Getting parents document from iFrame

Question

I have seen some elegant solutions on fetching the parents document from iframe - like e.g. this one. However, I can\'t make it work - and I didn\'t think this was possible

Answer 1

It's still possible to access the parent from within a frame provided that the domains match.

For example, have a look at these fiddles:

• Frame host: fiddle.jshell.net, parent host: fiddle.net Does not match = failure
  Test #1: http://jsfiddle.net/nrRQg/1/
• Frame host: jsfiddle.net, parent host: jsfiddle.net **Matches = success*
  Test #2: http://jsfiddle.net/nrRQg/1/show/

You can access the parent through:

window.parent
parent
top          //If the parent is the top-level document
window.top

The variables parent and top can be overwritten (usually not intended). It's safer to use window.parent to be more safe. Alternatively, you can replace window by document.defaultView.
