, I need to parse the Content-Type text/html portion of an email message and extract just the HTML part.

How do I do this? NOTE: I'm OK with a hacky regex. I don't expect this to be bulletproof.

  • Is the JavaScript RegExp implicit method deprecated?

    - by Eric
    So everyone knows what I mean by "implicit methods"? They're like those default properties from the Windows COM days of yore, where you could type something like val = obj(arguments) and it would be interpreted as val = obj.defaultMethod(arguments) I just found out JavaScript has the same thing: the default method of a RegExp object appears to be 'exec', as in /(\w{4})/('yip jump man')[1] ==> jump This even works when the RegExp object is assigned to a variable, and even when it's created with the RegExp constructor, instead of /.../, which is good news to us fans of referential transparency. Where is this documented, and/or is it deprecated?

  • Compressing plaintext in JavaScript?

    - by AgileMeansDoAsLittleAsPossible
    I have a simple Notepad-like web application I'm making for fun. When you save a document, the contents of a <textarea> are sent to the server via Ajax and persisted in a database. Let's just say for shits and giggles that we need to compress the contents of the <textarea> before sending it because we're on a 2800 baud modem. Are there JavaScript libraries to do this? How well does plain text compress in the first place?
