Load a Bootstrap popover content with AJAX. Is this possible?

Works ok for me:

$('a.popup-ajax').popover({
    "html": true,
    "content": function(){
        var div_id =  "tmp-id-" + $.now();
        return details_in_popup($(this).attr('href'), div_id);
    }
});

function details_in_popup(link, div_id){
    $.ajax({
        url: link,
        success: function(response){
            $('#'+div_id).html(response);
        }
    });
    return '<div id="'+ div_id +'">Loading...</div>';
}

See my blog post for the working solution: https://medium.com/cagataygurturk/load-a-bootstrap-popover-content-with-ajax-8a95cd34f6a4

First we should add a data-poload attribute to the elements you would like to add a pop over to. The content of this attribute should be the url to be loaded (absolute or relative):

<a href="#" title="blabla" data-poload="/test.php">blabla</a>

And in JavaScript, preferably in a $(document).ready();

$('*[data-poload]').hover(function() {
    var e=$(this);
    e.off('hover');
    $.get(e.data('poload'),function(d) {
        e.popover({content: d}).popover('show');
    });
});

off('hover') prevents loading data more than once and popover() binds a new hover event. If you want the data to be refreshed at every hover event, you should remove the off.

Please see the working JSFiddle of the example.
