Anime.js是一个js动画库插件，我们的动画以它为基础绘制的。
我们先去官方下载anime.mini.js或anime.js
我用的next主题，添加到themes/next/source/js下，然后在此文件夹再自己创建特效文件click.js，代码如下：
function updateCoords(e) { pointerX = (e.clientX || e.touches[0].clientX) - canvasEl.getBoundingClientRect().left, pointerY = e.clientY || e.touches[0].clientY - canvasEl.getBoundingClientRect().top } function setParticuleDirection(e) { var t = anime.random(0, 360) * Math.PI / 180 , a = anime.random(50, 180) , n = [-1, 1][anime.random(0, 1)] * a; return { x: e.x + n * Math.cos(t), y: e.y + n * Math.sin(t) } } function createParticule(e, t) { var a = {}; return a.x = e, a.y = t, a.color = colors[anime.random(0, colors.length - 1)], a.radius = anime.random(16, 32), a.endPos = setParticuleDirection(a), a.draw = function() { ctx.beginPath(), ctx.arc(a.x, a.y, a.radius, 0, 2 * Math.PI, !0), ctx.fillStyle = a.color, ctx.fill() } , a } function createCircle(e, t) { var a = {}; return a.x = e, a.y = t, a.color = "#F00", a.radius = .1, a.alpha = .5, a.lineWidth = 6, a.draw = function() { ctx.globalAlpha = a.alpha, ctx.beginPath(), ctx.arc(a.x, a.y, a.radius, 0, 2 * Math.PI, !0), ctx.lineWidth = a.lineWidth, ctx.strokeStyle = a.color, ctx.stroke(), ctx.globalAlpha = 1 } , a } function renderParticule(e) { for (var t = 0; t < e.animatables.length; t++) e.animatables[t].target.draw() } function animateParticules(e, t) { for (var a = createCircle(e, t), n = [], i = 0; i < numberOfParticules; i++) n.push(createParticule(e, t)); anime.timeline().add({ targets: n, x: function(e) { return e.endPos.x }, y: function(e) { return e.endPos.y }, radius: .1, duration: anime.random(1200, 1800), easing: "easeOutExpo", update: renderParticule }).add({ targets: a, radius: anime.random(80, 160), lineWidth: 0, alpha: { value: 0, easing: "linear", duration: anime.random(600, 800) }, duration: anime.random(1200, 1800), easing: "easeOutExpo", update: renderParticule, offset: 0 }) } function debounce(fn, delay) { var timer return function () { var context = this var args = arguments clearTimeout(timer) timer = setTimeout(function () { fn.apply(context, args) }, delay) } } var canvasEl = document.querySelector(".fireworks"); if (canvasEl) { var ctx = canvasEl.getContext("2d") , numberOfParticules = 30 , pointerX = 0 , pointerY = 0 , tap = "mousedown" , colors = ["#FF1461", "#18FF92", "#5A87FF", "#FBF38C"] , setCanvasSize = debounce(function() { canvasEl.width = 2 * window.innerWidth, canvasEl.height = 2 * window.innerHeight, canvasEl.style.width = window.innerWidth + "px", canvasEl.style.height = window.innerHeight + "px", canvasEl.getContext("2d").scale(2, 2) },500) , render = anime({ duration: 1 / 0, update: function() { ctx.clearRect(0, 0, canvasEl.width, canvasEl.height) } }); document.addEventListener(tap, function(e) { "sidebar" !== e.target.id && "toggle-sidebar" !== e.target.id && "A" !== e.target.nodeName && "IMG" !== e.target.nodeName && (render.play(), updateCoords(e), animateParticules(pointerX, pointerY)) }, !1), setCanvasSize(), window.addEventListener("resize", setCanvasSize, !1) }
我们打开themes/next/layout/_layout.swig，在<body>中添加：
{% if theme.click %} <canvas class="click" style="position: fixed;left: 0;top: 0;z-index: 1; pointer-events: none;" ></canvas> <script type="text/javascript" src="/js/click.js"></script> <script type="text/javascript" src="/js/anime.min.js"></script> {% endif %}
保存，并在主题配置文件下新增click=true，即可开启特效。
