Traversing this tree

My biggest problem with DOM is getting to the elemnts on my page. Consider this structure;

Code:

<body>
    <table id="header"><tr><th></th></tr></table><br>
    <div id="btnBar">
        <table id="btntbl">
        	<tr><form id="tblTree" >
        		<th align="left" width="30%"></th>
    		<th align="left" width="30%"></th>
        		<th width="40%></th>
        	</tr></form>
        </table>
    </div>
    <Div id="DBStruct" >
    	<table id="tblList">
		<form id="tblColForm" >
			<input type=>
			<input type=>
			<input type=>
			<input type=>
		</form>
    	</table>
    </div>
    <iframe id="displayframe" name="displayframe">
         getIt.asp gets loaded here via javascript and contains this form
         <form name="dataEdit" id="dataEdit"  >
         <table id=""displayTable"" >
          <input id="thisOne" type="text" Value="" />
          </table>
          </form>
    </iframe>
</body>

I am trying to get to the fields on the form inside the iframe. I have tried this code but it wont execute the second alert.

Code:

function DoButton(which){
	alert("Doing button");
	alert(document.getElementById("dataEdit").name); 
}

I have cut all the garbbage out so you can see thiis clearly. So how would you get the value or place the value of the field "thisOne"?

Thanks, I hope someone sees this in this forum. I just thought it was more appropriate to the DOM forum.

document.frames[0].document.getElementById('dataEdit')

Is what you are looking for I think.

or more correctly:

top.frames['displayframe'].document.getElementById('dataEdit')

Thought my preference would be:

top.frames['displayframe'].document.forms['dataEdit']

For better cross-browser support

Thanks for your reply.

I hope I get a grip on the Parent/child node business here soon. Then maybe I wont have to ask bonehead questions. I keep looking at MS DOM documentation and after a couple of minutes I have to avert my eyes before they start bleeding.

I did find a nice tutorial that is a little more friendly on another web site (brainjar) so after reading that I may be able to work a little cleaner.

Thanks again.
