HTML5贪吃蛇源码-白红宇

显示效果如下：代码下载：

function show(){

var date = new Date(); //日期对象

var now = "";

now = date.getFullYear()+"年"; //读英文就行了

now = now + (date.getMonth()+1)+"月"; //取月的时候取的是当前月-1如果想取当前月+1就可以了

now = now + date.getDate()+"日";

now = now + date.getHours()+"时";

now = now + date.getMinutes()+"分";

now = now + date.getSeconds()+"秒";

document.getElementById("nowDiv").innerHTML = now; //div的html是now这个字符串

setTimeout("show()",1000); //设置过1000毫秒就是1秒，调用show方法

}
