前台取后台传回来的值

web项目

1.放在ModelMap内传到后台，页面使用${}接收，如${page.results}

--controller  

@RequestMapping(value = { "/carrier/getPage" }, method = { RequestMethod.GET ,RequestMethod.POST})
public String getPage(ModelMap model, @ModelAttribute Page<Bean> page,Bean bean) throws Exception {

   try {
      ***Consumer.getCarrierPage(page,bean);
      getUrl(model);
   } catch (ScnException e) {
      model.addAttribute("exception",e);
      return JspViews.ERROR_PAGE;  //显示错误信息
   }
   model.addAttribute("page", page);
   model.addAttribute("searchBean", bean);
   return "***/***List";
}

--页面使用${}接收，${page.results}

<div class="row">
   <div class="col-xs-12">
      <div class="row">
         <div class="col-xs-12">
            <div id="chenkbox">
               <table id="sample-table-2" class="table table-bordered">
                  <thead class="fixedHeader" >
                  <tr>
                     <td class="tc min-10">
                        <label class="position-relative">
                           <input type="checkbox"class="ace allcheck" /><span class="lbl allchecklbl"></span>
                        </label><span>全选</span>
                        <div class="ww"></div></td>
                     <td class="tc min-5" sort="string"><span>序号</span>
                        <div class="ww"></div></td>
                     <td class="tc min-20" sort="string"><span>用户名</span>
                        <div class="ww"></div></td>
                     <td class="tc min-20" sort="string"><span>密码</span>
                        <div class="ww"></div></td>
                  </tr>
                  </thead>
                  <tbody class="scrollContent" id="tests" >
                  <c:forEach items="${page.results}" varStatus="status" var="bean">
                     <tr>
                        <td class="min-10 td_center">
                           <label class="position-relative">
                              <input type="checkbox"class="ace" value="${bean.id}" id="checkbox"
                                    name="checkbox" /><span class="lbl"></span>//隐藏值id
                           </label><span>&emsp;&emsp;</span></td>
                        <td class="min-5 td_center">
                              ${status.index+1 }
                        </td>
                        <td class="min-20 td_center">${bean.name}</td>
                        <td class="min-20 td_center">${bean.pwd}</td>
                     </tr>
                  </c:forEach>
                  </tbody>
               </table>
            </div>
         </div>
      </div>
   </div>
</div>

2.@ResponseBody返回具体某一类型的数据

--controller  

@RequestMapping(value = "/po/selectByNumber" , method = {RequestMethod.GET , RequestMethod.POST })
@ResponseBody
public Bean selectPoByPonumber(HttpServletResponse response,Bean bean) throws Exception{
   try {
      String number = bean.getNumber();
      return ***Consumer.selectByNumber(number);
   } catch (ScnException e) {
      return null;
   }
}

--页面
$.ajax({

   url:"../po/selectByNumber",
   data : {'number':id},
   type : "get",
   success : function(data) {// ajax返回的数据
      $("#update_number").val(data.number);
      $("#update_name").val(data.name);
   }
});

--controller  

@RequestMapping(value = "/**/selectDetails" , method = {RequestMethod.GET , RequestMethod.POST })
@ResponseBody
public List<Map<String, Object>> selectDetails(ModelMap model,@RequestParam(value="number")String number) throws Exception{
   List<Map<String,Object>> result = null;
   try{
       result = ***Consumer.selectDetails(number);
   }catch(Exception e){
      throw new RuntimeException();
   }
   return result;
}

--页面使用$.each(res,function(i,data){});遍历list

$.ajax({
    url:"../***/selectDetails",
    data : {'number':id},
    type : "get",
    error : function(msg) { //若Ajax处理失败后返回的信息
        SimplePop.alert("入库单明细失败！");
    },
    success : function(res) {// ajax返回的数据

          var str = '';
　　　　　　$.each(res,function(i,data){
    　　　　　　str += '<tr>';
    　　　　　　str += '<td class="tc min-5 td_center">'+ ++i +'</td>';
    　　　　　　str += '<td class="tc min-15 td_center" name="number" >'+nullShows(data.number)+ '</td>';
    　　　　　　str += '<td class="tc min-15 td_center" name="name" >'+nullShows(data.name)+ '</td>';
    　　　　　　str += '</tr>';
　　　　　　});

    }
});

Rest项目

1.放在JsonResult内传到后台

--controller  

@POST
@Path("/selectPrintData/{number}")
@Produces("application/json")
@Override
public JsonResult selectPrintData(@PathParam("packedboxnumber")String number, @HeaderParam("sessionId")String sessionId){
   JsonResult result = JsonResult.createFalied("数据为空");
   SystemUserInfoT u = CacheUtils.get(SystemUserInfoT.class, sessionId);
   if (u == null || u.getAccount() == null) {
      result=JsonResult.createSuccess();
      result.setMsg("用户信息为空");
      result.setReturnCode(-1);
      result.addData("");
      return result;
   }
   Map<String, Object> reqMap = new HashedMap();

   try{
      reqMap.put("number",number);
      List<Bean> detail = ***Consumer.selectDetail(reqMap);
      result.addData(detail);
   }catch(Exception e){
      result.setMsg(e.getMessage());
      result=JsonResult.createFalied(e.getMessage());
      result.setReturnCode(-1);
      result.addData("");
   }
   return result;

--页面使用${}接收，${page.results}

$.ajax({
   type:"POST",
   dataType:"json",
   url:'selectPrintData'+'/'+number,
   data: null,
   success : function(result) {// ajax返回的数据
      var list = result.data;
　　　　console.log(list);

       var number = '';
       $.each(list,function(i,item){
           $.each(item,function(j,obj){
               if(j==0){
                   number += obj.number==null?'':obj.number;
　　　　　　　　　}
           });
       });

   },
   error : function(msg) { //若Ajax处理失败后返回的信息
      layer.alert("查询明细数据失败！");
   }
});
