如何从 Observable 获取价值

Question

请问您是否知道如何从：

获取 _value

我有这个功能：

jobsLength(){
   const jobslength:any;
   jobslength=this.searchLogic.items$
   console.log(jobslength)
};

Answer 1

您需要订阅 items$ Observable 以获取数据。

jobsLength() {
   this.searchLogic.items$.subscribe((value: any[]) => {
       let jobs: any[] = value;
       console.log(jobs);
       console.log(jobs.length);
   });
}
