angular – 最简洁的方式来重置表单

在Angular 2最新版本中重置表单的最简洁方法是什么？我想在添加帖子后重置输入文本框.

@Component({
  selector: 'post-div',template: `
            <h2>Posts</h2>
            <form (submit)="addPost()">
                <label>Title: </label><input type="text" name="title" [(ngModel)]="title"><br/>
                <label>Body: </label><input type="text" name="body" [(ngModel)]="body"><br/>
                <input type="submit" value="Add Post">
            </form>
            <ul>
                <li *ngFor="let post of posts">
                    <strong>{{post.title}}</strong>
                    <p>{{post.body}}</p>
                </li>
            </ul>
          `,providers: [PostService]
});

addPost(){
    this.newPost = {
        title: this.title,body: this.body
    }
    this._postService.addPost(this.newPost);
}

<form #myForm="ngForm" (submit)="addPost(); myForm.reset()"> ... </form>

要么：

<form #myForm="ngForm" (submit)="addPost(myForm)"> ... </form>

addPost(form: NgForm){
    this.newPost = {
        title: this.title,body: this.body
    }
    this._postService.addPost(this.newPost);
    form.resetForm(); // or form.reset();
}

为无法完成上述工作的人添加另一个示例.

按下按钮：

<form #heroForm="ngForm">
    ...
    <button type="button" class="btn btn-default" (click)="newHero(); heroForm.reset()">New Hero</button>
</form>

同样适用于上述内容,您也可以选择将表单传递给newHero函数.
