我试图显示在文本框中输入的值，但收到“错误 TypeError：无法读取未定义的属性‘值’”错误。
这是我在组件中注册的 formControls：
import { Component } from '@angular/core';
import { FormGroup, FormControl, Validators } from '@angular/forms';
@Component({
selector: 'app-site-reset',
templateUrl: './site-reset.component.html',
styleUrls: ['./site-reset.component.scss']
})
export class SiteResetComponent {
siteResetForm = new FormGroup({
attuid: new FormControl(''),
contactNumber: new FormControl(''),
vendor: new FormControl(''),
severity: new FormControl(''),
siteNum: new FormControl(''),
reasonSelect: new FormControl(''),
other: new FormControl(''),
pilot: new FormControl(''),
alarms: new FormControl(''),
adjacent: new FormControl(''),
reset: new FormControl(''),
anr: new FormControl(''),
tickets: new FormControl(''),
other_action: new FormControl(''),
date: new FormControl(''),
}); …
