3、页面加载监听滚动事件：
mounted() { window.addEventListener(‘scroll‘, this.handleScroll); },
4、页面销毁移除监听：
destroyed() { window.removeEventListener(‘scroll‘, this.handleScroll); },
5、methods：
handleScroll () { var scrollTop = window.pageYOffset || document.documentElement.scrollTop || document.body.scrollTop; //获取页面滚动位置 var offsetTop = document.querySelector(‘#searchBar‘).offsetTop; // 获取 div 初始位置 if (scrollTop > offsetTop) { //判断高度 this.searchBarFixed = true; } else { this.searchBarFixed = false; } },
6、style ：
.isFixed{ position: fixed; background-color: #Fff; top: 0; width: 1200px !important; margin: auto; z-index: 3; }
