vue+element 进入不同路由页面(二级页面),让相应的左侧菜单


路由配置
{
path: '/finance',
name: 'Finance',
meta: {
title: '财务'
},
component: () =>
import('@/components/Finance'),
redirect: '/finance/code/code',
children: [{
path: '/finance/code',
name: 'financeindex',
meta: {
title: '税收配置'
},
redirect: '/finance/code/code',
component: () =>
import('@/components/finance/financeindex'),
children: [{
path: '/finance/code/code',
name: 'FinanceCode',
hidden: false,
active:'/finance/code', //这里是在左侧菜单显示并且需要选中的
meta: {
title: '税收编码(金税)'
},
component: () =>
import('@/components/finance/code/Code'),
},
{
path: '/finance/code/codeimportrecord', // 这个路由进入的界面是 税收编码(金税)的二级页面, 当进入这个页面的时候,需要菜单中的税收编码(金税)显示选中
    name: 'FinanceCodeImportRecord',
hidden: true,
meta: {
title: '税收编码导入记录'
  },
component: () =>
import('@/components/finance/code/CodeImportRecord'),
},

hidden: false,
active:'/finance/classcode', //为了省事,只给需要在左侧显示的路由添加active属性
meta: {
title: '分类税收编码确认'
},
component: () =>
import('@/components/finance/classCode/ClassCode'),
},
]
}, ]

</el-menu>
</div>
</template>
<script>
js
 data() {
return {
navs:[],
show:null //初始化上面:default-active绑定的值
}
},
created() { //// 页面载入的时候,拿到url,用/拆开,然后拼起来前两个路径,并且赋值, 这个时候show对应的就是路由表中的 avtive,
let route=this.$route.path.split('/')
let vueRouter=this.$router.options.routes.filter(router=>{return router.path=='/'})[0].children
let filterVuerouter=vueRouter.filter(router=>{return '/'+route[1] == router.path })
this.navs=filterVuerouter[0].children
console.log(this.navs)

let router ='/'+route[1]+'/'+route[2]
console.log(router)
this.show=router
// console.log(this.show)
},
mounted() {

},
