Validate date and datetime with Bootstrap datetime picker, Jquery validation plugin in an Asp.Net MVC4 application

Question

I am currently developping a MVC Asp.Net 4.6 WebApp with Bootstrap 3.1.1, Eonasdan datetime picker v4.7.14 and jquery validation plugin v1.14.0.

And I've got some problem validating the date.

• My Model looks like that:

  public class PersonModel{
      ...
  
      [Required]
      [Display(Name = "Date of Birth")]
      public DateTime? DateOfBirth { get; set; }
  
      ...        
  }
  

• My View looks like that:

  <div class="form-group">
      @Html.LabelFor(x => x.DateOfBirth):
      <span class="text-danger"><b>*</b></span>
      <div class="input-group datepicker">
          <span class="input-group-addon">
              <span class="glyphicon glyphicon-calendar"></span>
          </span>
          @Html.TextBoxFor(x => x.DateOfBirth, new {@class = "form-control", @data_date_format = "DD/MM/YYYY", @placeholder = "DD/MM/YYYY"})
      </div>
      @Html.ValidationMessageFor(x => x.DateOfBirth, "", new { @class = "text-danger" })
  </div>
  

• The associated Js code to init th datetime picker:

  (function () {
      // Init bootstrap date/time pickers
      $(".datepicker").datetimepicker({
          useCurrent: false
      });
  })(jQuery);
  

  Using jQuery.validator, even if the the date looks good, I always get this error:

  

  I know that jQuery.validator works fine with the jquery.ui.datepicker but how can I make it work with the bootstrap.datetimepicker ?

You can overrides the date method of the Jquery.validator plugin :

(function () {
    // overrides the jquery date validator method
    jQuery.validator.methods.date = function (value, element) {
        // All dates are valid....
        return true;
    };
})(jQuery);

Because the bootstrap datetime picker use moment.js, you can check if the date is valid like that:

(function () {
    // overrides the jquery date validator method
    jQuery.validator.methods.date = function (value, element) {
        // We want to validate date and datetime
        var formats = ["DD/MM/YYYY", "DD/MM/YYYY HH:mm"];
        // Validate the date and return
        return moment(value, formats, true).isValid();
    };
})(jQuery, moment);
