Question

Webpage with 3 Frames - Javascript communication between frames

Asked by: Jonesey007

Hi
Im working on a Webpage which has multiple frames. I have a Navigation frame which is hosting a JavaScript Tree written by Geir Landro. The tree is working fine and i have set the Target value as my content frame and it is displaying the pages as expected. I now would like to put hyper links in my content pages which works fine, unfortunatly if im using links in my content pages things get out of synch with the navigation bar.
The navigation tree has a method in the api which i can open a particular node via a method call. My question is how do i call a method from an external html page.
Eg in my navigation page i have an object called "Tree", i need to call "Tree.openTo(4,true)"
but i need to call it from one of my content pages which at this moment have no reference to Tree
Please can someone help, im sorry about my rambling description
Thank You

You should be able to use either top or parent, i.e:

top.Tree.openTo(4,true)

-or-

parent.Tree.openTo(4,true)

HTH,

Actually in the scheme of things, I forgot the nav page would be the holder of the script.

If this is the case you may need to rework your script and move it into the framesetting page.  Another posibility would be to tinker with the use of the page reloads and use the query string to pass the values of the pages you wish to load directly into the navigation page load event.

Thanks for the help Saige

Do you know of any simple examples that hold a script in the frame setting page that i can use as a guide?

 

by: weareitPosted on 2009-06-19 at 12:38:03ID: 24669312

Sorry about the delay in the response.  Without knowing the complexity of your script I can only use a simple demonstration.  Must warn you, this code is quite a few year old.
