Cross-site XMLHttpRequest

If innerHTML is evil, then what's a better way change the text of a link?
I know innerHTML is supposedly evil, but I think it's the simplest way to change link text. For example: <a id="mylink" href="">click me</a> In JS you can change the text with: document.getElementById("mylink").innerHTML = new_text; And in Prototype/jQuery: $("mylink").innerHTML = new_text; works fine. Otherwise you have to rep...

Ideas on implementing Stack Overflow-style comments
I like the Stack Overflow comment UI a great deal and I'm looking into implementing the same thing on my own website. I looked at the code and it looks like the main tool here is WMD, with the JQuery TextArea Resizer playing a supporting role. WMD converts Markdown into HTML on the client side. That's pretty nice because it helps out w...
Get Element StyleSheet Style in JavaScript
I've been using John Resig's getStyle function from Pro JavaScript Techniques to get the style of elements: function getStyle(elem, name) { // J/S Pro Techniques p136 if (elem.style[name]) { return elem.style[name]; } else if (elem.currentStyle) { return elem.currentStyle[name]; } else if (document.de...
Implementing a self resetting XMLHttpRequest object

The idea is to maintain an open connection to a server which sends data when it is available (faking push). As soon as the XHR object completes, I need to spawn a new one to wait for any fresh data. Below is a snippet of code which outlines a...

JSON security best practices?
While researching the issue of JSON vs XML, I came across this question. Now one of the reasons to prefer JSON was listed as the ease of conversion in Javascript, namely with the eval().

Load JSON at runtime rather than dynamically via AJAX
Hi, I don't think this can be done "cleanly", but I'll ask anyway. I have a system which needs to get a JSON resource via a REST GET call in order to initialize. At the moment the system waits until the onLoad event and fires an ajax request to retrieve the resource, which I don't think is the best way to do it, as the resource is need...
jQuery UI dialog doesn't show in IE7
I've finally got the datepicker to work on my MVC demo site and also the dialog. I still have a few issues: the dialog doesn't show in IE7 so when I click a link where a confirm dialog is supposed to appear it just removes the row without showing the dialog. It works great in Firefox3 and Safari. Please try for yourself on my Demo sit...
How to walk the methods and their properties contained in a DLL?
Using preferably JScript, but VBscript will also do, how does one walk a DLL obtaining the properties and their attributes contained therein? Why? Because it would be good to ascertain the attributes of certain objects such as their datatypes at runtime rather than having to hard-code them before hand. An example of their use would be to...

JavaScript include declaration fails to find file
There has to be something utterly simple I'm overlooking here, but for the life of me I can't get a JavaScript file to include properly from my master page. My declaration in the <head> element looks normal enough: <head runat="server"> <title>Untitled Page</title> <script type="text/javascript" src="/_private/scripts/jquery-1....
