javascript - Getting the scrollTop() value of an element inside an Iframe -

Is it possible to get the scrollTop or offset value of an element inside the iframe? E.g.

  $ ("iframe"). Content (". ControlPanel"). ScrollTop ();  

Or is there any other way possible?

Since null

You have addressed that there is no effect on the contents of the IFrame, there is no way to open the javascript inside it. It has to be done with cross-domain policies.
