在模态中的 div 内打开 link

Opening a link inside a div in the modal

我有一个模式,其中有 2 个 <a> 标签。当用户单击 link 时,link 应该在同一模式的相同 div 中打开,而 不在选项卡中

为此我尝试了:

$(document).ready(function() {
  $("#help_modal a").each(function() {
    $("#help_modal").load($(this).attr("href"));
  });
});
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
<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://whosebug.com" class="btn btn-block btn-lg btn-secondary">Open Whosebug</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 link 在同一个选项卡中打开...

更新

我也试过, but it also didn't work for me after .

我设法用一些 javascript 和 html 'object' 标签实现了你想要的:

我用 toReplace 变量的内容替换了你模态主体的内容,包含一个 html 'object' 元素,用于嵌入外部 link.

let el = document.getElementById("test");
let elToReplace = document.getElementById("help_modal");
let toReplace = "<object type=\"text/html\" data=\"https://gnu.org/\" width=\"100%\" height=\"600px\" style=\"overflow:auto;border:5px ridge blue\"> </object>";

function replaceInner() {
    elToReplace.innerHTML = toReplace;
}

el.addEventListener("click", () => { replaceInner(); }, false);

回答你的comment

如果您检查控制台,而 运行 JSFiddle 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'".

也就是说,

由于设置了内容安全策略,内容被禁止在 IFRAME 中显示。托管 whosebug.com 的 Web 服务器配置为将 HTTP header 添加到响应 object。具体来说,他们将 Content-Security-Policy 标签设置为 frame-ancestors 'self'。您无法使用 IFRAME 将他们的页面嵌入到您自己的页面中。

回答你的question

Learner's answer 也是一个不错的选择。 (+1)

但我更喜欢有不同的 iframe(s) 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();
  });

});
