JS以指定格式获取当前日期

 //获取当前时间，格式YYYY-MM-DD
     function getNowFormatDate() {
         var date = new Date();
         var seperator1 = "-";
         var year = date.getFullYear();
         var month = date.getMonth() + 1;
         var strDate = date.getDate();
         if (month >= 1 && month <= 9) {
             month = "0" + month;
         }
         if (strDate >= 0 && strDate <= 9) {
             strDate = "0" + strDate;
         }
         var currentdate = year + seperator1 + month + seperator1 + strDate;
         return currentdate;
     }
