jquery - 在模态中打开 div 内的链接

Question

我有一个模态，其中有 2 <a>标签。当用户单击链接时，应在同一模式的同一 div 中打开该链接，并且不在选项卡中。

为此我尝试过:

$(document).ready(function() {
  $("#help_modal a").each(function() {
    $("#help_modal").load($(this).attr("href"));
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>

<div class="container">
  <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal">
    Open modal
  </button>

  <!-- The Modal -->
  <div class="modal" id="myModal">
    <div class="modal-dialog">
      <div class="modal-content">

        <!-- Modal Header -->
        <div class="modal-header">
          <h4 class="modal-title">Modal Heading</h4>
          <button type="button" class="close" data-dismiss="modal">&times;</button>
        </div>

        <!-- Modal body -->
        <div class="modal-body" id="help_modal">
          <a href="https://google.com" class="btn btn-block btn-lg btn-primary">Open Google</a>
          <a href="https://stackoverflow.com" class="btn btn-block btn-lg btn-secondary">Open Stackoverflow</a>
        </div>

        <!-- Modal footer -->
        <div class="modal-footer">
          <button type="button" class="btn btn-danger" data-dismiss="modal">Close</button>
        </div>

      </div>
    </div>
  </div>

</div>

但是链接正在同一选项卡中打开...

我也尝试过this answer ，但在 this comment 之后它对我也不起作用.

回答您的comment :

如果您在运行 JSFiddle 时检查控制台它说，

Refused to display 'Opening a link inside a div in the modal' in a frame because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'self'".

这意味着，

由于设置了内容安全策略，内容被禁止在 IFRAME 内显示。托管 stackoverflow.com 的 Web 服务器配置为向响应对象添加 HTTP header 。具体来说，他们将 Content-Security-Policy 标签设置为框架祖先“self”。您无法使用 IFRAME 将他们的页面嵌入到您自己的页面中。

<强> Learner's answer也是一个不错的选择。 (+1)

但我更喜欢有不同的iframe并通过按钮显示它们。

$(document).ready(function() {
  $(".modal_button_example_com_self").click(function() {
    $('.modal_button_self').hide();
    $('#example_com').attr("style", "");
  });

  $(".modal_button_example_net_self").click(function() {
    $('.modal_button_self').hide();
    $('#example_net').attr("style", "");
  });

  $(".close_self").click(function() {
    $('.modal_button_self').attr("style", "");
    $('#example_com').hide();
    $('#example_net').hide();
  });

});
