<head>
<meta charset="utf-8">

<script language="javascript" type="text/javascript">
    window.onload = function () {
        btnSubmit.addEventListener("click", displayResult);
        function displayResult() {
            if (txtNumbers.value != "") {
                var numbers = txtNumbers.value.split(",");
                var outputResult = "Multiply each value with 9:\n";
                for (var i = 0; i < numbers.length; ++i) {
                    numbers[i] *= 9;
                }
                outputResult += "[" + numbers.join(",") + "]\n";
                outputResult += "Subtract 20 from each value:\n";
                for (var i = 0; i < numbers.length; ++i) {
                    numbers[i] -= 20;
                }
                outputResult += "[" + numbers.join(",") + "]\n";
                outputResult += "Multiply each value with 7:\n";
                for (var i = 0; i < numbers.length; ++i) {
                    numbers[i] *= 7;
                }
                outputResult += "[" + numbers.join(",") + "]\n";


                txtResult.value = outputResult;
            } else {
                alert("Enter numbers!!!")
            }
        };
    }
