Question

我想让一个子元素触发它自己的点击，并且不要回复它有[routerLink]的父元素，问题是子元素可以＆＃39;在delete()中运行(click)="delete()"函数，只需跟随[routerLink]中的父项（它导航到/ product /：id）

    <div class="item">

<!-- parent element -->
    <a [routerLink]="['/product/'+product.id]">
        <div class="figure">
          <div class="sides">
            <div class="side">
              <div class="card">
<img class="img" [src]="product.thumb"> 
                <div class="content">
                  <div class="header">{{product.name}}</div>
                  <div class="meta"> <span>product.category</span> </div>
                </div>
                <div class="extraContent"> <span class="ui right floated black">

                <!-- child element -->
                <a (click)="delete()" ><i class="red trash outline icon"></i></a></span> <span><i class="deleteProductIcon"></i></span> </div> 
                <!-- child element -->

              </div>
            </div>
          </div>
        </div>
      </a>
<!-- parent element -->

</div>

我尝试将[routerLink]移到上方div，但它仍然采取相同的行为

Answer 1

在您的情况下，仅指定stopPropagation的孩子有时可能无效。特别是当孩子和父母都有他们独立的＆＃34; routerLinks＆＃34;定义

我建议使用＆＃34;导航＆＃34;处理路由。组件中的方法并返回＆＃34; false＆＃34;到底。这将阻止父路由在完成子项的单击处理程序后触发。

// pass in the event object to the delete function
<a (click)="delete($event)" ><i class="red trash outline icon"></i></a>

// in the delete function, stop event propagation
delete(event){
    event.stopPropagation();
    this.route.navigate(['child/route/here']);
    return false;
}

从点击处理程序返回false会阻止父路由为我工作。

如果你在delete function（）中停止播放，那么事件将不会通过routerLink冒泡到锚标记

// pass in the event object to the delete function
<a (click)="delete($event)" ><i class="red trash outline icon"></i></a>

// in the delete function, stop event propagation
delete(event){
    event.stopPropagation();
}

Answer 3

仅event.stopPropagation();对我不起作用。我要做的就是也加入e.preventDefault();

// In your HTML   
<a [routerLink]="['/product/'+product.id]">
     <!-- your other inner stuff -->
     <a (click)="delete($event)" ><i class="red trash outline icon"></i></a>
</a>

// In your component
delete(e){
    e.stopPropagation();
    e.preventDefault();
}

如何不在子元素上应用[routerLink]？
