FreeMarker和JS Alt + z快捷方式

Question

我的问题似乎很简单，但确实令人困惑。我有HTML的测试输入，但是有FreeMarker。每次从键盘输入符号时，JS脚本都会运行，以指定是按键事件还是字母。问题是，如果您想通过按Alt + z输入特定字母，它会按Ctrl + z的形式工作，然后将其放入。

脚本：

                function validateInputValue(event, id, regexpValue) {
                var regexp = new RegExp(regexpValue);
                var key = event.keyCode || event.which;
                //var fieldValue = jQuery("#" + id).val();

                // Allow: backspace, delete, tab, enter, arrow keys
                var controlKeys = [8, 46, 9, 13, 37, 38, 39, 40];
                // Ctrl+ anything or one of the conttrolKeys is valid
                var isControlKey = event.ctrlKey || controlKeys.join(",").match(new RegExp(key));

                if (isControlKey && !event.altKey) {
                    return;
                }

                if (!regexp.test(String.fromCharCode(key))) {
                    event.preventDefault();
                }
            }

我已经在if语句中添加了“！event.altKey”，以使用alt键阻止所有事件，但是现在当按下Alt + z时，它不会运行。调试器不会在断点处停止，但它仍可作为“撤消”命令使用。它可以与其他特殊字母（例如Alt + s）配合使用。有什么办法可以使其正常工作？
