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 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" %>
<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>
