But nothing, any idea?

telephone_number is the id of the input.

Answer 1

use this

var $a = jQuery('#telephone_number').val();

OR

var $a = $('#telephone_number').val();

Answer 2

   var $a = $('#telephone_number').val();

    alert($a);

currently you are not passing the div id to jQuery, u are just doing (#tel_no) this is wrong.
