jquery - Bootstrap 4 工具提示仍然存在，看起来很糟糕

问题描述

您能否运行以下 html 测试用例，以帮助弄清楚当工具提示在按钮上方时按钮被禁用时如何使引导程序 4 工具提示消失？代码中列出了有关我的问题的详细信息。

stackoverflow 编辑器不满意我将详细信息作为注释放入代码中，因此我将在这里重复一些细节以尝试使编辑器满意。当光标悬停在按钮上时禁用按钮时，工具提示不会消失，而且看起来很糟糕。任何帮助表示赞赏。

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

    <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>

解决方案

只需将change_button()逻辑hide和工具提示添加到您disable的函数中。enable

$(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');
  }
}
