How to solve the problem of right sliding back on mobile terminal in Vue development

With the popularity of mobile terminals, more and more websites and applications are beginning to use Vue as the front-end development framework. Vue is simple, easy to use and has excellent performance, allowing developers to build mobile applications more efficiently. However, when using Vue to develop mobile applications, we often encounter a problem: sliding right to return causes the page to jump.

On the mobile side, many applications hope that users can return to the previous page through a right swipe gesture, which can improve the user's operating experience. However, due to Vue's single page application (SPA) mode, the right swipe gesture is often intercepted by the browser's default return to the page operation, resulting in an incorrect page jump. So, how should we solve this problem?

First of all, we can solve the right slide return problem through Vue's navigation guard. Navigation guard is a routing hook function provided by Vue. It can perform some operations before, after routing switching or when the jump is cancelled. We can determine in the navigation guard whether the current page is returned through a right swipe gesture, and if so, cancel the page jump operation.

The specific operations are as follows:

1. In Vue’s routing configuration, add a meta value for the page that needs to be intercepted:

const routes = [
  {
    path: '/home',
    component: Home,
    meta: {
      allowBack: false
    }
  },
  // ...
];

2. In Add judgment logic to Vue's navigation guard:

const router = new VueRouter({
  routes
});

router.beforeEach((to, from, next) => {
  // 判断当前页面是否通过右滑手势返回
  const allowBack = from.meta.allowBack !== undefined ? from.meta.allowBack : true;

  // 如果是通过右滑手势返回，则取消页面跳转操作
  if (!allowBack) {
    next(false);
  } else {
    next();
  }
});

Through the above operations, we can solve the problem of page jump caused by right swiping back in mobile applications. When the user returns to the page through the right swipe gesture, the page will not jump to the previous page, but will stay on the current page.

In addition to using navigation guards, we can also solve the problem of sliding right to return in other ways. For example, you can use a third-party library to monitor and intercept the right swipe gesture, and then prevent the browser's default return operation in the listening event. This method can more precisely control the behavior of right-swipe back, but it requires the introduction of additional third-party libraries, which increases the complexity of the project.

In summary, solving the problem of right-sliding back on the mobile terminal is a common need in Vue development. By using Vue's navigation guard mechanism, we can simply implement page jump interception, thereby solving the problem of page jumps caused by right swiping back. Of course, we can also achieve similar effects in other ways, and the specific method can be selected based on actual needs and project conditions.
