先来看下怎么样动态加载nav导航
html代码
<el-menu :default-active="$router.path" router class="el-menu-demo" mode="horizontal" @select="handleSelect" background-color="#545c64" text-color="#fff" active-text-color="#ffd04b">
<label v-for="(item,index) in navData" :key="index">
<el-menu-item :index=item.url>
<i :class=item.icon></i>
<span slot="title">{{item.name}}</span>
</el-menu-item>
</label>
</el-menu>
js模拟从后台获取的导航数据
navData: [
{
name: "ECharts",
url: "/Echarts",
icon: "el-icon-menu"
},
{
name: "菜单选项2",
url: "2",
icon: "el-icon-tickets"
},
{
name: "菜单选项3",
url: "3",
icon: "el-icon-message"
},
{
name: "菜单选项4",
url: "4",
icon: "el-icon-phone-outline"
},
{
name: "菜单选项5",
url: "5",
icon: "el-icon-star-off"
},
{
name: "菜单选项6",
url: "6",
icon: "el-icon-setting"
}
]

这个动态生成的复杂导航因为有些测试需要做，所以菜单名字就一直没有改，不影响实现效果
没看明白或者是有更好方法的小伙伴们可以私信我
这里卿洋 愿喜❤️
