我的一段JS中有个${}字符，是一个正则表达式中的，并且在...中，但这样的JSP编译就通不过，JAVA错如下:
org.apache.jasper.JasperException: /alert.jsp(10,3932) "${}" contains invalid expression(s): javax.servlet.jsp.el.ELException: Encountered "}", expected one of [, , , "true", "false", "null", "(", "-", "not", "!", "empty", ]

奇怪了，一个JS语法怎么会引起JAVA报错呢，谁知道这个问题怎么解决?
页首加上<%@ page isELIgnored＝"true"%>
这个是EL表达式啊，你在JS中写可以加一下转义符看看
