* 功能描述:本日历控件(以下简称控件)采用隐藏层的实现方式，避免了弹出窗口式可能被浏览器拦截的麻烦。
* 控件的调出函数被触发后，在指定位置会弹出控件面板。向文本框输入数据时，先要选择日期，然后用鼠标
* 点击面板上某一天的单元格。这时，日历控件会把你选择的时间自动填到文本框里。控件面板最上面显示的是
* 年和月。可以按住键盘上的↑,↓,←,→来分别调整年和月；也可以点击面板最下面一栏，"Today"按钮两侧
* 的<<,<,>,>>来调整年和月。如果点击"Today"按钮，则会把当前时间传给文本框。从上至下第二栏的"日，
* 一，二，三，四，五，六"表示的是星期，不做日期输入，只用来提示时间；如果用鼠标按住此栏，可以托拽
* 控件到页面任意位置。星期栏下面是控件主操作区，用鼠标点击某一天，即可把选中的时间传给指定文本框。
* 主操作区下面显示的是时分秒，用鼠标点击时分秒其中任意一个数字均会显示相应的微调按钮，以便调整时间。
* 回填给文本框的日期，目前支持以下几种：yyyyMMddHHmmss,yyyyMMdd,yyyy-MM-dd HH:mm:ss,yyyy-MM-dd,
* yyyy/MM/dd HH:mm:ss,yyyy/MM/dd,yyyy年MM月dd日HH时mm分ss秒,yyyy年MM月dd日
*
* 调用方法:
* 方法一:calendar()，该函数适合直接由文本框调用。
* 方法二:calendar(obj,format)，该函数适合由任意指定的页面元素调用。其中参数obj为输出的目标，format
* 为输出的日期格式。
*
* 因为本日历控件的图片使用的是相对路径，所以因页面所在文件夹的不同有可能图片显示不出来，
* 这时请修改图片相对路径: this.imageRelativePath = "/pageComponent/resources/images/calendar";
*
