使用JSP和Java Bean来构建一个网上书店。本章介绍的例子可以分成两大部分

<%@ page contentType="text/html;charset=utf-8"%>
<%@ include file="../include.jsp"%> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<select name="d_city" id="d_city">
  <option value="0" selected>选择城市</option>
<%
long tcity = StringUtil.getLong(request,"city");
DBRow city[] = memberMgr.getAreaByParentid(StringUtil.getLong(request,"pid"));

for (int i=0; i<city.length; i++)
{
%>
                            <option value="<%=city[i].getString("id")%>" <%=tcity==city[i].get("id",0l)?"selected":""%>> 
                            <%=city[i].getString("title")%>
                            </option>
<%
}
%>
</select>
