Ajax请求总是出错

Question

Actually i'm using CodeIgniter as backend in my project and jQuery 2.1.3 in my frontend.

<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

When i run this function:

var side = 'biltyveri';
var request_checkUrl = '/antibot/antibot_data?script=' + side;

$.ajax({
    url: request_checkUrl,
    type: "GET",
    dataType: 'json',
    beforeSend: function () {
        document.title = "Running...";
    },
    success: function (data) {
        document.title = "Success.";
        alert("success");
    },
    error: function (data) {
        alert("ERROR");
        console.log(data);
    }
});

Always displays ERROR and never displays the success function. I don't know what i'm doing wrong.

In my Controller i'm running this code:

echo $this->framework->ajaxJSONResponse(200, $data);

And this is the function it gives a response json:

function ajaxJSONResponse($status, $data) {
    header('Content-type: application/json');
    $response             = array();
    $response['status']   = $status;
    $response['data']     = $data;
    return json_encode($response);
}

The code above give a json response as follows:

{
    "status": 200,
    "data": {
        "text": "en TV",
        "images": [
            {
                "hash": "47a32df0c4b1f0b522e5faf35a46aacd95fe0ed4",
                "file": "ABImage_plane_1"
            },
            {
                "hash": "e11f83f4411364546329c8a8bf88da0dffd27029",
                "file": "ABImage_house_2"
            },
            {
                "hash": "93b4454ac09e7d7478fa2d25322e0e784370ea7a",
                "file": "ABImage_car_5"
            },
            {
                "hash": "36fac21a830b922edb507487d833556aeb9688f7",
                "file": "ABImage_clock_4"
            },
            {
                "hash": "cd1df47e052a5d0d50dab61b3e716339be0c6e68",
                "file": "ABImage_TV_3"
            },
            {
                "hash": "59e7f70b7874a500e576e25077adf254c52f5ee8",
                "file": "ABImage_train_4"
            }
        ]
    }
}

Thank you very much in advance.

EDIT: route:

$route['antibot/antibot_data'] = "antibot/antibot_interface_controller/antibot_data";

Background: ajax throwing error with right outcome

If you using Codeigniter, Your URL is wrong

var side = 'biltyveri';
var request_checkUrl = '/antibot/antibot_data?script=' + side;

This should come as

url: "<?php echo base_url()?>Controller_name/method_name",

and method should be post

type: "POST",

and pass data with

data : {"script : side, someOther: anotherValue"}

in controller method, Use this

$script = $_POST['script'];
$someOther = $_POST['anotherValue'];
