1.引入css、js 

 <link rel="stylesheet" href=" ${pageContext.request.contextPath}/dist/dropload.css">

<script src="${pageContext.request.contextPath}/dist/dropload.min.js"></script>

2、

  $('.list').dropload({
	        scrollArea : window,
	        domUp : {
	            domClass   : 'dropload-up',
	            domRefresh : '<div class="dropload-refresh">↓下拉刷新</div>',
	            domUpdate  : '<div class="dropload-update">↑释放更新</div>',
	            domLoad    : '<div class="dropload-load"><span class="loading"></span>加载中...</div>'
	        },
	        domDown : {
	            domClass   : 'dropload-down',
	            domRefresh : '<div class="dropload-refresh">↑上拉加载更多</div>',
	            domLoad    : '<div class="dropload-load"><span class="loading"></span>加载中...</div>',
	            domNoData  : '<div class="dropload-noData">暂无数据 </div>'
