Tile - scroll top-level window from inside iFrame?

butch Jan 22, 2016 12:11 PM

We have gadgets.window.adjustHeight/adjustWidth.

Aare there any plans to implement a mechanism for scrolling the top level window from inside the iFrame?

I ask because of the possibility of configuring the iFrame in a sub-sub domain - which would render our current methods of doing this from a same-domain iFrame worthless.

Thanks!

I am not familiar with an OpenSocial spec that does this ... and in general I haven't heard of this in any conversations. Could you share some of the use-cases, and I'll try to document the request for consideration?

  Hey Ryan,
  
  This video best demonstrates the user experience we want to guarantee. This is done using hackery right now though that cannot be guaranteed if tiles/canvas views are in different domains.

Yuval Twig Edward Venaglia - Any thoughts on this one? Specifically in an environment with high app security (different domains).

Basically a Tile.onFocus event that the Tile can call after adjustHeight()?

  Hey Ryan - I'm envisioning a little bit different of an interface. Here is the code we're currently calling:
  
  var header_height = 0;
  var header_height = window.parent.jQuery("#j-header-wrap").outerHeight();
  
  window.parent.jQuery("html, body").animate({
  scrollTop: window.parent.jQuery(window.frameElement).offset().top - header_height
  }, 500);
  
  What would be useful is an interface for adjusting the scrollTop of the window.top element. Maybe:
  
  gadgets.window.scrollTop() -> Get scrollTop
  gadgets.window.scrollTop(50) -> Set scrollTop
  
  or... even...
  
  gadgets.window.scrollToFocus() -> Scroll viewport to the top of this tile?

    Hey Butch Marshall, until that's built into the gadgets api, how about a different hack?
    
    I was able to get effectively a "scroll to top" by calling adjustHeight with a small value, then calling it again with no value. Essentially forcing the scroll by making the iframe tiny which would scroll the page up to the top of the iframe. I also had to delay the second call since the adjustHeight doesn't have a callback parameter.
    
    gadgets.window.adjustHeight(10); setTimeout(gadgets.window.adjustHeight, 200);
    
    You should be able to roll your own scroll to top method by calling the gadgets.rpc.call function and passing adjustHeight as it's callback, but for some reason the callback didnt seem to be called for me, this is why i went for the extra hacky timeout call. 200ms seemed to be sufficient in my test, but YMMV, it may depend on the exisitng height of the pane as it resizes somewhat smoothly. With 100ms, it seemed to scroll about halfway up before the full resize stopped it.

      Hi Scott A Johnson - this doesn't really produce the behaviour that we're hoping for.
      
      It's more of a jump-close-to-top rather than a nice and smooth scroll up that we can get with the jQuery execution method?
      
      Do you or Ryan Rutan have any suggestions that would allow me to produce the behaviour shown in my GIF?
      
      Thanks!

        Sorry just to add, with additional testing I've encountered that this only adjusts the pages height if:
        
        1) the iFrame you want in focus is at the very bottom of the page.
        or
        2) the iFrame is the largest iFrame on the page.

      Thanks very much for suggesting this workaround Scott! It's not perfect, but it's definitely better than nothing. +1 to the Jive team on the request to add a more robust solution to the Javascript API - some kind of function that would allow us to scroll the parent window from the custom tile.

  One idea would be the postmessage function of browsers which allows cross origin communication.
  I have already used that in the past for another platform which integrates addons via Iframes...
  
  Window.postMessage() - Web APIs | MDN
  
  Almost all browsers support it and if you validate the source of the caller it is a very safe approach...
  
  Thanks
  Jens

  Any Progress here? Should WE create an idea for that, Ryan Rutan ?
  
  Thx

      Unfortunately, no. Will need to see what pans out from the Engineering Team re-orgs before there will be any insight as to priority, cadence, etc... for these items. Wish I had a better answer. =\

        This is a small fix that will improve the Jive experience for most of your clients today or in the coming months. I'll suggest the voice of the customer be added to this thread so it's not just a partner ask.
