是否可以在弹出窗口中检测用户点击事件？ [英] Is it possible to detect the user click event in the popup window?

问题描述

如果当前网址和弹出网址使用以下代码在同一个域中，我可以在弹出窗口中检测用户点击事件。

I can detect the user click event in the popup window if the current url and popup url is in same domain using the following code.

var myWindow = window.open("abc.html","MsgWindow", "width=500","height=600");
$(myWindow).on('click', 'a', function() {alert('a')});

但是，是否可以从外部URL检测用户活动，如下所示。？

But, Is it possible to detect the user activity from the external url as below.?

var myWindow = window.open("http://google.com","MsgWindow", "width=500","height=600");
$(myWindow).on('click', 'a', function() {alert('a')});

第二个片段对我不起作用。我怎样才能让它发挥作用。

The second snippet is not working for me. How can I make it work.

提前致谢。

推荐答案

不，你不能因为SOP（同源政策） http://en.wikipedia.org / wiki / Same-origin_policy

No you can't becouse of SOP (Same Origin Policy) http://en.wikipedia.org/wiki/Same-origin_policy

举个例子：
您可以使用登录信息弹出一个网页。使用您的方法，您可以跟踪登录信息的键输入。用户名和密码。那将是一个重大的安全问题。

To give you an example: You make a popup to a webpage with a login. With your method you are able to track the key input of the login information. username and password. Thats would be a major secutiry issue.
