Question

我正在使用Angular Material v6。每当单击mat-table中的一行时，我都想添加波纹效果。

HTML：

<table mat-table [dataSource]="this.projectsList" class="mat-elevation-z8">

  <ng-container matColumnDef="id">
    <th mat-header-cell *matHeaderCellDef>ID</th>
    <td mat-cell *matCellDef="let project">{{project.id}}</td>
  </ng-container>

  <ng-container matColumnDef="title">
    <th mat-header-cell *matHeaderCellDef>Title</th>
    <td mat-cell *matCellDef="let project">{{project.title}}</td>
  </ng-container>

  <tr mat-header-row *matHeaderRowDef="this.displayColumns"></tr>
  <tr mat-row *matRowDef="let row; columns: this.displayColumns"></tr>

</table>

SCSS：

table {
  width: 90vw;
  margin-top: 1%;
  margin-left: auto;
  margin-right: auto;
}

.mat-row:hover {
  background: rgba(0, 0, 0, 0.04);
}

模块导入：

AppRoutingModule,
BrowserModule,
BrowserAnimationsModule,
MatToolbarModule,
MatSidenavModule,
MatButtonModule,
MatCheckboxModule

自定义主题：

@import '~@angular/material/theming';
@import './palette.scss';
// Plus imports for other components in your app.

// Include the common styles for Angular Material. We include this here so that you only
// have to load a single css file for Angular Material in your app.
// **Be sure that you only ever include this mixin once!**
@include mat-core();

// Define the default theme (same as the example above).
$light-primary-blue:    mat-palette($primary-blue);
$light-accent-purple:   mat-palette($accent-purple);
$light-theme:           mat-light-theme($light-primary-blue, $light-accent-purple);

// Include the default theme styles.
@include angular-material-theme($light-theme);

// Define an alternate dark theme.
$dark-primary: mat-palette($primary-blue);
$dark-accent:  mat-palette($accent-purple);
$dark-theme:   mat-dark-theme($dark-primary, $dark-accent);

// Include the alternative theme styles inside of a block with a CSS class. You can make this
// CSS class whatever you want. In this example, any component inside of an element with
// `.dark` will be affected by this alternate dark theme instead of the default theme.
.dark {
  @include angular-material-theme($dark-theme);
}

我找不到任何有关在表上添加波纹效果的文档，但是我看到了几个Stackblitz实例，它们在行单击时具有波纹效果。我试图复制他们正在做的事情，但没有成功。

Answer 1

如下修改您的td元素。

<table mat-table [dataSource]="this.projectsList" class="mat-elevation-z8">

  <ng-container matColumnDef="title">
    <th mat-header-cell *matHeaderCellDef>Title</th>
    <td mat-cell *matCellDef="let project">
      <div class='mat-ripple-wrapper' matRipple>
        {{project.title}}
      </div> 
    </td>
  </ng-container>

</table>

样式

.mat-ripple-wrapper{
   position: relative;
}

单击触发器元素后，mat-ripple指令将创建一个div，如果将其放置在一行上，它将使其不适合放置。最好的办法是将td数据包装在div中，然后在该div上添加指令以包含动态生成的div。

您可以尝试使用此代码

 /deep/.mat-row:hover {
  background: rgba(0, 0, 0, 0.04);
 }

对于波纹效果，请尝试

.ripple {
  background-position: center;
  transition: background 0.8s;
}
.ripple:hover {
  background: #47a7f5 radial-gradient(circle, transparent 1%, #47a7f5 1%) center/15000%;
}
.ripple:active {
  background-color: #6eb9f7;
  background-size: 100%;
  transition: background 0s;
}

行单击时将“角形材料波纹”效果添加到“垫表”
