引导5更新:

$(document).on('click', function (e) {
    var
        $popover,
        $target = $(e.target);

    //do nothing if there was a click on popover content
    if ($target.hasClass('popover') || $target.closest('.popover').length) {
        return;
    }

    $('[data-bs-toggle="popover"]').each(function () {
        $popover = $(this);

        if (!$popover.is(e.target) &&
            $popover.has(e.target).length === 0 &&
            $('.popover').has(e.target).length === 0)
        {
            $popover.popover('hide');
        } 
    });
})

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');
});

修改后的接受方案。我的经验是，在一些弹窗被隐藏后，它们必须被点击两次才能再次显示。下面是我所做的，以确保弹窗('hide')不会被已经隐藏的弹窗调用。

$('body').on('click', function (e) {
    $('[data-original-title]').each(function () {
        //the 'is' for buttons that trigger popups
        //the 'has' for icons within a button that triggers a popup
        if (!$(this).is(e.target) && $(this).has(e.target).length === 0 && $('.popover').has(e.target).length === 0) {
            var popoverElement = $(this).data('bs.popover').tip();
            var popoverWasVisible = popoverElement.is(':visible');

            if (popoverWasVisible) {
                $(this).popover('hide');
                $(this).click(); // double clicking required to reshow the popover if it was open, so perform one click now
            }
        }
    });
});

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元素中

data-trigger="focus"

这个解决方案很有效:

$("body")   .on('click'     ,'[data-toggle="popover"]', function(e) { 
    e.stopPropagation();
});

$("body")   .on('click'     ,'.popover' , function(e) { 
     e.stopPropagation();
});

$("body")   .on('click'  , function(e) {
        $('[data-toggle="popover"]').popover('hide');
});
