用户关闭窗口或标签时如何重定向

Question

Is there a way to redirect the window or tab when a user closes it? This does not work (in jQuery):

$(window).bind('beforeunload', function() {
   window.location = 'anotherpage.html'
}

Is it even possible? I just want to redirect a user to another page when they close it.

Answer 1

No, the only thing you can do is alert the user they are about to close your page and ask them if they would like to remain or confirm to leave.

This is very common on pages which require you to save before exiting, like an online exam or survey for example.

  window.onbeforeunload = confirmExit;
  function confirmExit()
  {
      return "You have attempted to leave this page.  If you have made any changes to the fields without clicking the Save button, your changes will be lost.  Are you sure you want to exit this page?";
  }

Answer 2

您无法转到新的网页，但是如果需要做的是打扫房间（例如向服务器发出ajax调用，清除一些cookie等），则可以直接在onbeforeunload处理程序上执行此操作，而无需提示用户，无需重定向。
