我有一個 Angular 12 專案，我想檢索用戶表中的 ArtistryBehaviour 列中的所有結果（除了那些為 NULL 或相同的結果，例如 Actor、Actor）。
我從用戶表中呼叫所有用戶的 ts 函式。
allArtistsSet() {
this.userData.allArtists(this.offset).pipe(
map((data: any) => {
if (data.success) {
this.allArtists = data.artistsFeed;
this.creativenessArtists = this.allArtists.artisticBehaviour;
//this.creativenessArtists = this.allArtists.filter(data.artisticBehaviour)
//this.creativenessArtists = [...this.allArtists.artisticBehaviour];
//return this.creativenessArtists.filter(allArtists => allArtists.artisticBehaviour === this.creativenessArtists);
}
})
).subscribe()
}
嗯。
<select>
<option disabled>Creative Behaviour</option>
<option>Creativeness</option>
<option *ngFor="let creative of creativenessArtists" value="{{creative}}">{{creative}}</option>
</select>

你可以使用filter()函式。

我假設您希望將從 API 接收到的資料存盤在一個變數中，如果是，則使用過濾器的條件，然后這樣做，
allArtistsSet() {
this.userData.allArtists(this.offset).subscribe(
data=>{
if (data.success) {
this.allArtists = data.artistsFeed;
this.creativenessArtists = this.allArtists.artisticBehaviour;
//this.creativenessArtists = this.allArtists.filter(data.artisticBehaviour)
//this.creativenessArtists = [...this.allArtists.artisticBehaviour];
this.creativenessArtists = data.artistsFeed.filter(allArtists => allArtists.artisticBehaviour === this.creativenessArtists);
}
});
}
