Month select in datepicker inside a bootstrap-modal won't work in Firefox

Question

The month select in the datepicker doesn't work in FireFox if it is within a bootstrap-modal.

<button class="btn" id="btn">Click Me</button>

<div class="modal hide" id="modal" tabindex="-1">
    <div class="modal-body">
        <input type="text" id="datepicker" />        
    </div>
</div>

JavaScript:

$("#datepicker").datepicker({"changeMonth": true});

$('#btn').click(function() {
    $("#modal").modal('show');
});

Here is a minified example: http://jsfiddle.net/nKXF2/

I found a simmilar twitter-bootstrap github issue: https://github.com/twbs/bootstrap/issues/5979

Answer 1

I found two fixes for this bug:

Fix 1: If you remove the tabindex attr in div.modal, the month select works just fine. The only issue I had with this solution is that, on IE (any version) you still need to double-click the month dropwdown for it to open up.

Fix2: The second solution you can find at: http://jsfiddle.net/nKXF2/1/ By overriding the enforceFocus function which was proposed in this question also, you get the month dropdown to work again.

$('#modal').on('show', function () {
    $.fn.modal.Constructor.prototype.enforceFocus = function () { };
});

I think this second one is the best.
