Alert

This looks very much like a class assignment. You're supposed to work these problems out for yourself.

However, I'm bored at the moment, so …

You have this,

else {
   return true;
   alert("Only Numeric")
}

I didn't look at the decision part, so if there's a problem there, :shrug:

cheers,

Gary you go to top of the class

once the value will return by return true; it will not coming up again. we need to put that alert message before that return statement.

like this:

<script language="javascript">
 
function isNumberKey(evt)
    {
   var charCode = (evt.which) ? evt.which : event.keyCode;
    if (charCode > 31 && (charCode < 48    || charCode > 57))
{
alert("its fine now");
      return false;
}
else
{
alert("Only Numeric");
return true;
       }
}
 
</script>
