rxjs并订阅集合中的新值

Question

我如何从不断变化的来源进行订阅？

$1,i

Answer 1

您应该封装数组，使其与可以观察到的主题紧密结合：

myArray = [1,2,3,4,5];
const observable = new Rx.Subject();
observable.next(myArray);

const subscribe = observable.subscribe(val => console.log(val));

myArray.push(10);
observable.next(myArray);  // after each push reemit the array

myArray.push(11);
observable.next(myArray);
