const s$ = new Rx.Observable.interval(100).take(4);
const s1$ = s$.map(v => 's1:' + v);
const s2$ = s$.map(v => 's2:' + v);
Rx.Observable.combineLatest(s1$, s2$)
.subscribe((value) => {
console.log(value);
})
我想要这样的输出:
s1: 1, s2: 1
s1: 2, s2: 2
s1: 3, s2: 3
但实际输出:
“ s1:0,s2:0”
“ s1:1,s2:0”
“ s1:1,s2:1”
“ s1:2,s2:1”
“ s1:2,s2:2”
“ s1:3,s2:2”
“ s1:3,s2:3”
我该怎么办?
答案 0 :(得分:0)
改为使用zip运算符:
Rx.Observable.zip(s1$, s2$)
.subscribe((value) => {
console.log(value);
})
