$.ajax({
                        type: 'POST',
                        url: '<%= ResolveUrl("~/api/Chile/Point/Retrieval") %>',
                        data: JSON.stringify(paras),
                        contentType: 'application/json',
                        beforeSend: function () {
                            $("#btnRetrieval").attr({ disabled: "disabled" });
                        },
                        success: function (msg) {
                            $("#btnRetrieval").removeAttr("disabled");
                            if (msg.IsSuccess) {
                                //$("#modalConfirmated").modal();
                                window.location.href = "<%= ResolveUrl(CMSContext.GetUrl(OkUrl)) %>";
                            } else {
                                $("#modelFailedText").html(msg.Message);
                                $("#UpdateModalFailed").modal({ backdrop: 'static' });
                            }
                        }
                    });

• type (default: 'GET')
  Type: String
  An alias for method. You should use type if you're using versions of jQuery prior to 1.9.0.

 

• url (default: The current page)
  Type: String
  A string containing the URL to which the request is sent.

 

• data
  Type: PlainObject or String or Array
  Data to be sent to the server. It is converted to a query string, if not already a string. It's appended to the url for GET-requests. See processData option to prevent this automatic processing. Object must be Key/Value pairs. If value is an Array, jQuery serializes multiple values with same key based on the value of the traditional setting (described below).

 

• contentType (default: 'application/x-www-form-urlencoded; charset=UTF-8')
  Type: Boolean or String
  When sending data to the server, use this content type. Default is "application/x-www-form-urlencoded; charset=UTF-8", which is fine for most cases. If you explicitly pass in a content-type to $.ajax(), then it is always sent to the server (even if no data is sent). As of jQuery 1.6 you can pass false to tell jQuery to not set any content type header. Note: The W3C XMLHttpRequest specification dictates that the charset is always UTF-8; specifying another charset will not force the browser to change the encoding. Note: For cross-domain requests, setting the content type to anything other than application/x-www-form-urlencoded, multipart/form-data, or text/plain will trigger the browser to send a preflight OPTIONS request to the server.

• beforeSend
  Type: Function( jqXHR jqXHR, PlainObject settings )
  A pre-request callback function that can be used to modify the jqXHR (in jQuery 1.4.x, XMLHTTPRequest) object before it is sent. Use this to set custom headers, etc. The jqXHR and settings objects are passed as arguments. This is an Ajax Event. Returning false in the beforeSend function will cancel the request. As of jQuery 1.5, the beforeSend option will be called regardless of the type of request.

• success
  Type: Function( Anything data, String textStatus, jqXHR jqXHR )
  A function to be called if the request succeeds. The function gets passed three arguments: The data returned from the server, formatted according to the dataType parameter or the dataFilter callback function, if specified; a string describing the status; and the jqXHR (in jQuery 1.4.x, XMLHttpRequest) object. As of jQuery 1.5, the success setting can accept an array of functions. Each function will be called in turn. This is an Ajax Event.
