Combobox Tag (Form Tag) Example
In this section, we are going to describe the combobox
tag. The combo box is basically an HTML INPUT of type text and HTML SELECT grouped together to give you a combo box functionality. You can place text in
the INPUT control by using the SELECT control or type it in directly in the text
field.
Add the following code snippet into the struts.xml
file.
struts.xml
<action name="comboboxTag" class="net.roseindia.comboboxTag">
<result>/pages/uiTags/comboboxTag.jsp</result>
</action> |
Create a list in the action class and populate it
with various items as shown in the " comboboxTag"
class.
comboboxTag.java
package net.roseindia;
i mport com.opensymphony.xwork2.ActionSupport;
import java.util.*;
public class comboboxTag extends ActionSupport{
private List fruits;
public String execute()throws Exception{
fruits = new ArrayList();
fruits.add("Apple");
fruits.add("Mango");
fruits.add("Orange");
fruits.add("Pine Apple");
return SUCCESS;
}
public List getFruits(){
return fruits;
}
}

Create a jsp using the tags <s:combobox>
The tag <s:combobox label="Colors Name" name="colorNames" headerValue="--- Please Select ---"
headerKey="1" list="{'Black','Green','White','Yellow','Red','Pink'}" />
prints a combobox with name color Name
and an HTML INPUT of type text and HTML SELECT grouped together
created using the list.
The tag <s:checkboxlist name="Animals-name" list="animals" />
prints a combobox with
name Fruits Name
and an HTML INPUT of type text and HTML SELECT grouped together created using
the "fruits" list of the
action class "checkboxlistTag".
