            $.ajax({
                type: "POST",
                url: "http://techcodesolutions.com/test/urlHostDemo/callHost.aspx/method",
                contentType: "application/json;charset=utf-8",
                dataType: "json",
                success: function (data) {
                    var b = data.d;
                    $("#lblMessage").text(b);
                },                    
                error: function (response) {
                    alert("no match");

Error found in developer console: `XMLHttpRequest` cannot load http://techcodesolutions.com/test/urlHostDemo/callHost.aspx/method. No `'Access-Control-Allow-Origin'` header is present on the requested resource. Origin 'null' is therefore not allowed access. — Saravana Kumar, Feb 20 '15 at 07:13
Where does this script present? Inside `techcodesolutions.com` or not? — Sarvap Praharanayuthan, Feb 20 '15 at 07:15

Your script must present inside `techcodesolutions.com` else you need to CORS will be the solutions. — Sarvap Praharanayuthan, Feb 20 '15 at 07:17
@ViswalingaSuryaS Sir i am calling the urlHostDemo/callHost.aspx web method from another file of local host and the script is present inside the local file — Sumeet Biswas, Feb 20 '15 at 07:21
Hi sumeet. You need to examine the arguments (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/arguments) to the error function (not just 'response') to get the full error. Further you can eye ball it if you use something like fiddler to watch the entire exchange. Hth — Andrew Hewitt, Feb 20 '15 at 07:25
Further. If you cut and paste that URL into your browser, what do you get back? — Andrew Hewitt, Feb 20 '15 at 07:26
You cannot do that. Either your script must present under `techcodesolutions.com` such as, `techcodesolutions.com/script.js` or CORS must be enabled. — Sarvap Praharanayuthan, Feb 20 '15 at 07:26
Thank you all of you. Now its working when i put my urlClientDemo file to the same server where urlClientDemo file is present — Sumeet Biswas, Feb 20 '15 at 07:26
i have one more question that here i deployed both file on same server but if i want to access my webmethod from different server could it possible that i just pass the webmethod url to ajax and i call the method? — Sumeet Biswas, Feb 20 '15 at 07:30
No. from `onedomain.com` to `anotherdomain.com` is not possible without CORS. — Sarvap Praharanayuthan, Feb 20 '15 at 07:43

Try executing this first, `PageMethod.method(alert);` is it showing a message or not? — Rashmin Javiya, Feb 20 '15 at 07:56
