Question

我有三个不同的div。现在，所有三个div如果我正在向下滚动然后我应该调用一个调用ajax的JavaScript函数。以下是我的尝试。这里的数据来自于准备好的文档上的ajax，这里的数据来自id ='doc'，id ='user'，id ='lawfirms'。因此，您无法看到项目，因为所有div都是动态创建的。

<script>
var processing;
$(document).ready(function(){
var lastScroll = 0;
    $(".doc_ary").scroll(function(e){
        var st = $(this).scrollTop();
        if(st > lastScroll)
        {
        var st = $(this).scrollTop();

        if (processing)
            return false;
            if ($(window).scrollTop() >= ($(document).height() - $(window).height())*0.6){
            doc_ary();
        }
       } 
    });
});
</script>
<script>
var processing;
$(document).ready(function(){
var lastScroll = 0;
    $(".user_ary").scroll(function(e){
        var st = $(this).scrollTop();
        if(st > lastScroll)
        {
        var st = $(this).scrollTop();

        if (processing)
            return false;
            if ($(window).scrollTop() >= ($(document).height() - $(window).height())*0.6){
            user_ary();
        }
       } 
    });
});
</script>
<script>
var processing;
$(document).ready(function(){
var lastScroll = 0;
    $(".lawfirms_ary").scroll(function(e){
        var st = $(this).scrollTop();
        if(st > lastScroll)
        {
        var st = $(this).scrollTop();

        if (processing)
            return false;
            if ($(window).scrollTop() >= ($(document).height() - $(window).height())*0.6){
            lawfirms_ary();
        }
       } 
    });
});

它的工作。使用以下代码，

<script>
var processing;
$(document).ready(function(){
  alert('function_called');
  var div1=$("#div_doc_ary");
  var lastScroll = 0;
    $(div1).scroll(function(e){
        var st = $(this).scrollTop();
        if(st > lastScroll)
        {
        var st = $(this).scrollTop();
        if (processing)
            return false;
        if ($(window).scrollTop() >= ($(div1).height() - $(window).height())*0.7){
            alert('scrollDownCalled');
            offset=++offset;
            processing = false;
         });
        }
       } 
    });
});
</script>

在向下滚动特定div时调用JavaScript函数？
