In this section, we are going to describe the Set tag. The set tag is a generic tag that is used to assign a value to a variable in a specified scope. It is useful when you wish to assign a variable to a complex expression and then simply reference that variable each time rather than the complex expression.
Add the following code snippet into the struts.xml file.
struts.xml
| <action name="setTag"> <result>/pages/genericTags/setTag.jsp</result> </action> |
Now create a jsp page using <s:set>
tag as shown in the setTag.jsp
page. The set
tag is used to assign a value to a variable in a specified
scope. The parameters name and value in the tag <s:set name="technologyName" value="%{'Java'}"/>
acts as the name-value pair. Here we set the parameters as
name="technologyName" value="Java".
setTag.jsp
<%@ taglib prefix="s" uri="/struts-tags" %>
|
Output of the setTag.jsp:
![]() |
