滚动条向下滚动事件

<script src="/js/m/jquery-2.0.0.min.js"></script>

<script type="text/javascript">

var pageCount = ${pageCount};
var page = 1;
var keyword = '${keyword}';

var is_continue = true;

function is_need_scroll(){

    if(is_continue){
      return jQuery(document).scrollTop() + jQuery(window).height() > (jQuery(document).height() - 50);
     
    }else{
      return false;
    }
   
}

jQuery(window).unbind("scroll").bind("scroll",function() {

if(is_need_scroll()){

is_continue = false;
var url = "/mp/queryeventinfo.htm";

$("#hideContentLoad").load(url,{page:page,keyword:keyword,jsp:2}, function() {

  $(".active_content").append($("#hideContentLoad").html());
  if(page==pageCount){
  is_continue = false;
  }else{
  page++;
  is_continue = true;
  }
});

}

});
</script>
<div class="active_content">

</div>

<div id="hideContentLoad" style="display: none;"></div>

注意：写一个jsp页面，用来循环显示列表的内容
