Regular Expressions problem

**linewirefx** · 09-23-2010 06:50 PM

This problem has made me gone insane and cant seem to fix it...although I am a complete noob when it comes to regular expressions.

I basically want to match the numbers at the end of the following string:

Code:

<input type="checkbox" id="4_23_check" value="off" style="float:left;line-height:24;" />23

which would return "23"

I know this is probably super simple, I tried doing

Code:

var re = "/\/>(.*?)/";
var newStrings = theBigStringAbove.match(re);

But couldn't get er' jump started. Any assistance would be awesome!

I'm not exactly sure this is what you are trying to do, but here goes ...

Code:

<html>
<head>
<title>regExp Match</title>
</head>
<body>

<script type="text/javascript">
// From: http://www.webdeveloper.com/forum/showthread.php?t=236106

var str =  '<input type="checkbox" id="4_23_check"'
    str += ' value="off" style="float:left;line-height:24;" />23';

var re = /\d\d$/;
var newStrings = str.match(re);
alert(str+'\n'+re+'\n'+newStrings);

</script>
</body>
</html>

Thanks for the reply. It is part of what I need.
For that particular string it works but I will also have various other values after the <input ... />, example:
"Rob's Clothes"
or
United States 3
etc.
So I pretty much need everything after that.

Another shot ...

Code:

<html>
<head>
<title>regExp Match</title>
</head>
<body>

<script type="text/javascript">
// From: http://www.webdeveloper.com/forum/showthread.php?t=236106

var re = />.*$/;

var str =  '<input type="checkbox" id="4_23_check"'
    str += ' value="off" style="float:left;line-height:24;" />23';

var newStrings = str.match(re);
alert(str+'\n'+re+'\n'+newStrings[0].substring(1));

    str = "< other stuff>Robin's Clothes";
    newStrings = str.match(re);
alert(str+'\n'+re+'\n'+newStrings[0].substring(1));

    str = "< other stuff> United States 3";
    newStrings = str.match(re);
alert(str+'\n'+re+'\n'+newStrings[0].substring(1));

</script>
</body>
</html>
