Can the 'scrollTo' plugin be used to scroll an iframe? If so, how?

I've been using the 'scrollTo' plugin to scroll my divs, but now I need to implement that same functionality to affect an iframe. Is this possible?

Hello testudo, and welcome to the GreenSock Forum!

 

I have been trying various ways either through jQuery and native javascript to scroll the iframe. But it seems once the iframe is loaded it is not working, especially in Chrome.

 

I tried on codepen but the iframe html page i uploaded to codepen assets would be loading from amazon cdn, so that would invoke a cross domain permission denied. If trying to access an iframe from another domain in codepen, it will give you

Error: Permission denied to access property "scrollTop"

Then when i try to run locally on a testing apache server, i dont get the permission denied error, but no scroll happens. Even though i console out the scroll top position. Which outputs the scrollTop position in my console.log().
 

So i can get the scrollTop position locally on my testing server, but it wont take the set of any value.

After that i tried various other javascript only iframe scrollTo solutions, but it can get the scrollTop value, but it is not working to set a value, even in a loop:

I will keep my eye on this, but either the iframe, even running locally will not set any scrollTo value, even though it gets a scrollTo value of the iframe. I can change various CSS properties through the iframe, and remove/add elements, but I get no scrollTo motion.

 

Maybe someone else can have better luck. But it looks like this is either a bug or something that changed with iframes. Pretty soon the new HTML5 iframe spec will be available allowing cross domain and better https support.
