请问如何把从浏览器获得的json数据先重新排序再进行操作？

怎么先从浏览器拿到基本的json数据，再根据日期进行排序，然后再放到相应的容器里？

function to_page(pn){
    $.ajax({
        url:"/AJ-bbs1/AJtopic",
        data:"pn="+pn,
        type:"GET",
        success:function(result){

            build_AJ_table(result);
            build_page_nav(result);


        }
    });
}


function build_AJ_table(result){
    //列表信息
    //每次都清空列表
    $("#AJlist").empty();
    var AJ= result.extend.pageInfo.list;

    $.each(AJ,function(index,item)
            {








         var time = $("<td></td>").append(item.ttime).addClass("c1");
         var ttopic = $("<td></td>").append(item.ttopic).addClass("c2");

          var uname = $("<td></td>").append(item.tuid).addClass("c3");
          var runame = $("<td></td>").append(item.treply).addClass("c4");
            var edibtn = $("<button></button>").append("编辑");
            var delbtn=$("<button></button>").append("删除");
            var c4 = $("<td></td>").append(edibtn).append(delbtn).addClass("c4");



        if(this.tsid == 1){
         var tr= $("<tr></tr>").addClass("row1_topicrow").append(time).append(ttopic).append(uname).append(runame).append(c4).appendTo("#AJlist");
        }



            });
}

我想拿到json里面的ttime时间进行排序后再放进容器
我知道有sort(),但是具体该怎么操作？试了很多写法都不行。
