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。
