How to solve the sliding loading problem on mobile terminal?

With the popularity of mobile devices and the increasing user demand for mobile applications, developing mobile applications has become an important task for developers. In mobile applications, sliding loading is more of a common interaction method, which can improve user experience and increase the usability of the page. This article will introduce how to solve the problem of more sliding loading on the mobile terminal in Vue development.

1. Understand the implementation principles of sliding loading on the mobile terminal
Before introducing the solution, we first need to understand the implementation principles of sliding loading on the mobile terminal. On mobile devices, users perform sliding operations by touching the screen, and the sliding effect is achieved by monitoring touch events. When the user scrolls to the bottom of the page, we need to trigger an action that loads more. In order to achieve this function, we can listen to the scroll event of the page and calculate the scroll position of the page to determine whether to trigger the loading of more operations.

2. Solution

1. Use BetterScroll plug-in
   BetterScroll is a powerful mobile scrolling component that can achieve smooth scrolling effects and sliding loading of more functions. We can integrate BetterScroll with Vue to achieve more sliding loading functions on the mobile terminal.

First, we need to introduce the BetterScroll plug-in into the project. It can be installed through the npm package management tool:

npm install better-scroll --save

Then, in the Vue component that needs to use sliding loading to load more functions, introduce BetterScroll:

import BScroll from 'better-scroll'

Next, we need to initialize the BetterScroll instance and listen for scroll events in the instance:

mounted() {
this.scroll = new BScroll(this.$refs.wrapper, {

probeType: 3 //监听滚动事件

})

this.scroll.on('scroll', (pos) => {

//判断是否触发加载更多的条件
if (pos.y <= (this.scroll.maxScrollY + 50)) {
  this.loadMore()
}

})
}

In the above code, we use the mounted hook function to create a BetterScroll instance, and listen to the scroll event to determine whether to trigger loading of more conditions. The loadMore function is our custom load more function, where we can perform the operation of loading data.

2. Use Vue's transition component to achieve more sliding loading animation effects
   In addition to realizing the sliding loading more function, we can also use Vue's transition component to add animation for loading more effect and enhance user experience.

In the Vue component, we can use Vue's transition component to wrap more content and customize animation effects, such as gradient effects, fade-in and fade-out, etc.

In the above code, we use Vue's transition component to wrap and load more content, and define an animation effect named "fade" for it. Use the v-if instruction to control the loading of more displays, and set the value of the showLoadMore variable to control the loading of more displays and hides.

3. Summary
Sliding loading is more of a common mobile application interaction method, which can improve user experience and page usability. In Vue development, we can achieve more sliding loading functions and animation effects by using the BetterScroll plug-in and Vue's transition component. Through the above solutions, we can provide better user experience for mobile applications and improve the use value of the application.
