Ajax Question

JSONP Parse Error with valid JSON Output

I am calling a Cross Domain AJAX Request using JSONP. Now, i am able to make it work using CORS. But, i want to know why it is not happening with JSONP. I looked at other threads with similar problem but couldnt figure out why it is not working in my case.

Here is the code:

type: "GET",
url: http://XXXX:8000/sap/bc/test_rest/jsonp_test?mode=S&ticket=123,
dataType: "jsonp",
jsonp: false,
jsonpCallback: "myJsonMethod",
success: function (data) {
error: function (httpReq, status, exception) {
alert(status + " " + exception);

Now, this calls my server, the data is populated and then i get an alert "parse error myJSONMethod was not called" on a callback URL http://xxxx:8000/sap/bc/test_rest/jsonp_test?mode=S&ticket=123&_=1470322282936

Additionally, in the console i get the error as Uncaught SyntaxError: Unexpected token :
The response structure is:

{"ROOT":{"CONTRACT":"40002356","ITEM":"000010","KUNNR":"0000004676","NAME":"REALTY EXECUTIVES","NET_PRICE":19.95,"GROSS_PRICE":19.95,"MATNR":"144","SQFEET":""}}

When i run this JSON Output on jsonlint it says it is a valid JSON. I don't know where the JSON is getting messed up.

Your data must be like this to be valid for JSONP:

myJsonMethod({"ROOT":{"CONTRACT":"40002356","ITEM":"000010","KUNNR":"0000004676","NAME":"REALTY EXECUTIVES","NET_PRICE":19.95,"GROSS_PRICE":19.95,"MATNR":"144","SQFEET":""}});
