Angular Material 7 进度条
<mat-progress-bar>用于显示带有Material样式的进度条。
在本章中,我们将展示使用Angular Material绘制确定性进度条和非确定性进度条所需的配置。
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 {MatProgressBarModule, MatRadioModule, MatSliderModule} from '@angular/material' import {FormsModule, ReactiveFormsModule} from '@angular/forms'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, BrowserAnimationsModule, MatProgressBarModule, 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-button class = "tp-margin" value = "buffer"> Buffer </mat-radio-button> <mat-radio-button class = "tp-margin" value = "query"> Query </mat-radio-button> </mat-radio-group> </section> <section class = "tp-section" *ngIf = "mode === 'determinate' || mode === 'buffer'"> <label class = "tp-margin">Progress:</label> <mat-slider class = "tp-margin" [(ngModel)] = "value"></mat-slider> </section> <section class = "tp-section" *ngIf = "mode === 'buffer'"> <label class = "tp-margin">Buffer:</label> <mat-slider class = "tp-margin" [(ngModel)] = "bufferValue"></mat-slider> </section> <section class = "tp-section"> <label class = "tp-margin">Mode: {{mode}}</label> <mat-progress-bar class = "tp-margin" [color] = "color" [mode] = "mode" [value] = "value" [bufferValue] = "bufferValue" > </mat-progress-bar> </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; bufferValue = 75; }
结果
细节
这里,我们使用mat-progress-bar创建了进度条。
