这个函数经常用到,分享给大家。

函数代码:

Date.prototype.format = function(format){
	var o = {
	"M+" : this.getMonth()+1, //month
	"d+" : this.getDate(),    //day
	"h+" : this.getHours(),   //hour
	"m+" : this.getMinutes(), //minute
	"s+" : this.getSeconds(), //second
	"q+" : Math.floor((this.getMonth()+3)/3),  //quarter
	"S" : this.getMilliseconds() //millisecond
	}
	if(/(y+)/.test(format)) format=format.replace(RegExp.$1,
	(this.getFullYear()+"").substr(4 - RegExp.$1.length));
	for(var k in o)if(new RegExp("("+ k +")").test(format))
	format = format.replace(RegExp.$1,
	RegExp.$1.length==1 ? o[k] :
	("00"+ o[k]).substr((""+ o[k]).length));
	return format;
}

调用示例:

<script type="text/javascript">
setInterval(function(){
	var time = new Date().format("hh:mm:ss");
	var date = new Date().format("yyyy-MM-dd");
	document.getElementById("Time").innerHTML=time;
	document.getElementById("Date").innerHTML=date;
},1000);

</script>
