Java Script Regular Expressions

[Dempsey.Jeff@gmail.com]

I am a wreck at regular expressions so I could use a little help.

Say I have a url that looks something like this.
http://test.com/test/test2/tabid/656/Default.aspx. I need to be able
to pull out only the word test2. I wont know that the word is going
to be test2 when I use the regular expressions so I need to find
everything between / and /tabid because that is the only thing that
will be the same no matter what.

<script type='text/javascript'>

var t = 'http://test.com/test/test2/tabid/656/Default.aspx';

t = t.replace(/.+\/([^\/]+)\/tabid\/.+/,'$1')

alert(t);


</script>

Untested:
/\/(.*?)\/tabid/

Less error-prone because not using the non-greedy subexpression and not
allowing the empty string:

/\/[^\/]+\/tabid/
