Topic awaiting preservation: frame targeting

Aight all
Dont have a link to display this so I'm going to try and explain as best as.
I have a page with 2 <iframes>in it ...one left the other right
the left one contains a tree menu and i want the right one to be where pages come up in when a link is clicked
Heres a sample section of the tree menu I'm using to help further
var TREE_NODES = [
['First Item', null, null,
['Link1', 'link1.htm', '_top'],
['Link2', 'link2.htm', '_top'],
],
['Second Item', null, null,
['Link3', 'link3.htm', '_top'],
]
];
My problem is I cant target the right hand <iframe> when a link is clicked.
All the pages open up as a New Window on top of everything else...obviously because the target in the menu says _TOP that much I know.
But I've tried swapping _TOP for the target location as <iframe> ID, _main, newframe etc....nothing makes it target the <iframe>
Any help
Thanks

Just in case you need this ...heres the script for the tree menu

ok two suggestions for you:

1. give the right iframe a name and then use that as the target:

page 1 (main page):

<html>

<head>
<title>Page 1</title>
</head>

<body>

<iframe name="Iframe1" src="index2.htm"></iframe>

<iframe name="Iframe2" src="index3.htm"></iframe>

</body>

</html>

page 2 (iframe menu):

<html>

<head>
<title>open page</title>
</head>

<body>

<a target="Iframe2" href="mypage.htm">open page</a>

</body>

</html>

page 3 (targeted iframe):

<html>

<head>
<title>New Page 3</title>
</head>

<body>

</body>

</html>

Second suggestion:

2. Send links from menu to parent frame using js and target them to the right frame.

3th suggestion:
Post the code about the frames/links only that way it's easier to see what happens.

You don't need to stop at the parent element and then pass it down.


If you're iframes are named then you can change the location like so

top.iframe1.location.href = "wherever.html";
top.iframe2.location.href = "wherever2.html";

top will always be the top most frame. In this case the page with the two iframes in it. I like using top and working my way down because it is constant opposed to using parent which can be dynamic depending on the depth of your frames.




.:[ Never resist a perfect moment ]:.

Aight BITDAMAGED
Ok I tried the suggestions you gave me but when i clicked the links I still got the page i wanted to come up as a new window and not INSIDE the iframe on the page containing iframe 1 and 2.
Here's what I did to the tree menu

var TREE_NODES = [
['First Item', null, null,
['Link1', 'link1.htm', 'top.iframe2.location.href = "index.htm";'],
['Link2', 'link2.htm', '_top'], <<<<< This was the original script

]
];

Note: index.htm is the name for the page containing the 2 iframes i spoke of before.

When I tried SMONKEYS suggestion that system did target the Iframe but the tree menu didnt have any role in this action at all.
The link he gave in his example was in a seperate part of the page containing the menu tree so to speak and the tree menu for what it was worth was obsolete.

What I was hoping for was a script i could put in the tree menu js script itself releating to indevidual links like in this example below

var TREE_NODES = [
['First Item', null, null,
['Link1', 'a page.htm', 'SCRIPT HERE TO TARGET THE SECOND IFRAME ON THE SAME PAGE],
['Link2', 'another page.htm', '],'SCRIPT HERE TO TARGET THE SECOND IFRAME ON THE SAME PAGE

]
];

Hope this helps
Thanks guys
