我试图找出如果下面是可能与现有的任何运营商在RxJS,或者如果我需要推出自己的分机:如何获得像RxJS订阅模式的承诺?
var x = // some observable sequence
var y = // some observable sequence
var z = // some observable sequence
// 'when' should only call onNext when all of x, y and z has returned at
// least one value. After that, 'when' should continue to call onNext if
// any of x, y, z changes their value.
var w = Rx.Observable.when(x, y, z).select(function(x, y, z) {
// do stuff values of from z, y, x.
});
最佳,埃吉尔。
