Javascript 插入 UBB标签 到表单 文本域 函数 及演示 By shawl.qiu

Subject: Javascript 插入 UBB标签 到表单 文本域 函数 及演示 By shawl.qiu

摘要: 
本文演示了使用 JS函数 动态插入 UBB 标签到 表单文本域的操作.
本文并没有演示进行 UBB 标签转换为 HTML 标签的操作

说明:
HTML编辑器需要ActiveX支持, 并不是所有浏览器都支持, 比如Opera. 

因此对于HTML编辑器和UBB编辑器, 两者我选择 UBB, 因为鄙人习惯使用 OPERA 浏览器, 写的东西当然也得适用于Opera.

话外音: 使用Opera会上瘾, 定力不足者不可乱试:)
