Angular2验证错误为'ngClass',因为它不是'div'的已知属性.(

Question

在这里我为EName验证编写了一个小的验证属性,当我尝试2加载Html页面时,我将错误视为'ngClass',因为它不是'div'的已知属性.(

Component.ts

import { Component, OnInit } from "@angular/core"
import { Employee } from "../../../templates/employee/employee"
import { Validators, FormGroup, FormBuilder } from "@angular/forms"
@Component({
    selector: "customer-ui",
    templateUrl: "../../../templates/customer/customer.html"
})
export class JamComponent implements OnInit {
    EmpleoyeeForm: FormGroup;
    public constructor(private fb: FormBuilder) {}
    ngOnInit(): void {
        this.EmpleoyeeForm = this.fb.group({
            EmpName: ['', [Validators.required]]

        })
    }

Htmlcode

<form class="form-horizontal" novalidate [formGroup]="EmpleoyeeForm">

    <fieldset>
        <div class="form-group" [ngClass]="{'has-error': (EmpleoyeeForm.get('EmpName').touched ||
                                                  EmpleoyeeForm.get('EmpName').dirty) &&
                                                    !EmpleoyeeForm.get('EmpName').valid }">

            <label for="name">Name</label>
            <input type="text" class="form-control" formControlName="EmpName" [(ngModel)]="EmpName" />

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

Answer 1

您需要添加BrowserModule

@NgModule(
  imports: [BrowserModule, /* other imports */],
  ...
)

如果是在子模块中导入CommonModule.

import { CommonModule } from "@angular/common"

Answer 2

如果您已经拥有 CommonModule/BrowserModule 并且它仍然无法工作，还要确保您正确键入了该属性。我有ngclass而不是ngClass（注意'C'）。
