如何在JSP上转义撇号或引号（由JavaScript使用）

使用Apache
StringEscapeUtils.escapeJavascript函数。

Escapes the characters in a String using Javascript String rules.Escapes any values it finds into their Javascript String form.Deals correctly with quotes and control-chars (tab, backslash, cr, ff,

etc.)

So a tab becomes the characters '\' and 't'.
