在layui中，新的頁面怎么獲取另一個頁面傳過來的數據,並可以對數據進行判斷，layui中的后台分頁（table）。

例如：打開一個新頁面的同時，傳數據。

layer.open({
    type: 2,
    title: '新增項目',
    shadeClose: false,
    shade: [0.3],
    maxmin: true, //開啟最大化最小化按鈕
    area: ['900px', '90%'],
    scrollbar: false, //屏蔽滾動條
    content: 'operate.html?type=add&buildingId=' + buildingId + '&businessId=' + businessId
});

=======================================


// 在新的頁面： 操作類型：add新增，edit修改，view查看
var operateType = QueryUtils.GetQueryString("type");

switch (operateType) {
    case "add":
        break;

　　case "edit":
        break;

　　case "view":
        break;

}


=======================================

這個是layui中的table分頁

table.render({
    elem: '#roomTable',
    url: '/room/json/',
    page: true,
    limit: 20,
    height: 'full-150',
    where: data,
    cols: [[
        {field: 'ROWNUM', fixed: true}
        /*, {field: 'ROOM_NAME', title: '名稱', width: 84}*/
        , {field: 'ROOM_NUM', title: '編號', width: 100}
        , {field: 'NAME', title: '項目類型', width: 100}
        , {field: 'ROOM_AREA', title: '面積(㎡)', width: 100}
        , {field: 'UNIT_NAME', title: '單元', width: 80}
        , {field: 'FLOOR_NAME', title: '樓層', width: 80}
        , {field: 'PROPERTY_RIGHT_TYPE', title: '產權所屬', templet: '#prorigTpl', width: 120}
        , {field: 'ROOM_INFO', title: '備注', width: 100}
        , {field: 'CREATE_NAME', title: '創建人', width: 120}
        , {field: 'CREATE_DATE', title: '創建時間', width: 180, align: 'center'}
        , {field: 'IS_OPEN', title: '是否開啟', templet: '#statusTpl', width: 100, align: 'center'}
        , {fixed: 'right', title: '操作', width: 360, align: 'center', toolbar: '#barDemo'}
    ]]
});

controller層：

 /**
  * 返回list 列表
  */
  @RequestMapping(value = "/json")
  @ResponseBody
  public Object json(Page page) {
  PageData pd = new PageData();
  Map<String, Object> map = new HashMap<String, Object>();
  List<PageData> varList;
      String datalayui = null;
//獲取當前登錄用戶
Subject currentUser = SecurityUtils.getSubject();
Session session = currentUser.getSession();
User user = (User) session.getAttribute(Const.SESSION_USER);
      try {
       //測試分頁 導出為layui的json數據
       pd = this.getPageData();
   pd.put("USER_ID", user.getUSER_ID());
       getPData(page, pd);//必填 2參
       varList = roomService.list(page);    //列出Building列表
       datalayui = getLData(page, varList);//必填 3參
      } catch (Exception e) {
       logger.error(e.toString(), e);
      } finally {
       logAfter(logger);
      }
          return datalayui;
}

   private String pageStr;       //最終頁面顯示的底部翻頁導航，詳細見：getPageStr();
   private PageData pd = new PageData();
