小程序获取 xx-xx 格式当前日期

getnowDate:function()
{
//获取当前日期的函数，setDate --- Date
var dates = new Date();
var year = dates.getFullYear();
var month = dates.getMonth()+1;
var hours = dates.getHours();
var ehours = (hours+1)%24;
var minute = dates.getMinutes();
if(minute<=9){
minute="0"+minute;
}
if(month<=9){
month = "0" + month
}
var day = dates.getDate();
if(day<=9){
day = "0"+day
}
var tDate = year+"-"+month+"-"+day;
var tTime = hours+":"+minute;
var eTime = ehours+":"+minute;
this.setData({
date:tDate,
starttime:tTime,
endtime:eTime
})
},
