Asynchronous call to WebService / WCF using JQuery

In one of the implementations, we had to do asynchronous calls to multiple SharePoint Lists for better UI and user experience.

For better performance and managed solution, we exposed a custom web service which takes care of all the data manipulations and returns desired result set / exposes methods to do required operations.

Here is a Proof of concept code snippet which might be helpful to you to call web services using JQuery.Ajax  :

$.ajax({
// type: Type, //GET or POST or PUT or DELETE verb
url: Uri, // Location of the service
// data: Data, //Data sent to server
dataType: DataType, //Expected data format from server
cache: false, // no-cache
success: function (msg) {//On Successfull service call
ServiceSucceeded(msg);
},
error: ServiceFailed// When Service call fails
});
