How to validate a date is in the format yyyy-MM-dd using kendo validator?

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]

  });

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./>

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?

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

Try defining:

$(#date).kendoValidator({

    rules: {

        date: function (input) {

            var d = kendo.parseDate(input.val(), yyyy-MM-dd);

            return d instanceof Date;

        }

    }

});

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].
