为什么不显示？
window.onload = function(){
var timedate= new Date("2016,8,22"); //自定义结束时间
var now = new Date(); //获取当前时间
var date = timedate.getTime() - now.getTime(); //得出的为毫秒
var time = Math.ceil(data/(1000 * 60 * 60 * 24)); //1000 * 60 * 60 * 24一天的秒数
if(time > 0 ){
document.getElementById('timeShow').innerHTML = time;
}
}
</script>
</head>
<body>
<div class="content2">
<div class="txtshow">距离设置时间还有<span id="timeShow"></span>天</div>
</div>
</body>
哪里出问题了？求解答
