    more regex drama

    hello,

    apparently javascript doesn't allow this:
    Code:
    /(?<=\d).*/
    (I get an invalid group error)

    but all I want is to replace everything after the first number, not including the number. I just can't seem to get my head around regex. Any hints?

    Code:
    var str= "abc123xyz";
    str = str.replace(/(.*?\d+).*/i, "$1");  
    alert (str);

    thanks, Philip. It's not exactly what I had in mind, though - using your example, say I wanted to replace the xyz (although xyz changes) with def. I could do:
    Code:
    str = str.replace(/(.*?\d+).*/i, "$1")+"def"
    but isn't there some funkier way of doing it?

    Code:
    <script type = "text/javascript">
    
    var str= "abc123xyz";
    str = str.replace(/(.*?\d+).*/i, "$1def");  
    alert (str);
    
    </script>
    Not sure how to make this "funkier".
