var str = "http://msn.com/news/Stories/65789?id=12&type=software";
var regEx = /([0-9]+)/;
var match = regEx.exec(str)[0];

i.e. like this:



var str = 'http://msn.com/news/Stories/65789?id=12&type=software';
            
            var reg = new RegExp('(.*)Stories\/([0-9]+)\?(.*)','i');
            
            var val = str.replace(reg,'$2');
            
            alert(val);

<html>
<head>

    <script type="text/javascript">
        <!--
        function testFunction(str){
         alert(getStringBetweenLastSlashAndQuestionMark(str)+" should be 65789");
        }
        function getStringBetweenLastSlashAndQuestionMark(str){
            return str.substring(str.lastIndexOf("/")+1,str.indexOf("?"));
        }
                -->
    </script>
</head>
<body>
<a href="#" onclick="javascript:testFunction('http://msn.com/news/Stories/65789?id=12&type=software'); return false;">click</a>
</body>
