mui 代码

mui.plusReady(function() {
var url = "http://192.168.1.110/app.php?op=shop_list&id=2";
mui.ajax(url,{
dataType:"json",
type:"get",
timeout:1000,
success:function(data){
/var list=document.getElementById("list");
var finallist='';
for(var i=0;i<data.length-1;i++){
//alert(data[i].title)
finallist=finallist+'<li class="mui-table-view-cell"><a class="mui-navigate-right"><div class="mui-media-body">'+data[i].title+'<p class="mui-ellipsis">'+data[i].username+'</p></div></a></li>';
}
list.innerHTML=finallist;
/
alert(data);
},
error:function(data){
finallist='加载失败';
list.innerHTML=finallist;

            }  
        });  
        })  

到底是错在哪里呢 郁闷一次不出现数据 去掉 dataType:"json", 又可以出现 是JSON格式错误么
请老司机指点一下
