Javascript 如何在angular 4中使用ngModel从表单中获取值

我在输入框中使用ngModel时出现此错误。

在.html页面中

    <form>
    <div *ngIf="editTitle" class="form-group">
        <input type="input" class="form-control" name="title" required 
        placeholder="title" [(ngModel)]="video.title">
    </div>
        <h3 *ngIf="!editTitle" (click)="onTitleClick()">{{video.title}}</h3>
    </form>

import { Component, OnInit } from '@angular/core';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';

@Component({
selector: 'video-detail',
templateUrl: './video-detail.component.html',
styleUrls: ['./video-detail.component.css'],
inputs: ['video']
})
export class VideoDetailComponent implements OnInit {

private editTitle: boolean = false;
constructor() { }
ngOnInit() {
}

ngOnChanges(){
this.editTitle = false;
}

onTitleClick(){
this.editTitle = true;
}
}

似乎您以错误的方式获取输入。请尝试以下方式获取输入：

export class VideoDetailComponent implements OnInit {
  @Input() video:object;

  constructor() {
  }

  ngOnInit() {
  }
}

您还必须从“@angular/core”导入“Input”模块，如下所示：

import { Component, OnInit,Input } from '@angular/core';

app.component.html

<form><div *ngIf="editTitle" class="form-group">
  <input type="input" class="form-control" name="title" required 
  placeholder="title" [(ngModel)]="video.title"></div>
  <h3 *ngIf="!editTitle" (click)="onTitleClick()">{{video.title}}</h3>
  </form>

app.component.ts

import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
video: any = {};
private editTitle: boolean = false;
constructor() { }
ngOnInit() { }
ngOnChanges(){
this.editTitle = false;
}
onTitleClick(){
this.editTitle = true;
}
}

实际上你想要什么，伙计？你能不能也给出错误的详细信息？错误：不，这不会很好地工作，我对angular 4没有太多的知识，这是错误图像：编辑我的答案：尝试从angular导入输入模块，如下所示：

import{Component，OnInit，Input}来自“@angular/core”谢谢Ravi Teja。它工作：）这是我的荣幸抱歉，我不能，因为它显示了此错误消息
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
video: any = {};
private editTitle: boolean = false;
constructor() { }
ngOnInit() { }
ngOnChanges(){
this.editTitle = false;
}
onTitleClick(){
this.editTitle = true;
}
}
