已经针对此错误发布了一些博客,但没有为FormGroup指定任何博客,他们都使用FormArray提供解决方案
出于某种目的,我必须在角度4中创建一个嵌套的FormGroup,当我在开发模式下使用该代码时,它没有显示任何问题并且编译完美。但是,当我尝试在生产模式下编译相同的代码时,它会使用"属性'控制'类型' AbstractControl'"。
上不存在component.ts:
import { Component, OnInit } from '@angular/core';
import { CustomerService } from '../../service/customer.service';
import { FormControl,FormGroup,FormBuilder,Validators,FormArray } from '@angular/forms';
enter code here
@Component({
selector: 'app-customer',
templateUrl: './customer.component.html',
styleUrls: ['./customer.component.css'],
providers: [CustomerService,GeolocationService]
})
export class CustomerComponent implements OnInit {
sheduleForm:FormGroup;
constructor(private service:CustomerService,private geoLocation:GeolocationService,private router:Router,private fb: FormBuilder) {
this.sheduleForm = fb.group({
user_schedule_details:fb.group({
mon:fb.group({
schedule_time:['00:00:00'],
status:[false]
}),
tue:fb.group({
schedule_time:['00:00:00'],
status:[false]
}),
wed:fb.group({
schedule_time:['00:00:00'],
status:[false]
}),
thu:fb.group({
schedule_time:['00:00:00'],
status:[false]
}),
fri:fb.group({
schedule_time:['00:00:00'],
status:[false]
}),
sat:fb.group({
schedule_time:['00:00:00'],
status:[false]
}),
sun:fb.group({
schedule_time:['00:00:00'],
status:[false]
})
}),
time_zone: [d.getTimezoneOffset()],
time_format : [false],
city:[null],
state:[null],
});
}
component.html:
<form [formGroup]="sheduleForm" (ngSubmit)="saveShedule(sheduleForm.value)" novalidate>
<div class="schedule_time">Schedule Time:
<span>
<md-input-container>
<input type="time" mdInput [formControl]="sheduleForm.controls['user_schedule_details'].controls['mon'].controls['schedule_time']">
</md-input-container>
</span>
</div>
</div>
...... so on.....
所以我在这个html中遇到了 [formControl] =&#34; sheduleForm.controls [&#39; user_schedule_details&#39;]。控件[&#39; mon&#39; ] .controls [&#39; schedule_time&#39;]&#34; 谁能帮帮我吗。我知道这个表单控件名称看起来很奇怪。但只有这样我才能访问表单值。如果这不是使用formControl的正确方法,请告诉我,我可以使用什么?
答案 0 :(得分:1)
尝试将HTML重构为:
<form [formGroup]="sheduleForm"
(ngSubmit)="saveShedule(sheduleForm.value)"
novalidate>
<div formGroupName="user_schedule_details">
<div formGroupName="mon">
<div class="schedule_time">Schedule Time:
<span>
<md-input-container>
<input type="time"
mdInput
formControlName="schedule_time"/>
</md-input-container>
</span>
</div>
</div>
...... so on.....
另外,如果您仍想使用[formControl]
,可以使用get()
函数执行此操作:
<md-input-container>
<input type="time"
mdInput
[formControl]="sheduleForm.get('user_schedule_details.mon.schedule_time)"/>
</md-input-container>
甚至
[formControl]="sheduleForm.get('user_schedule_details').get('mon').get('schedule_time')"
