您能否运行以下 html 测试用例，以帮助弄清楚如何在工具提示位于按钮上方时禁用按钮时使 bootstrap 4 工具提示消失？有关我的问题的详细信息列在代码中。
stackoverflow 编辑器不喜欢我将细节作为注释放入代码中，因此我将在这里重复一些细节以试图让编辑器高兴。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>

只需将逻辑添加到您的change_button() 函数中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');
}
