How do I validate all form fields in a div using parsley.js?

Question

I have a div with a form field and a button that I would like to have parsley validate all the form fields in that div that have the proper data-validate attribute. I need it to work no matter how many form fields are in the div. So it needs to work on inputs, textareas, and select fields.

HTML:

<div id="parsley-div">
  <div class="form-group">
    <label for="city">City</label>
    <input id="city-test" type="text" class="form-control" data-parsley-required data-parsley-required-message="Please enter a city name.">
  </div>
  <button class="btn btn-primary">Save Changes</button>
</div>

JS:

$('#parsley-div').find('button').click(function(){
  $('#parsley-div').parsley().validate();
});

Unfortunately, this isn't working. I noticed it works if there is a form tag around the form fields, but I need it to be a div. I have created a JSFiddle that shows both cases: https://jsfiddle.net/8rkxzjx1/2/

How can I have parsley validate all form fields with data-parsley attributes within a specified div? If possible, please edit the JSFiddle to show the correct implementation. Thank you.

Edit:

I figured out this works, but it doesn't feel very efficient:

$('#parsley-div').find( "input, textarea, select" ).each(function (index, value) {   
  $(this).parsley().validate();
});

You could use

$('#parsley-div :input:not(:button)').parsley().validate();

See fiddle.

Edit

Looks like the above code won't work. The following can be used as the OP suggested.

$('#parsley-div :input:not(:button)').each(function (index, value) { 
  $(this).parsley().validate();
});

Here is the new fiddle.

Or the content can be wrapped in a form element and then be validated as follows:

$("#parsley-div").wrap("<form id='parsley-form'></form>");
$('#parsley-div').find('button').click(function() {
    $('#parsley-form').parsley().validate();
});

Or since the OP does not want to have a form element in Dom, content can be wrapped in a form element and then the form can be removed after validation.

$('#parsley-div').find('button').click(function() {
    $("#parsley-div").wrap("<form id='parsley-form'></form>");
    $('#parsley-form').parsley().validate();
    $("#parsley-div").unwrap();
});
