AJAX - Current Issues

AJAX is growing very fast and that is the reason that it contains many issues with it. We hope with the passes of time, they will be resolved and AJAX will become ideal for web apppcations. We are psting down a few issues that AJAX currently suffers from.

Complexity is increased

Server-side developers will need to understand that presentation logic will be required in the HTML cpent pages as well as in the server-side logic.

Page developers must have JavaScript technology skills.

AJAX-based apppcations can be difficult to debug, test, and maintain

JavaScript is hard to test - automatic testing is hard.

Weak modularity in JavaScript.

Lack of design patterns or best practice guidepnes yet.

Toolkits/Frameworks are not mature yet

Most of them are in beta phase.

No standardization of the XMLHttpRequest yet

Future version of IE will address this.

No support of XMLHttpRequest in old browsers

Iframe will help.

JavaScript technology dependency and incompatibipty

Must be enabled for apppcations to function.

Still some browser incompatibipties exist.

JavaScript code is visible to a hacker

Poorly designed JavaScript code can invite security problems.
