模态在Safari以外的所有浏览器中打开

Question

我有一个页面，其中有一个浮动的可拖动模式，允许我在模式打开时访问背景。 以下功能适用于Safari以外的所有浏览器。 有任何想法吗？ 以下小提琴在Safari中失败。

的CSS

#myModal {
  position: relative;
}

.modal-dialog {
  position: fixed;
  width: 50%;
  margin: 0;
  padding: 10px;
}

的HTML

<button id="openModal">Show Modal</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h4 class="modal-title" id="myModalLabel">Draggable Modal</h4>
      </div>
      <div class="modal-body">
        Modal Body
      </div>
      <div class="modal-footer">
        <button class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

脚本

$('#openModal').click(function() {
  if (!($('.modal.in').length)) {
    $('.modal-dialog').css({
      top: 0,
      left: 0
    });
  }
  $('#myModal').modal({
    backdrop: false,
    show: true
  });

  $('.modal-dialog').draggable({
    handle: ".modal-header"
  });
});

您需要从#myModal元素中删除相对位置。

 $('#openModal').click(function() { if (!($('.modal.in').length)) { $('.modal-dialog').css({ top: 0, left: 0 }); } $('#myModal').modal({ backdrop: false, show: true }); $('.modal-dialog').draggable({ handle: ".modal-header" }); }); 

 .modal-dialog { position: fixed; width: 50%; margin: 0; padding: 10px; }
