angularjs $timeout in Angular14

Question

下面的代码是针对Angular的，我希望在角14中实现相同的功能/行为。

var getData = $timeout(function () {
     return $q(function (resolve, reject) {
        if (someCondition) {
          resolve('data received!');
        } else {
          reject('something went wrong!');
        }
      });
    }, 2000);

和取消行为

$timeout.cancel(getData)

我知道setTimeout可能有一个setTimeout解决方案，但不确定是否应该使用RxJ或RxJ？

Answer 1

应该是这样的：

   const obs$ = of({}).pipe(delay(2000), concatMap(() => {
     if (someCOndition) {
        return of('data received!');
     } else {
        throw new Error('something went wrong!');
     }
   }));

   const subscription = obs$.subscribe(...);
   // if want to cancel
   subscription.unsubscribe();
