shown.bs.popover引导事件
当弹出窗口完全可见时，将触发shown.bs.popover事件。
首先，使用以下代码在按钮单击上显示弹出窗口-
$(".btn-default").click(function(){
$("[data-toggle='popover']").popover('show');
});之后，触发popovershown.bs.popover事件并生成警报-
$("[data-toggle='popover']").on('shown.bs.popover', function(){
alert('Popover is completely visible!');
});您可以尝试运行以下代码来实现show.bs.popover事件-
