为什么我的 Bootstrap 5 弹出窗口在关闭并重新打开它所在的模式后失去了打开焦点的能力？

Question

我的 Bootstrap 5 模式和放置在其上的弹出窗口有问题。

在我的 HTML 中，我有以下内容，当用户将鼠标悬停在按钮上时，它会正确显示。弹出窗口显示“您确定吗？”键入提示并建议用户单击按钮（悬停）以继续。单击该按钮即可获取焦点并保持弹出窗口打开，直到再次单击或单击离开该元素。

这允许鼠标指针进入弹出窗口内容并单击“继续”按钮。

这就是我想要的东西：https://bootstrap-confirmation.js.org，但有一些有关按钮悬停时显示的功能的更多详细信息...

不管怎样，效果很好！第一次...如果模式被隐藏然后再次显示，则只有弹出窗口触发器的悬停部分起作用，并且单击按钮确实会触发它的侦听器，但弹出窗口拒绝保持打开状态（根据“焦点”触发器） )..

请帮忙，这让我发疯！

令人沮丧的是，下面的代码片段似乎确实有效，尽管在关闭并重新打开模式时会抛出错误，我不确定为什么？

编辑添加：Chrome 和 Safari 中均存在该问题，Safari 将创建控制台错误：

locate_dev.js 第 394 行的代码是弹出窗口初始化，可疑：

const locateModal = document.getElementById('locateScreen')
locateModal.addEventListener('shown.bs.modal', event => {

似乎会产生错误，因为弹出窗口的内容在模式被隐藏和重新显示之间的某个时刻消失。

考虑：

var locateBtnClosePopover = new bootstrap.Popover($('#locate-btn-close'), {
            html: true,
            sanitize: false,
            customClass: 'locate-footer-popover',
            title: "Are you sure?",
            content: $('[data-name="close-btn-popover-content"]')
        });

测试 $('[data-name="close-btn-popover-content"]') 根本不返回任何内容。在初始化模式时（在初始化弹出窗口之前）手动将其附加到父 div 也没有帮助。

解决了！

我从按钮 HTML 中删除了 data-bs-trigger="hover focus" 属性并使用：

locateBtnClosePopover = new bootstrap.Popover($('#locate-btn-close'), {
            html: true,
            sanitize: false,
            customClass: 'locate-footer-popover',
            title: "Are you sure?",
            trigger: 'hover focus',
            content: $('[data-name="close-btn-popover-content"]')
        });

我还需要在 'hidden.bs.modal' 上重建 $('[data-name="close-btn-popover-content"]') 中的内容，如下所示：

locateModal.addEventListener('hidden.bs.modal', event => {
        
        // At this point the  $('[data-name="close-btn-popover-content"]') has been removed....
        // Lets add it back in
        $('#popover-close-btn-holder').html('


You can choose to close or save this session at the next screen.
Click the button to continue...


CancelContinue

');
        
    });
