thinkPHP+LayUI 流加载实现功能

div class="layui-container" id="container"> /div>

layui.use('flow', function() {
  var $ = layui.jquery;
  var flow = layui.flow;
    flow.load({
    elem: '#container' //流加载容器
      //滚动条所在元素，一般不用填，此处只是演示需要。
    ,done: function(page, next){ //执行下一页的回调
     console.log(page)
     //模拟数据插入
     setTimeout(function(){
      var lis = [];
      var url = "/index/index/ajaxNews/?page="+page
      $.get(url,function (res) {
