Question

我正面临着实现粒子JS的问题。我添加了两个JS文件但没有在浏览器中获得任何输出。这是我的代码。

<html lang="en">
<head>
  <meta charset="utf-8">
  <title>particles.js</title>
  <meta name="description" content="particles.js is a lightweight JavaScript library for creating particles.">
  <meta name="author" content="Vincent Garreau" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">
</head>
<body id="particles-js" bgcolor="#000000">
<!-- count particles -->
<!-- particles.js container -->
<!-- scripts -->
<script src="js/particles.min.js"></script>
<script src="js/app.js"></script>
</body>
</html>

Answer 1

您的身体标签存在问题。身体标签内部没有任何内容。也没有定义网页宽度和高度的CSS。你可以做的是在body中创建另一个分区并为该div添加ID。见下面的代码。

particlesJS("particles-js", {"particles":{"number":{"value":80,"density":{"enable":true,"value_area":800}},"color":{"value":"#ffffff"},"shape":{"type":"circle","stroke":{"width":0,"color":"#000000"},"polygon":{"nb_sides":5},"image":{"src":"img/github.svg","width":100,"height":100}},"opacity":{"value":0.5,"random":false,"anim":{"enable":false,"speed":1,"opacity_min":0.1,"sync":false}},"size":{"value":3,"random":true,"anim":{"enable":false,"speed":40,"size_min":0.1,"sync":false}},"line_linked":{"enable":true,"distance":150,"color":"#ffffff","opacity":0.4,"width":1},"move":{"enable":true,"speed":6,"direction":"none","random":false,"straight":false,"out_mode":"out","bounce":false,"attract":{"enable":false,"rotateX":600,"rotateY":1200}}},"interactivity":{"detect_on":"canvas","events":{"onhover":{"enable":true,"mode":"repulse"},"onclick":{"enable":true,"mode":"push"},"resize":true},"modes":{"grab":{"distance":400,"line_linked":{"opacity":1}},"bubble":{"distance":400,"size":40,"duration":2,"opacity":8,"speed":3},"repulse":{"distance":200,"duration":0.4},"push":{"particles_nb":4},"remove":{"particles_nb":2}}},"retina_detect":true});var count_particles, stats, update; stats = new Stats; stats.setMode(0); stats.domElement.style.position = 'absolute'; stats.domElement.style.left = '0px'; stats.domElement.style.top = '0px'; document.body.appendChild(stats.domElement); count_particles = document.querySelector('.js-count-particles'); update = function() { stats.begin(); stats.end(); if (window.pJSDom[0].pJS.particles && window.pJSDom[0].pJS.particles.array) { count_particles.innerText = window.pJSDom[0].pJS.particles.array.length; } requestAnimationFrame(update); }; requestAnimationFrame(update);;

/* ---- reset ---- */ body{ margin:0; font:normal 75% Arial, Helvetica, sans-serif; } canvas{ display: block; vertical-align: bottom; } /* ---- particles.js container ---- */ #particles-js{ position:absolute; width: 100%; height: 100%; background-color: #b61924; background-image: url(""); background-repeat: no-repeat; background-size: cover; background-position: 50% 50%; } /* ---- stats.js ---- */ .count-particles{ background: #000022; position: absolute; top: 48px; left: 0; width: 80px; color: #13E8E9; font-size: .8em; text-align: left; text-indent: 4px; line-height: 14px; padding-bottom: 2px; font-family: Helvetica, Arial, sans-serif; font-weight: bold; } .js-count-particles{ font-size: 1.1em; } #stats, .count-particles{ -webkit-user-select: none; margin-top: 5px; margin-left: 5px; } #stats{ border-radius: 3px 3px 0 0; overflow: hidden; } .count-particles{ border-radius: 0 0 3px 3px; }
