I’m used to using PHPs foreach function to iterate through an array. I finally found support for this in javascript the other day. Here is an example of its use.
var myArr = new Array();
myArr[0] = "element 1";
myArr[1] = "element 2";
myArr[2] = "element 3";
myArr.forEach(yell);
function yell(element, index, array)
{
alert(index+' '+element);
}
This will alert each key in the array and its associated element. Obviously you can do a lot more with this.
