我想提取 filterPillvalue 并將其放入一個數組中，數組的輸出應該是這樣的：mode = ['anyValue','Repsonding','Unresponsive']這是我的嘗試this.items = [  {    filterPillValue: 'anyValue',    id: 'all-systems',    label: 'All systems'  },  {    filterPillValue: 'Responding',    id: 'responding',    label: 'Responding systems'  },  {    filterPillValue: 'Unresponsive',    id: 'unresponsive',    label: 'Unresponsive systems'  }];我的嘗試在這種情況下不起作用mode = this.items.filter(x=>x.filterPillValue);
