    Seems that you don't send your data properly. Try this:

    $.ajax({
    type: "POST",
    url: "example/name",
    data: {send: send},
    success: function(value) {

    }
});

    In this case you will be available as $_POST['send'].

    First you can define a global variable that can be used as your base url in the jquery code. Place this in the <script> tag of the page <head> section

             //<![CDATA[
              base_url = '<?php echo base_url();?>';
        //]]>

    Than do the ajax request like this 

            var data  = 'var1=aaa&var2=bbb';

        $.ajax({
            type: "POST",
            url: base_url+"mainController/getData/", //base_url is the variable which you have defined in the head section 
            data: data,
            success: function(response){
                   alert(response);
            }
        });

    Than in the controller retrieve the post data like this 

           class MainController extends CI_Controller {

            function getData()
            {
               $var1 = $this->input->post('var1');
               $var2 = $this->input->post('var2');

               echo $var1;
               echo '<br/>';
               echo $var2;
            }  
       }

    You should specify the value to be posted with the send i.e. it should be like-

    $.ajax({
    type: "POST",
    url: "example/name",
    data: 'send='+1,
    success: function(value) {

    }
});

    Then you will have the value of this variable as you are doing.

    using-

    $this->input->post('send');

    Try this one , this is ajax call

     $.post('<?php echo base_url()?>example/name',{send:send}, 
          function(data) {

      });

    then access it using post into your controller like this

    class Example extends CI_Controller {
function name() {
    $_POST['send'];
  }
}
