The <c:param> tag is used to specify parameters in the <c:url> tag and is related to URL encoding.
In the <c:param> tag, the name attribute indicates the parameter name, and the value attribute indicates the parameter value.
<c:param name="<string>" value="<string>"/>
The <c:param> tag has the following attributes:
| Attribute | Description | Is it necessary | Default value |
|---|---|---|---|
| name | The name of the parameter to be set in the URL | yes | none |
| value | Parameter Value | No | Body |
If you want to pass parameters to the <c:import> tag, you need to use the <c:url> tag to create the URL first:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
