一个表单日期输入的JS脚本
<script language=javascript>
var DS_x,DS_y;
function dateSelector() //构造dateSelector对象,用来实现一个日历形式的日期输入框。
{
var myDate=new Date();
this.year=myDate.getFullYear(); //定义year属性,年份,默认值为当前系统年份。
this.month=myDate.getMonth()+1; //定义month属性,月份,默认值为当前系统月份。
this.date=myDate.getDate(); //定义date属性,日,默认值为当前系统的日。
this.inputName=''; //定义inputName属性,即输入框的name,默认值为空。注意:在同一页中出现多个日期输入框,不能有重复的name!
this.display=display; //定义display方法,用来显示日期输入框。
}
function display() //定义dateSelector的display方法,它将实现一个日历形式的日期选择框。

var week=new Array('日','一','二','三','四','五','六');
