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');
                }
            });

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'});

我试过很多以前的答案，真的没有一个对我有效，但这个解决方案管用:

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

他们建议使用锚标记而不是按钮，并注意role="button" + data-trigger="focus" + tabindex="0"属性。

Ex:

<a tabindex="0" class="btn btn-lg btn-danger" role="button" data-toggle="popover" 
data-trigger="focus" title="Dismissible popover" data-content="amazing content">
Dismissible popover</a>

用3.3.6测试，第二次点击是ok的

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

        $(document).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('hide');
                }
            });
        });

jQuery("#menu").click(function(){ return false; });
jQuery(document).one("click", function() { jQuery("#menu").fadeOut(); });

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');
});
