Answer 1

I know this question is quite old but in case you run into this I'd suggest you use JSON.parse to create an object on the parent frame rather than eval because eval is evil (causes security issues, I think it's disabled by default in some browsers too nowadays)

for example, if you want to call someFunction on frame 1, passing it a JSON object, use something like the below:

var frame = window.frames[1];
frame.someFunction( frame.JSON.parse( '{ "attr": 7 }' ) );
