本文实例讲述了JS实现图片旋转动画效果封装与使用。分享给大家供大家参考，具体如下：
核心封装代码如下：
{
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：
完整示例代码：
//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;
},endIndex : 360
}
new SearchAnim({
elemId : "wait-icon",});
