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();
                }
            }
        }
    }
});

使用bootstrap 2.3.2，你可以将触发器设置为“focus”，它就可以工作了:

$('#el').popover({trigger:'focus'});

演示:http://jsfiddle.net/nessajtr/yxpM5/1/

var clickOver = clickOver || {};
clickOver.uniqueId = $.now();

clickOver.ClickOver = function (selector, options) {
    var self = this;

    //default values
    var isVisible, clickedAway = false;

    var callbackMethod = options.content;
var uniqueDiv = document.createElement("div");
var divId = uniqueDiv.id = ++clickOver.uniqueId;
uniqueDiv.innerHTML = options.loadingContent();

options.trigger = 'manual';
options.animation = false;
options.content = uniqueDiv;

self.onClose = function () {
    $("#" + divId).html(options.loadingContent());
    $(selector).popover('hide')
    isVisible = clickedAway = false;
};
self.onCallback = function (result) {
    $("#" + divId).html(result);
};

$(selector).popover(options);

//events
$(selector).bind("click", function (e) {
    $(selector).filter(function (f) {
        return $(selector)[f] != e.target;
    }).popover('hide');

    $(selector).popover("show");
    callbackMethod(self.onCallback);

    isVisible = !(clickedAway = false);
});

$(document).bind("click", function (e) {
    if (isVisible && clickedAway && $(e.target).parents(".popover").length == 0) {
        self.onClose();
        isVisible = clickedAway = false;
    } else clickedAway = true;
});

}

这是我的解。

只需将此属性添加到html元素，以关闭弹出窗口在下次点击。

data-trigger="focus"

根据最高的两个答案，我有一个小方法:

<span class="btn btn-info btn-minier popover-info" data-rel="popover"
                                              data-placement="bottom" data-html="true" title=""
                                              data-content="popover-content"
                                              data-original-title="popover-title">
                                            <i class="ace-icon fa fa-info smaller-100"></i>
                                        </span>

            $('[data-rel=popover]').popover({html: true});
            $(document).on("shown.bs.popover", '[data-rel=popover]', function () {
                $('[data-rel="popover"][popover-show="1"]').popover('hide');
                $(this).attr('popover-show', '1');
            });
            $(document).on("hidden.bs.popover", '[data-rel=popover]', function () {
                if ($(this).attr('popover-show') === '0') {
                    // My important fix: using bootstrap 3.4.1, if hide popover by .popover('hide') and click to show, popover internal treat it is already shown and dispatch hidden event immediately without popover anything.
                    $(this).popover('toggle');
                } else {
                    $(this).attr('popover-show', '0');
                }
            });
            $('html').on('click', function (e) {
                if (typeof $(e.target).data('original-title') == 'undefined'
                    && typeof $(e.target).parent().data('original-title') == 'undefined'
                    && !$(e.target).parents().is('.popover.in')) {
                    $('[data-rel="popover"][popover-show="1"]').popover('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。
