js处理日期时间格式

 var unit ={
     ovo_dateFormat : function(date01,format){
         var date = date01;
         var weekday = ["日","一","二","三","四","五","六",];
         var config = {
             YYYY: date.getFullYear(),
             MM:(date.getMonth() + 1) < 10 ? "0" + (date.getMonth() + 1) : date.getMonth() + 1,
             DD: date.getDate() < 10 ? "0" + date.getDate() : date.getDate(),
             hh: date.getHours() < 10 ? "0" + date.getHours() : date.getHours(),
             mm:date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes(),
             ss: date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds(),
             W:weekday[date.getDay()]
         };

         for(var key1 in config){
             format = format.replace(key1,config[key1]);
         }
         return format;
     }
 };
