两年前写过一个日历,可是兼容性不好.这次重新写了一次.兼容多种浏览器了解了不少东东，特别是对于W3C标准化．如FF和IE对box模型的理解不同box.style{width:100;border1px;}ie理解为box.width=100ff理解为box.width=100+1*2=102可以使用这种方法使两种浏览器都
两年前写过一个日历,可是兼容性不好.这次重新写了一次.
兼容多种浏览器
了解了不少东东，特别是对于W3C标准化．
如FF和IE对box模型的理解不同
box.style{width:100;border1px;}
ie理解为box.width=100
ff理解为box.width=100+1*2=102
可以使用这种方法使两种浏览器都可以正常浏览
box.style{width:100!important;width/**/:120px;border1px;}
注意width(空格)/**/

/***********************
*创建对象varc=newCalendar("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
