確認之前onbeforeunload

Question

我需要在用戶離開頁面之前提示用戶，確認後關閉該選項卡，如果不做任何事情。我想發送onbeforeunload上的ajax電話。

我唯一的想法是寫兩個onunload和onbeforeunload這樣的處理程序：

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

但這似乎並沒有的jsfiddle

Answer 1

它在這個小提琴中工作正常 - > 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;

工作只需將他們所有的內部onbeforeunload

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