                var id = $(this).val();
                var dataString = 'cid='+id;
                //alert(dataString);
                $.ajax({
                    url: 'dataAjax.php',
                    type: 'post',
                    data: dataString,
                    success: function(response) {

                      // Parse the jSON that is returned
                        var Vals    =   JSON.stringify(response);
                        // These are the inputs that will populate
                        $("input[name='add']").val(Vals.add);
                        $("input[name='mobile']").val(Vals.mobile);
                        $("input[name='email']").val(Vals.email);
                         }
            });
        });
    });
</script>

Ini adalah Kode File PHP lainnya:-

<?php
// This is where you would do any database call
if(!empty($_POST)) {
    // Send back a jSON array via echo
    echo json_encode(array("add"=>'India',"mobile"=>'1234567890','email'=>'[email protected]'));

}
?>
