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');
});

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();
                }
            }
        }
    }
});

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"

参考来自https://getbootstrap.com/docs/3.3/javascript/#dismiss-on-next-click

我只是在新弹出窗口显示之前删除其他活动弹出窗口(bootstrap 3):

$(".my-popover").popover();

$(".my-popover").on('show.bs.popover',function () {
    $('.popover.in').remove();
});              

$('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。

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。
