Javascript 使用datetime输入控件全球化验证问题

我试图使用cldr数据和全球化功能来验证我在ASP.NET核心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。我的操作系统设置为en US，浏览器有三种显示为“de”的语言，并且是

navigator.languages

列表的第一种语言）

虽然逗号分隔符被正确识别（它接受日期输入的

、

和拒绝

），但我无法理解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

创建表单还显示格式正确的输入字段

将

用作逗号分隔符会引发无效的错误

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，我找到的唯一临时解决方案是替换jquery.validate.globalize.js中的validator.methods.date函数

$.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);
};

$.validator.methods.date=函数（值，元素）{
var fecha=新日期（值）；
var dia=fecha.getDate（）+1；
var mes=fecha.getMonth（）+1；
var anio=fecha.getFullYear（）；
如果（直径<10）{
直径='0'+直径；
};
如果（mes<10）{
mes='0'+mes；
};
var newValue=dia+'/'+mes+'/'+anio；
var val=Globalize.parseDate（newValue，$.validator.methods.dateGlobalizeOptions.dateParseFormat）；
返回此。可选（元素）| |（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。

你有没有找到更好的解决方案？（覆盖验证器方法）。@rufo遗憾的是没有。我认为在最后进行模式检查并在提交时执行转换将是一种方法。
