There are hashes in javascript:

You can use the Array object in this fashion:

myArray['Betty'] = 'Boop';
myArray['Fred'] = 'Flintstone';
myArray['Sandra'] = 'Dee';

Iteration by:

for (var i in
myArray)  app.alert(i); // do something here

OR:


http://developer.irt.org/script/518.htm

<script language="JavaScript"><!--

a = new Array();

a['test1'] = 'test 1 value';
a['test2'] = 'test 2 value';
a['test3'] = 'test 3 value';
a['test4'] = 'test 4 value';
a['test5'] = 'test 5 value';

function joinHash(what,separator) {
    var output = '';

	for (var i in a)
	output += a[i] + separator;

	return output.substring(0,output.length-1);
}

alert(joinHash(a,'/'));
//--></script>
