在html部分引入的animate.js文件部分代码

/**

function animate(obj,json,fn) {
 clearInterval(obj.timer);
 obj.timer = setInterval(function () {
 var flag = true;
 for(var k in json){
 if( k == "opacity"){
 var leader = getStyle(obj,k) * 100;
 var target = json[k] * 100;
 var step = (target - leader) /10;
 step = step > 0 ? Math.ceil(step) : Math.floor(step);
 leader = leader + step;
 obj.style[k] = leader /100;
 } else if ( k == "zIndex"){
 obj.style[k] = json[k];
 }else{
 var leader = parseInt(getStyle(obj,k)) || 0;
 var target = json[k];
 var step = (target - leader) /10;
 step = step >0 ? Math.ceil(step) : Math.floor(step);
 leader = leader + step;
 obj.style[k] = leader + "px";
 }
 
 console.log("target:" + target + "leader:" + leader + "step:" + step);
 if (leader != target){
 flag = false;
 }
 }
 
 if (flag){
 clearInterval(obj.timer);
 if(fn){
 fn();
 }
 }
 },15)
}
 
function getStyle(obj,attr){
 if (obj.currentStyle){
 return obj.currentStyle[attr];
 }else{
 return window.getComputedStyle(obj,null)[attr];
 }
}

在html部分引入的my.js文件部分代码

/**

window.onload = function () {
 var wrap = document.getElementById("wrap");
 var slide = document.getElementById("slide");
 var ul = slide.children[0];
 var lis = ul.children;
 var arrow = document.getElementById("arrow");
 var arrRight = document.getElementById("arrRight");
 var arrLeft = document.getElementById("arrLeft");
 
 var config = [
 {
 width:400,
 top:20,

 wrap.onmouseover = function () {

 }
 wrap.onmouseout = function () {
 animate(arrow,{"opacity":0});
 }
 function assign() {
 for(var i = 0;i < lis.length;i++){
 animate(lis[i],config[i],function(){
 flag = true;
 })
 }
 }
 
 var flag = true;
 assign();
 arrRight.onclick = function () {
 flag = false;
 config.push(config.shift());
 assign();
 };
 arrLeft.onclick = function () {
 flag = false;
 config.unshift(config.pop());
 assign();
 }
