Question

我正在开发一个有角度的Web应用程序。我需要根据在这些标签的内容中执行的操作来控制我的角度标签。例如，我有以下标签：物品信息，变化，价钱，库存等这些选项卡包含由角度分量加载的表单。当项目信息表单成功提交后，我想自动切换到“变体”选项卡。另外，用户在保存项目信息之前应该不能切换到版本选项卡。

<mat-tab-group class=" navbar-default panel-piluku  nav nav-justified nav-wizard nav-progression" > 
  <mat-tab class="outbound_link" role="button" title="Item Info" label="Item Info">
    <add-product-information></add-product-information>
  </mat-tab>
  <mat-tab class="outbound_link" role="button" title="Variations" label="Variations">
    <add-product-variation></add-product-variation>
  </mat-tab>
  <mat-tab class="outbound_link" role="button" title="Pricing" label="Pricing">
      <add-product-pricing></add-product-pricing>
  </mat-tab>
  <mat-tab class="outbound_link" role="button" title="Inventory" label="Inventory">
      <add-product-stock></add-product-stock>
  </mat-tab>
  <mat-tab class="outbound_link" role="button" title="Images" label="Images">
    <add-product-images></add-product-images>
  </mat-tab>
  <mat-tab class="outbound_link" role="button" title="Locations" label="Locations">
    <add-product-locations></add-product-locations>
  </mat-tab>
</mat-tab-group>

constructor(private route: ActivatedRoute, private productsService: ProductsService, private router: Router, public dialog: MatDialog, private suppliersService: SuppliersService) { }
  submitProduct = function(){
    this.product["sku"] = this.sku;
    this.product["alternate_sku"] = this.alternate_sku;
    this.product["product_name"] = this.product_name;
    this.product["product_description"] = this.product_description;
    this.product["category"] = this.category_id;
    this.product["price_per_unit"] = this.price_per_unit;
    this.product["reorder_level"] = this.reorder_level;
    this.product["discontinued"] = this.discontinued;
    this.product["cost"] = this.cost;
    this.product["default_price"] = this.default_price;
    this.product["best_price"] = this.best_price;
    this.product["medium_price"] = this.medium_price;
    this.product["brand"] = this.brand;
    this.product["upc"] = this.upc;
    this.productsService.addProduct(this.product).subscribe((data)=>{
      ````Here the tab should switch```````
    });

<form action="submitProduct()" id="item_form" class="form-horizontal" method="post" accept-charset="utf-8">

  <input type="hidden" name="ecommerce_product_id" value="" />
...
...
...

      <div class="form-actions">
        <input type="submit" name="submitf" value="Save" id="submitf"
          (click)="submitProduct()" class="submit_button floating-button btn btn-lg btn-primary" />
      </div>
    </div>
  </div>
</form>

一个用户可以控制使用selectIndex输入的mat-tab-group选择的标签。要更改tabSelected，将其设置为所需的标签索引，然后将标签更改为设置的索引。

要做到这一点，我只需定义一个服务并使用行为主体。我的服务定义：

my-tab.service.ts：

@Injectable()

export class MyTabService{
 tabSubject : BehaviorSubject<number> = new BehaviorSubject<number>(0);

 constructor(){}

 setTabSelected(tabIndex : number){
  this.tabSubject.next(tabIndex);
 } 

 getTabSelected() {
  this.tabSubject.asObservable();
 }
}

现在在选项卡组件中订阅getTabSelected()，您将在订阅响应中得到tabIndex。

考虑您的标签组件为my-tab.component.ts，

@Component({...})
export class MyTabComponent {
 selectdIndex : number = 0;
 constructor(private _myTabService : MyTabService){}

 ngOnInit(){

 this.-myTabService.getTabSelected().subscribe((tabIndex : number) =>{
  this.selectedIndex = tabIndex;
 })

...
 }
...
}

在模板中使用selectedIndex：

<mat-tab-group class=" navbar-default panel-piluku  nav nav-justified nav-wizard nav-progression" [selectedIndex]='selectedIndex'> 
  <mat-tab class="outbound_link" role="button" title="Item Info" label="Item Info">
    <add-product-information></add-product-information>
  </mat-tab>
  <mat-tab class="outbound_link" role="button" title="Variations" label="Variations">
    <add-product-variation></add-product-variation>
  </mat-tab>
  <mat-tab class="outbound_link" role="button" title="Pricing" label="Pricing">
      <add-product-pricing></add-product-pricing>
  </mat-tab>
  <mat-tab class="outbound_link" role="button" title="Inventory" label="Inventory">
      <add-product-stock></add-product-stock>
  </mat-tab>
  <mat-tab class="outbound_link" role="button" title="Images" label="Images">
    <add-product-images></add-product-images>
  </mat-tab>
  <mat-tab class="outbound_link" role="button" title="Locations" label="Locations">
    <add-product-locations></add-product-locations>
  </mat-tab>
</mat-tab-group>

有关垫子选项卡组中的输入和事件的更多信息，请参考：Mat Tab

是否有一种方法可以根据这些选项卡的内容基于表单提交在角度材料选项卡之间进行切换？
