Using : document.forms[0]
<a href="#" onclick="alert(document.forms[0].name); return false;">Click</a>

Open in new window


To get the first one (or the only one) : document.getElementsByTagName("form")[0]
<a href="#" onclick="alert(document.getElementsByTagName('form')[0].name); return false;">Click</a>

Open in new window

...it's not quite that simple, try this instead:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>
<title>http://www.experts-exchange.com/Programming/Languages/Scripting/JavaScript/Q_26850984.html</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<script type="text/javascript"> 

jQuery(document).ready(function() {

  $(".click-me").click( click );

});

function click() {
  var formName = $(this).closest("form").attr("name");
  alert( formName );
}

</script>

</head>
<body>

<form name="form-one">
  <a href="#" class="click-me">Click</a>
</form>

<form name="form-two">
  <a href="#" class="click-me">Click</a>
</form>


</body>
</html>

one final question on this post if youd be so kind ...
You showed me how to get form name or id - which is what I need some of the time.
Other times I need the form object - ya know like if you had a form named myForm then what I mean is document.myForm will give you the parent form object.

how can i get that?
thanks ...

Just remove the .attr()

var formName = $(this).closest("form").attr("name");
var formObject = $(this).closest("form");
