请教高手：我想实现输入日期时，可以弹出一个日期框，任你选择，怎么实现？
可以参考这个网页中的“生日：”的输入方法。

取这个日历子程序Calendar.asp 并把它存放到你的程序目录下,取的方法:

IE浏览器→工具→Inernet选项→常规→设置→查看文件

找到Calendar.asp 把它复制到你的程序目录下(注意把文件名改成Calendar.asp)

然后用下面方法调用:

<script>
function fPopUpCalendarDlg(ctrlobj)
{
showx = event.screenX - event.offsetX - 4 - 10 ; // + deltaX;
showy = event.screenY - event.offsetY -168; // + deltaY;
newWINwidth = 210 + 4 + 18;

retval = window.showModalDialog("Calendar.asp", "", "dialogWidth:180px; dialogHeight:205px; dialogLeft:"+showx+"px; dialogTop:"+showy+"px; status:no; directories:yes;scrollbars:no;Resizable=no; " );
if( retval != null ){
ctrlobj.value = retval;
}else{
//alert("canceled");
}
}
</script>
input name="Birthday" size="20" readonly>
<input type="button" name="button_birthday" value=">>" onClick="fPopUpCalendarDlg(Birthday);return false">

把下面这个保存为：rili.asp，然后在其它的页面中用模式窗口调用这个文件就行了。
