我很新玩并开始使用play 2.0。

试图查看 jqgrid 但无法显示数据，下面是代码：

控制器 ：

public static Result userLogs(String criteria) throws JSONException {
    JSONObject responcedata = new JSONObject();
    JSONArray logData = UserLogs.getUserlogs();
    responcedata.put("page", 1);
    responcedata.put("records", 10);
    responcedata.put("rows", logData);
    response().setContentType("application/json");
    return ok(userlogs.render(responcedata));    
}

模型类：

公共静态 JSONArray getUserlogs() {

    String query = "select date from user where user_id=1 and resp=1";
    List<SqlRow> userLogs = Ebean.createSqlQuery(query).findList();
    JSONArray cellarray = new JSONArray();
    int tableSize = userLogs.size();
    int i = 0;
    while (i < tableSize) {
        JSONObject cellObj = new JSONObject();
        JSONArray cell = new JSONArray();

        cell.put(i + 1);
        cell.put(userLogs.get(i).getTimestamp("date"));
        try {
            cellObj.put("cell", cell);
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        cellarray.put(cellObj);
        i++;
    }
    return cellarray;
}

看法 ：

jQuery("#grid").jqGrid({

    url:"@Application.userLogs(),
    datatype : 'json',
    colNames:['S.No','date'],
    colModel:[
        {name:'sno',index:'sno', width:50, sorttype:"int"},
        {name:'date',index:'date', width:150, sorttype:"date"}
              ],    
      jsonReader : {                   
        root: "rows",  
        page: "page", 
        total: "total", 
        records: "records",                   
        cell: "cell", 
        loadOnce: "true",
        id: "id",
        userdata: "userdata"
      },
      width: 900,  
      height: 220,
      rowNum:10, rowList:[10,20,30],   
      pager: '#pager',
      sortname: 'id',
      viewrecords: true,  
      gridview: true,
      sortorder: "desc",  
      loadonce:true,
      ignoreCase:true,
      multiselect: true,
         });
});

以下是例外::

请让我知道如何处理这种情况并使用 jqgrid 在视图中显示列表。实现这一目标的任何替代方法也有帮助。

谢谢..！！！
