How to use the d3-selection.event.preventDefault function in d3-selection

function downloadMember(d) {
        d3_event.preventDefault();

        // display the loading indicator
        d3_select(this.parentNode).classed('tag-reference-loading', true);
        context.loadEntity(d.id, function() {
            updateDisclosureContent(_contentSelection);
        });
    }

// if the node is collapsed and has children expand
                if (!node.data.expanded && Array.isArray(node.data.children) && node.data.children.length > 0) {
                    return this.expand(node);

                return this.focusChild(node);

            case UP_ARROW:
                event.preventDefault();

            case LEFT_ARROW:
                event.preventDefault();
                return this.focusPreviousSibling(node);

            case ENTER:
                return this.toggle(node);
        }
    }

            _expanded = !_expanded;

            if (_updatePreference) {
                context.storage('disclosure.' + key + '.expanded', _expanded);
