                        len = tabCardCollection.length;
 
                    for(var i = 0; i < len; i++) {
                        tabCardCollection[i].style.display = "none";
                        this.tabsName[i].isActive = false;
                    }
                    this.tabsName[tabIndex].isActive = true;
                    tabCardCollection[tabIndex].style.display = "block";
