//This method will do AJAX call to a webmethod.

//How to set parameters 

//Parameters:

//PsTargetURL: This parameter specifies the URL of webpage / webservice to be called.

//PsTargetMethodName: This parameter specifies the method name to be executed on webservice / webpage.

//PobjData: This is a JSON object. This object contains data to be passed as parameter to server function. 

//If Server method has no parameters then just send null to this function

//PonSuccess: Method name to execute on successful execution of AJAX request.

//PonFailed: Method name to execute if execution of AJAX request failed.

//type: specified as “POST” to do POST requests. Setting POST allows us to send large amount of data (big JSON objects).

//data: Data specifies the JSON data to be sent to server. We are using JSON objet. This data object needs to serialize before sending it to the server.

//contentType: we are using is application/json with utf-8 character set.

//dataType: is set to JSON as we are sending JSON object.

// In this method, If there is no data to be sent to the server, then specify “{}” in data parameter. It will act as no parameters.

// While sending data as parameters to the server method care must be taken that:

// The parameter names given to server method must match to the parameter names given in JSON object.

//Example:

//Var JSONObj = {

// A: 10, b: 100

//}

//Then on server, method must be defined as:

//[webMethod]

//Public static MethodName(int A, int b)

//{

//}
