Simply prevent swiping to open the ion-menu in Ionic 2, but leave the option to swipe to close

After coming across the solution to this particular question, I found the accepted answer quite helpful. However, I noticed that it disabled the swipe to close gesture as well.

Is there a way to only disable the swipe gesture for opening the menu, while keeping it active for closing the menu? I feel that having both functionalities would make the user experience more seamless. Unfortunately, my search through the Ionic documentation has not yielded any results on this specific matter.

<ion-menu [content]="content" [swipeEnabled]="false">...</ion-menu>

Answer №1

Although there is no built-in method to achieve this in Ionic, you can utilize the ionOpen and ionClose callbacks to manage when the swipe feature should be active or inactive:

  1. Activate the swipe functionality after opening the menu, allowing it to close the menu
  2. Deactivate the swipe functionality after closing the menu, preventing it from opening the menu

See this working example on StackBlitz.

View

<ion-menu persistent="true" [content]="content" 
(ionOpen)="enableSwipe()"     <!-- Enable when opening  -->
(ionClose)="disableSwipe()">  <!-- Disable when closing -->
    <ion-header>
        <ion-toolbar color="primary">
            <ion-title>Side menu</ion-title>
        </ion-toolbar>
    </ion-header>    
    <ion-content>
    </ion-content>
</ion-menu>

<!-- Prevent swipe-to-go-back for better user experience with side menus -->
<ion-nav [root]="rootPage" #content swipeBackEnabled="false"></ion-nav>

Component

import { Component, ViewEncapsulation } from '@angular/core';
import { MenuController } from 'ionic-angular';
import { HomePage } from '../pages/home/home';

@Component({
    templateUrl: 'app.html'
})
export class MyApp {
    public rootPage: any = HomePage;

    constructor(private menuCtrl: MenuController) {}

    ngAfterViewInit() {
      this.disableSwipe();
    }

    public enableSwipe(): void {
      this.menuCtrl.swipeEnable(true);
    }

    public disableSwipe(): void {
      this.menuCtrl.swipeEnable(false);
    }

  }
