"xmlHttpRequest cannot load" error occur if i remove..can you please provide fiddle link for that... — Pradeep Kumar, Oct 16 '16 at 05:01
That would be the same-origin policy, the URL doesn't send CORS headers. — adeneo, Oct 16 '16 at 05:04
@Div did u get data from that ajax post..please check with console its throwing error.. — Pradeep Kumar, Oct 16 '16 at 05:09
@PradeepKumar Can you please add that in the question as snippet — Divyang Desai, Oct 16 '16 at 05:21
@PradeepKumar, Okay, you get cross origin error, and for that you can refer [this](http://stackoverflow.com/questions/25310450/cross-origin-resource-sharing-cors-concept) — Divyang Desai, Oct 16 '16 at 05:42
If you removed the dataType='jsonp', you will get the following error: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://fiddle.jshell.net' is therefore not allowed access. The response had HTTP status code 501. This means the service is using CORS and your origin is not included in the list of allowed sites to make an ajax request from another domain — Haitham Shaddad, Oct 16 '16 at 05:46

it seems that you cant build the URL string inside the JSON

instead of creating it in the JSON like this:

url: Url + '&callback=?',

you can just add it to the end of the original URL string:

var Url = "https://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/ajaxGetQuoteJSON.jsp?symbol=LIBERTSHOE&callback=?'";

http://codepen.io/nilestanner/pen/pEOgZj

This removes the syntax error although codepen still shows a cross origin error.

@PradeepKumar this new error is not the same error that you posted about, We would need more information about the API you are using, and possibly needs to be asked in a separate question. – Niles Tanner Oct 16 '16 at 05:18

I hope this solves the issue.

  

      $(document).ready(function() {
        var Url = "https://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/ajaxGetQuoteJSON.jsp?symbol=LIBERTSHOE&callback=?";
        $.ajax({
            contentType: 'application/json',
            dataType: 'json',            
            url: Url            
        }).then(function(data){
            //What should happen in success scenarios
            console.log('Success');
            alert(data)
        },function(data){
            //what should happen in failure scenarios
            console.log('Failure Block');
            alert(data)
        });
    });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
