I have a JavaScript method that I need to run on one of my pages, in particular, the onresize event. However, I don't see how I can set that event from my content page. I wish I could just put it on my master page, but I don't have the need for the method to be called on all pages that use that master page. Any help would be appreci...
I'm considering developing a website similar to stackoverflow, but the answers may also consist of drawings (schematics, in this case). I want to have an area in the answer form where they can make this schematic without requiring special plugins, etc. Are we to the point where SVG has or should have critical mass soon (1-2 years) s...

Is there an built-in function/method that can check if a given string is a valid URI or not in the Mozilla XUL toolkit. (I have looked for one but found none, but since this is my first time using XUL and it's documentation it could be that I just overlooked it. So I'm just making sure before I start writing my own IsValidURI function) ...
I see mainly 2 ways to set events in JavaScript: add event directly inside the tag like that: <a href="" onclick="doFoo()">do foo</a> Or set them by JavaScript like that: <a id="bar" href="">do bar</a> And add event in a <script> section inside <head> or in an external JavaScript file, like that if you're using prototypeJS: Ev...

After the suggestion to use a library for my ajax needs I am going to use one, the problem is that there are so many and I've no idea how to even begin telling them apart. Thus, can anybody A) Give a rundown of the differences or B) Point me (and others like me) somewhere that has such a list. Failing that plan C is to go with whichever...

I have a page with a Google Maps mashup that has pushpins that are color-coded by day (Monday, Tuesday, etc.) The IFrame containing the map is dynamically sized, so it gets resized when the browser window is resized. I'd like to put a legend in the corner of the map window that tells the user what each color means. The Google Maps API ...
After hours of debugging, it appears to me that in FireFox, the innerHTML of a DOM reflects what is actually in the markup, but in IE, the innerHTML reflects what's in the markup PLUS any changes made by the user or dynamically (i.e. via Javascript). Has anyone else found this to be true? Any interesting work-arounds to ensure both beha...
