Angular Material 2 Table Mat Row Click 事件也通过在 Mat Cell 中单击按钮调用

Question

我是 material 2 的新手，我已经实现了 mat table，其中我在行上单击事件以打开对话框，最后一列中还有一个菜单按钮 "Action" 但在单击按钮时它也会打开对话框而不是打开菜单。

Table

    <mat-table #table [dataSource]="dataSource" matSort  (matSortChange)="sortData($event)">
    <ng-container matColumnDef="id">
          <mat-header-cell *matHeaderCellDef > No. </mat-header-cell>
          <mat-cell *matCellDef="let element"> 
              <mat-checkbox checked='true'></mat-checkbox>
          </mat-cell>
    </ng-container>
    <ng-container matColumnDef="unit_num">
        <mat-header-cell *matHeaderCellDef  mat-sort-header="unit_num"> Unit No. </mat-header-cell>
        <mat-cell *matCellDef="let element"> {{element.unit_num}} </mat-cell>
    </ng-container>
    <ng-container matColumnDef="unit_type">
        <mat-header-cell *matHeaderCellDef mat-sort-header="unit_type"> Unit Type </mat-header-cell>
        <mat-cell *matCellDef="let element"> {{element.unit_type}} </mat-cell>
    </ng-container>
    <ng-container matColumnDef="shares">
        <mat-header-cell *matHeaderCellDef mat-sort-header="shares"> Shares </mat-header-cell>
        <mat-cell *matCellDef="let element"> {{element.shares}} </mat-cell>
      </ng-container>
    <ng-container matColumnDef="sections">
        <mat-header-cell *matHeaderCellDef>Section </mat-header-cell>
        <mat-cell *matCellDef="let element"> {{element.sections.section_type}} </mat-cell>
    </ng-container>
    <ng-container matColumnDef="buildings">
        <mat-header-cell *matHeaderCellDef >Building </mat-header-cell>
        <mat-cell *matCellDef="let element"> {{element.buildings.buildingname}} </mat-cell>
    </ng-container>
    <ng-container matColumnDef="_id">
        <mat-header-cell *matHeaderCellDef> Action </mat-header-cell>
        <mat-cell *matCellDef="let element"> 
          <button mat-button [matMenuTriggerFor]="menu"><mat-icon>more_vert</mat-icon>
          </button>
            <mat-menu #menu="matMenu">
              <button mat-menu-item (click)="edit(element._id)">Edit</button>
              <button mat-menu-item (click)="gotoFamily(element)">Go to current family</button>
              <button mat-menu-item (click)="createNewFam(element)">Create new family</button>
              <button mat-menu-item (click)="openDeleteDialog(element._id)">Delete</button>              
            </mat-menu>
        </mat-cell>
    </ng-container>
    <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
    <mat-row *matRowDef="let row; columns: displayedColumns; let index=index;" mat-ripple style="position:relative;" (click)="edit(row._id,$event)"></mat-row>
    </mat-table>
  <mat-paginator [length]="count"
    [pageSize]="pageSize"
    [pageSizeOptions]="pageSizeOptions"
    (page)="pageSide($event)">
  </mat-paginator>

实际上应该只打开菜单

Answer 1

我刚刚遇到了同样的问题，并使用 Will 对原始 post 的评论解决了它，将带有 $event.stopPropagation 的点击处理程序添加到单元格作为按钮的直接父级。我会把它作为解决方案添加到这里，以防其他人来这里寻找相同的答案。

我有一个 Material 数据 table，其中该行有一个点击事件，可以让您进入编辑模式，最后一列包含一个带有删除操作的按钮。显然你不想同时触发删除和编辑！

这是我用来解决问题的结构：

片段

// Row definition containing a click event
<mat-row *matRowDef="let row; columns: displayedColumns;" (click)="onEdit(row.id)"></mat-row>

// Definition for the cell containing the button
<ng-container matColumnDef="buttons">
    <mat-header-cell *matHeaderCellDef></mat-header-cell>
    <mat-cell *matCellDef="let group" (click)="$event.stopPropagation()">
        <button mat-button (click)="onDelete(group.id)">
            <mat-icon>delete</mat-icon>
        </button>
    </mat-cell>
</ng-container>

完整Table代码

<mat-table #table [dataSource]="dataSource" matSort>
    <ng-container matColumnDef="name">
        <mat-header-cell *matHeaderCellDef mat-sort-header>Name</mat-header-cell>
        <mat-cell *matCellDef="let group">{{ group.name }}</mat-cell>
    </ng-container>
    <ng-container matColumnDef="description">
        <mat-header-cell *matHeaderCellDef>Description</mat-header-cell>
        <mat-cell *matCellDef="let group">{{ group.description }}</mat-cell>
    </ng-container>
    <ng-container matColumnDef="buttons">
        <mat-header-cell *matHeaderCellDef></mat-header-cell>
        <mat-cell *matCellDef="let group" (click)="$event.stopPropagation()">
            <button mat-button (click)="onDelete(group.id)">
                <mat-icon>delete</mat-icon>
            </button>
        </mat-cell>
    </ng-container>

    <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
    <mat-row *matRowDef="let row; columns: displayedColumns;" (click)="onEdit(row.id)"></mat-row>
</mat-table>

再次感谢 Will Howell 的解决方案。

Answer 2

我认为当前接受的答案有缺陷。上述解决方案使部分行不可点击。为了保持整行可点击，您可以将 $event 传递给 html 中的组件并从组件调用 stoppropogation:

html:

<mat-cell *matCellDef="let element" class="rightalign">
    <button mat-raised-button color="primary" (click)="openDialog(element, $event)"><mat-icon>edit</mat-icon> Breyta</button>
  </mat-cell>

组件：

openDialog(data, event): void {
event.stopPropagation();
const editDialogRef = this.dialog.open(EditClientComponent, {
  data: data
});

}
