function getNowDateFormate(now){

strTime = now.toLocaleString();

strYear = now.getYear();

strMonth = now.getMonth();

strDay = now.getDay();

displayTime = strYear +"/"+strMonth+"/"+strDay;

if(strTime.substring(5,6)<10){

var displayTime = strTime.substring(0,4)+"-0"+strTime.substring(5,6)+"-"+strTime.substring(7,9);

}else{

var displayTime = strTime.substring(0,4)+"-"+strTime.substring(5,7)+"-"+strTime.substring(8,10)

};

return displayTime;
