js實現防止被iframe的方法
編輯:關於JavaScript     

本文實例講述了js實現防止被iframe的方法。分享給大家供大家參考。具體如下:

方法一:

<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>

方法二:

<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>

希望本文所述對大家的javascript程序設計有所幫助。
