你好我一直在这个工作了近2个小时了。我似乎无法找到关于结果不显示在jqGrid上的错误。我试着回显json_encode并显示出来。我的jqGrid正在我的本地网站上工作，但没有在现场。我传递一个参数，以便它不会显示其他未包含的项目。jqGrid无法在Live网站上工作
这里就是我的了：
//控制器
function all ($eid)
{
$page = isset($_POST['page'])?$_POST['page']:1;
$limit = isset($_POST['rows'])?$_POST['rows']:10;
$sidx = isset($_POST['sidx'])?$_POST['sidx']:'rank';
$sord = isset($_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']) ? $_POST['searchString'] : false;
if (isset($_POST['_search']) == 'true') {
$ops = array(
'eq'=>'=',

);
foreach ($ops as $key=>$value){
if ($searchOper==$key) {
$ops = $value;
}
}
if($searchOper == 'eq') $searchString = $searchString;
if($searchOper == 'bw' || $searchOper == 'bn') $searchString .= '%';
if($searchOper == 'ew' || $searchOper == 'en') $searchString = '%'.$searchString;
if($searchOper == 'cn' || $searchOper == 'nc' || $searchOper == 'in' || $searchOper == 'ni') $searchString = '%'.$searchString.'%';
$where = "$searchField $ops '$searchString'";
}
if(!$sidx)
$sidx =1;
//$this->db->where('event_id', $eid);
$count = $this->db->count_all_results('table1');
if($count > 0) {
$total_pages = ceil($count/$limit);
} else {
$total_pages = 0;
}
if ($page > $total_pages)
$page=$total_pages;
$query = $this->Manager_model->getcontentfromtable($start,$limit,$sidx,$sord,$where, $eid);
$responce->page = $page;
$responce->total = $total_pages;
$responce->records = $count;
$i=0;
foreach($query as $row) {
$responce->rows[$i]['rank']=$row->rank;

$i++;
}
echo json_encode($responce);

有什么错误信息？只有说“不工作”的问题没有显示尽职调查。跨域问题？ – 2012-02-16 02:35:58
没有错误信息。不显示结果。 – 2012-02-16 02:39:06
我建议你总是在jqGrid定义中包含'loadError'回调函数（更多信息见[答案]（http://stackoverflow.com/a/6969114/315935））。此外，还可以将答案附加在服务器的完整JSON响应中。您可以使用[Fiddler]（http://www.fiddler2.com/fiddler2/）或[Firebug]（http://getfirebug.com/）来捕获HTTP流量。另外，检查HTTP标题中的“Content-Type”很重要。它必须是“application/json”。所有信息将显示问题的根源是在服务器还是在客户端部分。 – Oleg 2012-02-16 07:02:08
