把js new Date转换成想要的时间 yyyy-mm-dd

var mytime = new Date();
var formatDateTime = function (date) {
var y = date.getFullYear();
var m = date.getMonth() + 1;
m = m < 10 ? ('0' + m) : m;
var d = date.getDate();
d = d < 10 ? ('0' + d) : d;
var h = date.getHours();
var minute = date.getMinutes();
minute = minute < 10 ? ('0' + minute) : minute;
return y + '-' + m + '-' + d+' '+h+':'+minute;
};
var myTime= formatDateTime(mytime)
