Question

当用户尝试刷新或离开页面时，如何打开Bootstrap模式？模态应显示为：““确定要离开此页面吗？ ”

我正在关注代码：

window.onbeforeunload = function() {
  $('#myModal').modal("show");
  return "Data will be lost if you leave the page, are you sure?";
};

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<!-- jQuery library -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<!-- Latest compiled JavaScript -->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
              <span aria-hidden="true">&times;</span>
            </button>
      </div>
      <div class="modal-body">
        Are you sure you want to navigate away from this page?
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">No I want to stay</button>
        <button type="button" class="btn btn-primary">Yes, I'm sure</button>
      </div>
    </div>
  </div>
</div>

但是使用此代码段，模式会打开，但页面仍会刷新。

当用户尝试离开时，将触发unload事件。但是，如果将DIV用作弹出窗口，则浏览器将在用户有机会阅读它之前导航离开。 要使其保持在那里，您必须使用警报/提示/确认对话框。

绑定到html对我来说效果很好，而不是卸载。

$("html").bind("mouseleave", function () {
  $('#myModal').modal("show");
  $("#okButton").click(function(){
    location.reload();
}); 
  //$("html").unbind("mouseleave");
});

刷新页面时打开BS Modal，询问用户是否确定
