无法从Yii中的响应ajaxLink获取json

Question

I have a ajaxLink what send request to controller, where I return encoded json string:

return CJSON::encode(array(
            'up' => ...,
            'down' => ...,
        ));

In view, ajaxLink attributes:

'dataType' => 'json',
'success'  => 'js: function(data) {
     console.log(data); // equal to null
 }'

What I am doing wrong ?

Answer 1

Try this:

header('Content-type: application/json');
echo CJSON::encode(array(
            'up' => ...,
            'down' => ...,
        ));
