我是Angular 2的初学者，我正在try 在组件中获取textbox的值，但我真的不知道如何获取它.
HTML :
<form [formGroup]="regForm" >
<label for="txtFName">First Name</label>
<input type="text" id="txtFName"/>
</form>
component.ts :
import { Component } from "@angular/core"
import { FormControl, FormGroup, FormBuilder, Validator, Validators,ReactiveFormsModule } from "@angular/forms";
import { customer } from '../model/customerModel'
import { Router } from "@angular/router";
export class regComponent
{
private Customer:customer;
private regForm:FormGroup;
private firstName:FormControl;
constructor (private formBuilder:FormBuilder,private router:Router)
{
this.firstName=new FormControl('',[Validators.required])
this.regForm=formBuilder.group({
firstName:this.firstName
})
console.log(this.regForm.value);
}
这里我在控制台中得到空值.请在这方面提供帮助
