vue中使用particles.js实现登录页炫酷动效

1、安装依赖

yarn add particles.js 或 npm install particles.js

2、src/components下新建particles文件夹，文件夹下新建index.vue和particles.json，代码如下

index.vue

<template>
    <div class="particles-js-box">
        <div id="particles-js"></div>
    </div>
</template>

<script>
    /* eslint-disable */
    import particlesJs from "particles.js";
    import particlesConfig from "./particles.json";
    export default {
        data() {
            return {};
        },
        mounted() {
            this.init();
        },
        methods: {
            init() {
                particlesJS("particles-js", particlesConfig);
                document.body.style.overflow = "hidden";
            }
        }
  } ;
</script>

<style scoped>
    .particles-js-box{
        position:fixed;
        width: 100%;
        height: 100%;
        top:0;
        left:0;
        z-index:1;  //这里建议层级设为-1，但-1可能会导致被其他元素遮挡
    }
    #particles-js{
        background-color:#2d3a4b;
        width: 100%;
        height: 100%;
    }
</style>

particles.json，动态样式配置参考官网： https://github.com/VincentGarreau/particles.js

            }
        }
    },
    "retina_detect": true
}

3、在login.vue页引入组件使用

<particles></particles>


import Particles from '@/components/particles/index'

components: {Particles},

可能需要重启项目才会生效

其实图里面的线条是动态的
