我正在尝试使用 JQGrid 和 Codeigniter 做一个网格，我需要一个 JSON 响应，所以我可以把它放在我的网格上，但是我从控制器得到了一个非常奇怪的响应：
�������������{"page":"1","total":1,"records":6,"rows":[{"cell":["I01- 01","789456123"]},{"cell":["I01-01","113990035"]},{"cell":["I01-01","112680010"]},{"cell":["MA-0329-1","789456123"]},{"cell":["MA-10001","789456123"]},{"cell":["MA-10001","12345"]}]}
正如你所看到的，我得到的是 JSON，但带有所有这些烦人的符号。我已经使用返回了我的输出
$this->output->set_content_type('application/json')->set_output(json_encode($responce));
但问题还在继续。任何人都知道如何摆脱这些符号？下面是我的代码：
看法：
$(document).ready(function (){
jQuery("#list").jqGrid({
url: 'http://localhost/ProyectoNetbeans/CodeIgniter_2.1.3/index.php/Asignados_controller/loadData',
mtype : "post", //Ajax request type. It also could be GET
datatype: "json", //supported formats XML, JSON or Arrray
colNames:['Grupo','Expediente'], //Grid column headings
colModel:[
{name:'grupo', index:'grupo', width:150, editable:true, edittype:'text'},
{name:'expediente', index:'expediente', width:150, editable:true, edittype:'text'}
],
pager: '#pager',
rowNum:10,
rowList:[15,30],
sortname: 'grupo',
reloadAfterSubmit: true,
sortorder: 'asc',
viewrecords: true,
postData: {numero:"grupo"},
caption: 'Asignados',
}).navGrid('#pager',{edit:false,add:false,del:true},
{//EDITAR
},
{//AGREGAR
},
{// DELETE
},
{multipleSearch : false}, // enable the advanced searching
{closeOnEscape:true} /* allow the view dialog to be closed when user press ESC key*/
);
});
控制器：
function loadData()
{
$page = isset($_POST['page'])?$_POST['page']:1;
$limit = isset($_POST['rows'])?$_POST['rows']:10;
$sidx = isset($_POST['sidx'])?$_POST['sidx']:'grupo';
$sord = isset($_POST['sord'])?$_POST['sord']:'';
$start = $limit*$page - $limit;
$start = ($start<0)?0:$start;
$where = "";
$searchField = isset($_POST['searchField']) ? $_POST['searchField'] : false;
$searchOper = isset($_POST['searchOper']) ? $_POST['searchOper']: false;
$searchString = isset($_POST['searchString']) ? $_POST['searchString'] : false;
/**************************/

return $result;

if ($_POST['_search'] == "true") {

}

$responce->rows[$i]['cell']=array($row->grupo,$row->expediente);
$i++;
}
$this->output->set_content_type('application/json')->set_output(json_encode($responce));
}
模型：
function getAllData($start,$limit,$sidx,$sord,$where){
$this->db->select('expediente,grupo');
$this->db->limit($limit);
if($where != NULL)
$this->db->where($where,NULL,FALSE);
$this->db->order_by($sidx,$sord);
$query = $this->db->get('asignado',$limit,$start);
return $query->result();
}
非常感谢任何帮助。
