Hi,

I have a web page. In that there is a toggle button to show or hide advanced search options. Below that there is a "IFrame A"(Table).

IFrame A conatins "IFrame B" (Table Contents). Based on the toggle switch status, i want to update "IFrame A" size without refreshing the "IFrame B".

Is it possible to do so ? Can you give me some example or point to some tutorial .

Thanks

Nest your frames using this format, this the same as with my last posted code:

document.getElementById("frameA").document.getElementById("frameB").document.getElementById("frameC").style.backgroundColor = "black";

You can target specific frames or frame element's using frame ids. Just apply different method's ( window.frames['frameA'].document.all.yourElem ) in your script to make it cross-platform.

Here's a more complex Demo.
First you will need to nest 2 documents using iframes. test.html (iframe)-->frameA.html (iframe)-->frameB.html and apply this codes in the test.html

   frameA.setAttribute( "style", "background-color : #365d95; width : 50%; height : 200px;" ); 
   } catch( e ) {
   frameA.style.width = "50%";
   frameA.style.backgroundColor = "#365d95";
