                    <p class="lead text-center" *ngIf="f.valid">
                        Proceed below if details above is correct.

                </div>
            </div>
        </div>
    </div>
</form>

然而..

我立即ng build --prod,我收到此错误:

它抱怨的究竟是什么样的错误?为什么现在抱怨,但不是在我运行ng serve

修改

这是我的AppComponent

import { Component } from '@angular/core';
import { NgForm } from '@angular/forms';
import { PurchaseService } from './purchase.service';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  busy: boolean;

  constructor(public purchase: PurchaseService) {}

  onSubmit(data) {
    console.log(data);
  };
}

在此行中,您尝试绑定到名为name

的变量
<input type="text" class="form-control" id="customerName" aria-describedby="emailHelp" placeholder="e.g Pantang Francias"
        name="name" [(ngModel)]="name">

组件中没有name变量,因此出错。

我通过在实现OnInit的TS文件类中声明[(ngModel)]的属性来获得它。

HTML文件

 <input type="text" 
        class="form-control"
        id="customerName"
        aria-describedby="emailHelp"
        placeholder="e.g Pantang Francias"
        name="name" 
        [(ngModel)]="name_test">

TS文件

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  name_test: String = "";
}

只需专注于name_test,您就会得到答案。

学习愉快!

在app.component.html中,您创建了带有输入字段的表单,并且声明了用于绑定输入字段数据的模型。

<input type="text" class="form-control" id="customerName" aria-describedby="emailHelp" placeholder="e.g Pantang Francias"
        name="name" [(ngModel)]="name">

<select class="form-control" name="network" id="network" aria-describeby="networkHelp" [(ngModel)]="network" required>

<input type="number" name="phone_number" class="form-control" id="phone_number" placeholder="e.g 0269201707" aria-describeby="phone_numberHelp"
        [(ngModel)]="phone_number" required maxlength="10">

这些型号-名称,网络,电话号码需要添加到app.component.ts中。

最近遇到了同样的问题,所以也许这对你有帮助。

  1. FormsModule 添加到您的 app.modules.ts
import { FormsModule } from '@angular/forms';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
....
    FormsModule
  ],
...
})
  1. 通过添加在 ts 文件中声明这些变量 name!: string;network!: any;
  2. 的其他类型

答案 4 :(得分:0)

很明显,我们可以看到,您还没有在 AppComponent 文件中声明变量 name、network、phone_number 等。
