AJAX Issues


Hello folks! welcome back to a new section of our tutorial on AJAX. In this tutorial post, we are going to be discussing about some of the issues facing AJAX.

AJAX is growing and expanding really fast and that is the reason that it contains a lot of issues with it. But we hope that as time goes by, they will be resolved and AJAX will become ideal for web applications. In this tutorial, we are going to be listing down some of the issues that AJAX is currently facing.

JavaScript code is visible to a hacker

  • Poorly designed JavaScript code can bring about security problems.

No support of XMLHttpRequest in older web browsers

  • Iframe will help.

JavaScript technology dependency and incompatibility

  • Must be enabled for applications to work.
  • Still some browser incompatibilities exist.

AJAX-based applications 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 guidelines yet.

No standardization of the XMLHttpRequest yet

  • Future versions of Internet Explorer will address this issue.

Complexity is increased

  • Server-side developers will need to understand that presentation logic will be required in the HTML client pages as well as in the server-side logic.
  • Page developers must have JavaScript technology skills.

Toolkits/Frameworks are not matured yet

  • Most of them are in beta phase.
