a question about dynamically form

[chang nanny]

Hello,
I have a dynamically form.
there's a text field and a submit button on each form.
as I enter text and press the submit button.
I would like to use javascript to check which form's text field with value.
How should i do?
thank you.

Basic Idea is below....

<script>
  function CheckSubmit(){
    if(document.FormName.ElementName.value.length > 0)return true;
    else return false;
  }
</script>
<form name="blah" onsubmit="return CheckSubmit()">
