如果需要完整文件可以点击下面的链接下载.
Calendar.txt 下载后改名为 Calendar.js
CalendarDemo.txt 改名为 Calendar.htm
用浏览器打开Calendar.htm 即可.(暂时只支持 IE 浏览器, FireFox显示出来后无法选择年月.)
希望大家多提意见 :)
下面是我自己写的日期控件--Calendar.js 文件内容.
/* Auther: Nicholas.Meng Date: 2005-07-17 Version: 1.01 控件上用到的颜色都作为变量放在前面,可以根据自己需要修改. 设计思想: 为每个需要日期控件的输入框加一个它自己的日期控件,即一个<Div></Div>. 刚创建的时候只赋上id,class等值,并且把它的位置固定在输入框的下方。这是日期控件只是一个空白层。 显示的时候只向其中填内容而不需要再调整日期控件的位置。 有效的避免了当浏览器窗口大小改变之后,使用getBoundingClientRect()只能得到控件相对位置,导致的日期控件错位的问题. 并且就算用户没有点击按钮显示出日期控件.也只是增加了一个隐藏的空白层而已. 如何调用: 首先,使用日期控件的文本框一定要赋上id 和 name 并且在网页中均不可重复。 主要方法:showCalendar( 文本框 , 日期控件的id ); 例如: <input type="text" id="txtDateFrom" name="txtDateFrom"> <input type='Button' name="btnSchDaFr" οnclick="showCalendar( txtDateFrom , 'dcDateFrom')"> 之后,在网页代码的最末端加上如下代码: <script> createNewDiv( document.getElementById( 'txtDateFrom') , 'dcDateFrom' ); </script> Tips: 1.当需要多个日期控件时,所有的日期控件的 id 在网页中均不能重复. 2.所有的日期控件DIV 都属于 Calendar class. 可以在网页的<Style></Style>中做出字体等设置,例如: <style> .Calendar { font-size:12px; font-family:"Arial","sans-serif"; } </style> */ var iCalendarHeight = 150;
