有什么意见，提一下。偶以后改进 ps:在FF2.0，ie6下测试没问题 为保证输入正确，记得给控件加个readonly /*********************************************************
* 使用方法
* 控件调用onclick="fPopCalendar(event,this,this)"
* 如下，给控件设置为readonly
* <input type="text" style="border:1px solid #cccccc;"
* size="15" onclick="fPopCalendar(event,this,this)"
* onfocus="this.select()" readonly="readonly" />
*
* 如果页面乱码，把下面包含汉字的定义项放到页面中即可
