How to solve the mobile gesture sliding problem in Vue development

In Vue development, mobile gesture sliding is a common requirement and problem. With the popularity of mobile devices and changes in user needs, we increasingly need to implement gesture sliding functions in mobile applications. This article will introduce some common solutions to help developers easily implement mobile gesture sliding in Vue development.

1. Use a third-party library

A simple and effective solution is to use a third-party library, such as Hammer.js. Hammer.js is a powerful JavaScript library for gestural swiping, zooming, and rotating operations on mobile devices. It supports a variety of gesture events, including swipe, pinch, rotate, etc.

Using Hammer.js in Vue development is also very simple. First, introduce Hammer.js into the project through npm or directly introduce CDN. Then, in the component that needs to use gesture sliding, create an instance, initialize Hammer.js in the mounted life cycle hook function, and bind the corresponding gesture event:

import Hammer from 'hammerjs'

export default {
  mounted() {
    const element = document.getElementById('your-element-id')
    const hammer = new Hammer(element)

    hammer.on('swipe', (event) => {
      // 处理滑动事件
    })
  }
}

2. Use Vue plug-in

If you don’t want to introduce an additional library, you can also consider using the existing Vue plug-in to solve the mobile gesture sliding problem. There are many open source gesture sliding plug-ins to choose from in the Vue community. For example, v-touch can help us easily implement gesture sliding functions in Vue.

Using v-touch is very simple. Introduce the v-touch plug-in into the project, then add the v-touch instruction in the component that needs to use gesture sliding, and bind the corresponding event handling function:

<template>
  <div v-touch:swipe="handleSwipe"></div>
</template>

<script>
export default {
  methods: {
    handleSwipe(event) {
      // 处理滑动事件
    }
  }
}
</script>

3. Use native events

If you don’t want to use a third-party library or Vue plug-in, you can also implement the gesture sliding function through native events. In Vue, we can directly use events such as @touchstart, @touchmove and @touchend to handle gesture sliding.

First, add touch event monitoring in the component that requires gesture sliding:

<template>
  <div @touchstart="handleTouchStart" @touchmove="handleTouchMove" @touchend="handleTouchEnd"></div>
</template>

<script>
export default {
  methods: {
    handleTouchStart(event) {
      // 记录滑动起点的坐标
    },
    handleTouchMove(event) {
      // 计算滑动距离，并触发相应的动作
    },
    handleTouchEnd(event) {
      // 清除滑动相关的数据
    }
  }
}
</script>

By listening to touch events, we can implement the logic of gesture sliding in the component ourselves, such as recording the starting point coordinates , calculate sliding distance, etc.

Summary

In Vue development, it is not difficult to solve the mobile gesture sliding problem. We can use third-party libraries, Vue plug-ins or native events to implement gesture sliding functions. Choosing the right solution can greatly improve development efficiency and bring a better user experience.
