I am currently working with a project, I have multiple select box in my application, each values should change according to the previous value selected in the first list, here is my code, i did not get the second select list.
Here is my jsp.
<s:form id="onSelectList" action="#">
<s:hidden id="c_country" name="buildingName" value="%{bean.building}"></s:hidden>
<s:hidden id="s_state" name="blockName" value="%{bean.block}"></s:hidden>
</s:form>
<s:hidden name="hospitalFloor.buildingName" id="c_country" ></s:hidden>
<s:url id="loadbuildingurl" action="loadbuildingforFloor"/>
<s:url id="loadstateurl" action="loadblockForFloor"/>
<s:url id="loadbuildingurl" action="loadbuildingforFloor"/>
<s:url id="loadstateurl" action="loadblockForFloor"/>
<textarea maxlength="200" name="hospitalBlock.blockDescription" id="blockDescription"></textarea>
<label class="tasks" style="vertical-align:top;"> Select Building :</label>
<sj:select tabindex="10"
id="docform_country"
cssClass="form-control input-sm"
href="%{loadbuildingurl}"
name="bean.country"
list="building"
onchange="loadValue();"
onSuccessTopics="s_countryList,s_countryList1"
onChangeTopics="c_countryList,c_countryList1"
deferredLoading="false"
headerKey="-1"
headerValue="select"
value="%{bean.country}">
</sj:select>
<label class="tasks" style="vertical-align:top;"> Block :</label>
<sj:select tabindex="10"
id="docform_state"
cssClass="form-control input-sm"
href="%{loadstateurl}"
name="bean.state"
list="block"
formIds="onSelectList"
onchange="loadValue();"
onSuccessTopics="s_stateList,s_stateList1"
onChangeTopics="c_stateList,c_stateList1"
reloadTopics="c_countryList"
deferredLoading="false"
headerKey="-1"
headerValue="select"
value="%{bean.state}">
</sj:select>
This is my struts.xml.
<action name="loadbuildingforFloor" class="hart.hospitalManagement.HospitalBuildingListForFloorAction">
<result name="success" type="json"></result>
</action>
<action name="loadblockForFloor" class="hart.hospitalManagement.HospitalBlockListForFloorAction" >
<result name="success" type="json"></result>
</action>
This is my java action class for second selected list.
package hart.hospitalManagement;
import hart.bean.HospitalFloor;
import hart.profilemanagement.DoctorRegistrationHelper;
import java.util.Map;
import com.opensymphony.xwork2.ActionSupport;
public class HospitalBlockListForFloorAction extends ActionSupport {
private Map<String, String> block;
private String buildingName;
private HospitalFloor hospitalfloor;
public Map<String, String> getBlock() {
return block;
}
public void setBlock(Map<String, String> block) {
this.block = block;
}
public String getBuildingName() {
return buildingName;
}
public void setBuildingName(String buildingName) {
this.buildingName = buildingName;
}
public String setBlockListForFloor()
{
HospitalFloorManagementHelper hospitalFloorManagementHelper=new HospitalFloorManagementHelper();
block=hospitalFloorManagementHelper.getBlockListForFloor(buildingName);
System.out.println("building Name are"+buildingName);
System.out.println("block list are"+block);
return SUCCESS;
}
public String getJSON()
{
return setBlockListForFloor();
}
}
This is the helper class.
public Map<String, String> getBlockListForFloor(String buildingName)
{
int buildingId=0;
Map<String, String> block=new HashMap<>();
DbConnect db=new DbConnect();
Connection con=db.returnConnection();
try
{
Statement stmt1=con.createStatement();
Statement stmt2=con.createStatement();
ResultSet rs1=stmt1.executeQuery("select buildingId from hospital_building where buildingName='"+buildingName+"'");
while(rs1.next())
{
buildingId=rs1.getInt("buildingId");
}
ResultSet rs2=stmt2.executeQuery("select blockName from hospital_block where buildingId='"+buildingId+"'");
while(rs2.next())
{
block.put(rs1.getString("blockName"), rs1.getString("blockName"));
}
}
catch(Exception e)
{
e.printStackTrace();
}
finally
{
db.closeConnection(con);
}
return block;
}
}
This is the bean class.
private String buildingName;
private String block;
public String getBuildingName() {
return buildingName;
}
public void setBuildingName(String buildingName) {
this.buildingName = buildingName;
}
But i can't get the second selected list, please anyone can help me? I am new in struts2.
