参数：

 target ： 目标元素的id
 startVal ： 你想要开始的值
 endVal ： 你想要到达的值
 decimals ： 小数位数，默认值为0
 duration ： 动画持续时间为秒，默认值为2
 options ：选项的可选对象

//options对象参数

options = {
useEasing: true, // toggle easing
useGrouping: true, // 1,000,000 vs 1000000
separator: ',', // character to use as a separator
decimal: '.', // character to use as a decimal
easingFn: easeOutExpo, // optional custom easing function, default is Robert Penner's easeOutExpo
formattingFn: formatNumber, // optional custom formatting function, default is formatNumber above
prefix: '', // optional text before the result
suffix: '', // optional text after the result
numerals: [] // optionally pass an array of custom numerals for 0-9
};

还有几个方法：

//暂停/恢复

money1.pauseResume();

//重置动画

money1.reset();

//更新值

var someValue = 6666;

money1.update(someValue);

附上countUp.js压缩后的源码，就不用去下载啦 ctrl+c ctrl+v 哈哈哈、

var CountUp=function(target,startVal,endVal,decimals,duration,options){var self=this;self.version=function(){return"1.9.2"};self.options={useEasing:true,useGrouping:true,separator:",",decimal:".",easingFn:easeOutExpo,formattingFn:formatNumber,prefix:"",suffix:"",numerals:[]};if(options&&typeof options==="object"){for(var key in self.options){if(options.hasOwnProperty(key)&&options[key]!==null){self.options[key]=options[key]}}}if(self.options.separator===""){self.options.useGrouping=false}else{self.options.separator=""+self.options.separator}var lastTime=0;var vendors=["webkit","moz","ms","o"];for(var x=0;x1?self.options.decimal+x[1]:"";if(self.options.useGrouping){x3="";for(i=0,l=x1.length;iself.endVal);self.frameVal=self.startVal;self.initialized=true;return true}else{self.error="[CountUp] startVal ("+startVal+") or endVal ("+endVal+") is not a number";return false}};self.printValue=function(value){var result=self.options.formattingFn(value);if(self.d.tagName==="INPUT"){this.d.value=result}else{if(self.d.tagName==="text"||self.d.tagName==="tspan"){this.d.textContent=result}else{this.d.innerHTML=result}}};self.count=function(timestamp){if(!self.startTime){self.startTime=timestamp}self.timestamp=timestamp;var progress=timestamp-self.startTime;self.remaining=self.duration-progress;if(self.options.useEasing){if(self.countDown){self.frameVal=self.startVal-self.options.easingFn(progress,0,self.startVal-self.endVal,self.duration)}else{self.frameVal=self.options.easingFn(progress,self.startVal,self.endVal-self.startVal,self.duration)}}else{if(self.countDown){self.frameVal=self.startVal-((self.startVal-self.endVal)*(progress/self.duration))}else{self.frameVal=self.startVal+(self.endVal-self.startVal)*(progress/self.duration)}}if(self.countDown){self.frameVal=(self.frameValself.endVal)?self.endVal:self.frameVal}self.frameVal=Math.round(self.frameVal*self.dec)/self.dec;self.printValue(self.frameVal);if(progressself.endVal);self.rAF=requestAnimationFrame(self.count)};if(self.initialize()){self.printValue(self.startVal)}};
