Parent element unable to trigger event due to interference from child elements

Within my HTML document, there is a parent <span> element that contains nested <em> elements. This <span> is styled with a specified width and display:block property using CSS.

Despite a jQuery trigger event being successfully fired on the parent <span>, I have encountered an issue where rolling over one of the child elements triggers the mouse out event, causing my Twitter Bootstrap popover to disappear.

Is there a method to "hide" the child elements in order to prevent this unwanted behavior?

/*** UPDATE WITH CODE SAMPLE **/ Unfortunately, the stopPropagation() method does not resolve this issue.

$("#div").on('mouseover', '.badge', function () {


                //prevent child items from closing our popover
                $(this).on('mouseenter', 'em', function (e) {
                    e.stopPropagation();
                })

                $(this).popover({
                    template: '<div class="popover" role="tooltip"><div class="arrow"></div><h3 class="popover-title"></h3><div class="popover-content"></div></div>',
                    title: 'Title',
                    content:"Some content",
                    html: true,
                    placement: 'auto',
                    trigger:'manual'
                });

                $(this).popover('show');

        });

Answer №1

After implementing the latest code changes, it is unnecessary to use event.stopPropagation() to stop events on child elements. Instead, you can utilize e.target to identify the element that triggered the event and use it to determine the appropriate action to take.

$("#div").on('click','.badge',function (e) {        
         if($(e.target).attr("class") == undefined) {  // em elements don't have a class attribute, so this would return 'undefined'
              return true;
          }

           $(this).popover({
                template: '<div class="popover" role="tooltip"><div class="arrow"></div><h3 class="popover-title"></h3><div class="popover-content"></div></div>',
                title: 'Title',
                content:"Some content",
                html: true,
                placement: 'auto',
                trigger:'manual'
            });

            $(this).popover('show');            
    });

(Note: I have substituted the mouseover event with click in the fiddle to easily test the functionality)

To solve the issue, I devised a clever solution by positioning a transparent background span element over the "badge" and attaching the popover event to it.
