雙向繫結 (Two Way Binding)

Template語法：

<element [(ngModel)]="變數名稱"></element>

程式碼範例：

1.在Component.ts中加入變數myModel

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

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

  myModel = "";

  constructor() { }

  ngOnInit() {
  }

}

2.在Template中使用雙向繫結該變數

<input type="text" [(ngModel)]="變數名稱"> <button>確定</button>
