代码如下：
var query = new AV.Query('StuCouMap');
query.include('student');//此处用了include
query.find().then(function(res){
for(var i in res){
var res=res[i];
var student=res.get('student');
var qiandaoNow=res.get('qiandaoNow');
console.log(student);
console.log(qiandaoNow);
}
});
var query = new AV.Query('StuCouMap');//相同的代码，没用include
query.find().then(function(res){
for(var i in res){
var res=res[i];
var student=res.get('student');
var qiandaoNow=res.get('qiandaoNow');
console.log(student);
console.log(qiandaoNow);
}
});
console的结果
"Please use AV.init() to replace AV.initialize() ."
第一次的结果：
undefined //(student没了 why?????）
[object Object] {
beizhu: "身体不适",
dateleaver: [object Date] { ... },
values: 3
}
第二次的结果
[object Object] { //student存在 why????
