jQuery validation: how to output error message to jQuery UI modal dialog

How can I change the error message of jQuery validation so when it validates the error is composed as bullet points inside a jQuery Ui modal dialog.

Tried this but it doesn't work as expected (i.e. the modal dialog only apperas once, but after it is closed, I can't bring the modal dialog back when submitting invalid data for second time).

Any tips will be appreciated. Thank you.

        $("#myform").validate({
          debug: true,
          errorPlacement: function(error, element) {
            error.prependTo('#dialog-message');
          },
          errorLabelContainer: $("dialog-message ul"),
          onblur: false,
          onkeyup: false,
          onsubmit: true,
          wrapper: "li",
          showErrors: function() {
            //$("#dialog").dialog("destroy");
            $("#dialog-message").dialog(开发者_JAVA技巧{
              modal: true,
              buttons: {
                Ok: function() {
                  $(this).dialog('close');
                }
              }
            });
            this.defaultShowErrors();
          }
        });
...

      <div id="dialog-message" title="Download complete">
        <p>test</p>
      </div>

Change this line:

$("#dialog-message").dialog({

To this:

$("#dialog-message").dialag('destroy').dialog({

This will destroy/re-create the widget correctly, or alternatively...

Run this on document.ready:

$(function() {
  $("#dialog-message").dialog({
     modal: true,
     autoOpen: false,
     buttons: { Ok: function() {
         $(this).dialog('close');
       }
     }
  });
});

And call just this in your validation, this way you're just opening the same dialog widget again:

      showErrors: function() {
        $("#dialog-message").dialog('open');
        this.defaultShowErrors();
      }

To use an on-submit validation only, add this options to your js code:

jQuery("#myForm").validate({
            ...
            onfocusout: false,
            onkeyup: false,
            onclick: false,
            ....
