ColdFusion 9,JSON和jQuery EasyUI

Question

我正在尝试向JSON输出ColdFusion查询,以便它可以与jQuery EasyUI(特别是Datagrid)一起使用.

从EasyUI附带的示例.json文件中,这是他们正在寻找的格式......

{"total":2
  , "rows":[ 
            { "productid":"FI-SW-01"
              , "productname":"Koi"
              , "unitcost":10.00
              , "status":"P"
              , "listprice":36.50,"attr1":"Large"
              , "itemid":"EST-1"
             }
          , { "productid":"K9-DL-01"
             , "productname":"Dalmation"
             , "unitcost":12.00 
             , "status":"P"
             , "listprice":18.50
             , "attr1":"Spotted Adult Female"
             , "itemid":"EST-10"
            }
        ]
 }

但是,当我SerializeJSON(emails)在ColdFusion查询上使用时,我得到了这个:

{ "COLUMNS":["CUSTOMERID","CUSTOMERFIRSTNAME"]
   , "DATA":[
               [101,"Bhavin"],[102,"Frank"]
            ]
}

这似乎不被EasyUI认可,所以我猜问题是(1)EasyUI是否能够识别和使用ColdFusion的输出,如图所示,或者(2)有没有办法让ColdFusion输出JSON in像EasyUI示例中包含的格式？

更新:

这是我使用serializeQueryByColumns参数时的样子:

{ "ROWCOUNT":83
  , "COLUMNS":["CUSTOMERID","CUSTOMERFIRSTNAME"]
  , "DATA":{
            "CUSTOMERID":[101,102]
            ,"CUSTOMERFIRSTNAME":["Bhavin","Frank","]
            }
}

但仍然没有被EasyUI识别.在他们的文档中,他们显示了一个看起来像这样的php示例,所以我想尝试使用ColdFusion复制它的输出我想:

$rs = mysql_query('select * from users');
$result = array();
while($row = mysql_fetch_object($rs)){
    array_push($result, $row);
}

echo json_encode($result);

谢谢!

loadFilterdatagrid 的功能可以将任何数据转换为可以加载到datagrid中的标准数据格式.

<script>
var data = { "ROWCOUNT":83
  , "COLUMNS":["CUSTOMERID","CUSTOMERFIRSTNAME"]
  , "DATA":{
            "CUSTOMERID":[101,102]
            ,"CUSTOMERFIRSTNAME":["Bhavin","Frank"]
            }
};
function myLoadFilter(data){
    var result = {total:data.ROWCOUNT};
    var rows = [];
    var count = data.DATA[data.COLUMNS[0]].length;
    for(var i=0; i<count; i++){
        var row = {};
        $.map(data.COLUMNS, function(field){
            row[field] = data.DATA[field][i];
        })
        rows.push(row);
    }
    result.rows = rows;
    return result;
}
</script>

datagrid组件可以声明为:

    <table class="easyui-datagrid" title="Basic DataGrid" style="width:700px;height:250px"
        data-options="
            singleSelect:true,
            collapsible:true,
            data:data,
            loadFilter:myLoadFilter
        ">
    <thead>
        <tr>
            <th data-options="field:'CUSTOMERID',width:100">CUSTOMERID</th>
            <th data-options="field:'CUSTOMERFIRSTNAME',width:200">CUSTOMERFIRSTNAME</th>
        </tr>
    </thead>
</table>
