如何使用kendo验证器验证日期格式为yyyy-MM-dd？ [英] How to validate a date is in the format yyyy-MM-dd using kendo validator?

问题描述

我有一个kendo日期选择器，其构造如下：

I have a kendo date picker that is constructed as follows:

$("#date").kendoDatePicker({
    format: "yyyy-MM-dd",
    footer: " ",
    parseFormats: ["MM/dd/yyyy", "dd/MM/yyyy"]
  });

我想使用kendo验证器来验证日期是否包含有效日期，格式为yyyy-MM-dd。我已经尝试过：

I would like to use the kendo validator to validate that the date contains a valid date in the format of yyyy-MM-dd. I have tried this:

<input type="date" id="date" placeholder="yyyy-mm-dd" name="date" required data-required-msg="Please enter a date." data-date-msg="Please enter a valid date."/>

验证器正确验证必需条件时，似乎没有验证日期是正确的格式或是有效的日期。例如，abc作为有效日期通行为2013-18-85。如何使用验证器确保正确格式的有效日期？

While the validator does correctly validate the "required" condition, it does not seem to validate that the date is in the correct format or is a valid date. For instance, "abc" passes as a valid date as does 2013-18-85. How can I use the validator to ensure a valid date in the correct format?

推荐答案

如果您想要验证 a date 您需要定义规则（无内置规则）。

If you want to validate a date you need to define a rule (no built-in rule).

尝试定义：

$("#date").kendoValidator({
    rules: {
        date: function (input) {
            var d = kendo.parseDate(input.val(), "yyyy-MM-dd");
            return d instanceof Date;
        }
    }
});

注意：记住，KendoUI首先使用 parseFormats 选项来解析日期，然后将其转换为格式选项，最后运行验证。这就是为什么我使用验证 yyyy-MM-dd 而不是 [MM / dd / yyyy，dd / MM / yyyy] 。

NOTE: Remember that KendoUI first uses parseFormats option for parsing the date, then converts it to the format option and finally run validations. That's why I use in validation yyyy-MM-dd and not ["MM/dd/yyyy", "dd/MM/yyyy"].
