js 时间date格式化

js中没有类似java中的DateFormat类来处理日期格式化，可以自己写一个：
var newDate=new Date();
var year=newDate.getFullYear();
var month=(newDate.getMonth()+1)<10?"0"+(newDate.getMonth()+1):newDate.getMonth()+1;
var day=newDate.getDay()<10?"0"+newDate.getDay():newDate.getDay();
var hours=newDate.getHours()<10?"0"+newDate.getHours():newDate.getHours();
var minuts=newDate.getMinutes()<10?"0"+newDate.getMinutes():newDate.getMinutes();
var seconds=newDate.getSeconds()<10?"0"+newDate.getSeconds():newDate.getSeconds();
document.write(year+"-"+month+"-"+day+" "+hours+":"+minuts+":"+seconds);
显示结果：2016-07-01 15:21:39

var newDate = new Date();
        $scope.dateStr =newDate.getFullYear() + "-" + ((newDate.getMonth() + 1) < 10 ? "0" : "") + (newDate.getMonth() + 1) + "-" + (newDate.getDate() < 10 ? "0" : "") + newDate.getDate();
        $scope.nowNewDate = new Date($scope.dateStr.replace(/-/g, '/'));

-- 标准时间
var beginDate = Date.parse($cookies.get('newBeginTime'));
-- 时间戳
               var beginDateStamp = new Date(beginDate);
-- 2016-11-11
               $scope.beginDate = beginDateStamp.getFullYear() + "-" +
                  ((beginDateStamp.getMonth() + 1) < 10 ? "0" : "") +
                  (beginDateStamp.getMonth() + 1) + "-" +
                  (beginDateStamp.getDate() < 10 ? "0" : "") + beginDateStamp.getDate();
