<script>
window.onload = function(){
function getDate(){
debugger;
var today = new Date();
var date;
date = (today.getFullYear()) +"-" + (today.getMonth() + 1 ) + "-" + today.getDate() + "-" + today.toLocaleTimeString();
return date;
}
window.setInterval(function(){
document.getElementById("getBookTime").value=getDate();
}, 1000);
}
</script>
....
<input type="text" name="getBookTime" id="getBookTime" value="">
另外如何自定义日期格式如下：
选择日期：<input type="date" value="2011-01-04" /> 选择时间：<input type="time" value="22:52" /> 选择星期：<input type="week" /> 选择月份：<input type="month" />
结果如下：
选择日期：
选择时间：
选择星期：
选择月份：
另一种写法如下：
<html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312" /><title>系统时间</title><script language="javascript" type="text/javascript"><!-- //获得当前时间,刻度为一千分一秒 var initializationTime = (new Date()).getTime(); function showLeftTime() { var now = new Date(); var year = now.getYear(); var month = now.getMonth(); var day = now.getDate(); var hours = now.getHours(); var minutes = now.getMinutes(); var seconds = now.getSeconds(); document.all.show.innerHTML = "2" + year + "年" + month + "月" + day + "日 " + hours + ":" + minutes + ":" + seconds + ""; //一秒刷新一次显示时间 var timeID = setTimeout(showLeftTime, 1000); }//--></script></head><body onload="showLeftTime()"><label id="show">显示时间的位置</label><inpu type="text" value="这里是要获取时间的！"/></body></html>或者如下：
<html><head><title>无标题文档</title><script>function t(){var now= new Date();var h=now.getHours();var m=now.getMinutes();var s=now.getSeconds(); if (h>=0 && h <=12)var ho=" AM";if (h>12 && h<24)var ho=" PM";var tt=h+":"+m+":"+s+ho;document.getElementById("time").value=tt;}setInterval('t()',500);</script></head><body><form><input type="text" id="time" value=""/></form></body></html>
