给你看一下我以前写过的这个例子吧：
<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<meta name="GENERATOR" content="Microsoft FrontPage 4.0">
<meta name="ProgId" content="FrontPage.Editor.Document">
<title>日期选择</title>
<Script>
function addDays()
{
var febdates,yearPart,monthPart,i,strHTML;
yearPart=parseInt(document.all.bYear.value);
monthPart=parseInt(document.all.bMonth.value);
i=1;
strHTML="<select name='bDay' id='bDay' size='1'>";
while (monthPart==1 || monthPart==3 || monthPart==5 || monthPart==7 || monthPart==8 || monthPart==10 || monthPart==12)
{
while (i<=31)
{
strHTML= strHTML + "<option value='"+i+"'>"+i+"</option>";
i++;
}
strHTML=strHTML + "</select>";
selection.innerHTML=strHTML;
break;
}
while (monthPart==4 || monthPart==6 || monthPart==9 || monthPart==11)
{
while (i<=30)
{
strHTML= strHTML + "<option value='"+i+"'>"+i+"</option>";
i++;
}
strHTML=strHTML + "</select>";
selection.innerHTML=strHTML;
break;
}
while (monthPart==2)
{
if (yearPart % 4==0 && yearPart % 100 !=0 || yearPart % 400==0)
febdates=29;
else
febdates=28;
while (i<=febdates)
{
strHTML= strHTML + "<option value='"+i+"'>"+i+"</option>";
i++;
}
strHTML=strHTML + "</select>";
selection.innerHTML=strHTML;
break;
}
}
</Script>
</head>

<body>
<table>
<tr>
<td>出生日期：
<form name="frmdate">
<select name="bYear" size="1" id="bYear" onchange="addDays();">
<Script>
date=new Date();
tYear=date.getYear();
i=tYear-25;
document.write("<option></option> ");
while (i<=tYear)
{
document.write("<option value=\""+i+"\">"+i+"</option>");
i++;
}
</Script>
</select>
年
<select name="bMonth" id="bMonth" size="1" onchange="addDays();">
