Making Angular Treeview nodes more visually appealing with a bell symbol

I am faced with the task of enhancing a tree view display from (http://alexsuleap.github.io/) by updating a node with a bell icon only after other relevant data on the page has been loaded. The specific icon that needs to be displayed is "glyphicon glyphicon-bell" from the Glyphicons Halflings font in AngularJS.

My initial idea was to update the text content of the tree node and introduce a span element with the 'glyphicon glyphicon-bell' class. However, this approach resulted in the icon being rendered as plain text rather than an actual icon.

What alternative methods can I employ to successfully modify each node within the tree view to show the desired 'glyphicon glyphicon-bell' or bell icon at the beginning of each node?

Answer №1

After much consideration, I opted to utilize JQuery to locate the tree node span and insert a span with the appropriate class before it. Additionally, I incorporated a function to eliminate the bellicon span.

        $scope.addBellIconTo = function(treeNode) {
            var bellIconSpans = $('#' + treeNode.nodeId).prev().find('#bellicon');
            if (bellIconSpans.length == 0) {
                var titleNode = $('#' + treeNode.nodeId).prev().find('.node-name');
                titleNode.before("<span class='glyphicon glyphicon-bell' id='bellicon'></span>");
            }
        }

        $scope.removeBellIconFrom = function(treeNode) {
            var bellIconSpans = $('#' + treeNode.nodeId).prev().find('#bellicon');
            while (bellIconSpans.length > 0) {
                bellIconSpans[0].remove();
            }
        }
