 详细说明: HTML5圆形波浪加载动画特效是一款原生html5 css3 canvas波浪滚动上升加载动画,圆形加载容器效果。 var wave = (function () { var ctx; var waveImage; var canvasWidth; var canvasHeight; var needAnimate = false; function init (callback) { var wave = document.getElementById(wave); var canvas = document.createElement(canvas); if (!canv as.getContext) return; ctx = canvas.getContext(2d); canvasWidth = wave.offsetWidth; canvasHeight = wave.offsetHeight; canvas.setAttribute(width, canvasWidth); canvas.setAttribute(height, canvasHeight); wave.appendChild(canvas); waveImage = new Image(); waveImage.onload = function () { waveImage.onload = null; callback(); } waveImage.src = images/wave.png; } function animate () { var waveX = 0; var waveY = 0; var waveX_min = -203; var waveY_max = canvasHeight * 0.7; var requestAnimationFrame =  window.requestAnimationFrame ||  window.mozRequestAnimationFrame ||  window.webkitRequestAnimationFrame ||  window.msRequestAnimationFrame || function (callback) { window.setTimeout(callback, 1000 / 60); }; function loop () { ctx.clearRect(0, 0, canvasWidth, canvasHeight); if (!needAnimate) return; if (waveY < waveY_max) waveY = 1.5; if (waveX < waveX_min) waveX = 0; else waveX -= 3; ctx.globalCompositeOperation = source-over; ctx.beginPath(); ctx.arc(canvasWidth/2, canvasHeight/2, canvasHeight/2, 0, Math.PI*2, true); ctx.closePath(); ctx.fill(); ctx.globalCompositeOperation = source-in; ctx.drawImage(waveImage, waveX, canvasHeight - waveY); requestAnimationFrame(loop); } loop(); } function start () { if (!ctx) return init(start); needAnimate = true; setTimeout(function () { if (needAnimate) animate(); }, 500); } function stop () { needAnimate = false; } return {start: start, stop: stop}; }()); wave.start();
