([ngmodel])对象在方法中发生更改时不刷新数据

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

@Component({
  selector: 'app-example',
  template: `
    <input [(ngModel)]="data">
    <button (click)="updateData()">Update Data</button>
  `
})
export class ExampleComponent {
  data: string;

  constructor(private cdr: ChangeDetectorRef) {}

  updateData() {
    // 修改[ngmodel]绑定的对象
    this.data = 'New Value';

    // 手动触发变更检测
    this.cdr.detectChanges();
  }
}

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

@Component({
  selector: 'app-example',
  template: `
    <input [(ngModel)]="data">
    <button (click)="updateData()">Update Data</button>
  `
})
export class ExampleComponent {
  data: string;

  updateData() {
    // 修改[ngmodel]绑定的对象
    this.data = 'New Value';

    // 使用setTimeout延迟执行异步操作
    setTimeout(() => {
      // 异步操作完成后，变更检测会自动触发
    }, 0);
  }
