完全通过js來配置  

        <p><a id="YOUR_BUTTON_FOR_POPOVER" class="btn btn-primary" role="button"  href="#">Click me</a>, then click somewhere else afterwards !</p>

  $('#YOUR_BUTTON_FOR_POPOVER').popover({
        animation: true,
        placement: 'bottom',
        trigger: 'focus',
        title: 'See?',
        content: 'Now try clicking outside !'
    }).on("click", function() {
        $(this).popover("show");

先进行配置，当调用的时候直接调用show就可以
