Hi experts!

I’ve been struggling with this issue for a while.

So I have a form like this:
http://www.w3schools.com/js/tryit.asp?filename=tryjs_form_validation

But the difference is that I have multiple buttons in my form… I will need to find out which button was pressed. How do I do this?

For example, below code has two buttons instead of one:  

<!DOCTYPE html>
<html>
<head>
<script>
function validateForm()
{
var x=document.forms["myForm"]["fname"].value;
if (x==null || x=="")
  {
  alert("First name must be filled out");
  return false;
  }
}
</script>
</head>

<body>
<form name="myForm" action="demo_form.asp" onsubmit="return validateForm()" method="post">
First name: <input type="text" name="fname">
<input name = "1" id="1" type="submit" value="Submit">
<input name = "2" id="2" type="submit" value="Submit">
</form>
</body>

</html> 

Open in new window


So how do I know which button was pressed? I need to find out so that I can do validations with Javascript for multiple buttons.

Thanks so much!

</html>

Thank you soooooooooooooooooooooooooo much! This little issue was driving me insane... I probably was missing one simple thing, and went looking for other complex solutions.
