I have some code doing this : var changes = document.getElementsByName(from); for (var c=0; c<changes.length; c++) { var ch = changes[c]; var current = new String(ch.innerHTML); etc. } This works fine in FF and Chrome but not in IE7. Presumably because getElementsByName isn't working in IE. What's the best workaround? ...

As these script resources grow in size it is advisable to minify the resources and keep your web pages as light as possible, of course. I know many developers who hand-feed their JavaScript resources into...

This guy says here's how to do it, but as of 2.0, this "feature" was disabled. I'm guessing there's some fancy javascript to employ to get around this limitation? ...

Specifically, I'm looking to mimic back button behavior with AJAX, and I don't want to attach #uglyhashes to every URL, which seems to be the standard practice of most solutions I've seen. (For what it's worth, I'm perfectly fine with a solution that does not work at all in IE. :P ) ...
I'm working on a kind of unique app which needs to generate images at specific resolutions according to the device they are displayed on. So the output is different on a regular Windows browser (96ppi), iPhone (163ppi), Android G1 (180ppi), and other devices. I'm wondering if there's a way to detect this automatically. My initial resear...

I'm creating a data entry app for some in-house stuff. My team needs to enter info about "items" which can have many "categories" and vice versa. I need a quick way to let them enter an arbitrary amount of categories. Here's my idea: On the item entry page, I'll have it so that initially there's one text input for "categories" and if...
