Stopping the Ajax Process

An Ajax based application added in a website will certainly improve the user’s experience. Because of the programming technique’s interactivity, developers will be able to provide more than just a simple “click” on some data. Users will be able to see the changes of their data in real time without even changing some parts of the webpage.

Through Ajax, a virtual online application could be easily achieved. This programming language does not even require any download at all for the users which adds to the appeal as well as accessibility of the created application.

However, the usual Ajax based application will require a relatively powerful gadget for faster access. Although the Ajax based application is geared for all users (even those with weak internet connectivity), the best experience on Ajax will only happen in better conditions which is on a better gadget as well as a good internet connection.

In relatively weaker conditions, an Ajax based application might not work as expected and would even cause delay and inconvenience for the user. It is important for developers to consider this situation in order to maintain accessibility of their application. Although Ajax should be the focus for developers, accessibility is still the main feature developers should consider.

When the gadget or connection is too weak to handle a function, developers should step in and implement a code that would automatically “abort” the said function. This form of function practically stops the Ajax based application and proceeds with another function almost similar to the aborted process to provide the same result.

This technique is actually a smart solution for developers who wanted to improve their application significantly and prevent exclusion of other users. If it is properly created, it will definitely increase accessibility and sustain user experience.

Stopping the Ajax function starts by locating the object that trigger functions in the application. The most common case of accessibility problems is on being asynchronous which comes from the XHR (XMLHttpRequest). When this function is be controlled and stopped, the asynchronous function will stop as well.

Stopping the function is not necessarily to abort the function without options. Basically, when the object that comes with XHR is implemented, developers could create an “if” function which will create an option for the browser to implement another function.

This part is a little bit tricky since developers would tend to stick to XHR functions before creating an “if” for the browser to read. Developers have to choose between convenience of an Ajax based function which is asynchronous through XHR and accessibility by stopping the function.

Developers have to choose since aborting functions in Ajax will mean the asynchronous interaction will stop. The alternative function will have to be followed up with a series of functions that will complement the new function. This could be an entirely new function which will require more time for developers.

Aborting Ajax is a very simple process to implement but the consequences would be a lot if the stopped function will not be followed up to maintain the accessibility.
