< mat-progress-spinner> ,一个Angular Directive,用于显示具有材质样式的进度微调器.
在本章中,我们将展示使用Angular Material绘制确定性和不确定性进度微调器所需的配置.
按照以下步骤操作更新我们在 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. |
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 {MatProgressSpinnerModule, MatRadioModule, MatSliderModule} from '@angular/material' import {FormsModule, ReactiveFormsModule} from '@angular/forms'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, BrowserAnimationsModule, MatProgressSpinnerModule, MatRadioModule, MatSliderModule, FormsModule, ReactiveFormsModule ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }
以下是修改后的ts文件的内容 app.component.css .
.tp-section { display: flex; align-content: center; align-items: center; height: 60px; } .tp-margin { margin: 0 10px; }
以下是修改过的HTML主机文件的内容 app.component.html .
<section class = "tp-section"> <label class = "tp-margin">Color:</label> <mat-radio-group [(ngModel)] = "color"> <mat-radio-button class = "tp-margin" value = "primary"> Primary </mat-radio-button> <mat-radio-button class = "tp-margin" value = "accent"> Accent </mat-radio-button> <mat-radio-button class = "tp-margin" value = "warn"> Warn </mat-radio-button> </mat-radio-group> </section> <section class = "tp-section"> <label class = "tp-margin">Mode:</label> <mat-radio-group [(ngModel)] = "mode"> <mat-radio-button class = "tp-margin" value = "determinate"> Determinate </mat-radio-button> <mat-radio-button class = "tp-margin" value = "indeterminate"> Indeterminate </mat-radio-button> </mat-radio-group> </section> <section class = "tp-section" *ngIf = "mode === 'determinate'"> <label class = "tp-margin">Progress:</label> <mat-slider class = "tp-margin" [(ngModel)] = "value"></mat-slider> </section> <section class = "tp-section"> <label class = "tp-margin">Mode: {{mode}}</label> <mat-progress-spinner class = "tp-margin" [color] = "color" [mode] = "mode" [value] = "value"> </mat-progress-spinner> </section>
以下是修改过的ts文件的内容 app.component.ts .
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'materialApp'; color = 'primary'; mode = 'determinate'; value = 50; }
验证结果.
在这里,我们使用mat-progress-spinner创建了进度微调器.
