  • • Most Web crawlers do not execute JavaScript code,^[15] so in order to be indexed by search engines, a Web application must provide an alternative means of accessing the content that would normally be retrieved with Ajax. It has been suggested that a headless browser may be used to index content provided by Ajax-enabled websites.^[16]
     
    • Any user whose browser does not support JavaScript or XMLHttpRequest, or simply has this functionality disabled, will not be able to properly use pages which depend on Ajax. Devices such as smartphones and PDAs may not have support for the required technologies, though this is becoming less of a problem. The only way to let the user carry out functionality is to fall back to non-JavaScript methods. This can be achieved by making sure links and forms can be resolved properly and not relying solely on Ajax.^[17]
     
    • Similarly, some Web applications that use Ajax are built in a way that cannot be read by screen-reading technologies, such as JAWS. The WAI-ARIA standards provide a way to provide hints in such a case.^[18]
     
    • Screen readers that are able to use Ajax may still not be able to properly read the dynamically generated content.^[19]
     
    • The same origin policy prevents some Ajax techniques from being used across domains,^[8] although the W3C has a draft of the XMLHttpRequest object that would enable this functionality.^[20] Methods exist to sidestep this security feature by using a special Cross Domain Communications channel embedded as an iframe within a page,^[21] or by the use of JSONP.
     
    • The asynchronous callback-style of programming required can lead to complex code that is hard to maintain, to debug^[22] and to test.^[23]

The DOM is accessed with JavaScript to dynamically display, and allow the user to interact with, the information presented. JavaScript and the XMLHttpRequest object provide a method for exchanging data asynchronously between browser and server to avoid full page reloads.

With Ajax, web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page.
  • Data is retrieved using the XMLHttpRequest object or through the use of Remote Scripting in browsers that do not support it. Despite the name, the use of JavaScript and XML is not actually required, nor do the requests need to be asynchronous.^[3]
  • alternative techniques for the asynchronous loading of content date back to the mid 1990s. Java applets were introduced in the first version of the Java language in 1995. These allow compiled client-side code to load data asynchronously from the web server after a web page is loaded.^[5] In 1996, Internet Explorer introduced the IFrame element to HTML, which also enables this to be achieved.^[6]

  • creating interactive web applications.
  • the entire web page does not have to be reloaded each time the user performs an action.
  • extra data is requested from the server and loaded in the background without interfering with the display and behavior of the existing page.
  • Web pages, unlike native applications, are loosely coupled, meaning that the data they display are not tightly bound to data sources and must be first marshaled (set out in proper order) into an HTML page format before they can be presented to a user agent on the client machine. For this reason, web pages have to be re-loaded each time a user needs to view different datasets. By using the XMLHttpRequest object to request and return data without a re-load, a programmer bypasses this requirement and makes the loosely coupled web page behave much like a tightly coupled application, but with a more variable lag time for the data to pass through a longer "wire" to the remote web browser.
  • For example, in a classic desktop application, a programmer has the choice of populating a tree view control with all the data needed when the form initially loads, or with just the top-most level of data—which would load more quickly, especially when the dataset is very large. In the second case, the application would fetch additional data into the tree control depending on which item the user selects. This functionality is difficult to achieve in a web page without Ajax. To update the tree based on a user's selection would require the entire page to re-load, leading to a very jerky, non-intuitive feel for the web user who is browsing the data in the tree.
