我有myPeople函数,在其中调用这样的promise函数
var myPeople = function(){
var go;
return new Promise (function(resolve){
User
.getPeople()
.then(function(allPeople){
go = allPeople;
//console.log(go)
resolve(go);
})
})
return go;
}
如果我在块中记录我的内容,我会得到我的对象,但我无法让它返回此对象..

将承诺链接起来 - 避免then(success, fail)
反模式:
var myPeople = function(){
return User.getPeople()
.then(function(allPeople){ //
console.log(allPeople);
return allPeople.doSomething(); // filter or do whatever you need in
// order to get myPeople out of
// allPeople and return it
});
});
}
然后在外面:
myPeople.then(function(people){
console.log(people); // this will log myPeople, which you returned in the `then`
});
