在复选框更改时获取Angular2表单值

import { Component } from '@angular/core';
import { FormBuilder, FormGroup } from '@angular/forms';

@Component({
  selector: 'app-example',
  template: `
    <form [formGroup]="myForm">
      <label>
        <input type="checkbox" formControlName="myCheckbox"> Checkbox
      </label>
    </form>
  `
})
export class ExampleComponent {
  myForm: FormGroup;

  constructor(private formBuilder: FormBuilder) {
    this.myForm = this.formBuilder.group({
      myCheckbox: false
    });

    this.myForm.get('myCheckbox').valueChanges.subscribe(value => {
      console.log(value); // 在这里获取复选框的值
    });
  }
}
