在网上找到解决办法特随笔：

原因：ajax默认是异步提交，可是有时候我们会发现,本来要求请求马上出现,可是异步会导致后面突然再执行,这样就出问题了。

解决办法：

function jie(){

        $.ajax({

            url:"http://127.0.0.1:8000/userctrl/orders",

            data:{'user':$.cookie("username"),"good_name":$(".good_name").text(),},

            type:"post",

            async:false,

            dataType:"text"，
　　　　　　　success:function(obj){

　　　　　　　　})

　　　　　})

    }
