< mat-radiobutton> ,Angular Directive,用于< input type ="radio">用于增强基于样式的材料设计..
在本章中,我们将展示使用Angular Material绘制单选按钮控件所需的配置.
按照以下步骤更新我们在 Angular 6 - 项目设置章节中创建的Angular应用程序;
Step | 描述 |
---|---|
1 | 创建一个名为 materialApp 的项目,如 Angular 6 - Project Setup 章节中所述. |
2 | 修改 app.module.ts , app.component. ts , app.component.css 和 app.component.html ,如下所述.保持其余文件不变. |
3 | 编译并运行应用程序以验证实现的逻辑的结果. |
以下是修改后的模块描述符的内容 app.module.ts .
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import {BrowserAnimationsModule} from '@angular/platform-browser/animations'; import {MatRadioModule} from '@angular/material' import {FormsModule, ReactiveFormsModule} from '@angular/forms'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, BrowserAnimationsModule, MatRadioModule, FormsModule, ReactiveFormsModule ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }
以下是修改过的CSS文件的内容 app.component.css .
.tp-radio-group { display: inline-flex; flex-direction: column; } .tp-radio-button { margin: 5px; } .tp-selected-value { margin: 15px 0; }
以下是修改过的ts文件的内容 app.component.ts .
import { Component } from '@angular/core'; import { FormControl } from "@angular/forms"; import { Validators } from "@angular/forms"; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'materialApp'; favoriteSeason: string; seasons: string[] = ['Winter', 'Spring', 'Summer', 'Autumn']; }
以下是修改过的HTML主机文件的内容 app.component.html .
<mat-radio-group class = "tp-radio-group" [(ngModel)] = "favoriteSeason"> <mat-radio-button class = "tp-radio-button" *ngFor = "let season of seasons" [value] = "season"> {{season}} </mat-radio-button> </mat-radio-group> <div class = "tp-selected-value"> Selected Season: {{favoriteSeason}} </div>
验证结果.
首先,我们使用与ngModel绑定的mat-radio-group创建了一个单选按钮组.
然后,我们使用mat添加了单选按钮-radio-button.
