本文实例介绍了JavaScript时间操作之级联日期选择操作的详细代码，分享给大家供大家参考，具体内容如下
效果图：
具体代码：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB2312">
<title>年月日星期级联</title>
</head>
<body topmargin="10" leftmargin="0">
<form>
<select id=year onchange="toDate();">
<script>for(i=1970;i<=2010;i++)document.write("<option>"+i+"</option>")</script>
</select>
<select id=month onchange="toDate();">
<script>for(i=1;i<=12;i++)document.write("<option>"+i+"</option>")</script>
</select>
<select id=day onchange="toDay();"></select>
<input name=weekday>
</form>
<script type="text/javascript">
var arr="日一二三四五六".split("")
function toDate(){
with(document.all){
vYear=parseInt(year.options[year.selectedIndex].text)
vMonth=parseInt(month.options[month.selectedIndex].text)
day.length=0;
for(i=0;i<(new Date(vYear,vMonth,0)).getDate();i++){day.options[day.length++].value=day.length;day.options[day.length-1].text=day.length;}
}
toDay();
}
function toDay(){
vDay=parseInt(document.all.day.options[document.all.day.selectedIndex].value)
document.all("weekday").value="星期"+arr[new Date(vYear,vMonth-1,vDay).getDay()]
}
window.onload=toDate;
</script>
</body>
</html>
希望本文所述对大家学习javascript程序设计有所帮助。
