Q265 If I have two identically named submit buttons, but with different values, how can I tell which one was pressed?

<SCRIPT LANGUAGE="JavaScript"><!--
var button = 0;

function test(val) {
    button = val;
}

function check() {
    alert('Button ' + button + ' pressed');
}
//--></SCRIPT>

<FORM onSubmit="check()">
<INPUT TYPE="SUBMIT" NAME="xxxx" VALUE="Button 1" onClick="test('1')">
<INPUT TYPE="SUBMIT" NAME="xxxx" VALUE="Button 2" onClick="test('2')">
</FORM>
