Angular 4 Material 表高亮显示一行 [英] Angular 4 Material table highlight a row

问题描述

我正在寻找一种在 md-table 中突出显示整行的好方法.
我应该做指令还是什么?

<md-table #table [dataSource]=dataSource"><!--- 请注意，这些列可以按任何顺序定义.实际呈现的列被设置为行定义"的属性.--><!-- ID 列--><ng-container cdkColumnDef=userId"><md-header-cell *cdkHeaderCellDef>ID</md-header-cell><md-cell *cdkCellDef=让行">{{row.id}} </ng-容器><!-- 进度栏--><ng-container cdkColumnDef="progress"><md-header-cell *cdkHeaderCellDef>进度 </md-header-cell><md-cell *cdkCellDef=让行">{{row.progress}}% </ng-容器><!-- 名称列--><ng-container cdkColumnDef="userName"><md-header-cell *cdkHeaderCellDef>名称</md-header-cell><md-cell *cdkCellDef=让行">{{row.name}} </ng-容器><!-- 颜色列--><ng-container cdkColumnDef=颜色"><md-header-cell *cdkHeaderCellDef>颜色</md-header-cell><md-cell *cdkCellDef=让行"[style.color]=row.color">{{row.color}} </md-cell></ng-容器><md-header-row *cdkHeaderRowDef=displayedColumns"></md-header-row><md-row *cdkRowDef="let row;列:displayedColumns;"></md-row></md-table>

解决方案

更新材料版本 (md --> mat):

html:

<!-- 添加点击事件传递选中的行索引--><mat-row *cdkRowDef="let row;列:displayColumns;"[ngClass]="{'highlight': selectedRowIndex == row.id}";(点击)=突出显示(行)"></mat-row>

原答案:

您可以通过使用 ngClass 和像 selectedRowIndex 这样的标志来实现.每当单击的行索引等于 selectedRowIndex 时，将应用该类.

Plunker 演示

html:

<!-- 添加点击事件传递选中的行索引--><md-row *cdkRowDef="let row;列:displayColumns;"[ngClass]="{'highlight': selectedRowIndex == row.id}";(点击)=突出显示(行)"></md-row>

CSS:

.highlight{背景:#42A948；/* 绿色 */}

ts:

selectedRowIndex = -1;突出显示(行){this.selectedRowIndex = row.id;}

I'm looking for a good way to highlight the whole a row in md-table.
Should I do directive or what?

<div class="example-container mat-elevation-z8">
  <md-table #table [dataSource]="dataSource">

    <!--- Note that these columns can be defined in any order.
          The actual rendered columns are set as a property on the row definition" -->

    <!-- ID Column -->
    <ng-container cdkColumnDef="userId">
      <md-header-cell *cdkHeaderCellDef> ID </md-header-cell>
      <md-cell *cdkCellDef="let row"> {{row.id}} </md-cell>
    </ng-container>

    <!-- Progress Column -->
    <ng-container cdkColumnDef="progress">
      <md-header-cell *cdkHeaderCellDef> Progress </md-header-cell>
      <md-cell *cdkCellDef="let row"> {{row.progress}}% </md-cell>
    </ng-container>

    <!-- Name Column -->
    <ng-container cdkColumnDef="userName">
      <md-header-cell *cdkHeaderCellDef> Name </md-header-cell>
      <md-cell *cdkCellDef="let row"> {{row.name}} </md-cell>
    </ng-container>

    <!-- Color Column -->
    <ng-container cdkColumnDef="color">
      <md-header-cell *cdkHeaderCellDef>Color</md-header-cell>
      <md-cell *cdkCellDef="let row" [style.color]="row.color"> {{row.color}} </md-cell>
    </ng-container>

    <md-header-row *cdkHeaderRowDef="displayedColumns"></md-header-row>
    <md-row *cdkRowDef="let row; columns: displayedColumns;"></md-row>
  </md-table>
</div>

解决方案

Update for Newer Material Version (md --> mat):

html:

<!-- Add the highlight class in row definiton of md-table -->
<!-- Add click event to pass the selected row index -->

<mat-row *cdkRowDef="let row; columns: displayedColumns;" 
         [ngClass]="{'highlight': selectedRowIndex == row.id}"
         (click)="highlight(row)">
</mat-row>

Original Answer:

You can do it by using ngClass and a flag like selectedRowIndex. Whenever clicked row index is equal to selectedRowIndex, the class will be applied.

Plunker demo

html:

<!-- Add the highlight class in row definiton of md-table -->
<!-- Add click event to pass the selected row index -->

<md-row *cdkRowDef="let row; columns: displayedColumns;" 
         [ngClass]="{'highlight': selectedRowIndex == row.id}"
         (click)="highlight(row)">
</md-row>

css:

.highlight{
  background: #42A948; /* green */
}

ts:

selectedRowIndex = -1;

highlight(row){
    this.selectedRowIndex = row.id;
}
