使用该js只需要三个步骤:

1.通过<script language="javascript" src="js/editor.js" type="text/javascript""></script>引入该控件所在的文件;

2 调用browserControl()函数来判断客户端的浏览器类型,对不同的浏览器作不同的操作;

3. 调用newConfig()函数,将指定的textarea域设定为文本编辑区域.

经过该编辑器格式化的文字内容提交到数据库以后,从数据库中直接以字符串的格式取出来放在jsp页面中,就可以显示出原来发布时的 格式效果,这是因为javascirpt脚本已经对格式化文本做了特殊处理,比如加粗文字"[b]加粗"实际上存储的是"<b>加粗</b>"字符串。因此，显示页面无需作特殊处理，就可以恢复原文字的格式信息了。
