Question

I have been trying to find a way to dynamically modify the content of a bootstrap popover using Javascript, however the method i have come across so far have not worked :

<!--object with the popover-->
<input id="popoverlist" type="text" name="poplist" placeholder="Enter data"  data-html="true" data-content="" rel="popover" data-placement="bottom" data-original-title="pop list" >

$('#popoverlist').popover({
                offset: 10,
                trigger: 'manual',
                animate: false,
                html: true,
                placement: 'left',
                template: '<div class="popover" onmouseover="$(this).mouseleave(function() {$(this).hide(); });"><div class="arrow"></div><div class="popover-inner"><h3 class="popover-title"></h3><div class="popover-content"><p></p></div></div></div>'

            }).click(function(e) {
                e.preventDefault() ;
            }).mouseenter(function(e) {
                $(this).popover('show');
            });

The methods i have been trying to use to set the html content are :

$('#popoverlist').data('bs.popover').html("<p>New content</p>");
//and using the inner HTML
document.getElementsByClassName("popover-content")[0].innerHTML = '<p>New content</p>';

However neither of those methods change the html data content. I would appreciate any help on this to point me in the correct direction :)

Your second idea works, but you need to invoke it after the popover-content has been created.

The popover isn't created until the first time it is shown, and is recreated after each call to show . Thus, you need to change the content after $(this).popover('show'); .

I've included a snippet showing this in action:

 $('#popoverlist').popover({ offset: 10, trigger: 'manual', animate: false, html: true, placement: 'bottom', template: '<div class="popover" onmouseover="$(this).mouseleave(function() {$(this).hide(); });"><div class="arrow"></div><div class="popover-inner"><h3 class="popover-title"></h3><div class="popover-content"><p></p></div></div></div>' }).click(function(e) { e.preventDefault() ; }).mouseenter(function(e) { $(this).popover('show'); // dynamically change content after show document.getElementsByClassName("popover-content")[0].innerHTML = '<p>New content</p>'; });
