不重复问题的说明

Explanation of not Duplicate question

请检查粗体字，我已经有一个正常工作的副菜单，但是问题是我想在单击ion-button而不是ion-item时关闭该副菜单.

Please check the Bold text, I already have a working sidemenu, but the problem is I want to close the sidemenu when I click on ion-button, not on ion-item.

推荐答案

只需将ion-button封装在ion-menu-toggle元素中，就像这样:

Simply encapsulate your ion-button within an ion-menu-toggle element, like so:

<ion-menu-toggle>
  <ion-button>Toggle Menu</ion-button>
</ion-menu-toggle>

如果您不想使用ion-menu-toggle，则可以执行以下操作:

If you don't want to use ion-menu-toggle, you can do this instead:

在您的app.component.ts中:

In your app.component.ts:

import { MenuController } from '@ionic/angular'; //import MenuController to access toggle() method.

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html'
})
export class AppComponent {
  constructor(
    public menuCtrl: MenuController
  ) {
    this.initializeApp();
  }

toggleMenu() {
    this.menuCtrl.toggle(); //Add this method to your button click function
  }

}

在您的app.component.html中:

And in your app.component.html:

<ion-button (click)="toggleMenu()">Toggle Menu</ion-button>
