Javascript experts?

How the hell would I pass an associative array to a javascript function?

Shitty example:

<a onclick="test(arr['item']='Item Name', arr['price']='4.95');">click</a>

function test(arr)
{
alert(arr['item'] + arr['price']);
}

I don't know of a syntax that will let you do it that way, maybe just pass it in as a string of key and value pairs and have your function build the array from them.

why not do it like this instead

http://nation-x.com/test.html

<script type="text/javascript">
var arr = new Object();

function testIt() {
	for (var i in arr) {
		alert('arr[\''+i+'\'] is ' + arr[i])
	}
}
</script>

If you click <a href="#" onClick="arr.item='Item Name'; arr.price='4.95';testIt(); return false;">this link</a> this script is executed:</p>

You're the man now dog! Thanks!

Fuck, if I run this more than once on a page then old arguments are still passed through, unless I re-define them, then it's all good, but if I'm not using one of them on the 2nd time it will still be there from the first one. I tried clearing everything each time the function is run but it still persists. Maybe I need to clear the object each time or something? Haven't tried that yet I gotta run somewhere real quick..

<a onclick="test({name:'Item Name', price:4.95});">click</a>

function test(item)
{
    alert(item.name + ': $' + item.price.toFixed(2));
}

ooo that is neat, takes care of the persistent vars problem too, thanks dudes. The help here is better than any programming forum would do
