用ajax怎么传两个集合过去？

Question

$.ajax({
type:"post",
url:"questions/randomQuestion",
contentType:"application/json;charset=UTF-8",
dataType : "json",
data:"tList="+JSON.stringify(typeData)+"&lList="+JSON.stringify(levelData),//将json数据转化为字符串
success:function(data){

            }

Answer 1

var jsondata = {'tList': JSON.stringify(typeData), "lList": JSON.stringify(levelData)};
$.ajax({
type:"post",
url:"questions/randomQuestion",
contentType:"application/json;charset=UTF-8",
dataType : "json",
data:JSON.stringify(jsondata),
success:function(data){}
试试这样写看行不行
