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
Javascript 是一种由 Netscape 的 LiveScript 发展而来的原型化继承的基于对象的动态类型的区分大小写的客户端脚本语言,主要目的是为了解决服务器端语言,比如 Perl,遗留的速度问题,为客户提供更流畅的浏览效果。
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。
