JS验证日期及时间

验证日期+时间

 1 function checkDateTime(date){
 2     var reg = /^(\d{1,4})(-|\/)(\d{1,2})\2(\d{1,2}) (\d{1,2}):(\d{1,2}):(\d{1,2})$/;
 3     var r = date.match(reg);
 4     if(r == null){
 5         alert("输入格式不正确，请按yyyy-MM-dd HH:mm:ss的格式输入！");
 6         return false;
 7     }else{
 8     return true;
 9     }        
10 }

日期格式化

 1 Date.prototype.format = function(format) //author: meizz 
 2 { 
 3   var o = { 
 4     "M+" : this.getMonth()+1, //month 
 5     "d+" : this.getDate(),    //day 
 6     "h+" : this.getHours(),   //hour 
 7     "m+" : this.getMinutes(), //minute 
 8     "s+" : this.getSeconds(), //second 
 9     "q+" : Math.floor((this.getMonth()+3)/3),  //quarter 
10     "S" : this.getMilliseconds() //millisecond 
11   } 
12   if(/(y+)/.test(format)) format=format.replace(RegExp.$1, 
13     (this.getFullYear()+"").substr(4 - RegExp.$1.length)); 
14   for(var k in o)if(new RegExp("("+ k +")").test(format)) 
15     format = format.replace(RegExp.$1, 
16       RegExp.$1.length==1 ? o[k] : 
17         ("00"+ o[k]).substr((""+ o[k]).length)); 
18   return format; 
19 } 
20 alert(new Date().format("yyyy-MM-dd")); 
21 alert(new Date("january 12 2008 11:12:30").format("yyyy-MM-dd hh:mm:ss"));
