Can anyone tell me why below javascript functions are not calling while clicking the button or submitting the form.

I am not getting wht is the wrong with this code. Please help

 <script type="text/javascript"> function confrm() { alert("check1"); if(confirm("Are you going to submit this form?")==true) { return true; } else { return false; } } function checkfrm() { var selcteddate=document.newrequest.sel.value; var sdate=new Date(selcteddate); alert("check 2"); if(document.newrequest.server.value=="select") { alert("Select server"); return false; } else { return true; } } </script> <form id="newrequest" name="newrequest" method=post action="cgi-bin/newrequest.cgi" onsubmit="return checkfrm();"> <td colspan=2> <input type="submit" id="submit" name="submit" value="Submit" onclick="return confrm();" /> </td>

You can do it without return. Try this :

<script type="text/javascript">
    function confrm(){
        alert("check1");
        if(confirm("Are you going to submit this form?")==true) {               
            document.getElementById("newrequest").submit();
        }else{
            return false;
        }
    }
    </script>
<form id="newrequest" name="newrequest" method="post" action="cgi-bin/newrequest.cgi" onsubmit="checkfrm();">
<td colspan=2>
<input value="Submit" type="input" onclick="confrm();" />
</td>
