Выйти из iframe онлайн урок.




if (top.location!= self.location) {
top.location = self.location.href;
}

Это, как правило, работает, но есть небольшая вероятность сбоя в том, чтоокнопереопределено. Вот пара умных альтернатив от Натана Смита :

<script>

// Break out of an iframe, if someone shoves your site
// into one of those silly top-bar URL shortener things.
//
// Passing `this` and re-aliasing as `window` ensures
// that the window object hasn't been overwritten.
//
// Example:
// var window = 'haha, punked!';
//
// Note: Probably unnecessary, but just for kicks.

(function(window) {
if (window.location !== window.top.location) {
window.top.location = window.location;
}
})(this);

</script>

<script>

// A more cryptic one-liner, to awe & impress.
//
// No need to protect `window` since `this` is
// immutable, and at the topmost level means
// `window` anyways. Here, we compare locations
// on the left side of the "&&" and execute the
// code in parenthesis if that condition is
// true (top location isn't iframe location).
//
// Otherwise, nothing happens. It's basically an
// if statement without wrapping curly brackets.
//
// Weird, I know. But pretty cool, right? :)

this.top.location !== this.location && (this.top.location = this.location);

</script>
