获取当前阳历日期时间，阴历日期和星期，三者分开，可自行调整顺序。

新建JS文件getdates.js，代码如下：

/*获取当前阳历日期*/

function getCurrentDateTime () {

var d = new Date();

var year = d.getFullYear();

var month = d.getMonth() + 1;

var date = d.getDate();

/*时分秒*/

/**********************

var hours = d.getHours();

var minutes = d.getMinutes();

var seconds = d.getSeconds();

var ms = d.getMilliseconds();

**************************/

var curDateTime = year;

if (month > 9) {

curDateTime = curDateTime + "年" + month;

} else {

curDateTime = curDateTime + "年0" + month;

}

if (date > 9) {

curDateTime = curDateTime + "月" + date + "日";

} else {

curDateTime = curDateTime + "月0" + date + "日";

}

/**********************************

if (hours > 9){

curDateTime = curDateTime + " " + hours;

}else{

curDateTime = curDateTime + " 0" + hours;

}

if (minutes > 9){

curDateTime = curDateTime + ":" + minutes;

}else{

curDateTime = curDateTime + ":0" + minutes;

}

if (seconds > 9){

curDateTime = curDateTime + ":" + seconds;

}else{

curDateTime = curDateTime + ":0" + seconds;

}

***************************************/

curDateTime = curDateTime + " ";

return curDateTime;

}

/*获取当前是星期几*/

function showWeek () {

var show_week = new Array('星期一', '星期二', '星期三', '星期四', '星期五', '星期六', '星期日');

var time = new Date();

var day = time.getDay();

var now_week = show_week[day - 1] + ' ';
