Question

我正在尝试使进度条成角度。我开始使用角度mmat-stepper，我的代码如下：

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 { }

我的html页面：

<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>

我的组件如下：

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]
      });
   }
}

我得到的输出是这样的：

output_image

但是我要使进度条如下图所示

desired_output

如何制作进度条，如期望的输出图像所示？

Answer 1

您可以通过修改材料设计中的选择器（.mat-stepper-horizontal-line）来实现。

将此添加到您的主要样式。（根据期望的输出更改css）

.mat-stepper-horizontal-line {
    border: solid black;
    border-width: 0 3px 3px 0;
    display: inline-block;
    padding: 3px;
    transform: rotate(-45deg);
    -webkit-transform: rotate(-45deg);
}

样本输出
