对于任何人寻找一个解决方案，工作与Bootstrap 5和没有jQuery，即使弹出窗口是动态生成(即手动触发):

document.querySelector('body').addEventListener('click', function(e) {
    var in_popover = e.target.closest(".popover");

    if (!in_popover) {
        var popovers = document.querySelectorAll('.popover.show');

        if (popovers[0]) {
            var triggler_selector = `[aria-describedby=${popovers[0].id}]`;

            if (!e.target.closest(triggler_selector)) {
                let the_trigger = document.querySelector(triggler_selector);
                if (the_trigger) {
                    bootstrap.Popover.getInstance(the_trigger).hide();
                }
            }
        }
    }
});

$('html').on('click.popover', function (e) {
    var allpopins = $('.popover.in');
    if (allpopins.has(e.target).length > 0 &&
        !$('.btn', allpopins).is(e.target))
        return;
    // recognise pop-up 
    var id = $(e.target).attr('aria-describedby');
    var popin = $("#" + id);
    //on any button click in entire pop-up hide this pop-ups
    $(popin).on(".btn", function () { popin.remove(); });
    // on any place out of entire popup hide all pop-ups 
    $('.popover.in').not(popin).remove();
});

这是我最好的性能解决方案。欢呼。

            }
        }
    }
});

我做了一个jsfiddle来告诉你如何做到这一点:

http://jsfiddle.net/3yHTH/

其思想是在单击按钮时显示弹出窗口，在单击按钮外时隐藏弹出窗口。

HTML

<a id="button" href="#" class="btn btn-danger">Click for popover</a>

JS

$('#button').popover({
    trigger: 'manual',
    position: 'bottom',
    title: 'Example',
    content: 'Popover example for SO'
}).click(function(evt) {
    evt.stopPropagation();
    $(this).popover('show');
});

$('html').click(function() {
    $('#button').popover('hide');
});

只需将此属性添加到元素中

data-trigger="focus"

这基本上不是很复杂，但有一些检查要做，以避免故障。

演示(jsfiddle)

var $poped = $('someselector');

// Trigger for the popover
$poped.each(function() {
    var $this = $(this);
    $this.on('hover',function() {
            var popover = $this.data('popover');
            var shown = popover && popover.tip().is(':visible');
            if(shown) return;        // Avoids flashing
            $this.popover('show');
    });
});

// Trigger for the hiding
 $('html').on('click.popover.data-api',function() {
    $poped.popover('hide');
});
