这篇文章主要介绍了js实现防止被iframe的方法,实例分析了两种比较常用的javascript防止页面被iframe的技巧,非常简单实用,需要的朋友可以参考下
本文实例讲述了js实现防止被iframe的方法。分享给大家供大家参考。具体如下:
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>
希望本文所述对大家的javascript程序设计有所帮助。
