我在具有滚动条的外部 div 中有 div。我可以在滚动时到达外部 div 的末尾时收到警报，但我想在到达每个内部 div 的末尾时收到警报。

html结构如下。

<html><head></head>
<body>
     <div id = "outer" style= "width:200px;height:200px; overflow:auto;">
         <div id = "#1" class = "inner"> blah blah </div>
         <div id = "#2" class = "inner"> blah blah </div>
         <div id = "#3" class = "inner"> blah blah </div>
         <div id = "#4" class = "inner"> blah blah </div>
     </div>
</body>
</html>

我想在到达 div #1、#2、#3、#4 的末尾并且滚动条附加到外部 div 时收到通知。

提前致谢。

HTML：

 <div id = "outer" style="width:200px;height:200px; overflow:auto;">
     <div id = "#1" class = "inner"> blah blah </div>
     <div id = "#2" class = "inner"> blah blah </div>
     <div id = "#3" class = "inner"> blah blah </div>
     <div id = "#4" class = "inner"> blah blah </div>
     <div id = "#5" class = "inner"> blah blah </div>
     <div id = "#6" class = "inner"> blah blah </div>
     <div id = "#7" class = "inner"> blah blah </div>
     <div id = "#8" class = "inner"> blah blah </div>
     <div id = "#9" class = "inner"> blah blah </div>
     <div id = "#10" class = "inner"> blah blah </div>
     <div id = "#11" class = "inner"> blah blah </div>
     <div id = "#12" class = "inner"> blah blah </div>
 </div>​

JS：

jQuery(
  function($)
  {
    $('#outer').bind('scroll', function()
    {
      if($(this).scrollTop() + $(this).innerHeight()>=$(this)[0].scrollHeight)
      {
        alert('end reached');
      }
    })
  }
);​
