View Full Version : Best solution for browser back button on a page using iframe content?

02-01-2011, 03:05 PM
It's a well documented issue-
when you have a page that contains an iframe, and then navigate inside the iframe, hitting the browsers back button will only affect the contents of the iframe and not the entire page. I've been searching all over for solutions and cant find one that works for my current implementation.
Anyone have any suggestions?
Here is my code:

function ShowPage(frame)
frames[0].location = frame+'.html'

Buttons that change the contents of the iframe

<div id="thumb1"><a onmouseover="ShowPage('frame1')"onclick="ShowPage('frame1')" target="mainbox"></a></div>
<div id="thumb2"><a onmouseover="ShowPage('frame2')"onclick="ShowPage('frame2')" target="mainbox"></a></div>
<div id="thumb3"><a onmouseover="ShowPage('frame3')"onclick="ShowPage('frame3')" target="mainbox"></a></div>

and then the iframe itself

<iframe src="frame1.html" type="text/html" style="border-width:0; border-style:hidden;" transparency="true" name="mainbox" frameborder="0" scrolling="no" width="700" height="807">

What about using the native javascript object/property history ?
Try to see if the contentWindow reference object supports that property

thanks for the reply Kor-
How would i use your suggestion in my specific case?
To be clear- i want something that will basically override the browser back button's normal functionality (where 'normal' doesnt work 'normally' when an iframe is used anyway). I dont want to put a new back button on the page anywhere.

I'm not much of a js coder so you might need to spell it out for me- sorry in advance

I guess that is not possible. The browser's functionality is out of the client-side language's range.

well i might have mispoken-
I dont necessarily want to 'override' the back button, i just need a script that will load the iframe history states in a way that does not effect the history states of the main page.
If i go from page1 to page2, and then in page2 is an iframe that then loads iframe2, iframe3, iframe 4- hitting the back button would just take me back to iframe3 when i want it to go back to page1. Get what i mean?
