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 /**
* 上拉加载具体业务实现
*/
// var n=1;
function pullupRefresh() {
setTimeout(function() {
mui('#pullrefresh').pullRefresh().endPullupToRefresh((++count > <?php echo $page?$page:0?>)); //参数为true代表没有更多数据了。
var table = document.body.querySelector('.mui-table-view');
var cells = document.body.querySelectorAll('.mui-table-view-cell');
// var len=10; var res=[];
$.ajax({
url: '__CONTROLLER__/messageAjax',
