Doubleselect Tag (Form Tag) Example
In this section, we are going to describe the doubleselect
tag. The doubleselect tag is a UI tag that renders two HTML select elements
with second one changing displayed values depending on selected entry of first
one.
Add the following code snippet into the struts.xml file.
struts.xml
<action name="doubleselectTag">
<result>/pages/uiTags/doubleselectTag.jsp</result>
</action> |
Create a jsp using the tag
<s:doubleselect>
that renders two HTML select elements
with second one changing displayed values depending on selected entry of first
one. This tag contains various parameters:
The headerKey parameter sets the header key of
the second list. Must not be empty. In our case we have set it to"1"
The headerValue parameter sets the header value of
the second list. In our case we have set it to "--- Please Select ---"
The doubleName parameter sets the
name for complete component. In our case we have set it as : doubleName="dishes"
The doubleList sets the second iterable source to populate from. In our
case we have set it as :
doubleList="top == 'Color' ? {'Black','Green','White',
'Yellow','Red','Pink'} : { 'Apple','Banana','Grapes','Mango'}"
doubleselectTag.jsp
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Doubleselect Tag Example!</title>
</head>
<body>
<h1><span style="background-color: #FFFFcc">Doubleselect Tag Example!</span></h1>
<s:form>
<s:doubleselect label="Select Item"
headerValue="--- Please Select ---"
headerKey="1" list="{'Color','Fruits'}"
doubleName="dishes"
doubleList="top == 'Color' ? {'Black','Green','White',
'Yellow','Red','Pink'} : { 'Apple','Banana','Grapes','Mango'}" />
</s:form>
</body>
</html>

execute ur query.
then fetch the result into hash and keep it in list.
for ex.,
Execute Query :
SELECT COL1, COL2 FROM TBL;
create hash:
HashMap<String, String> resultMap =new HashMap();
store the query result into hash (resultMap)
then make select tag:
<HTML:SELECT list="resultMap" />
