JS 显示系统时间。

?

函数如下：

<SCRIPT LANGUAGE="JavaScript">
<!--
var myDate = new Date();
  myDate.getYear(); //获取当前年份(2位)
  myDate.getFullYear(); //获取完整的年份(4位,1970-????)
  myDate.getMonth(); //获取当前月份(0-11,0代表1月)
  myDate.getDate(); //获取当前日(1-31)
  myDate.getDay(); //获取当前星期X(0-6,0代表星期天)
  myDate.getTime(); //获取当前时间(从1970.1.1开始的毫秒数)
  myDate.getHours(); //获取当前小时数(0-23)
  myDate.getMinutes(); //获取当前分钟数(0-59)
  myDate.getSeconds(); //获取当前秒数(0-59)
  myDate.getMilliseconds(); //获取当前毫秒数(0-999)
  myDate.toLocaleDateString(); //获取当前日期
  var mytime=myDate.toLocaleTimeString(); //获取当前时间
  myDate.toLocaleString( ); //获取日期与时间

//-->

</SCRIPT>

测试通过的实用函数如下：

function getCurrentTime() {

	today = new Date();
	var separate = "/";

	var year = today.getFullYear();
	var month = today.getMonth() + 1;
	var date = today.getDate();

	var hour = today.getHours();
	var minute = today.getMinutes();
	var second = today.getSeconds();

	var ymd;
	var time;

	if (month < 10) {
		month = "0" + month;
	}

	if (date < 10) {
		date = "0" + date;
	}

	ymd = year + separate + month + separate + date;

	if (hour < 10) {
		hour = "0" + hour;
	}

	if (minute < 10) {
		minute = "0" + minute;
	}

	if (second < 10) {
		second = "0" + second;
	}

	time = hour + ":" + minute + ":" + second;
	
	return (ymd + " " + time);

}
