javascript - jQuery 只允许拉丁字符

Question

我想要一个js代码，只允许输入带有数字和特殊字符的拉丁语宪章(Alt键盘序列，EX:!@#$%^&*()_|}{~!"?>:<?/][\=-'`，...)，我尝试了这样的操作，但它不适用于拉丁语数字和不可见字符键盘。我该怎么办？

        $(".latin_letters").on("keypress", function(event) {
            var englishAlphabetAndWhiteSpace = /[A-Za-z ]/g;
            var key = String.fromCharCode(event.which);
            if (event.keyCode == 8 || event.keyCode == 37 || event.keyCode == 39 || englishAlphabetAndWhiteSpace.test(key)) {
                return true;
            }
            return false;
        });
        $('.latin_letters').on("paste", function(e) {
            e.preventDefault();
        });

请尝试这个:

仅添加:- var englishAlphabetAndWhiteSpace = "/^[-@./#&+\w\s]*$/";

$(".latin_letters").on("keypress", function(event) {
        var englishAlphabetAndWhiteSpace = /^[-@./#&+\w\s]*$/;
            var key = String.fromCharCode(event.which);
            if (event.keyCode == 8 || event.keyCode == 37 || event.keyCode == 39 || englishAlphabetAndWhiteSpace.test(key)) {
                return true;
            }
            return false;
        });
        $('.latin_letters').on("paste", function(e) {
            e.preventDefault();
        });
