@angular/forms 0.3.0 中的 ngFormControl 有什么变化吗？

Question

我正在将我的 Angular 应用程序从 rc4 升级到 rc5，包括将 angular 表单从 0.2.0 更新到 0.3.0。从那以后我一直收到以下错误，这似乎与 0.3.0

中对 ngFormControl 的更改有关

zone.js:461 Unhandled Promise rejection: Template parse errors:
Can't bind to 'ngFormControl' since it isn't a known property of 'input'. ("nput type="text" class="form-control search-input" name="search" placeholder="Search..." [value]="" [ERROR ->][ngFormControl]="searchFormControl">

在我的组件模板之一中引用的行代码是一个搜索框：

<p [hidden]=hideSearch>
  <input type="text" class="form-control search-input" name="search" placeholder="Search..." [value]="" [ngFormControl]="searchFormControl">
</p>

我找不到有关此功能已更改的任何信息。那么现在 ngFormControl 的合适替代品是什么？

编辑：对于上下文，这是整个组件 header.component.ts（FormModule 和 ReactiveFormModule 在 app.module.ts 中加载）

import { Component, EventEmitter, Input, Output} from '@angular/core';
import { Control } from '@angular/common';
import { OrbitService } from './orbit.service';
import 'rxjs/add/operator/debounceTime';

@Component({
  selector: 'orbit-header',

  template: `
    <div class="top-nav row">
      <h3 class="pull-left">Northmark</h3>
      <div class="col-md-2 col-md-offset10 pull-right">
        <p [hidden]=hideSearch>
        <!-- ng-model = [ngFormController] -->
          <input type="search" class="form-control search-input" name="search" placeholder="Search..." [value]="" [NgFormControl]="searchFormControl">
        </p>
        <p>
          <a class="log-out" (click)="orbitService.deleteCookie('ORBIT_COOKIE')">Log Out</a>
        </p>
      </div>
      <div class="clearfix"></div>
    </div>
  `
})

export class HeaderComponent implements OnInit {

  @Input() private hideSearch: boolean;

  constructor(
    private orbitService: OrbitService) {
    this.searchFormControl = new Control();
  }

  @Output() onSubmit = new EventEmitter<string>();

  ngOnInit() {
    this.searchFormControl.valueChanges
      .debounceTime(500)
      .subscribe(query => this.submit(query));
  }

  submit(query: string) {
    this.onSubmit.emit(query);
  }
}

Answer 1

[ngFormControl]="searchFormControl"

应该是

[formControl]="searchFormControl"

而且我认为您需要导入 ReactiveFormsModule

Did anything change to ngFormControl in @angular/forms 0.3.0?
