JavaScript Trigger function when bottom of iframe reached trigger function when div is visible,trigger function when option

I have an iframe that adjusts it's size dynamical. I solved this with a post message and a listener on the parent page, so everytime the content of the iframe changes the iframe size will too and there will never be a scroll bar.

In the iframe I am showing a list and everytime the bottom of the iframe is reached, I want to append new items to the list.

For me it would also work to trigger the function when the bottom of the parent page is reached, so i tried:

document.getElementById('targetFrame').contentWindow.targetFunction();

But it is forbidden due to cross domain origin.

Is there a way to accomplish what I am trying to do?
