ASP.NET MVC验证不适用于bootstrap模式

Question

I can't get the bootstrap modal and asp.net mvc validation start working together. I've got a complex form with some validation displayed in bootstrap modal. Unfortunetely when I hit the submit button the validation doesn't work at all.

The form uses standard asp.net mvc validation. Below there is a part of it just to get the idea of how it is build:

@using (Html.BuildForm().AddClass("form-horizontal").Id("contact-add-popup").EncType(FormEncType.MultipartData).Begin()) {
@Html.AntiForgeryToken()
@Html.Partial("_Alerts")
<div class="control-group">

<div class="control-group company-field">
    @Html.BuildLabelFor(m => m.Name).AddClass("control-label")
    <div class="controls">
        @Html.BuildTextBoxFor(m => m.Name).AddClass("input-xxlarge")
        @Html.ValidationMessageFor(m => m.Name)
    </div>
</div>
(...)

Here is my modal:

<div id="createContactModal" class="modal hide fade modal-contact" tabindex="-1" role="dialog" aria-labelledby="createContactModalLabel" aria-hidden="true" data-backdrop="static">
<div class="modal-header">
    <h4 class="modal-label" id="createContactModalLabel">Add contact</h4>
</div>
<div class="modal-body">
    @Html.Partial("_CreateContact", new ContactCreateModel())
</div>
<div class="modal-footer">
    <a href="javascript:$('#contact-add-popup').submit();" class="btn btn-primary">Zapisz</a>
    <button class="btn" data-dismiss="modal" aria-hidden="true">Zamknij</button>
</div>

And some javascript that I hope to get the validation working:

        $('#createContactModal').on('shown', function () {
            $("#contact-add-popup").removeData("validator");
            $("#contact-add-popup").removeData("unobtrusiveValidation");
            $.validator.unobtrusive.parse("#contact-add-popup");
        });

        $('#contact-add-popup').on('submit', function(e){
            e.preventDefault();

            $.validator.unobtrusive.parse($("#contact-add-popup"));

            if ($('#contact-add-popup').valid()){
                alert('AJAX');
            }
        }); 

The line if ($('#contact-add-popup').valid()) returns always true. How can I get the modal and validation to work?

Answer 1

You should try this way:

var form = $("#contact-add-popup")
        .removeData("validator")
        .removeData("unobtrusiveValidation");

$.validator.unobtrusive.parse(form);

Answer 2

After some research I found that javascript validation script files were missing - so the client side validation was not working at all. After including these files everything works fine.

Thanks for all answers.

Add this in the base view, load modal and enable client side validation.

@section scripts {

  @{ await Html.RenderPartialAsync("_ValidationScriptsPartial"); }

  @* The normal bootstrap behavior is to only grab the content
     for the modal once, if you need to pull in different partial
     views then the data on the modal will have to be cleared. *@

  <script src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.js"></script>

  <script type="text/javascript">
    $(function () {
      $('#modal-container').on('show.bs.modal', function (event) {
        var button = $(event.relatedTarget); // Button that triggered the modal
        var url = button.attr("href");
        var modal = $(this);
        //enable client side validation after page is loaded
        modal.find('.modal-content').load(url, function () {
          $('#registration_form').removeData("validator");
          $('#registration_form').removeData("unobtrusiveValidation");
          $.validator.unobtrusive.parse('#registration_form');
        });
      });
    });
  </script>
}
