say have iframe running inside of parent window.

i have single script loaded inside iframe , want script have access variables inside of parent.

rather saying window.parent.x time, possible declare: 

window= window.parent;

inside of iframe?

window protected variable js, not able override it. can, however, store window.parent in var , use that:

var parentwindow = window.parent;
