javascript - 如何在 RXJS 订阅中运行多个条件

Question

我正在从模态中获取数据，我需要检查结果并根据许多条件确定要触发哪个外部函数。

我已经验证了传回的数据格式正确，并且应该触发一系列 else if，但看起来它会跳过所有条件并且不执行任何操作。

实现此逻辑最有效的方法是什么？

我的代码:

dialogRef.afterClosed().subscribe(result => {
    console.log('RESULT: ', result.delete);



    if (result.isNew && !result.cancel) {
      console.log('new story!');
      this.boardService.updateTasks(this.job.id, [
        ...this.job.tasks,
        result.task
      ]);
      this.closeStories('update', this.job)
    } 
    // means a delete has occured
    else if (result.delete) {
      this.closeStories('deleted triggered...')
      // last story has been deleted, prompt newStory
      if (this.stories.length < 2 && result === {}) {
        console.log('Last story was deleted!');
        this.closeStories('delete')
      }
      // a delete has happened
      else if (this.stories.length > 1 && result === {}) {
        console.log('A story was deleted!');
        this.closeStories('deletedLast')
      }
    }
    // means an update has occured
    else if (result.id && !result.isNew) {
      console.log('A story was Updated!');
      const update = this.stories;
      update.splice(result.index, 1, result.task);
      this.boardService.updateTasks(this.job.id, update);
      this.closeStories('update', this.job)
    }
    else if (result === undefined) {
      return 0
    }
    // this.closedStoryListEmitter.emit(this.job);
    console.log('hit close list event emitter!!');
  });

//Have you checked other callbacks
dialogRef.afterClosed().subscribe(
    result => {
        console.log('RESULT: ', result.delete); //does this console.log executes?
        //rest of the code
    },
    error=>{
        //do something with and error
    },
    ()=>{
        //finished
    }
);
