Question

当我打开模态时，默认情况下会打开第一个选项卡，如果单击任何其他选项卡，第一个选项卡将关闭，单击的选项卡将打开，但是如果我再次单击第一个选项卡，则两个选项卡都会打开。这是html代码

    <body>
<button id="modalButtton" type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>   
<div class="modal fade" id="myModal" role="dialog">

        </div>
      </div>

    </div>
  </div> <!-- end of Modal -->

</body>

这是jquery代码

$('#myModal').on('hidden.bs.modal', function () {
$('.collapse').collapse('hide');
});
$('#myModal').on('shown.bs.modal', function () {
$('#collapseOne').collapse('show');
});



$('#accordion').find('.panel-default:has(".in")').addClass('panel-primary');

$('#accordion').on('show.bs.collapse', function (e) {
$(e.target).closest('.panel-default').addClass(' panel-primary');
}).on('hide.bs.collapse', function (e) {
$(e.target).closest('.panel-default').removeClass(' panel-primary');
})

Answer 1

您还需要在$('.collapse').collapse('hide');：

的函数内调用show.bs.collapse

$('#accordion').on('show.bs.collapse', function(e) {
  $(e.target).closest('.panel-default').addClass(' panel-primary');
  $('.collapse').collapse('hide');
}).on('hide.bs.collapse', function(e) {
  $(e.target).closest('.panel-default').removeClass(' panel-primary');
})
