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：
// 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);
方法二：
// 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);
希望本文所述对大家的javascript程序设计有所帮助。
