Question

我正在尝试使用cldr-data和全球化功能来验证我在ASP.NET Core MVC Web项目中的输入。

出现问题是因为它似乎可以基于navigator.language属性加载正确的cldr数据文件（我知道这并不总是准确的，但在这种情况下应该是有效的。我的OS设置为en-在美国，浏览器显示三种语言，其中显示“ de”，并且是navigator.languages）列表的首位

尽管可以正确识别逗号分隔符（它接受,并拒绝.作为日期输入，但我无法弄清楚为什么日期被标记为无效。

日期以正确的de dd.mm.yyyy格式显示

创建表单还会显示具有正确格式的输入字段

使用.作为逗号分隔符会导致无效

使用datetimepicker选择器会给我一个无效的日期

我在尝试设置西班牙文化时遇到了同样的问题，我发现的唯一临时解决方案是替换jquery.validate.globalize.js中的validator.methods.date

$.validator.methods.date = function (value, element) {
    var fecha = new Date(value);
    var dia = fecha.getDate() + 1;
    var mes = fecha.getMonth() + 1;
    var anio = fecha.getFullYear();
    if (dia < 10) {
        dia = '0' + dia;
    };
    if (mes < 10) {
        mes = '0' + mes;
    };
    var newValue = dia + '/' + mes + '/' + anio;
    var val = Globalize.parseDate(newValue, $.validator.methods.dateGlobalizeOptions.dateParseFormat);
    return this.optional(element) || (val instanceof Date);
};

也许这不是最好的解决方案，但这是我实现日期验证的唯一方法。
