JSTL Core <c:forEach> Tag
JSTL Core <c:forTokens> Tag
These tags exist as a good alternative to embedding a Java for, while, or do-while loop via a scriptlet. The <c:forEach> tag is the more commonly used tag because it iterates over a collection of objects. The <c:forTokens> tag is used to break a string into tokens and iterate through each of the tokens.
Attribute:
The <c:forEach> tag has following attributes:
Attribute | Description | Required | Default |
items | Information to loop over | No | None |
begin | Element to start with (0 = first item, 1 = second item, ...) | No | 0 |
end | Element to end with (0 = first item, 1 = second item, ...) | No | Last element |
step | Process every step items | No | 1 |
var | Name of the variable to expose the current item | No | None |
varStatus | Name of the variable to expose the loop status | No | None |
The <c:forTokens> tag has similar attributes as <c:forEach> except one additional attribute delims which specifies sharacters to use as delimiters.
Attribute | Description | Required | Default |
delims | Characters to use as delimiters | Yes | None |
Example for <c:forEach>:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<title><c:forEach> Tag Example</title>
</head>
<body>
<c:forEach var="i" begin="1" end="5">
Item <c:out value="${i}"/><p>
</c:forEach>
</body>
</html>
|
This would produce following result:
Item 1
Item 2
Item 3
Item 4
Item 5

<c:forTokens items="Zara,nuha,roshy" delims="," var="name">
