Looking for a Javascript code coverage tool. Ideally, I'd be able to easily integrate with continuous builds. Looking for something that I can run cross-platform, but Windows only tools may be able to work. Does anybody have any good recommendations of tools to use or what tools to avoid? Note: I've already read through this question:...
I have two elements: <input a> <input b onclick="..."> When b is clicked, I want to access a and manipulate some of its data. A does not have a globally unique name, so document.getElementsByName is out. Looking into the event object, I thought event.target.parentNode would have some function like getElementsByName, but this does not ...
I am trying to apply styles to HTML tags dynamically by reading in the value of certain HTML attributes and applying a class name based on their values. For instance, if I have: <p height="30"> I want to apply a class="h30" to that paragraph so that I can style it in my style sheet. I can't find any information on getting the value of ...

I'm currently working on a JavaScript tool that, during the course of its execution, will ultimately traverse each node in the DOM. Because this has potential to be a very expensive task, I'd like to benchmark the performance of this script.

Hi! I want to insert some special characters at the caret inside textboxes using javscript on a button. How can this be done? The script needs to find the active textbox and insert the character at the caret in that textbox. The script also needs to work in IE and Firefox.

I want to link to bookmark on a page (mysite.com/mypage.htm#bookmark) AND visually highlight the item that was bookmarked (maybe having a red border). Naturally, there would be multiple items bookmarked. So that if someone clicked on #bookmark2 then that other area would be highlighted). I can see how to do that with .asp or .aspx b...
Like the Delicious submission bookmarklet, I'd like to have some standard Javascript I can use to submit any visited URL to a 3rd party site when that's possible by URL. Suggestions? For example, I've been using javascript:void(location.href="http://www.yacktrack.com/home?query="+encodeURI(location.href)) so far but wonder if there...
I've run into a problem where I make changes to a few JavaScript files that are referenced in an HTML file, but the browser doesn't see the changes. It holds onto the copy cached in the browser, even though the web server has a newer version. Not until I force the browser to clear the cache do I see the changes. Is this a web-server co...
So the SMEs at my current place of employment want to try and disable the back button for certain pages. We have a page where the user makes some selections and submits them to be processed. In some instances they have to enter a comment on another page. What the users have figured out is that they don't have to enter a comment if t...
Question I'm fairly familiar with many of the PHP frameworks out there, but I'm wondering which ones actually integrate AJAX functionality and which ones do it well? Ideally I'd love to find a framework that would allow me to avoid JavaScript alltogether (at least for typical/basic JavaScript functionality). Does such a thing exist? If...
This code is from Prototype.js. I've looked at probably 20 different tutorials, and I can't figure out why this is not working. The response I get is null. new Ajax.Request( /path/to/xml/file.xml, { method: "get", contentType: "application/xml", onSuccess: function( transport ) { alert( transport.responseXML ); } })...
I have an asp.net web page written in C#. Using some javascript I popup another .aspx page which has a few controls that are filled in and from which I create a small snippet of text.

WebKit/Safari supports the console object, which is similar to what Firebug does. But what exactly is supported? There is a console documentation for Firebug, but where can I find the console documentation for Safari/WebKit? ...
What's the simplest way to add a click event handler to a canvas element that will return the x and y coordinates of the click (relative to the canvas element)? No legacy browser compatibility required, Safari, Opera and Firefox will do. Update: Thanks @Brian, the following is working (in Opera and FF3 at least): canvas.addEventListen...
