Call method inside iframe that holds a Cesium map

问题

I can normally call a method that is inside the html of an iframe using this approach:

document.getElementById("frame_id").contentWindow.method_in_frame();

I can also call methods outside the iframe using the parent approach:

onclick="parent.method_outside_frame(); 

But if my iframe is holding an instance of the Cesium map this does not work. Does cesium having something that stops this from happening? Is there a way to override it?

Found the answer. You need to change the default security on Cesium with this line:

viewer.infoBox.frame.sandbox = "allow-same-origin allow-top-navigation allow-pointer-lock allow-popups allow-forms allow-scripts";

Then, if you are creating any methods in the Cesium popups you need to add the parent call which allows the button to reference back to the container level.:

onclick="parent.method_outside_frame();"
