the page contains a list from which the user can choose and each selected value loads new data to the page.
One of these data items is a url provided to an iframe.
I use jQuery BBQ: Back Button & Query Library to simulate the browser-back behavior.
All works well besides the fact that when i click the back button for the first time the iframe goes back to its previous location and then I need to click back again to make the page go back.
Is there a way to disable the iframe's back behavior?
I've found the answer to my problem guess it could be useful for others out there.
The problem was with the way i assigned new URLs to my Iframe, i used Jquery so it looked something like that:
When assigning the URL in that manner it adds a new entry to the browser's list of visited URLs to go back to.
That wasn't the desired behavior, so after some googling i found that you can assign a new URL to an Iframe object without adding it to the 'back-list', it looks like that:
var frame = $('#myIFrame'); frame.contentWindow.location.replace(newUrl);
This way my back button behave exactly as expected.
btw, i got my answer from here.
Hope this was helpful to you as it was to me.
The accepted answer does not seem to work if you try to set a cross-domain URL for the IFrame. As a workaround, I detached the IFrame from the DOM before setting the
src (using jQuery).
// remove IFrame from DOM before setting source, // to prevent adding entries to browser history var newUrl = 'http://www.example.com'; var iFrame = $('#myIFrame'); var iFrameParent = iFrame.parent(); iFrame.remove(); iFrame.attr('src', newUrl); iFrameParent.append(iFrame);
Basically you need to prevent the addition of new history entries in the iframe, history.replaceState introduced in HTML5 would work in most cases.
history.pushState(state, title, url);
No, this is entirely up to the browser.
