Inconsistent Functionality of Bootstrap Popover

I am experiencing an issue with the bootstrap Popover feature. It seems to work inconsistently - sometimes it works and other times it doesn't. I am using it to create a popover that displays a user's information when a visitor hovers over the user's name. The page is dynamically generated using ajax, so initially I thought the problem might be related to content being loaded after the popover initiation. However, the strange thing is that it only works intermittently.

$(document).on('mouseenter', '.postusername', function(e){
    var userid = this.parentElement.parentElement.children[0].innerHTML;
    var element = this;
    if(userid)
    {
        $.get('/Requests/getuinfo.php', {id : userid})
        .done(function(data){
            var uinfo = JSON.parse(data);
            $(element).popover({
                html : true,
                template : '<div class="popover" role="tooltip"><div class="arrow"></div><div class="popover-content"></div></div>',
                content : '<div class="popover-holder" style="background-image:url(\'/Style/Media/CoverPics/' + uinfo.coverpic + '\');">' + uinfo.name 
                + '</div>',
                placement: 'auto'
            });
            $(element).popover('show');
        });
    }
});

$(document).on('mouseleave', '.postusername', function(e){
    $(this).popover('hide');
});

That's the JavaScript code I have implemented.

Answer №1

After investigating the issue, it was discovered that attempting to create a new popover for an existing element was causing the problem. The solution involved removing the popover after hiding it, which resolved the issue.

However, a better approach would be to fix the problem without removing the popover. This way, user information will only be retrieved once per user...

var usersInfo = [];

$(document).on('mouseenter', '.postusername', function(e){
    var userId = this.parentElement.parentElement.children[0].innerHTML;
    var targetElement = this;
    if(userId)
    {
        if (usersInfo.indexOf(userId) === -1) {
            $.get('/Requests/getuinfo.php', {id : userId})
            .done(function(data){
                var userInfo = JSON.parse(data);
                boo = userInfo;
                $(targetElement).popover({
                    html : true,
                    template : '<div class="popover" role="tooltip"><div class="arrow"></div><div class="popover-content"></div></div>',
                    content : '<div class="popover-holder" style="background-image:url(\'/Style/Media/CoverPics/' + userInfo.coverpic + '\');">' + userInfo.name 
                    + '</div>',
                    placement: 'auto'
                });
                $(targetElement).popover('show');
                usersInfo.push(userId);
            });
        }
        else {
            $(targetElement).popover('show');
        }
    }
});

$(document).on('mouseleave', '.postusername', function(e){
    $(this).popover('hide');
});

This approach maintains an array of user ids for which information has been retrieved, ensuring duplicate calls are avoided.
