| Ajax-an Introduction: Disadvantages of Ajax |
|
- Though Ajax is a cross platform tool, yet it has also a limitation, as it cannot run in the older version of Opera and Safari browser and needs to enable XMLHttpRequest to run Ajax. The
implementation criteria also differ marginally in all sorts of browsers.
- Ajax generates dynamic pages that do not register itself with cookies, so user can’t found
previous pages by pressing ‘Back’ button, but can enable with GET HTTP requests. User
also feels to bookmark the earlier pages after updating it and for avoiding this problem;
programmer must feed URL fragment identifier. Cookies also don’t work with large request
and hence need to add the cookie request.
- The IFrame requests in Ajax barred synchronous request and for it, server pages must be
designed to work with IFrame request but the implementation process varies in several
browser. It can leave extra request in history as per depends up on the browser.
- While making programme, user must consider network latency carefully that can be proved
panic for the user with an unusual delay in processing if it is not written properly with
correct handling XMLHttp request.
- In the absence of proper sitemap, it was difficult for the Search Engine Optimizer to search
the web page as search engine too feel difficulty to execute it, while if it is provided data
with full-page refresh.
- As per the latest report, some researchers have found that a large number of power users
are not pleased with the performance of Rich Internet Application that was based on Ajax
in terms of local rendering of complex business. The rendering process was taking uneven
delay.
