开始总结自己在项目上的使用AJAX的情况：
该图为向后台请求的数据，前台返回的结果，返回的数据类型为object，businessObj由许多key组成，我们项目前台需要调用的数据就藏在数组records中，可以通过
var records=data['businessObj']['records'];
将records打印出来，输出的内容为一个数组（我们项目中数组长度为1，项目初期，内容有点少，/(ㄒoㄒ)/~~~）,每个数组又是由一个对象组成。
下面上代码喽！！！！！！！！！！！！！！！！！！
1 var count = 0;
2 /** 3 * 上拉加载具体业务实现 4 */ 5 // var n=1; 6 function pullupRefresh() { 7 setTimeout(function() { 8 mui('#pullrefresh').pullRefresh().endPullupToRefresh((++count > <?php echo $page?$page:0?>)); //参数为true代表没有更多数据了。 9 var table = document.body.querySelector('.mui-table-view'); 10 var cells = document.body.querySelectorAll('.mui-table-view-cell'); 11 // var len=10; 12 13 var res=[]; 14 $.ajax({ 15 url: '__CONTROLLER__/messageAjax', 16 type: 'post', 17 dataType: 'json', 18 data: {pageIndex: count,type:'activity'}, 19 }) 20 .done(function(data) { 21 22 var records=data['businessObj']['records']; 23 console.log(records); 24 25 var len=records.length; 26 for (var i = 0; i < len; i++) { 27 var li = document.createElement('li'); 28 li.className = 'mui-table-view-cell'; 29 li.className = 'mui-table-view-cell'; 30 li.innerHTML += '<p class="hdate">'+records[i]['sendTime']+'</p>'
