date( )

Makes the element require a date.

Return true, if the value is a valid date. Uses JavaScripts built-in Date to test if the date is valid, and does therefore no sanity checks. Only the format must be valid, not the actual date, eg 30/30/2008 is a valid date. Works with text inputs!

Examples:

Demo
View Source

Makes "field" required and a date.

$("#myform").validate({
  rules: {
    field: {
      required: true,
      date: true
    }
  }
});
