$.ajax({
  type: “POST”,
  async:false,
  url: “test/aj”,
  data: dataString,
  success: function(text)
  {
}
the echo item is not returning to function(text)

use a full url, check in firebug/console to see that the ajax request is being sent to the correct url and also the post data.

i am new in codeigniter ,test is class and aj is function ,so i just pass the value to that functon and does not return any thing

Which means nothing to your ajax request, since it’s javascript and not CI.  Again, try using a FULL url (http://yoursite.com/test/aj) or whatever in the ajax request…

Use a javascript console in your browser to see the ajax request and check if it’s going to the right place.

console reply is “NetworkError: 404 Not Found - http://localhost/CodeIgniter_2.1.2/test/aj”

console reply is “NetworkError: 404 Not Found - http://localhost/CodeIgniter_2.1.2/test/aj”

Means your ajax request goes to the wrong address or your controller dont respond the way you like. Is the controller itself working proper?

controller is working properly but all paths is not working properly, any problem in routes,config

If this is your path “http://localhost/CodeIgniter_2.1.2/test/aj” ...

- There could be a problem with special chars in url
- There could be a problem with your .htaccess
- There could be a problem with your routes.php

Just some ideas

Problem solved ,any how still have confusion about paths..thnx buddy
