javascript - 角反应形式日期设定值

问题描述

我正在开发 Angular 项目，其中一个组件是更新客户端组件，其中客户端的数据被填充到响应式表单以进行编辑，客户端的信息来自 API，
我使用 FormGroup.setvalue 将数据填充到表单中，除日期输入字段外，所有客户的数据均已填充，请您告知为什么日期输入字段未填充任何内容，请考虑所有这些信息将在编辑后重新提交，

import { Component, OnInit } from '@angular/core';
import { ActivatedRoute, Router } from '@angular/router';
import { UserService } from 'src/app/services/user.service';
import { Client } from 'src/app/models/Client';
import { FormGroup, FormBuilder, FormControl } from '@angular/forms';


@Component({
 selector: 'app-update',
 templateUrl: './update.component.html',
 styleUrls: ['./update.component.css']
 })
 export class UpdateComponent implements OnInit {

client:Client= new Client();
editForm: FormGroup;

constructor(private route:ActivatedRoute, private service:UserService, private router:Router,        private formBuilder:FormBuilder) { }


ngOnInit() {

 this.editForm = new FormGroup({
  id: new FormControl(),
  domain: new FormControl(),
  owner : new FormControl(),
  email: new FormControl(),
  hostComp : new FormControl(),
  cpUrl: new FormControl(),
  expDate: new FormControl(),
  cpUsername : new FormControl(),
  cpPassword : new FormControl(),
  depDate : new FormControl(),
  notices: new FormControl() 
 });



  this.route.params.subscribe(data=>{
  const id = data.id;


     this.service.getClient(id).subscribe(data=>{

     this.editForm.setValue({
      id: data.id,
      domain: data.domain,
      owner : data.owner,
      email: data.email,
      hostComp : data.hostComp,
      cpUrl: data.cpUrl,
      expDate: data.expDate,
      cpUsername : data.cpUsername,
      cpPassword : data.cpPassword,
      depDate : data.depDate,
      notices: data.notices 
    })     
    });
   });
  }

  cancel(){
 let id = this.client.id
 this.router.navigate(['/info', id]);
  }

  update(){

  this.service.updateClient(this.client).subscribe(data=>{
    this.router.navigate(['/info', this.client.id]);
  });
  }
   }

html视图是这样的

<form  [formGroup]="editForm" (ngSubmit)="update()">


    <label>Domain</label>
   <input type="text"  formControlName="domain" name="domain" >

   <label>Owner</label>
    <input type="text"  name="owner" formControlName="owner" >


   <label>Email</label>
    <input type="text"  name="email" formControlName="email" >

   <label>Hosting Company</label>
   <input type="text"  name="hostcomp" formControlName="hostComp" >

     <label>CP URL</label>
   <input type="text"  name="cpurl" formControlName="cpUrl" >

    <label>Expiration</label>
    <input type="date"  name="expdate" formControlName="expDate" >

    <label>Deployment</label>
    <input type="date"  name="depdate" formControlName="depDate" >

     <button type="submit" class="btn btn-success">Submit</button>
     <button type="submit" class="btn btn-primary" (click)="cancel()">Cancel</button>

   </form>

解决方案

可能是因为不同data types。可能您date的来源api是 instring并且您正在尝试设置输入类型的值date

你可以试试这个

this.editForm.setValue({
  id: data.id,
  domain: data.domain,
  owner : data.owner,
  email: data.email,
  hostComp : data.hostComp,
  cpUrl: data.cpUrl,
  expDate: new Date(data.expDate),
  cpUsername : data.cpUsername,
  cpPassword : data.cpPassword,
  depDate : new Date(data.depDate),
  notices: data.notices 
})
