JSTL: another for each and status
In this program we are declaring one array of type
String in which we are going to store some movies name in it. This declaration
will be done inside the scriptlet directive. Now set the attribute
by using the pageContext implicit object.
To retrieve the values set in
the directive we now use <c: forEach> tag which will help us to
iterate over the values. In this tag we have used some attributes like var
which will help us to iterate the values i.e. movies. The attribute items
helps us to get the attribute which we have set in the directive. The varStatus
attribute makes a new variable that holds an instance of javax.servlet.jsp.jstl.core.LoopTagStatus.
Use <c:out> to display the result to the
browser.
The forEach has one scoped variable called count.
The LoopTagStatus class has a count property which gives us the current
value of the iteration counter.
The code of the program is given below:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%
String[] movies = {"Sholay", "Maine Pyar kiya", "Jai Santoshi Maa", "Kaho Na Pyaar Hai", "Krish", "Rang De Basanti"};
pageContext.setAttribute("movies", movies, pageContext.PAGE_SCOPE);
%>
<html>
<head>
<title>forEach and status</title>
</head>
<body>
The forEach has one scoped variable called 'count', it tells the
current position of the element within the collection. <br>
<c:forEach var="movieName" items="${pageScope.movies}" varStatus="status">
Movie Number : <c:out value="${status.count}" /> is
<c:out value="${movieName}" /> <br />
</c:forEach>
</body>
</html> |
The output of the program is given below:
