< mat-stepper> ,一个Angular Directive,用于创建类似工作流程步骤的向导.
在本章中,我们将展示使用Angular Material绘制步进控件所需的配置.
按照以下步骤更新我们创建的Angular应用程序在 Angular 6 - Project Setup 章节 :
Step | 描述 |
---|---|
1 | 创建一个名为 materialApp 的项目,如 Angular 6 - Project中所述设置章节. |
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 {MatStepperModule, MatInputModule, MatButtonModule} from '@angular/material' import {FormsModule, ReactiveFormsModule} from '@angular/forms'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, BrowserAnimationsModule, MatStepperModule, MatInputModule, MatButtonModule, FormsModule, ReactiveFormsModule ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }
以下是修改后的HTML主机文件的内容 app.component.html .
<mat-horizontal-stepper [linear] = "isLinear" #stepper> <mat-step [stepControl] = "firstFormGroup"> <form [formGroup] = "firstFormGroup"> <ng-template matStepLabel>Enter your name</ng-template> <mat-form-field> <input matInput placeholder = "Last name, First name" formControlName = "firstCtrl" required> </mat-form-field> <div> <button mat-button matStepperNext>Next</button> </div> </form> </mat-step> <mat-step [stepControl] = "secondFormGroup"> <form [formGroup] = "secondFormGroup"> <ng-template matStepLabel>Enter your address</ng-template> <mat-form-field> <input matInput placeholder = "Address" formControlName = "secondCtrl" required> </mat-form-field> <div> <button mat-button matStepperPrevious>Back</button> <button mat-button matStepperNext>Next</button> </div> </form> </mat-step> <mat-step> <ng-template matStepLabel>Done</ng-template> Details taken. <div> <button mat-button matStepperPrevious>Back</button> <button mat-button (click) = "stepper.reset()">Reset</button> </div> </mat-step> </mat-horizontal-stepper>
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 { FormGroup } from "@angular/forms"; import { FormBuilder } from "@angular/forms"; import { Validators } from "@angular/forms"; export interface Food { value: string; display: string; } @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'materialApp'; firstFormGroup: FormGroup; secondFormGroup: FormGroup; constructor(private _formBuilder: FormBuilder) {} ngOnInit() { this.firstFormGroup = this._formBuilder.group({ firstCtrl: ['', Validators.required] }); this.secondFormGroup = this._formBuilder.group({ secondCtrl: ['', Validators.required] }); } }
验证结果.
首先,我们使用mat-stepper创建了步进器.
然后,我们使用mat-step添加了内容.
