Angular中的复选框在提交时不接受最新值

<form #myForm="ngForm" (ngSubmit)="onSubmit(myForm)">
  <input type="checkbox" name="agree" [(ngModel)]="user.agree" (change)="onCheckboxChange()"> I agree to the terms
  <button type="submit">Submit</button>
</form>

export class MyComponent {
  user = { agree: false };

  onCheckboxChange() {
    // 手动触发脏状态
    this.myForm.controls['agree'].markAsDirty();
  }

  onSubmit(form: NgForm) {
    if (form.valid) {
      console.log('Form submitted with:', form.value);
    } else {
      console.log('Form is invalid');
    }
  }
}

<form [formGroup]="myForm" (ngSubmit)="onSubmit()">
  <input type="checkbox" formControlName="agree"> I agree to the terms
  <button type="submit">Submit</button>
</form>

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