html:select用法的一个例子- -

                                      

 

model部分:
package com.appeon.manager.form;
 
import java.util.ArrayList;
 
/**
  * 网关id、name对Form
  */
public class GatewayListForm {
      private ArrayList gatewayList;
      private String gatewayId; 
     
      public String getGatewayId() {
            return gatewayId;
      }
      public void setGatewayId(String gatewayId) {
            this .gatewayId = gatewayId;
      }
      public ArrayList getGatewayList() {
            return gatewayList;
      }
      public void setGatewayList(ArrayList gatewayList) {
            this .gatewayList = gatewayList;
      }
}
 
Action部分:
            // 得到地区代码并填充到指定的form中去
            GatewayListDAO dao = new GatewayListDAO();
            ArrayList list = dao.getGatewayList();
            int length = list.size();
            ArrayList gateways = new ArrayList();
            boolean isFirst = true ;
            String gatewayId = "" ;
           
            for ( int i = 0; i < length; i ++) {
                  Object[] gateway = (Object[])list.get(i);
                  gateways.add( new LabelValueBean((String)gateway[1], (String)gateway[0]));
                  if (isFirst) {
                        gatewayId = (String)gateway[0];
                        isFirst = false ;
                  }
            }
            GatewayListForm gwForm = new GatewayListForm();
            gwForm.setGatewayList(gateways);
            gwForm.setGatewayId(gatewayId);
            request.setAttribute( "gatewayListForm" , gwForm);
 
JSP部分:
        < html:select  styleId = "column" name = "gatewayListForm" property = "gatewayId">
         < html:optionsCollection name="gatewayListForm" property="gatewayList"/>
        </ html:select>
另一段代码:
          <html:select property="taskIds" multiple="multiple" size="8">
           <html:options collection="taskCollection" property="id" labelProperty="title"  />
          </html:select>
