Javascript：当页面被导航时检测到“返回”至 [英] Javascript: detect when page has been navigated "back" to

问题描述

假设我在浏览器中打开了一个页面，然后进入我的地址栏并输入另一个页面。然后我点击后退按钮进入我的原始页面。我想写一些Javascript代码，可以检测到这种情况并作出回应。

尽我所知，准备就绪事件， onload 以及页面上的任何内联Javascript都会在此场景中重新执行。还有什么我可以做的吗？

跨浏览器支持在这里很重要。

编辑为了清楚起见：我假设的导航是页面A - >页面B - >返回页面A，我在哪里假设页面B可能或不可以在我的控制之下。 解决方案

http://benalman.com/projects/jquery-bbq-plugin/ 似乎很适合，如果你考虑一个Jquery插件。

Suppose I have a page open in a browser and I go to my address bar and enter another page. Then I hit the back button to go to my original page. I'd like to write some Javascript code that can detect this scenario and respond to it.

As best I can tell neither the ready event, the onload, nor any inline Javascript on the page itself is re-executed in this scenario. Is there anything else I can do?

Cross-browser support is important here. jQuery based solutions preferred but not required.

Edit for clarity: the navigation I'm assuming is Page A -> Page B -> back to page A where I'm assuming that Page B may or may not be under my control.

解决方案
