Spring MVC前端与后端5种ajax交互方法【总结】

ajaxPost("/base/user/exchangeSort",{"id":rid,"otherid":otherid},function(data,status){

xxxxxx

xxxxxx

});

var ={id:id};

ajaxPost("/base//getOrgById", ,function(data,textStatus){

xxxx

xxxx

});

var ueser={id:rowId};

var data=ajaxPost("/base/user/findById",{"userObj":JSON.stringify(user)},null);

var ueser={ };//创建对象

user["id"]=id;

user["name"]=$("#name").val();

user["dept"]={};//外键对象

user["dept"]["id"]=$("#deptid").val();

ajaxPost("/base/user/addUser",{"userObj":JSON.stringify(user)},function(data){xxxx;xxxxx;});

@RequestMapping("/findById")

//不推荐这样的写法
