确认之前onbeforeunload

Question

我需要在用户离开页面之前提示用户，确认后关闭该选项卡，如果不做任何事情。我想发送onbeforeunload上的ajax电话。

我唯一的想法是写两个onunload和onbeforeunload这样的处理程序：

window.onbeforeunload = function(){ 
    return 'Are you sure you want to leave?'; 
}; 
window.onunload = function(){ 
    $.get(
     "http://www.mysite.com/php/myhandler.php", 
     { data: 1 } 
    ); 
}; 

但这似乎并没有的jsfiddle

它在这个小提琴中工作正常 - > Perfectly working fiddle!!!

function warning(){ 
      if(true){ 
       return "You are leaving the page"; 
       $.ajax({ 
         url: "test.php", 
         type: "post", 
         data: values to send 
         }) 
      } 
     } 
     window.onbeforeunload = warning; 

Answer 2

工作只需将他们所有的内部onbeforeunload

window.onbeforeunload = function(){ 
    $.get(
     "http://www.mysite.com/php/myhandler.php", 
     { data: 1 } 
    ); 
    return 'Are you sure you want to leave?'; 
};
