I need a form with two buttons and ability to detect which button was
pressed. I got this code to work using a javascript global variable,
but I know there must be a better way using DOM. Any suggestions?

<html>
<head>
<script language="JavaScript" type="text/javascript">
// global var: which button I am pressing
var btnWhichButton;
//========================================================
// Check the input fields of the form
//========================================================
function chkMyForm() {
alert(btnWhichButton.value);
document.SubmitExpenseForm1.action="#";

        // If Delete Record
         if (btnWhichButton.value == "Delete Record")
        {
                document.SubmitExpenseForm1.DeleteRecordParm.value = 'Y' ;
                window.document.SubmitExpenseForm1.submit();
                   return;
        }

        // Otherwise do validation
           chkTextArea();
        document.SubmitExpenseForm1.DeleteRecordParm.value = 'N' ;
           window.document.SubmitExpenseForm1.submit();
}

//========================================================
// Check Text Area
//========================================================

function chkTextArea() {
// additional validation...
alert("Extra Validation done here")
}

</script>

</head>
<body>

<input type="submit" NAME="Submit" value="Submit Record"
onclick="btnWhichButton=this">

<input type="submit" NAME="DeleteRecord" value="Delete Record"
onclick="btnWhichButton=this">

        </form>

</BODY>
</HTML>
