var str = "";
var regEx = /([0-9]+)/;
var match = regEx.exec(str)[0];

i.e. like this:

var str = '';
            var reg = new RegExp('(.*)Stories\/([0-9]+)\?(.*)','i');
            var val = str.replace(reg,'$2');

Or, you could just use string functions
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    <script type="text/javascript">
        function testFunction(str){
         alert(getStringBetweenLastSlashAndQuestionMark(str)+" should be 65789");
        function getStringBetweenLastSlashAndQuestionMark(str){
            return str.substring(str.lastIndexOf("/")+1,str.indexOf("?"));
<a href="#" onclick="javascript:testFunction(''); return false;">click</a>
