    How to Assign null value to parameter in this function
    <script type="text/javascript">
    $(document).ready(function(){
    function alpha_numeric(an) {
    var TCode = document.getElementById(an).value;
    for(var i=0; i<TCode.length; i++)
    {
    var char1 = TCode.charAt(i);
    var cc = char1.charCodeAt(0);
    if((cc>47 && cc<58) || (cc>64 && cc<91) || (cc>96 && cc<123) || (cc==32) || (cc==95))
    {
    }
    else
    {
    alert('Special character are not allowed\n\nPlease enter only alphanumeric and underscore');
    here i want to assign null value parameter or input field(#filcompname) but field name or id is not static it's dynamic or multiple field
    return false;
    }
    }
    }
    $('.wrapper .accountinfo .information li.inputs #filcompname').live('keyup',function(){
    var an = $(this).attr("id");
    alpha_numeric(an);
    });
    });
    </script>
