Angular Material 7 进度微调器
<mat-progress-spinner>用于显示带有Material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。
创建 Angular 应用
按照以下步骤创建应用程序
1.创建一个名为materialApp的项目。
2.修改app.module.ts, app.component.ts, app.component.css and app.component.htmls。保持其余文件不变。
3.编译并运行程序。
下面是修改后的app.module.ts文件内容。
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 { }下面是修改后的app.component.css文件内容。
.tp-section {
display: flex;
align-content: center;
align-items: center;
height: 60px;
}
.tp-margin {
margin: 0 10px;
}下面是修改后的app.component.html文件内容。
<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>下面是修改后的app.component.ts文件内容。
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;
}结果

细节
这里,我们使用mat-progress-spinner创建了进度微调器。
