[Javascript] javascript and id's

[Flavio Gomes]

Having a form named* "myForm" and an input named "myInput":
 You can access it by "document.myForm.myInput" in the majority of the 
browsers.

* Yeah, by "named" I mean giving the "name" atribute a value.

<form name=myForm action=processStuff.html>
  <input type=text name=myInput value="Enter Text" />
  <input type=submit name=mySubmit value="Go" />
</form>

<script language="JavaScript">
  alert(document.myForm.myInput.value);

  document.myForm.myInput.onkeydown = function () {window.status=this.value}
</script>
