我想要一个根据promises响应返回消息的函数,但我无法获得已解析的值。
function create() {
var check = promise1();
var increment = promise2( check );
var create = promise3( increment );
if ( create === 1 ) {
return {
message: `Item with id ${increment} created`,
value: 'OK'
}
} else {
return {
message: `Item not created`,
value: 'FAIL'
}
}
}
var res = create()
// I want it to return the json if the item was created
// but instead they return promises and I have to use then
// I can't think of another way
console.log( res );
如果我向您展示承诺中的代码是什么样的,那会有用吗?
代码要复杂得多,但我试图将其简化到极致。
//解决 编辑:
function create( responsecb ) {
var check = promise1();
var increment = promise2( check );
var create = promise3( increment );
if ( create === 1 ) {
responsecb( {
message: `Item with id ${increment} created`,
value: 'OK'
} )
} else {
responsecb( {
message: `Item not created`,
value: 'FAIL'
} )
}
}
create.then(console.log)
我只需要创建一个回复,它可以对响应做些什么。
