JSONP parse error with jquery ajax request

Question

I have the following jquery ajax request:

jQuery.ajax({
    url: serverAddress+'php/product.php',
    type: 'GET',
        jsonpCallback: "callback7",
        dataType: 'jsonp',
        data: sendInfo,
    success: function(result)
            {
                alert(result);
                //do something
            },
    error:function(jqXHR,msg,errorThrown){ alert(msg+" : "+errorThrown);}
  });

on the server side the script is:

$callback = $_GET['callback'];
//do something
$result = //something
echo $callback.'('.json_encode($result).')';

I get the following error from the ajax call:

parseerror : callback7 was not called

I looked up this error but couldn't find anything relevant, either in SO or in google... Hope you can help me. Thanks!

EDIT: I eventually solved the problem by transforming it into a regular json request. I'll be happy to know what could be the problem ans solution nevertheless.

Answer 1

Try adding these name value pair as jsonp:false & crossDomain:true in your js file. And in your server side remove the line $_Get['callback'] and add echo $callback.'('.json_encode($result).')' and alse set $callback='callback7'
