对比两个页面日期框的区别

　　在做一个项目开发过程中遇到一个问题，在一个页面中，单击input输入框时弹出一个日期选择控件（显示正常），但在另一个页面中就不能完全显示其控件，控件所在的层只有一半，但是宽度加宽了（样子像是把它横过来一样^_^）。在做这个的时候因为页面的格式和显示数据样式差不多，基本都是粘过来的。

　　这个问题郁闷了我两天，开始是认为页面中有对iframe或div的修改，可是没有找到。后来又检查其他的javascript脚本，也没有发现问题。之后就检查css样式表、检查日期控件... ...

　　这些都没有问题之后发现把成功页面中的输入框拷贝到不成功的页面中，那个输入框也不能正常显示了，反之则都可以正常显示，于是觉得应该和两个页面的某些设置有关系... ...

　　到最后都快把两个页面背下来了，都没有发现原因... ...

　　最后的方法，把两个页面分别拷贝下来，一行一行的去除代码，直道最后就剩下控件和form中的input输入框了，才找到原因，知道原因后想起了这两天的查找过程... ...

　　现在把它发上来大家也看看，争取别走我的弯路。一共三个文件，大家可以

　　日期控件，大家有需要的话可以拷下来用，单独的js文件：Calendar.js
