How to disable auto submit behavior when hitting e

Question

I want to hit enter key to go to p2.htm or p3.htm according to the input text that I was typing in. And I also want to hit submit1 button to alert('no1') manually.

It works in FireFox, but in IE6, when I hit enter key it will submit the submit button.

How can I make the thing right in IE 6 as it is in FireFox?

I use javascript and jQuery.

<input id="Text2"  type="text"  onkeyup="if(event.keyCode==13){go2();}" /> 
<input id="Text3"  type="text"  onkeyup="if(event.keyCode==13){go3();}" /> 

<input id="submit1"  type="submit" value="submit" onclick="alert('no1')" />

<script type="text/javascript">
    function go2()
    {
        window.location = "p2.htm";
    }
    function go3()
    {
        window.location = "p3.htm";
    }
</script>

The problem with the accepted solution is that normal submit buttons no longer work. You must script all the buttons.

<form onsubmit="return false"></form>

Here's a better solution that doesn't break non javascript submit buttons. This solution simply tells the browser to not do default behavior when a user hits the enter key on form inputs.

// prevent forms from auto submitting on all inputs
$(document).on("keydown", "input", function(e) {
  if (e.which==13) e.preventDefault();
});
