TypeError: no se puede crear la propiedad 'validator' en la cadena 'abc@gmail.com' en setUpControl

Enfrenta problema en formGroup . Primero basado en URL Tomo un valor y llamo a API para recuperar datos de usuario particulares para text de campo previo.

register.html

 <form [formGroup]="form" (ngSubmit)="onSubmit(form.value)" class="form-horizontal"> <div class="form-group row"> <label for="inputEmail3" class="col-sm-4 ">Username</label> <div class="col-sm-8"> <input [formControl]="email" type="text" class="form-control" id="inputEmail3" placeholder="Email Address" [readonly]="isReadOnly"> </div> </div> </form> 

register.component.ts

 import { Component } from '@angular/core'; import { FormGroup, AbstractControl, FormBuilder, Validators } from '@angular/forms'; import { Router, ActivatedRoute } from '@angular/router'; import { EmailValidator, EqualPasswordsValidator } from '../../theme/validators'; @Component({ selector: 'register', templateUrl: './register.html', }) export class Register { public form: FormGroup; public email: AbstractControl; public username: string; constructor(private registerService: RegisterService, fb: FormBuilder, private router: Router, private route: ActivatedRoute) { this.form = fb.group({ 'email': ['', Validators.compose([Validators.requinetworking])] .... etc.. }); this.email = this.form.controls['email']; this.registerService.getUser({ userId: "asdasd2123da2das" }).subscribe(posts => { if (posts) { var userObj = posts.json(); console.log("userObj : ", userObj.data); if (userObj.data && userObj.data[0].email) { this.email = this.username = userObj.data[0].email; // ouput : abc@gmail.com this.isReadOnly = true; this.router.navigateByUrl('/register'); } else { alert("You are Not Autorize to access this Page"); this.router.navigateByUrl('/login'); } } }); } } 

Error de detalles :

intente de esta manera cambiar [formControl] a formControlName .

Y para establecer la salida en el campo de input, haga lo siguiente, señale la línea this.form.patchValue

 import { Component } from '@angular/core'; import { FormGroup, AbstractControl, FormBuilder, Validators } from '@angular/forms'; import { Router, ActivatedRoute } from '@angular/router'; import { EmailValidator, EqualPasswordsValidator } from '../../theme/validators'; @Component({ selector: 'register', templateUrl: './register.html', }) export class Register { public form: FormGroup; public email: AbstractControl; public username: string; constructor(private registerService: RegisterService, fb: FormBuilder, private router: Router, private route: ActivatedRoute) { this.form = fb.group({ 'email': ['', Validators.compose([Validators.requinetworking])] .... etc.. }); this.email = this.form.controls['email']; this.registerService.getUser({ userId: "asdasd2123da2das" }).subscribe(posts => { if (posts) { var userObj = posts.json(); console.log("userObj : ", userObj.data); if (userObj.data && userObj.data[0].email) { this.email = this.username = userObj.data[0].email; // ouput : abc@gmail.com this.form.patchValue({ email : this.email }); this.isReadOnly = true; this.router.navigateByUrl('/register'); } else { alert("You are Not Autorize to access this Page"); this.router.navigateByUrl('/login'); } } });
