由JavaScript检查浏览器标签？ [英] Check browser tabs by JavaScript?

问题描述

我可以检查是否为JavaScript主页是活动的浏览器IE7中/ FF /歌剧标签？

Can I check if host page for a JavaScript is active by the browser's tab in IE7/FF/Opera?

检查其他选项卡不到哪里这个JS运行可能会带来安全隐患，虽然页面..

Checking other tabs than the page where this JS runs would probably be a security risk though..

我的另一种选择是我记得的原型，以检查是否鼠标光标被激活的方法，但它不是那么准确。

My other option is a method I remember by prototype to check if the mouse cursor is active, but it's not that accurate.

推荐答案

您可以附加的onblur 和的onfocus 事件到窗口;这可以告诉你，如果你有焦点。我测试了这一点，它的工作原理。您不能检查另一页，但你绝对可以检查你自己的。

You can attach the onBlur and onFocus events to the window; that will tell you if you have focus or not. I have tested this and it works. You cannot check another page, but you can definitely check your own.
