這篇文章主要介紹了js實(shí)現(xiàn)防止被iframe的方法,實(shí)例分析了兩種比較常用的javascript防止頁面被iframe的技巧,非常簡(jiǎn)單實(shí)用,需要的朋友可以參考下

本文實(shí)例講述了js實(shí)現(xiàn)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(duì)大家的javascript程序設(shè)計(jì)有所幫助。
