Calling Action on OnChange event of Drop Down List with Struts2

Last week I was having problem with drop down onchange event on strut project. I wanted to load some data to Drop down list according to another item in a drop down list when it is changed. Finally I found this way as the solution with JavaScript. Within the JSP page can be called any Struts Action using JavaScript function. I have mentioned some of sample code regarded to all steps.

Class Diagram for the scenario:-

Code sample for “VIEW” (createSchedule.jsp):-

---- JavaScript Code ----

<script type="text/javascript">

function onTypeChange() {

document.scheduleForm.action = 'loadCourcesForType.action';

document.scheduleForm.submit();

}

</script>

---- HTML Code ----

<s:select name="sch.course.courseTypes.typeId"

list="#session.crsTypes"

listKey="typeId"

listValue="typeName"

onchange="onTypeChange()" />

<s:select name="sch.course.courseId"

list="#session.courses"

listKey="courseId"

listValue="courseName" />

Code sample for STRUTS XML:-

<action name="loadCourcesForType"

method="loadCoursesForType"

class="com.abc.struts.action.ScheduleAction" >

<result name="success"&gt createSchedule.jsp </result&gt

</action>

Code sample for ACTION class (ScheduleAction.java):-

public String loadCoursesForType() {

// Load Courses to Session

courses = get courses due to the selected course type (as sch.getxxx(selected_type))

session.put("courses", courses);

return "success";

}
