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+)/i.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; }

//使用方法 

var now = new Date(); 

var nowStr = now.format("yyyy-MM-dd hh:mm:ss"); 

//使用方法2: 

var testDate = new Date(); 

var testStr = testDate.format("YYYY年MM月dd日hh小时mm分ss秒"); 

alert(testStr); 

//示例： 

alert(new Date().format("yyyy年MM月dd日")); 

alert(new Date().format("MM/dd/yyyy")); 

alert(new Date().format("yyyyMMdd")); 

alert(new Date().format("yyyy-MM-dd hh:mm:ss"));
