Hellow ,
some basics things about the Ajax. I think Ajax is cool and it’s a
buzzword in today’s computing world.
The abbrivation of Ajax is Asynchronous JavaScript and XML.
Ajax is Used by many popular internet companies for many reasons . In
normal client server environment what happens the client make a http
request to the webserver and the webserver response according to
the requirement.
Now lets see hoe Ajax works:
The client makes a http request for specific information and the server
returns the specific requsted information(not the whole page)
Here are the advantages of Ajax :
In Ajax the small request will be send (only required i.e perticular part)
so the response time will be less each time the whole page is not
required to retrive so network traffic wiil be decreased . In ajax when u
r submit the page the page is not flickering , give the nore responsive
feel to user.
Ajax behave like desktop appication
In ajax only the perticular part of the page needs to updated,so the
response action is faster
Following are the drawbages of Ajax :
One of the most common poblem is to integrated with browser if the
use click on back button might not allowed them to get the information
that they want.
Another disadvantages is that in ajax perticulat part is updated so
sometimes it might create synchronization problem with existing part
otheres disadvantages are
Cross-browser incompatibilities
Accessibility issues
Extra programming
so these are the things …….
