I wrote a calendar two years ago, but the compatibility was not good. I re-wrote it this time.
Compatible with multiple browsers
I learned a lot about it, especially about W3C standardization.
For example, FF and IE have different understandings of the box model
box.style{width:100;border 1px;}
ie understands it as box.width = 100
ff understands it as box.width = 100 1*2 = 102
You can use this method to allow both browsers to browse normally
box.style{width:100!important; width /**/:120px;border 1px;}
Note width (space)/**/

/***********************
* 创建对象 var c = new Calendar("c"); document.write(c);
* 调用方法 c.show(arg1,arg2,arg3)
* 参数1: 文本输入框(必填). 如 onfocus="c.show(this)";
* 参数2: 按钮或其它可用单击事件的HTML元素(如果使用按钮方式则必填).
如 onclick="c.show(this,c.getObjById(*))" *=文本输入框名称
* 参数3: 如果没有文本框没有值则使用该值初始化日历(选填).
如 onfocus="c.show(this,'2006-01-01')
* 注: 参数顺序不分先后. MSIE6/Opera8/FireFox1.5 下测试通过
