自移动且节点可切断的互动粒子背景特效

一款自移动且节点可切断的互动粒子背景特效，随便名字稍微有一点点的拗口，但时这样的带互动的粒子背景效果还时挺酷炫的，每个节点都能点击切断，挺不错的哦，喜欢的童鞋请收下吧。

页面的head部分，先引入一个关键的JS文件particles.min.js，然后设置好页面的样式，代码如下：

<script type="text/javascript" src="js/particles.min.js"></script>
<style type="text/css">
body,
html {
  background-color: #222;
  width: 100%;
  height: 100%;
  padding: 0;
  margin: 0;
  overflow: hidden;
}
</style>

页面的body部分，仅需要一个指定id的div容器即可，代码如下：

<div id="particles-js"></div>

页面的底部，主要是对particlesJS插件的参数设置，代码如下：

<script type="text/javascript">
/* --插件设置-- */
particlesJS("particles-js", {
  "particles": {

      "value": 300,
