DOM is one of the unique functions that made JavaScript what it is today: a great RIA language, becoming the core of Ajax. Understanding Ajax is virtually impossible when you do not have faint information about DOM. DOM which stands for Document Object Model, makes it possible for JavaScript to read HTML and transmit them to a webpage just like a JavaScript should be. With the use of DOM, developers should find it easy to create HTML files and get JavaScript to load them as an RIA.

More and more Ajax developers are choosing JSON for their data transfer instead of XML. Although XML has been the pillar of Ajax (X is for XML), JSON has become the choice of most developers because it was particularly built for JavaScript. Compared to XML, JSON is lighter and will work faster compared to XML. This lightweight function enables Ajax based websites and applications to run faster. The reason why JSON is very efficient in data transmission is its ability to function

Communication from the server to the client sometimes is broken up that absolutely nothing is loaded to the webpage. It is a very easy concept most of the time since you will just load your XMLHttpRequest properly. However, the problem usually occurs when as simple as XML and HTTP cannot even recognize the request from XMLHttpRequest. One of the tricks to ensure the program will properly load is to wrap the whole function in an AJAX loader. There are a lot of codes and samples out

Apart from being used in complicated RIAs with colorful interfaces, Ajax is also used for a more practical use such as data control and interaction. There are functions that any developer could use to display data in an Ajax way which does not only look good but has efficient functions which could not be seen in HTML based sites. It is relatively easy to build a repeater control. A repeater control is a binding of XML, JavaScript and HTML codes that could get really messy

One of the biggest challenges of any developer is to enable the webpage to all visitors as fast as possible. Unfortunately, our knowledge always precedes our available technology. Although we can create very interactive websites with the ability to watch videos while having to look for information on the webpage itself, it requires advanced technologies that every one cannot afford. Until today, there are still people who rely on dial-up so that they can access the net. Most of today

Cross Site Script or XSS is one of the popular methods for attacking not only to Ajax based websites but almost any other website that accepts user inputs. Even before Ajax was conceptualized, this attack was already practiced by different hackers. There was one hack that was used in 2005 wherein MySpace.com was targeted. It uses a simple JavaScript function that could be embedded in user’s website and others. Once they view the webpage, the “My Hero” link is changed to the

Thanks to open-source, One can have practically everything for free in a computer. Although some advises against this because of possible viruses and spywares, you just have to look for a trusted source while sticking to your firewalls and anti-viruses to ensure you have a good program. In my opinion, open-source (free) frameworks are one of the best ways to revolutionize web and applications development. Think about it: there are thousands or even millions of developers in the world

If you are starting out in your first Ajax based program, one of the biggest challenges that you have to face is to let your users remember not to hit the back button. Most of the time, Ajax based programs does not like the back button. Unfortunately, Ajax does not have that functionality in bookmarking the previous page so that it could be reloaded anytime. With this development or some call it a disability; it is quite clear that today’s browsers were built without thinking

One of the best thing about the hype created by AJAX was the reaction of other developers. Of course, there are individuals they are willing to build an alternative for every hype which is usually considered as a rip-off of the original hyped programming. Such programs frequently fail even before it gets started. For example, just look at different web-based office applications since zoho.com made a mark. Though lots of alternatives are available, almost none came even close. But when you tra

When we talk about Ajax, we often encounter XMLHttpRequest, Flash, Java, iframe and frame functions. Without them, Ajax will practically be nothing. They provide the function and process data. But there is actually a trick on how to build an Ajax based program without using these functions. You don’t even need to fool the system and the trick is relatively simple. Unfortunately, there are no libraries or Ajax based frameworks that provide these functions so you may have to build it your
