请教一个日期选择框的问题

西秦月影 发布于 2009-09-03 09:46， 580 次点击
我在网上搜到这么一段javascript，是用户注册的时候提交出生日期的那种动态选择框，但是用户选择好并提交的后台以后，我在servlet里如何拿到这个出生日期的属性值啊？我javascript学的不好，请教高手如何获取属性，非常感谢。
源码如下：
                    <script language="javascript">

                      this.month=myDate.getMonth()+1;
                      this.date=myDate.getDate();
                      this.inputName='time';
                      this.display=display;
                    }

                        var Y=obj.clientTop;

                    }
                    </script>
                    
                    
<form action="" method="get" name="tomatoform01">
<script language="javascript">
var myDate = new dateSelector();
myDate.year;
myDate.inputName='time';
myDate.display();
</script>
<input name="" type="submit" value="提交" onclick="cheak()" />
</form>
js里input的name为“time",其实名字你可以改的
