function getNowTime(){
var now = new Date();
var year = now.getFullYear();
var month = now.getMonth() + 1;
var day = now.getDate();
if (month < 10) {
month = '0' + month;
};
if (day < 10) {
day = '0' + day;
};
// 如果需要时分秒，就放开
// var h = now.getHours();
// var m = now.getMinutes();
// var s = now.getSeconds();
var formatDate = year + '-' + month + '-' + day;
return formatDate;
