$.ajax and JSONP. ParseError and Uncaught SyntaxError: Unexpected token :

Question

First of all, I\'ve been looking for the answer to my problem in several topics and I couldn\'t find a solution that works with my code.

I\'m trying to get the answe

Answer 1

First off you have a typo in your success parameter; you missed the ending s. Also, when you are performing a JSONP request you need to return your JSON information in JSONP format; which should include the callback token as part of the return string. A sample JSONP string would look likes this:

yourcallbacktoken({"id":3,"login":"pepe","key":"0D1DBA4BE87E02D43E082F9AA1ECFDEB"})

Take a look at this page for more information on the JSONP specifications: http://devlog.info/2010/03/10/cross-domain-ajax/

Answer 2

succes : function(data){

That's a typo:

success : function(data){

Answer 3

If you are using jsonp then the syntax is wrong

You need to return

myJsonMethod({"id":3,"login":"pepe","key":"0D1DBA4BE87E02D43E082F9AA1ECFDEB"});

and also add to your ajax request options

jsonp: false,
jsonpCallback: "myJsonMethod"

so

$.ajax({
    type : "Get",
    url :"http://XXXZZZ/Servlet/Login",
    data :"login="+login+"&password="+pass,
    dataType :"jsonp",
    jsonp: false,
    jsonpCallback: "myJsonMethod",
    success : function(data){
        alert(data);},
    error : function(httpReq,status,exception){
        alert(status+" "+exception);
    }
});

(and of-course fix the success as @voyager noted)
