How to correctly validate a modal form

Question

I can't seem to get validation to work on my bootstrap modal, I have struggled with several of the examples that I have encountered.

What is the correct way to validate a bootstrap modal?

My HTML:

 <div class="modal fade" id="addMyModal" role="dialog">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h4 class="modal-title">Add Stuff</h4>
            </div>
            <div class="modal-body">
                <form class="form-control" role="form" id="newModalForm">
                    <div class="form-group">
                        <label class="control-label col-md-3" for="email">A p Name:</label>
                        <div class="col-md-9">
                            <input type="text" class="form-control required error" id="pName" name="pName" placeholder="Enter a p name" />
                        </div>
                    </div>
                    <div class="form-group">
                        <label class="control-label col-md-3" for="email">Action:</label>
                        <div class="col-md-9">
                            <input type="text" class="form-control" id="action" placeholder="Enter and action">
                        </div>
                    </div>
                </form>
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-success" id="btnSaveIt">Save</button>
                <button type="button" class="btn btn-default" id="btnCloseIt" data-dismiss="modal">Close</button>
            </div>
        </div>
    </div>
</div>

My Javascript:

$(function () {        

    $("#newModalForm").validate({
        rules: {
            pName: {
                required: true,
                minlength: 8
            },
            action: "required"
        },
        messages: {
            pName: {
                required: "Please enter some data",
                minlength: "Your data must be at least 8 characters"
            },
            action: "Please provide some data"
        }
    });
});

Based upon my code nothing appears to happen when I click the save button on modal. I am utilizing the jquery.validate.js script.

Can someone point me in the right direction?

You have two issues:

1. You're button needs to be set to type="submit" not type="button"

2. Your submit button should be inside your form tag.

See working example Snippet.

$(function() {

  $("#newModalForm").validate({
    rules: {
      pName: {
        required: true,
        minlength: 8
      },
      action: "required"
    },
    messages: {
      pName: {
        required: "Please enter some data",
        minlength: "Your data must be at least 8 characters"
      },
      action: "Please provide some data"
    }
  });
});
