代码二

//定义时钟显示的函数

function displayTime()

{

var today = new Date()// 定义日期对象

var hours = today.getHours()

var minutes = today.getMinutes()

var seconds = today.getSeconds()

// 从日期对象中中获得时间信息

minutes = fixTime(minutes)

seconds = fixTime(seconds)// 引入fixTime（）函数，使分和秒可以正常显示，对于小于10的数字则在该数字前加一个0

//将时间字符串组合在一起并写出

var the_time = hours + ":" + minutes + ":" + seconds

window.document.the_form.the_text.value = the_time//把表格的值重新写一遍，相当于刷新时间

the_timeout= setTimeout('displayTime()',500)//每半秒钟执行一次该函数,即500毫秒

}

function fixTime(the_time)

{

if (the_time <10)

{

the_time = "0" + the_time

}

return the_time

}

</script>
