Calling iframe function

Question

Is there a way to call a JavaScript function that is inside an IFrame from the parent?

Answer 1

That depends on the contents of the IFrame. If the content is from another domain then you're out of luck, as most modern browsers have closed that loophole for cross-site attacks.

However, if the content is from the SAME domain then you can use it as it were simply another method on the IFrame window object. If I recall correctly you can use something like window.frames["_your_IFrame_ID_"].window.functionOrMethodName().
