Bootstrap 4工具提示持续存在，看起来很糟糕

您能否运行以下HTML测试用例，以帮助弄清楚在工具提示在按钮上时禁用按钮时，如何使Bootstrap 4 Tooltip消失？有关我的问题的详细信息在代码中列出。

stackoverflow编辑器对将详细信息作为注释不满意，因此我将在此处重复一些详细信息，以使编辑器快乐。当光标徘徊在盘旋上时禁用按钮时，工具提示不会消失，看起来很糟糕。任何帮助。

谢谢

    <h3>Bootstrap 4 Tooltip Persists, Looks Terrible</h3>
    <br> "Other button disabled" scenario works fine.
    <br> First, hover over buttons. Look at tooltips while hovering.
    <br> Then, click button A to disable button B. Works fine:
    <br> - Button B is disabled, and no tooltip.
    <br> - Tooltip still works correctly on button A.
    <br> <br>
    <button type="button" id="button_a" class="btn btn-primary" data-toggle="tooltip" data-trigger="hover" title="Disables Button B" onclick='change_button ("button_b", true);'>
    Button A
    </button>
    <button type="button" id="button_b" class="btn btn-primary" data-toggle="tooltip" data-trigger="hover" title="Disabled by Button A">
    Button B
    </button>
    <br> <br> <hr>
    <br> "Same button disabled" scenario fails.
    <br> First, hover over Button C. Look at the tooltip.
    <br> Then, click button C to disable button C. Messes up:
    <br> - Button C is disabled, so that part is OK.
    <br> - But Button C tooltip persists, looks terrible.
    <br> <br>
    <button type="button" id="button_c" class="btn btn-primary" data-toggle="tooltip" data-trigger="hover" title="Disables Button C" onclick='change_button ("button_c", true);'>
    Button C
    </button>
    <button type="button" id="button_d" class="btn btn-primary" data-toggle="tooltip" data-trigger="hover" title="Enables Button C" onclick='change_button ("button_c", false);'>
    Button D
    </button>
    <br> <br> <hr> <br>
    So if a button is disabled while the cursor is hovering over it, the tooltip persists.
    <strong>
    Could you please explain how to make tooltip go away when Button C is disabled?
    </strong>
    I would prefer if tooltip went away when Button C disabled,
    since that is default behavior of bootstrap disabled buttons.
    And disabled button may later get enabled again, so I do not want to delete title attribute.
    Basically I want bootstrap to behave the same way as when Button B is disabled.
    I have looked around and cannot find how to fix this problem,
    and have tried various things, with no success.
    There are real instances where a button carries out an action,
    and then the button needs to be disabled, so I appreciate the help. Thanks
    </div>
    <script>
    $(document).ready(function(){$('[data-toggle="tooltip"]').tooltip();});
    function change_button (button_id, bool_val) {
    var button_obj = document.getElementById (button_id);
    button_obj.disabled = bool_val;
    }
    </script>
    </body>
    </html>

只需添加到您的 change_button()函数中，逻辑到 hide， disable和 enable工具提示。

$(document).ready(function() {
  $('[data-toggle="tooltip"]').tooltip();
});
function change_button(button_id, bool_val) {
  var button_obj = document.getElementById(button_id);
  button_obj.disabled = bool_val;
  // Disable tooltip
  if (bool_val) {
    $('#' + button_id).tooltip('hide').tooltip('disable');
  } else {
    $('#' + button_id).tooltip('enable');
  }
}

禁用按钮后必须销毁工具提示。

  function change_button(button_id, bool_val) {
    var button_obj = document.getElementById(button_id);
    $("#" + button_id).tooltip("hide");
    button_obj.disabled = bool_val;
  }

我是原始海报。我对Azeos感到惊讶的是，这两个答案之间的行为有所不同，因为我看到测试浏览器没有区别，即11和Chrome74。因此，到目前为止，我对两个答案进行了更多测试。这两个答案在原始帖子中修改change_button函数：

function change_button(button_id, bool_val) { /* A */
  var button_obj = document.getElementById(button_id);
  $("#" + button_id).tooltip("hide");
  button_obj.disabled = bool_val;
  }

////////

function change_button(button_id, bool_val) { /* B */
  var button_obj = document.getElementById(button_id);
  button_obj.disabled = bool_val;
  if (bool_val) {
    $('#' + button_id).tooltip('hide').tooltip('disable');
    }
  else {
    $('#' + button_id).tooltip('enable');
    }
  }

为了澄清，正确的(与其他引导工具提示一致(的行为是：

加载页面
按钮C在悬停的工具提示
单击按钮c
禁用按钮C 和按钮C工具提示消失
单击按钮D
按钮C已启用，并在悬停的悬停上具有工具提示

这是我进一步测试的结果：

IE 11(Windows(：两个答案A和B工作
Chrome 74(Windows(：两个答案A和B工作
歌剧60(Windows(：两个答案A和B工作
Safari 10(Mac(：两个答案A和B工作
Firefox 67(Windows(：回答A失败，B起作用。

使用Firefox 67，按钮C工具提示不会消失，因为Azeos建议可能是一个问题。

当我有更多时间时，我将进行更多测试。另外，我在github上发布到twbs/bootstrap以将其报告为错误，或者至少是一个问题，并将遵循任何答复。

我使用Lambdatest网站进行Safari测试。我直接在Windows 7桌面上进行了其他测试。

任何其他评论或建议都将不胜感激，例如任何使答案B失败或任何智能手机测试的测试。
