The <c:remove> tag removes a variable from either a specified scope or the first scope where the variable is found (if no scope is specified). This action is not normally particularly helpful, but it can aid in ensuring that a JSP cleans up any scoped resources it is responsible for.
The <c:remove> tag has following attributes:
Attribute | Description | Required | Default |
---|---|---|---|
var | Name of the variable to remove | Yes | None |
scope | Scope of the variable to remove | No | All scopes |
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <html> <head> <title><c:remove> Tag Example</title> </head> <body> <c:set var="salary" scope="session" value="${2000*2}"/> <p>Before Remove Value: <c:out value="${salary}"/></p> <c:remove var="salary"/> <p>After Remove Value: <c:out value="${salary}"/></p> </body> </html> |
This would produce following result:
Before Remove Value: 4000 After Remove Value: |
