原本准备在上一篇中直接修改的，无奈编辑功能太差，打开一堆html代码，空格“ ”都看的人眼花缭乱，只好另开一篇。
升级说明：添加了针对一个界面多个职能提示位置的设定，只需修改文本框onfocus="fnStartInterval(this,'DropDownList2')"，
设置好相应的参数即可，同时修复了在IE6下div无法遮盖下拉列表的问题，（IE6下无论如何设置select的z-index或div的z-index属性均无济于事），关于这个就是利用了一个iframe，将其盖在div要显示的位置，然后div再放在iframe上方即可。即使下方有select元素，也没关系了。下面是最新code：
复制代码 代码如下:
