vue router-link路由跳转时切换导航栏样式

router-link路由跳转切换导航栏样式

• 在css中定义该class对应的router-link-active样式
• 设置首页为默认状态：添加exact属性

左右布局 高度撑满屏幕 高度超出显示内部滚动条

    <div class="container">
        <div class="countLeft">
            <ul class="nav">
                <li>
                    <router-link to="/checkbox" exact>
                        el-checkbox-group表格外部的全选/反选
                    </router-link>
