Regular Expressions in JavaScript

[ReadyToLearn]

Hello,

I'm horrible with regular expressions as was hoping that someone would be able to help me create the RegEx pattern I need to accomplish some basic data extraction.

I have a url in following format:

http://www.example.com/xxx/yyy/index.php?/zzz/aaa/###

I just need the last number (highlighted above). The number itself can be any number of digits long and it's always preceded by a backslash.

Does anyone know a right RegEx pattern to accomplish what I want?

Here:

<script type="text/javascript">
var site = "http://www.example.com/xxx/yyy/index.php?/zzz/aaa/###";


var site_arr = site.split("/");
alert(site_arr[site_arr.length-1]);  
</script>
