将函数绑定到Bootstrap Modal Cancel

<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">Modal标题</h4>
      </div>
      <div class="modal-body">
        Modal内容
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">取消</button>
        <button type="button" class="btn btn-primary">保存</button>
      </div>
    </div>
  </div>
</div>

$(document).ready(function() {
  $('#myModal').on('hidden.bs.modal', function() {
    // 在这里执行你的取消操作函数
    cancelFunction();
  });
});

function cancelFunction() {
  // 执行取消操作的代码
  console.log("取消按钮被点击");
}
