ajax request to codeigniter controller from javascript

Question

I am making an ajax request from my codeigniter view in javascript function but nothing happens and the success alert (ok) pops up

function show_drop_downn(){
    document.getElementById("drop_downn").style.visibility = "visible"; 
    $.ajax({
        type: "POST",
        url: "http://localhost/ok/index.php/search/ajax_delete_ntify",
        success: alert('ok'),
    }); 
}

This is my controller it is working perfect, when i copy paste the url (used in ajax request) in my browser every thing goes good, controller makes a call to the model and it works perfect

function ajax_delete_ntify()
{
    echo "incontroller";
    $email=$this->session->userdata('email_of_user');
    $this->load->model('search_peoplee');
    $data['userid']= $this->search_peoplee->get_userid_from_email($email);
    foreach ($data['userid'] as $row)
    {
        $one=$row->userid;
    }
    $this->search_peoplee->delete_notifications($one);
    return;
}

What do you expect to happen? Also, check your consoles Network tab and verify the request is going thru. — tymeJV

You need to pass success a function. In your case you are running alert('ok') and passing success the return value of alert (which is undefined). You need to do success: function(){ alert('ok'); } — gen_Eric

What do you expect to happen after your AJAX call? Just running an AJAX call isn't going to display the contents of the URL on your page. You need to do that yourself. — gen_Eric

ajax gives a call to controller and that controller gives a call to model which is programmed to delete a row from a table in database but that never happens, i have made it sure that my controller and model work perfectly — user2969426

View :

function show_drop_downn(){
    document.getElementById("drop_downn").style.visibility = "visible"; 
    $.ajax({
        type: "POST",
        url: "http://localhost/ok/index.php/search/ajax_delete_ntify",
        success:function(
         console.log("success");
        )
    }); 
}

Controller :

function ajax_delete_ntify()
{
    echo "incontroller";
    $email=$this->session->userdata('email_of_user');
    $this->load->model('search_peoplee');
    $data= $this->search_peoplee->get_userid_from_email($email);
    $res=$this->search_peoplee->delete_notifications($data[0]->userid);
    if($res){
      echo json_encode(array('success'=>true));
    }else{
      echo json_encode(array('success'=>false));
    }
}
