示例
以下示例说明了fn：fn:join（）函数的功能-
<%@ taglib uri = "http://java.sun.com/jsp/jstl/core" prefix = "c" %>
<%@ taglib uri = "http://java.sun.com/jsp/jstl/functions" prefix = "fn" %>
<html>
<head>
<title>Using JSTL Functions</title>
</head>
<body>
<c:set var = "string1" value = "This is first String."/>
<c:set var = "string2" value = "${fn:split(string1, ' ')}" />
<c:set var = "string3" value = "${fn:join(string2, '-')}" />
<p>Final String : ${string3}</p>
</body>
</html>
上面的代码将产生以下结果-
Final String : This-is-first-String.
