如何在网页中添加系统时间

Date date = new Date()

var year = date.getYear()

var month = date.getMonth()

var day = date.getDay()

var nowDate = year + "-" + month +"-"+day

然后将这个变量值放在html中的span或者其他控件，如果需要动态显示时间，需要使用setTimeout()方法并且在方法内部继续调用方法，这样会一直调用显示。

是的，只能用代码，不用代码还能用什么？

先把鼠标定义在你想要显示时间的单元格中，然后切换到代码插入以下代码

<script language=JavaScript>

<!-- document.write

now = new Date()

document.write

if (now.getDay() == 5)document.write("星期五")

if (now.getDay() == 6)document.write("星期六")

if (now.getDay() == 0)document.write("星期日")

if (now.getDay() == 1)document.write("星期一")

if (now.getDay() == 2)document.write("星期二")

if (now.getDay() == 3)document.write("星期三")

if (now.getDay() == 4)document.write("星期四")

document.write

</script>

<script lange=JavaScript>

<!--tmpDate=newDate()

date=tmpDate.getDate()

month=tmpDate.getMonth()+1

year=tmpDate.getYear()

document.write("今天是：")

document.write(year)

document.write("年")

document.write(month)

document.write("月")

document.write(date)

document.write("日")

</script>
