var date = new Date(); //日期对象 
var now = ""; 
now = date.getFullYear()+"年"; //读英文即可了 
now = now + (date.getMonth()+1)+"月"; //取月的时候取的是当前月-1假设想取当前月+1就能够了 
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
