Vue3實(shí)現(xiàn)粒子動態(tài)背景的示例詳解

更新時間：2023年11月22日 14:46:01 作者：會說法語的豬

這篇文章主要為大家詳細(xì)介紹了如何利用Vue3實(shí)現(xiàn)粒子動態(tài)背景,文中的示例代碼講解詳細(xì),具有一定的學(xué)習(xí)價值,感興趣的小伙伴可以跟隨小編一起了解一下

安裝

pnpm add particles.vue3
pnpm add tsparticles-slim

注冊

main.js

import { createApp } from 'vue'
import type { App } from 'vue'
import globleApp from './App.vue'
import router from './router'
import Particles from "particles.vue3"
 
const app: App = createApp(globleApp)
 
app.use(router)
   .use(Particles)
   .mount('#app')

引入使用

完整代碼

<template>
  <div class="wft-particles-container" :style="particlesContainerStyle">
    <vue-particles 
      id="wft-tsparticles"
      :particlesInit="particlesInit"
      :options="particlesOpt"
    />
  </div>
</template>
<script setup lang="ts">
import particlesOpt from './config/particles1'
import { loadSlim } from "tsparticles-slim"
import { computed } from 'vue'
 
const props = withDefaults(defineProps<{
  width?: string | number,
  height?: string | number,
  backgroundColor?: string,
  backgroundImage?: string
}>(), {
  width: '100%',
  height: '100%',
  backgroundColor: '#002a3a',
  backgroundImage: ''
})
 
const particlesContainerStyle = computed(() => {
  return {
    width: typeof props.width === 'string' ? props.width : props.width + 'px',
    height: typeof props.height === 'string' ? props.height : props.height + 'px',
    backgroundColor: props.backgroundColor,
    backgroundImage: `url(${props.backgroundImage})`
  }
})
 
const particlesInit = async (engine: any) => {
  await loadSlim(engine);
}
</script>
<style scoped>
.wft-particles-container {
  display: flex;
  justify-content: center;
  align-items: center;
  position: relative;
  background-size: 100% 100%;
  background-repeat: no-repeat;
}
 
#wft-tsparticles {
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  height: 100%;
  z-index: 0;
}
</style>

其中的options配置：

可以在同級新建config文件夾，新建particles1.ts, particles2.ts,里面定義配置項(xiàng)數(shù)據(jù)并向外導(dǎo)出
