})

使用Matt Lockyer的代码，我做了一个简单的重置，所以dom不会被隐藏的元素覆盖。

小提琴:http://jsfiddle.net/mrsmith/Wd2qS/

    $('body').on('click', function (e) {
    //hide popover from dom to prevent covering elements
    $('.popover').css('display', 'none');
    //bring popover back if trigger element is clicked
    $('[data-toggle="popover"]').each(function () {
        if ($(this).is(e.target) && $(this).has(e.target).length === 0 && $('.popover').has(e.target).length === 0) {
            $('.popover').css('display', 'block');
        }
    });
    //hide popover with .popover method
    $('[data-toggle="popover"]').each(function () {
        //the 'is' for buttons that trigger popups
        //the 'has' for icons within a button that triggers a popup
        if (!$(this).is(e.target) && $(this).has(e.target).length === 0 && $('.popover').has(e.target).length === 0) {
            $(this).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
            }
        }
    });
});

$(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');
        } 
    });
})

如果你使用选择器委托创建弹出窗口，那么'hide'方法似乎不起作用，而必须使用'destroy'。

我是这样做的:

$('body').popover({
    selector: '[data-toggle="popover"]'
});

$('body').on('click', function (e) {
    $('[data-toggle="popover"]').each(function () {
        //the 'is' for buttons that trigger popups
        //the 'has' for icons within a button that triggers a popup
        if (!$(this).is(e.target) && $(this).has(e.target).length === 0 && $('.popover').has(e.target).length === 0) {
            $(this).popover('destroy');
        }
    });
});

关于这个课题JSfiddle

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');
                }
            });
