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;

console.log("target:" + target + "leader:" + leader + "step:" + step);

flag = false;

}

}

if (flag){

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

/**

var config = [
