按对象内的值按角度排序数组对象

Question

How get the object by filtering key value inside the object? I have objects below where I need to only pull data which has session_id:23

data = [{ name: "fist Name", session_id : "23", login: "date" }, { name: "Second Name", session_id : "18", login: "date" }, { name: "Third Name", session_id : "23", login: "date" }];

I tried Angular Filter and Map method to filter this out but dosent seem to work for me here.
.pipe(
    map((res) => {
        res => res.filter(res => res.season_id == 23)
        console.log(res);
    })
)

ngOnInit() {
    this._service.getData();
    this._service.updatedPlayer
        .pipe(
            map((res) => {
                res => ress.filter(res => res.season_id == 23)
                console.log(res);
            })
        )
        .subscribe(
            (playerSession) => {
                this.playerSessionUpdate = playerSession;
            }
        )

}

Answer 1

I think you're confusing arrays with streams.

You need to use the filter method of Array, not the filter operator of observables. So if this._service.updatedPlayer contains your observable stream of data, do this:

this._service.updatedPlayer.subscribe(data => {
  this.playerSessionUpdate = data.filter(res => res.season_id == 23);
}

this.playerSessionUpdate will now contain your filtered data.

Answer 2

your pipe method map must return something. So you should actually do

 map((res) => {
          return res.filter(res => res.season_id === 23)
     })
