Ajax jQuery调用不起作用

i'm trying to make a simple ajax request to the following URL. https://insightsoftwaresolutions.atlassian.net/rest/api/2/issue/createmeta?projectKeys=TES&issuetypeNames=Bug&expand=projects.issuetypes.fields

It receives the JSON response when i just put the URL on browser navigation bar and press enter but it's not working when i try to make a jquery ajax call. It's not having any console errors.

<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js'></script>

    <script>
        $(document).ready(function () {

            $.ajax({
                cache: false,
                type: 'GET',
                crossDomain: true,
                url: 'https://insightsoftwaresolutions.atlassian.net/rest/api/2/issue/createmeta?projectKeys=TES&issuetypeNames=Bug&expand=projects.issuetypes.fields',
                contentType: 'application/json; charset=utf-8',
                dataType: 'jsonp',

                success: function (data) {
                    alert("success");
                },
                    error: function (jqXHR, textStatus) {
                        //displayCallResults(jqXHR);
                        alert("error");
                    }
            });

        });
    </script>  

UPDATE:

I changed the datatype:'jsonp' to datatype:'json'. Then i get the following error.

Origin http://localhost:3029 is not allowed by Access-Control-Allow-Origin.

Your Server does not support JSONP. Either change that

OR

Add headers at nginx to support CORS on the server side. OR you can add the CORS header on server side.

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: *");

Once you do that you can access your code using simple

$.getJSON(url).done(function(response) {
    console.log(response); //here's your response
});
