我正在从一本书和一本代码示例中学习JavaScript,我从本书中编写它只适用于jsfiddle。我尝试过Chrome和IE,但提示不会出现。这是我的代码:

<script type="text/JavaScript">
            var userNumbers = new Array();
            var userInput = 0;
            var arrayIndex = 0;
            var message = '';
            var total = 0;

            while (userInput != 99) {
            userInput = prompt("Enter a number, or 99 to exit", "99");
            userNumbers[arrayIndex] = userInput;
            arrayIndex++; 
            }
            message += 'You entered the following:\n';
            for (var i = 0; i< arrayIndex-1;i++) {
                message += userNumbers[i] + '\n';
                total += Number(userNumbers[i]);
            }
            message += 'Total:' total + '\n';
            alert(message);
        </script>

你的专栏:

message += 'Total:' total + '\n';

应该是

message += 'Total:' + total + '\n';
