Vue中面包屑导航功能和实现---面包屑导航--$route.matched

 DOM部分：

<el-breadcrumb class="breadcrumb" separator="/">
            <el-breadcrumb-item 
                v-for='(name,index) in matchedArr'
                :key='index'
                >
                {{ $t(`commons.${name}`)}}
            </el-breadcrumb-item>
</el-breadcrumb>

script部分：

computed:{
        matchedArr(){
            let temp = [],temps = [];
            this.$route.matched.filter((item,index,self) => {
                // if(item.meta.title){
                //     const title = item.meta.title;
                //     temp.push(title);
                // }
                if(item.name){
                    const name = item.name;
                    temp.push(name);
                }
            });
            temp.filter((item,index,self) => {
                if(!temps.includes(item)){
                    temps.push(item);
                }
            })
            return temps;
        }
}

 路由文件举例：

{
    path: "/fundManage",
    name: "fundManage",
    meta: {
      title: "资金管理",
      icon: "iconpay3",
    },
    component: Layout,
    children: [
      {
        path: "fundList",
        name: "fundList",
        meta: {
          title: "资金流水",
          routerType: "leftmenu",
        },
        component: () => import("@/page/fundList/fundList"),
      },
      {
        path: "chinaTabsList",
        name: "chinaTabsList",
        meta: {
          title: "区域投资",
          routerType: "leftmenu",
        },
        component: () => import("@/page/fundList/chinaTabsList"),
