Analyze and solve the problem that Vue screen cannot slide

When using Vue to develop mobile applications, sometimes you encounter the problem that the screen cannot slide, which brings great inconvenience to users. In this article, we analyze the causes of this problem and how to solve it.

Cause of the problem

The reasons why the screen cannot slide can be divided into two situations:

1. The height is not set

In Vue, if an element If the height is not set, the height of the element defaults to 0. If we want to make an element scrollable, we need to set the height of the element and put the content inside it in a container. The container needs to set the height and set the overflow-y attribute to scroll or auto. For example:

<style>
  .scrollable {
    height: 200px; /* 需要设置高度 */
    overflow-y: scroll; /* 或auto */
  }
</style>

<div class="scrollable">
  <!-- 内容放在一个容器中 -->
</div>

2. Sliding is prohibited

On the mobile side, the browser may disable page sliding in order to prevent misoperation. In the Vue application, if we turn on the rubber band effect (that is, a pulling effect will appear when sliding to the edge of the page), then the way to disable sliding is as follows:

// 禁止页面滑动
document.body.style.overflow = 'hidden';

This code will set the overflow attribute of the page It is hidden to achieve the effect of prohibiting page sliding. If we want to restore sliding, we can set the overflow attribute to auto:

// 恢复页面滑动
document.body.style.overflow = 'auto';

Solution

To solve the problem that the screen cannot slide, we can analyze and handle it according to the actual situation. If the problem is caused by not setting the height, we need to set the height on the relevant element, put the content in a container, and set the overflow-y attribute to scroll or auto. If it is because sliding is disabled, we can restore sliding by setting the overflow attribute of the page.

In addition, if we are using a third-party component library, we can consider checking the documentation of the component library to see if there are solutions to similar problems. During development, we also need to pay more attention. Some components that activate special operations (such as carousels) need special processing to avoid sliding problems.

Summary

The solution to the problem of the screen not sliding is not difficult. We need to determine the cause of the problem first, and then deal with it accordingly according to the situation. During the development process, we also need to pay attention to special processing of some special operation components to provide users with a better experience.
