AJAX-Design
There are two ways in developing Ajax in terms of coding principles. Developers could either use the tradition DOM as they would work with JavaScript or they could develop Ajax through OO (object oriented) coding which is usually favorable for developing Ajax.
The Case of DOM for Ajax
Developing Ajax is possible with the use of DOM. There are online applications today that used DOM for their applications development. Although it’s possible, developing Ajax through DOM is very difficult for inexperienced developers. Ajax is a difficult web technique to figure out because it needs integration with XML, HTML and even other web languages depending on the need of the website. If you bring these functions together in DOM, they will be placed in a procedural manner so that each function will eventually complement each other and build a highly effective application.
This setting however, is only applicable when all functionalities have been coded correctly. If one line is not coded correctly or not compatible with another function, the whole process would eventually cease to work. Developers have to inspect the entire coding when this happens. DOM doesn’t provide developers a clear idea where the error happened.
OO (Object Oriented in Ajax)
Object oriented programming, on the other hand, will work well in developing Ajax applications. The key to the appeal of OO to various developers is its familiarity in development. DOM requires developers to build an application in the procedural manner however OO don’t require that scheme. What it requires instead is to build the functions as different objects which will eventually interact with each other. Each function will be treated independently so that error tracking will be easier and eventually faster.
Modification of functions in OO is even easier compared to DOM. As we have previously indicated, developing Ajax through DOM is difficult because they clustered as one instead of independent functions. That means a single additional function would mean revising the whole script so that the new function would be compatible to original function and vice versa.
OO on the other hand is open to different changes and implementation of these changes is very easy. They could inject the function to one of the objects and reconfigure that particular object only. The function would eventually connect to the server faster and implement the changes easier.
There are libraries that could be used in developing Ajax through OO. Developers who are not familiar with JavaScript could use these scripts to build Ajax faster.
Help for DOM
Insisting on DOM is ok for Ajax as long as you know how to do it properly. However, there are ways on how to improve coding of DOM significantly. Instead of writing codes, frameworks could be used in developing applications through DOM.
Most of the Ajax frameworks follow DOM coding and some of these frameworks require little to no JavaScript coding from the developer. Although customization is a lot harder for frameworks, development is a little bit easier with the help of frameworks.
