    Regular Expressions do that:
    Code:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"  "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <title>Untitled Document</title>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
    <meta http-equiv="Content-Style-Type" content="text/css">
    <meta http-equiv="Content-Script-Type" content="text/javascript">
    <script type="text/JavaScript">
    function valid(f) {
    if (!/^\d*$/.test(f.value)) {
    f.value = f.value.replace(/[^\d]/g,"");
    }
    } 
    </script>
    </head>
    <body>
    <input type="text" onkeyup="valid(this)" onblur="valid(this)">
    </body>
    </html>
