[JavaScript知识库]vue particles.js 登录背景实现粒子动效

粒子动画效果像蜘蛛网一样，铺平伸缩，丝滑翻转，给页面增加诸多有趣之处，令人眼前一亮。

简单小结粒子动效在vue中的实践和使用。

一，npm下载

npm install particles.js

二，新建 particles.json

{
    "particles": {
        "number": {
            "value": 80,
            "density": {
                "enable": true,
                "value_area": 800
            }
        },
        "color": {
            "value": "#dedede"
        },
        "shape": {
            "type": "polygon",
            "stroke": {
                "width": 0,
                "color": "#000000"
            },
            "polygon": {
                "nb_sides": 5

            "width": 1.8
        },

            "enable": true,
            "speed": 4,
            "direction": "none",
            "random": false,
            "straight": false,
            "out_mode": "out",

        }
    },
    "interactivity": {
        "detect_on": "canvas",
        "events": {
            "onhover": {
                "enable": true,
                "mode": "repulse"
            },
            "onclick": {
                "enable": true,
                "mode": "push"
            },
            "resize": true
        },
        "modes": {

            }
        }
    },
    "retina_detect": false
}

三，页面中引入

import particles from 'particles.js'
import PcParticles from "./particles.json"

四，页面渲染

a，

 <div class="login" id="particlesId"></div>

b，

#particlesId{
      position: relative;
      width: 100%;
      height: 600px;
      background:linear-gradient(0deg,rgb(7, 33, 99),rgb(3, 17, 51));
      background-repeat: no-repeat;
      background-size: cover;
      background-position: 50% 50%;
}

c，

 mounted(){
    particlesJS("particlesId",PcParticles)
  }

五，效果图
