我有一個 angular 8 應(yīng)用程序和一個包含兩個值的下拉列表：在后端，兩個值的名稱是：已邀請和已注冊。但在前端，它們被稱為：Open en afgerond：public statusOptions = {    Registratie: ["Open", "Afgerond"],    VCheq: ["Ongeopend", "Open", "Afgerond", "Verlopen"],    Doelen: ["Tussentijds doel behaald", "Geen data sinds", "Eind doel behaald"],    Qrcode: ["Gescanned", "Niet gescanned"],    Inlog: [],    Chat: []  };我有一個這樣的 api 調(diào)用：filerByRegistration() {    console.log(      this.participantService        .filterParticipantsByRegistration(1, this.statusOptions['Invited'], moment(this.startDate).format("YYYY MM D"))        .subscribe(filterByRegistration => {          // this.startDate = filterRegistration.start.value;          this.statusOptions[''] = filterByRegistration;          console.log(this.otherOptions['Invited'] = filterByRegistration);          this.filterparticipantByRegistration.emit(filterByRegistration);          console.log(this.startDate.toString());          console.log(filterByRegistration);        })    );  }組件的模板如下所示：<div  class="filter-plus mat-elevation-z8"  [ngClass]="{ expanded: searchExpanded }">  <div class="filter-plus-search-fields">    <div class="search-types">      <mat-radio-group>        <mat-radio-button          *ngFor="let option of searchOptions"          [value]="option"          (change)="setSelectedSearchOptions(option.label)"        >          {{option.label}}        </mat-radio-button>      </mat-radio-group>    </div>    <div class="search-selects">      <div        class="search-select searchstatus"        *ngIf="selectedSearch && hasStatusOptions(selectedSearch)"      >        <mat-select placeholder="Status" name="option">          <mat-option            *ngFor="let option of getStatusOptions(selectedSearch)"            [value]="option"          >            {{ option }}          </mat-option>        </mat-select>      </div>
