转到特定路线的div元素 [英] Go to particular Route's div element

问题描述

我有两条路线.从一条路线中，我需要通过单击按钮来获取另一条路线的div元素.我对id(#)的处理方式与我们在HTML中所做的类似，但无法解决.您能建议在Angular中做一个最好的方法吗?

I have two routes. From one route I need to get another route's div element by button click. I done a similar way with id(#) that we do in HTML but It's not working out. Can you suggest a best way to do in Angular>

路线一(/route1)

<div class="div1">
<p>hi</p>
</div>

<div class="div2">
<p>hello</p>
</div>

第二条路线(/route2)

<button (click)="getDiv()"></button>

TS

getDiv()
{
      this.router.navigate(['/route1']); // I need to get div1 of route1 here
}

推荐答案

如果您使用的是Angular 6.1+版本，则可以手动启用anchorScrolling

If you are using angular 6.1+ version you can enable anchorScrolling manually

app.module.ts

@NgModule({
  imports:      [ BrowserModule, FormsModule, RouterModule.forRoot(route,{
       anchorScrolling: 'enabled'
  }) ],
  declarations: [ AppComponent],
  bootstrap:    [ AppComponent ]
})

然后在您要滚动到的div上指定ID

Then specifies the id on the div which you want to scroll to

router-a.component.ts

<div class="div1"  id="div1">
<p>Div1</p>
</div>

<div class="div2" id="div2" >
<p>Div2</p>
</div>

Finall使用片段导航到当前div位置

Finall Use fragment to navigate to the current div location

getDiv() {
    this.router.navigate(['/route2'], { fragment: 'div2' });
  }
