This post helps you understand and use the <c:remove> tag in the JSTL core tags library with code example.

The <c:remove> tag removes a scoped variable from its scope. We can specify the scope from where the variable to be removed. If no scope is provided, the variable will be removed from all the scopes.

 

JSTL <c:remove> Syntax:

<c:remove var="<string>" scope="<string>"/>

 

Attributes:

Name	Required	Type	Description
var	True	java.lang.String	Name of the scoped variable to remove from scope.
scope	False	java.lang.String	Scope where the variable can be found. (Optional)
