按字母顺序对一组对象进行排序

Question

我正在尝试按字母顺序对对象数组进行排序，为了使事情变得简单，我正在使用以下示例。在我的打字稿中，我进行拼接以从数组对象中插入和删除项目。

大批

  cars = [{
        id: 1,
        items: [{
          name: 'car1',
          description: 'this is car1 description'
        },{
          name: 'car2',
          description: 'this is car2 description'
        },{
          name: 'car3',
          description: 'this is car3 description'
        },{
          name: 'car4',
          description: 'this is car4 description'
        },{
          name: 'car5',
          description: 'this is car5 description'
        }]
   }];

html

<p-dataView [value]="cars" [paginator]="true" [rows]="5">
  <p-header>List of Cars</p-header>
  <p-footer>Choose from the list.</p-footer>
  <ng-template let-car pTemplate="listItem">
      <p-fieldset legend="Header" *ngIf="car.id === 1" [toggleable]="true">
          <div *ngFor="let _car of car.items">
              {{_car.name}} - {{_car.description}}
          </div>
      </p-fieldset>
  </ng-template>
</p-dataView>

  cars = [{
        id: 1,
        items: [{
             Model:[{  
                        name: 'car1',
                        description: 'this is car1 description'
                   }],
             Model:[{  
                        name: 'car2',
                        description: 'this is car2 description'
                   }],

        },
           id:2,
            items: [{

               Model:[{  
                        name: 'car13,
                        description: 'this is car3 description'
                   }],
             Model:[{  
                        name: 'car4',
                        description: 'this is car4 description'
                   }],
        }]
   }];

我试过

cars[0].items.Model.sort((a,b) => a[0].name > b[0].name ? 1 : -1) //It did not work

也试过

cars[0].items.Model.sort(function (a, b) {
                var nameA = a.name.toLowerCase();
                var nameB = b.name.toLowerCase();
                if (nameA < nameB) //sort string ascending
                    return -1
            })

Answer 1

cars = [{
        id: 1,
        items: [{
          name: 'ab',
          description: 'this is car1 description'
        },{
          name: 'cd',
          description: 'this is car2 description'
        },{
          name: 'car3',
          description: 'this is car3 description'
        },{
          name: 'aaa',
          description: 'this is car4 description'
        },{
         name: 'car5',
          description: 'this is car5 description'
        }]
   }];

  cars[0].items.sort((a,b) => a.name > b.name ? 1 : -1)
