js 获取当前时间 YYYY-MM-DD hh:mm:ss

function CurentTime(){
var now = new Date();

var year = now.getFullYear(); //年
var month = now.getMonth() + 1; //月
var day = now.getDate(); //日

var hh = now.getHours(); //时
var mm = now.getMinutes(); //分
var ss = now.getSeconds(); //秒

var clock = year + "-";

if(month < 10)
clock += "0";

clock += month + "-";

if(day < 10)
clock += "0";

clock += day + " ";

if(hh < 10)
clock += "0";

clock += hh + ":";
if (mm < 10) clock += '0';
clock += mm + ":";

if (ss < 10) clock += '0';
clock += ss;
return(clock);
