上次说到当前台页面需要加载多个数据类，而前台页面只有一直一个form表单，那我们该如何进行数据回显。
为了解决这个问题，小组成员就讨论能不能把数据返回给页面而不是返回给表单，于是就有了以layer（web弹层组件）进行多个表单提交，多个表单数据回显的开发模式。
来看看原先前台页面
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>

在这个jsp里面
我们可以看到，这个页面中包含了model以及form，如果要换成layer弹出框，那么我们就需要把model跟form单独择开来
这里我就以housebase举例
加入layer的js
点击新增
showmodel()对应的js
function showmodel(){
$.post(‘housebase/addoreditpage.do‘, {dTypeCode:"19,26,32,33,30,9"}, function(str){
layer.open({
title: ‘房屋数据新增‘,
type: 1,
maxmin:true,
shade: 0,
area:‘1100px‘,
content: str //注意，如果str是object，那么需要字符拼接。
});
});
}
再来看看housebase/addoreditpage.do对应的Controller，这就是解决返回值的关键，获取不同的实体类，通过model.addAttribute传到houseBase_model页面,然后在前台用美元符号取值
@RequestMapping(value="addoreditpage")
public String toAdd(HttpServletRequest req,Model model,Long updateid){
/*判断update是否为空，若不为空，进行数据回显*/
if(updateid!=null){
/*通过主键ID获得房屋位置信息实体类对象*/
HousePosition hp= housePosService.selectByPrimaryKey(updateid);
/*把对象传回model*/
model.addAttribute("hPos", hp);
/*通过主键ID获得房屋信息实体类对象*/
HouseInfo hi = houseInfo.selectByForeignKey(updateid);
/*把对象传回model*/
model.addAttribute("hInfo", hi);
/*通过主键ID获得户主基本信息实体类对象*/
HouseOwner ho = houseOwner.selectByForeignKey(updateid);
/*把对象传回model*/
model.addAttribute("hOwn", ho);
}
return "house/model/houseBase_model";
}
这个的hinfo就是model.addAttribute("hInfo", hi);中的hInfo
Controller返回的是对应的model页面，
在model中利用<%@include file=" "%>包含了三个不同的form表单元素
这是其中一个表单。
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<div id="houseOwner" class="form-horizontal">
<input type="hidden" name="hOwn.id" value="${hOwn.id}" />
<div class="form-group">
<label class="col-sm-2 control-label" for="name">户主姓名</label>
<div class="col-sm-4">
<input type="text" class="form-control" name="hOwn.oName" value="${hOwn.oName}" placeholder="">
</div>
<label class="col-sm-2 control-label" for="cardtype">证件类型</label>
<div class="col-sm-4">
<select id="oCardtype" name="hOwn.oCardtype" class="form-control">
<c:forEach var="value" items="${combox9}">
<option value="${value.dCode}" <c:if test="${value.dCode==hOwn.oCardtype}">selected</c:if>>${value.dName}</option>
</c:forEach>
</select>
</div>
</div>
<div class="form-group">
<label class="col-sm-2 control-label" for="cardnum">证件号码</label>
<div class="col-sm-4">
<input type="text" class="form-control" name="hOwn.oCardnum" value="${hOwn.oCardnum}"
placeholder="">
</div>
<label class="col-sm-2 control-label" for="contact">联系方式</label>
<div class="col-sm-4">
<input type="text" class="form-control" name="hOwn.oContact" value="${hOwn.oContact}"
placeholder="">
</div>
</div>
</div>
