The simplest way to traverse arrays in js is to use for and then use the length of arr.length as the maximum value of for. Let's take a look at some useful examples
Example: for (){} Traverse the array
<script type="text/javascript">
<!--
var arr = new Array(13.5,3,4,5,6);
for(var i=0;i<arr.length;i++){
arr[i] = arr[i]/2.0;
}
alert(arr);
//-->
</script>Example: for in loop traverse the array
<html>
<body>
<script type="text/javascript">
var x
var mycars = new Array()
mycars[0] = "Saab"
mycars[1] = "Volvo"
mycars[2] = "BMW"
for (x in mycars)
{
document.write(mycars[x] + "<br />")
}
</script>
</body>
