Closes the window.
A window is script-closeable if it is either a window that was opened by another window, or if it is a window with only one document in its history.
A window might not be allowed to navigate, and therefore close, another window due to browser security features.
var other = window.open('http://www.example.com', 'foo'); // Closes other window, as it is script-closeable. other.close(); print(other.closed()); // 'true' window.location('http://www.mysite.com', 'foo'); // Does not close this window, as the history has changed. window.close(); print(window.closed()); // 'false'
