Description: OnLoad is one of the most powerful functions in an Ajax based application. With this function developers could easily render other functions which enables asynchronous streaming of data. OnLoad also have the ability to target specific areas in the webpage so that each window will be working independently which further enhances the interactivity of an Ajax based website. What makes OnLoad even more powerful is the ability of the function to interact not only with the server but also with the user as well. Developers could point different functions if OnLoad is optimized in the website.
