Bootstrap popover content cannot changed dynamically

Solution 1:

If you grab the popover instance like this:

var popover = $('.reply').data('bs.popover');

Then, to redraw the popover, use the .setContent() method:

popover.setContent();

I found out browsing the source: https://github.com/twitter/bootstrap/blob/master/js/popover.js

So, in your example, try:

thisVal.attr('data-content',data).data('bs.popover').setContent();

Update

The setContent() method also removes the placement class, so you should do:

var popover = thisVal.attr('data-content',data).data('bs.popover');
popover.setContent();
popover.$tip.addClass(popover.options.placement);

Yes you can, in fact the easiest way haven't been suggested yet.

Here's my way ->

    var popover = $('#example').data('bs.popover');
    popover.options.content = "YOUR NEW TEXT";

popover is an object if you want to know more about it, try to do console.log(popover) after you define it to see how you can use it after !

EDIT

As of Bootstrap 4 alpha 5, the data structure is a bit different. You'll need to use popover.config.content instead of popover.options.content
