javascript - How to escape the backslash "\" character in jquery inputmask?

Question

I'm trying to escape the escape char (\) to allow a user to input its username of Active Directory (DOMAIN\username), but it wont include the character in the input field.

I've used \, \\, \\\ and \\\\ in the mask, and none works. Also tried with the function escapeRegex(), but have had no success.

How can this be achieved?

JS:

(function ($) {
    $.extend($.inputmask.defaults.aliases, {
        'ACTIVE-DIRECTORY': {
            mask: function(a) {
                return a.domain + '\\\\*{1,20}';
            },
            greedy: false,
            definitions: {
                '*': {
                    validator: '[A-Za-z\u0410-\u044F\u0401\u04510-9]',
                    cardinality: 1,
                    casing: 'lower'
                }
            }
        }
    });
})(jQuery);

This is what it shows in HTML:

您如何尝试使用编码字符编写指令路径？

(function ($) {
var dicrectory = encodeURIComponent(directory_path);
    $.extend($.inputmask.defaults.aliases, {
        dicrectory: {
            mask: function(a) {
                return a.domain + '\\\\*{1,20}';
            },
            greedy: false,
            definitions: {
                '*': {
                    validator: '[A-Za-z\u0410-\u044F\u0401\u04510-9]',
                    cardinality: 1,
                    casing: 'lower'
                }
            }
        }
    });
})(jQuery);
