            let vertical_pattern = /\v/;
            var input_val1 = 'javatoint website\v';
            var input_val2 = '!!#HiiErr';
            var input_val3 = '\v%!@!#$%0';
            var replace_input = '7777';
            var vertical_t1 = input_val1.replace(vertical_pattern, replace_input);
            var vertical_t2 = input_val2.replace(vertical_pattern, replace_input);
            var vertical_t3 = input_val3.replace(vertical_pattern, replace_input);
        // Get the output of the replace value of the vertical tab characters
        var ele = document.getElementById("regex_information");
        ele.innerHTML = "javatoint website\v : " + vertical_t1 + "<br> !!#HiiErr : " + vertical_t2 +
            " <br> \v%!@!#$% : " + vertical_t3;
        }
    </script>
