我正在使用ReactiveFormsModuleAngular2来创建包含表单的组件.这是我的代码:

foo.component.ts:

constructor(fb: FormBuilder) {
    this.myForm = fb.group({
        'fullname': ['', Validators.required],
        'gender': []
    });
}

foo.component.html(with [formControl]):

<div class="fields">
    <div class="field">
        <label>Fullname*</label>
        <input type="text" [formControl]="myForm.controls.fullname"/>
    </div>
</div>

<div class="inline fields">
    <label for="gender">Gender</label>
    <div class="field">
        <div class="ui radio checkbox">
            <input type="radio" name="gender" checked="" tabindex="0" class="hidden" [formControl]="myForm.controls.gender">
            <label>Male</label>
        </div>
    </div>
    <div class="field">
        <div class="ui radio checkbox">
            <input type="radio" name="gender" tabindex="0" class="hidden" [formControl]="myForm.controls.gender">
            <label>Female</label>
        </div>
    </div>
</div>

foo.component.html(with formControlName):

<div class="fields">
    <div class="field">
        <label>Fullname*</label>
        <input type="text" …

我在stackoverflow中的许多问题中发现了这个问题,但没有运气.请帮我弄清楚我做错了什么.

在组件中:

ngOnInit() {
    this.companyCreatForm = this._formBuilder.group({
      name: [null, [Validators.required, Validators.minLength(5)]],
      about: [null, [Validators.required]],
      businessType: [null, [Validators.required]],
      address: this._formBuilder.group({
        street: [],
        website: [null, [Validators.required]],
        mobile: [null, [Validators.required]],
        email: [null, [Validators.required]],
        pageId: [null, [Validators.required]],
      }),
    });

表格:

<form [formGroup]="companyCreatForm" (ngSubmit)="creat_company()" novalidate class="form-horizontal">
    <div class="panel panel-default" *ngIf="generalPanel">
        <div class="panel-heading">General Info</div>
        <div class="panel-body">
            <div class="form-group">
                <label for="comapny name" class="col-sm-3 control-label">Company's Name</label>
                <div class="col-sm-8">
                    <input type="text" class="form-control" placeholder="Company's Name" formControlName="name" #refName>
                    <div *ngIf="companyCreatForm.controls['name'].hasError('required') && refName.touched" class="alert alert-danger">
                        please enter name
                    </div>
                    <div *ngIf="companyCreatForm.controls['name'].hasError('minlength')" class="alert …
