如何在打开的选项卡上检测URL更改

Question

I have to open a new tab in javascript and I would like to be noticed (on the main tab, the first one), if the user close the tab or if the user change the url. I know that if the second tab is on an other domain, you cannot access to the location attributes and I understand. But is there any way to detect if the user changes the URL of the child tab ? A kind of bit or flag giving me this information ?

In advance, thank you.

更改URL将导致页面的重新加载，因此您应该检测何时重新加载页面，因此： 检查是否用Javascript重新加载或刷新了页面。
