JSTL - Core <c:remove> Tag

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 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 the 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" %>

      <p>Before Remove Value: <c:out value = "${salary}"/></p>
         <c:remove var = "salary"/>
      <p>After Remove Value: <c:out value = "${salary}"/></p>

The above code will generate the following result −
