核心封装代码如下：
//图片动画封装 function SearchAnim(opts) { for(var i in SearchAnim.DEFAULTS) { if (opts[i] === undefined) { opts[i] = SearchAnim.DEFAULTS[i]; } } this.opts = opts; this.timer = null; this.elem = document.getElementById(opts.elemId); this.startAnim(); } SearchAnim.prototype.startAnim = function () { this.stopAnim(); this.timer = setInterval(() => { var startIndex = this.opts.startIndex; if (startIndex == 360) { this.opts.startIndex = 0; } this.elem.style.transform = "rotate("+ (startIndex) +"deg)"; this.opts.startIndex += 5; }, this.opts.delay); setTimeout(() => { this.stopAnim(); }, this.opts.duration); } SearchAnim.prototype.stopAnim = function() { if (this.timer != null) { clearInterval(this.timer); } } SearchAnim.DEFAULTS = { duration : 60000, delay : 200, direction : true, startIndex : 0, endIndex : 360 }
使用方法：
随便创建一img标签
然后如下调用即可：
new SearchAnim({ elemId : "wait-icon", delay : 20, });
