Hi,Timgerrlists
Seems that you haven't know clearly about the utility method $F.$F
is a convenience alias of Form.Element.getValue
.When you are going to use $F(elementid),you have to assure that the
element is a form element.
So,change your code properly,use a form tag to contain those
elements in the body tags.Just like,
<body>
<form id="form1">
<input type="text" id="userName" value="Joe Doe"><br/>
<input type="button" value="Test3" onclick="test3();"><br/>
<div id="uName">
What is your username?
</div>
</form>
</body>
BTW:In your script part,('uName').innerHTML should be $
('uName').innerHTML.
Also,there is a way to avoid using form tag,that is use $() instead of
$F().
