It seems that you are using Codeigniter Framework. And Hence I have a doubt with your Ajax URL Path.

You have given

 url: "<?php echo base_url() ?>"+"Index.php/Login_cntrl/loginn",

But In codeigniter it should be like

 url: "<?php echo base_url() ?>"+"/Login_cntrl/loginn",

OR

 url: "<?php echo base_url('Login_cntrl/loginn') ?>",

It can also possible that you are calling this ajax from a script file. Which is not a php file. so the base_url() function will not work there. In that case you have to save base_url into a input variable in a hidden format. and then should be fetch in your ajax code.

<input type="hidden" name="myurl" value="<?php echo base_url();">

and then ajax one

var myurl = $("#myurl").val();
