Calling web service from code behind instead of javascript

I have a javascript code that calls a web service from another server, it's working, but i need to call it from code behind due to an http call request issue, following my code :
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "http://10.8.111.12:7181/CatchEventLink.asmx/CollectDataLink",
data: JSON.stringify({ "pDataDictionnary": lDataCollected }),
dataType: "json",
async: true,
success: function (data, textStatus) {
if (textStatus == "success") {
//alert('success');
}
},
error: function (exception) {
//alert('Exeption : ' + exception);
}
});
Any suggestions please??

ajax request not working in google chrome - net::ERR_INCOMPLETE_CHUNKED_ENCODING

I have a plain html page and I write some javascript code that use jquery ajax request. The ajax request sends to server successfully in firefox and IE, but does not work in google chrome! When the ajax request sent, chrome console shows net::ERR_INCOMPLETE_CHUNKED_ENCODING error. I don't know How can I solve this strange problem. Here is my ajax code:
var data = {};
data['type'] = "email";
data['value'] = "test#gmail.com"
$.ajax({
headers: {
Accept: "application/json; charset=utf-8",
"Content-Type": "application/json; charset=utf-8"
},
type: "POST",
url: "/testUrl",
data: JSON.stringify(data),
contentType: "application/json; charset=utf-8",
dataType: "json",
async: false,
success: function(result) {
alert("success");
},
error: function(data) {
alert("error");
},
failure: function(errMsg) {
alert("failure");
}
});
I tested plain ajax request with XMLHttpRequest javascript object, but also has above problem.

HTTPS issue with ajax call in javascript

I am calling a webservice using ajax call(javascript) to return json.It is working fine.But when i changed my site to HTTPS it is not working.What will be the reason?
function GetReportguid1, callback) {
$.ajax({
type: "POST",
url: "/demo/Datapage.aspx/GetData",
contentType: "application/json; charset=utf-8",
dataType: "json",
data: JSON.stringify({
guiddemo: guid1
}),
success: function (results) {
callback(results);
},
error: AjaxFailed
});
};

Add the Access-Control-Allow-Origin header from the server
Access-Control-Allow-Origin: https://www.yoursite.com
http://en.wikipedia.org/wiki/Cross-Origin_Resource_Sharing
And try use JSONP instead.

AJAX success call back not working

Here is the code I am using to access my web API controller named Owner; the success function is not being called. Any ideas?
$.ajax({
type: "GET",
url: 'http://localhost:26533/api/Owner',
contentType: "application/json",
dataType: "jsonp",
success: function (response) { alert("yes"); }
});

Remove the contentType and dataType and check the response..
Here an example:
$.ajax({
type: 'GET',
url: 'http://localhost:26533/api/Owner',
success: function(data){
alert(data);
},
error: function(xhr, type, exception) {
// if ajax fails display error alert
alert("ajax error response type " + type);
}
});
With this you can see what's wrong...

Response/callback for JSONP using jQuery $.ajax not working

I am unable to catch response from C# to jQuery using $.ajax. I get an error "SCRIPT ERROR". How can I catch response using JSONP? This is what i am using:
$.ajax({
async: true,
context: mrq,
cache: false,
type: "GET",
url: MYURL,
crossDomain: true,
dataType: 'jsonp',
data: MYDATA,
processData: false,
jsonp: "jsonREQ",
jsonpCallback: "onJSONPsuccess",
success: function (jsonText, textStatus) {}
});

As far as I understand, dataType: 'jsonp' means that as soon as it's returned it's put into the callback function as an argument. So, I'd try this:
onJSONPsuccess = function(response) {
// do something with response, e.g.
results = response["results"]
}
$.ajax({
crossDomain: true,
dataType: 'jsonp',
data: { /*params you're sending in*/ },
jsonp: "jsonREQ",
jsonpCallback: "onJSONPsuccess",
success: onJSONPsuccess
});

You say the server side is C# - are you using WCF? There's a great article here about it:
http://bendewey.wordpress.com/2009/11/24/using-jsonp-with-wcf-and-jquery/
Basically you need to set up WCF (or whatever server-side code you're using) to return the json wrapped in a call to your callback function.
However, with jquery, you can simply add "?Callback=?" to your URL, change the dataType to 'jsonp', and forget about the rest of that stuff. You don't need the jsonp or jsonpCallback options set.
In contrast to a json request, the jsonp request will return your data not wrapped in a 'd' property, so your call back function is:
function(data) { var a = data.myProperty ... }
rather than
function(data) { var a = data.d.myProperty ... }
and the whole method is along the lines of:
var url = configuration.serviceUrl + "/" + method + "?callback=?";
var options = {
type: 'GET',
url: url,
data: args,
dataType: "jsonp",
contentType: "application/json",
success: function(data) {
if (callback != null) callback(data);
}
};
if (typeof errorCallback != 'undefined')
options.error = errorCallback;
$.ajax(options);
