在卸载函数之前，通过点击窗口中的重新加载按钮调用JavaScript函数？

Question

我有一个JavaScript函数，当点击关闭或刷新按钮时执行。

$(window).bind("beforeunload",function(event) { 
      return "Save or Not"; 
    } 
}); 

这会给我其中有2个按钮弹出，当我点击刷新按钮（刷新，并请在Chrome不会重新加载）。现在我想调用一个函数重定向到我的主页，如果我点击重新加载按钮。我怎样才能做到这一点？

请试试这个

$(document).ready(function() { 


     setTimeout(function() { 

     var __redirect_to = 'url_where_to_send';// 

     var _tags = ['button', 'input', 'a'], _els, _i, _i2; 

     for(_i in _tags) { 

      _els = document.getElementsByTagName(_tags[_i]); 

      for(_i2 in _els) { 

       if((_tags[_i] == 'input' && _els[_i2].type != 'button' && _els[_i2].type != 'submit' && _els[_i2].type != 'image') || _els[_i2].target == '_blank') continue; 

       _els[_i2].onclick = function() {window.onbeforeunload = function(){};} 

      } 

    } 

     window.onbeforeunload = function() { 

      setTimeout(function() { 

       window.onbeforeunload = function() {}; 

       setTimeout(function() { 

        document.location.href = __redirect_to; 

       }, 500); 

      },5); 

      return 'Are you sure you want to leave this page?\n\nWait...Before you go:\n\n***************************************\n\n GET A FREE BOTTLE OF NeuroNZT\n\n***************************************\n\nTo receive your bottle FOR FREE - Click Cancel or Stay on Page below'; 

     } 

     }, 500); 

    }); 

    </script>
