dear lazyweb,

exactly which circle of browser compatibility hell will I be doomed to if I make up my own DIV attributes in a (machine generated) HTML page for the benefit of the Javascript program inside? I mean, like, <div id="foo" xprev="bar" xnext="quux"> instead of having on-the-side associative arrays. (Does Javascript even have associative arrays? It must, but all the documentation I can find online fails to inform, and fails to inspire confidence in what little information it does provide.)

var assocarray = new Array();
assocarray['one'] = 1;
assocarray['two'] = 2;
alert(assocarray['two']);

Technically it's not working quite like an associative array, but it does the same thing. You could just say = new Object(), not that there's a whole lot of difference there in javascript. I think you can also do

var assocarray = {'one':1, 'two':2};
alert(assocarray['two']);

heh, I just tried it and var assocarray = new String(); will work too :)
(that would probably make that first person feel dirty too, but the way objects work is one of my favorite things about javascript)

I found the {'one':1, 'two':2} syntax this morning. It's great because it's exactly the same syntax that Python's built-in dictionary serializer uses. No tedious generator to write!

yay!
