Difference between [removed].href and top.location.href

Question

Can Anyone tell me the difference between window.location.href and top.location.href ?

And also where to use which one.

And which

Answer 1

top refers to the window object which contains all the current frames ( father of the rest of the windows ). window is the current window.

so top.location.href can contain the "master" page link containing all the frames, while window.location.href just contains the "current" page link.
