Question

我陷入了组件和模板之间的表单绑定中。我想为发布方法实现REST API

component.html

  <div class="container custom-container">
    <div class="col-md-12">
      <h3 class="mb-3 text-center">Create Employee</h3>

<div class="form-group">
  <input type="text" [(ngModel)]="employeeDetails.name" class="form-control" placeholder="Name">
</div>

<div class="form-group">
  <input type="text" [(ngModel)]="employeeDetails.email" class="form-control" placeholder="Email">
</div>


<div class="form-group">
  <input type="text" [(ngModel)]="employeeDetails.phone" class="form-control" placeholder="Phone">
</div>

<div class="form-group">
  <button class="btn btn-success btn-lg btn-block" (click)="addEmployee()">Create Employee</button>
</div>

Component.ts

   import { Component, OnInit, Input } from '@angular/core';
   import { Router } from '@angular/router';
   import { RestApiService } from "../shared/rest-api.service";
   @Component({
      selector: 'app-employee-create',
      templateUrl: './employee-create.component.html',
      styleUrls: ['./employee-create.component.css']
   })
  export class EmployeeCreateComponent implements OnInit {

  @Input() employeeDetails = { name: '', email: '', phone: 0 }

  constructor(
     public restApi: RestApiService, 
     public router: Router
  ) { }

  ngOnInit() { }

  addEmployee(dataEmployee) {
      this.restApi.createEmployee(this.employeeDetails).subscribe((data: {}) => {
      this.router.navigate(['/employees-list'])
     })
    }
  }

我想要在createEmployee函数中传递表单值。这样我就可以在服务器端访问它。

Answer 1

您的方法addEmployee不需要任何参数，因为您使用的是模板驱动的方法来绑定表单数据，同时您也没有从html传递任何数据。将您的方法签名更改为addEmployee() { //logic }。单击按钮后，它将触发此方法，并让您将当前值绑定到对象

Answer 2

使用console.log检查表单值，似乎表单值已正确绑定。在传递到http post之前尝试对对象进行字符串化

JSON.stringify(this.employeeDetails)

角7 ngmodel组件和表单绑定
