一个非常漂亮的脚本日历

<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');
