3. HashMap和JSONObject用法

<%@page import="net.sf.json.JSONObject"%>
<%@page import="java.util.List"%>
<%@page import="java.util.ArrayList"%>
<%@page import="java.util.HashMap"%>

String sql = "select b.CardCode,b.cardname from Wbtx_Tkhjbxx b where b.id in (select distinct a.wbtx_tkhjbxx_id from wbtx_Tkhjbxx_YWYXX a where a.xsy = "+UserContext.getContext().getUser().getId()+")";
String cusCode = "";
String cardname="";
List list=new ArrayList();
List list1=new ArrayList();
ApexRowSet rs_1 = null;
rs_1 = ApexDao.getRowSet(DataAccess.getDataSource(), sql);
while(rs_1.next()){
　　HashMap<String, Object> sh=new HashMap<String, Object>();
　　JSONObject node = new JSONObject();
　　cusCode = rs_1.getString("CardCode");
　　cardname = rs_1.getString("cardname");
　　sh.put("cusCode",cusCode);
　　sh.put("cardname",cardname);
　　node.put("cusCode",cusCode);
　　node.put("cardname",cardname);
　　list.add(sh);
　　list1.add(node);
}
request.setAttribute("list",list);
request.setAttribute("list1",list1);

<%
for(int i=0;i<list.size();i++){
　　HashMap hm=(HashMap)list.get(i);
%>
　　<option value="<%=hm.get("cusCode") %>"><%=hm.get("cardname") %></option>
<%
}
%>

//js中

var contactorList = <%=request.getAttribute("contactorList")%>;

for(var i in contactorList) {
　　var khdm=contactorList[i].khdm;
　　var contactor=contactorList[i].contactor;
　　if(khdm == v_cusCode) {
　　　　var option = document.createElement("option");
　　　　option.innerHTML=contactor;
　　　　option.value=khdm;
　　　　select2.appendChild(option);
　　}
}
