有没有办法通过javascript检测关闭页面？

I watched a few threads here,mostly used this: window.onbeforeunload = function (e) { var e = e || window.event;

我在这里看了几个线程,主要用于:window.onbeforeunload = function(e){var e = e || window.event;

//IE & Firefox if (e) { e.returnValue = 'Are you sure?'; }

// IE和Firefox if(e){e.returnValue ='你确定吗?'; }

// For Safari return 'Are you sure?'; };

//对于Safari返回'你确定吗?'; };

but seems this will mix the situation of refreshing page and close page, is there any possibility to distinguish these two situations?

但似乎这会混合刷新页面和关闭页面的情况,有没有可能区分这两种情况?

2 个解决方案

function OnUnLoad()
{
    if (window.event.clientY < 0 && window.event.clientX < 0)
    {
        //cleanup code goes here...
    }       
}

This seems to work for me on all browsers. But closing tabs seems to cause issues. Actually, there is not "documented" way of doing it.

这似乎适用于所有浏览器。但是关闭标签似乎会导致问题。实际上,没有“记录”的方式。
