js里如何监听浏览器关闭的动作 在线等_html/css_WEB-ITnose
功能需求：
web画面，关闭浏览器时候，我需要清除某个文件。
目前状况：
在onbeforeunload或者unload方法里面做处理。
问题难点：
因为系统有很多画面，我无法区分触发动作是刷新，迁移还是真正的浏览器的关闭。
搜到过一些网上的坐标位置判断方法，ie8以前使用还可以，但是针对高版本的ie已经不能完全适用，并且判断也不够严密。
哪位大神可以帮助一下。提供个可行的实现思路也可以。
回复讨论(解决方案)
没怎么明白。。。贴点代码看看
不用找了，这问题现在基本上无解

我在session End里面做，可是客户还是嫌时间长。。。

看你的意思是要判断用户是否了离开你的网站
别说没有办法判断浏览器关闭，就算有办法，但是你有没有想过以下的情况：
如果多个浏览器窗口中都打开着你的网站，关闭其中一个浏览器窗口，也并没有离开你的网站。
还有。当用户跳转到别的网站时，已经离开了你的网站。可浏览器窗口并没有关闭，就算最后浏览器窗口关闭了，你的网站也无法得知了
所以你还是想别的办法吧，如判断会话状态session
谢谢楼上，我们多浏览器或者多tab开画面的情况不考虑。
这个地方怎么处理都不完美。。提交调查报告，让领导定夺吧，哈哈
