Every programmer or web developers know about what is java scripts and what their benefits and you also know about javascript. But this article I would like to provide information about extended javascript and its benefits
ExtJs is a JavaScript library for building interactive web applications using techniques such as Ajax, DHTML and DOM scripting. Ext provides an easy-to-use, rich user interface, much like you would find in a desktop application. This lets the web developers concentrate on the functionality of web applications instead of the technical caveats.
ExtJs makes web application development simple by:Providing easy-to-use cross-browser compatible widgets such as windows, grids, panels, charts, toolbar and forms and many more widgets for rich look and fill. The widgets are already fine-tuned to handle the intricacies of each web browser on the market, without us needing to change a thing.Interacting with the user and browser via the Event Manager, responding to the users keystrokes, mouse clicks, and monitoring events in a browser such as a window resize, or font size changes.Communicating with the server in the background without the need to refresh the page. This allows you to request or post data to or from your web server using AJAX and process the feedback in real time.Ext JS comes with full sweets of with the Layout management tools to give you full control to organize and manipulate the UI as requirements dictate.When we use Ext widgets, the browser compatibility is taken care of by the Ext library, so that each widget looks exactly the same in most of the popular browsers.The Term AJAX (Asynchronous JavaScript and XML) is an overly-complicated acronym for saying that processes can take place in the background while the user is performing other tasks. A user could be filling out a form while a grid of data is loadingboth can happen at the same time, with no waiting around for the page to reload.Ext JS really shines in making web applications easy to-use and intuitive. If you are a web application developer, it's a great library to have in your arsenal. And many .Net developers often used Ext JS for developing creative web applications http://www.articlesbase.com/programming-articles/useful-information-about-extended-java-script-4342674.html
