Instead of
代替
show = false;
try
尝试
window.onbeforeunload = null;
This will simply unbind the function from the event.
这将简单地解除函数与事件的绑定。

I just ran into the same problem and found a very easy solution:
我刚刚遇到了同样的问题，并找到了一个非常简单的解决方案：
$("a").mousedown(function() {
$(window).unbind();
});
This will remove the onbeforeunload event just before the click event is triggered.
这将在触发 click 事件之前移除 onbeforeunload 事件。
