                    Prior to HTML 5 it was difficult to write code for playing video. Developer used to write code based on browser types and OS. In HTML 5 new tag has been introduced to support videos. Its very straight forward to use not much of coding involved in using it. <video id="myVideo" poster="start.jpg" autoplay="autoplay" width="100px" height="150px"     audio="muted" loop="loop" controls="controls" src="video.mp4" preload="auto"> </video> Attribute                                   Description autoplay=autoplay                     If present, then the video will start playing as soon as it is ready poster=url    ...

Many of the web application face major challenge for performance. There are various ways to improve performance of the website. It can be Server Side Code Improvement (e.g. code analysis and refactoring, db side changes etc), Hardware Side (improve on hardware configuration, increasing number of servers etc) and Client Side. When  i say client side here i mean User Interface (such as Image, JS, css etc). I am going to explain in this article about various opportunities for performance improvements from Client side. This is not very exhaustive list but some of the items which can be controlled and taken care easily. o Avoid complete page refresh wherever possible. You can use AJAX calls. This way we can reduce amount of the network data to be transferred and complete page refresh. o Use "GET" for AJAX request where ever possible if data being transferred is not sensitive, amount of data is less, or you are getting data from server. Reason behind this is POST request creates t...

 Dojo is an open source framework which provides various inbuilt functions for AJAX, Widgets, Events, and Effects etc. These functions make life easier for the developer. They provide complete abstraction from the complexity involved behind the scene. I am going to cover AJAX feature provided by Dojo in this article. Normally when we code for AJAX we think of creating request, forming the data which needs to be sent to server, error handling, timeout scenarios, response handling etc. We can’t escape from any of these points when we write coding and due to this code becomes complex and cumbersome to understand and maintain. Dojo provides cleaner and easier approach to create a code for handling AJAX calls. Dojo Basics: Two types of request are sent to server for any AJAX request, Post and Get. Dojo provides two function for these two types dojo.xhrGet and dojo.xhrPost methods. These two functions have all the AJAX capabilities in built. It takes care of creating request, forming the...
