Set Tag (Data Tag) Example

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 settag 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" %>



<html>

  <head>

  <title>Set Tag (Data Tag) Example!</title>

  </head>

  <body>

  <h1><span style="background-color: #FFFFcc">Set Tag 

  
(Data Tags) Example!</span></h1>

  <s:set name="technologyName" value="%{'Java'}"/>

  Technology Name: <s:property value="#technologyName"/>

  </body>

</html>

Output of the setTag.jsp:
