本文实例为大家分享了vue+elementUI实现动态面包屑的具体代码，供大家参考，具体内容如下
引言
后台管理系统中，经常会出现需要面包屑的情况，但是又不想每个页面都实现一个，这样不方便维护，因此封装了面包屑组件，方便在页面使用
封装组件
{{ item.meta.title }} {{ item.meta.title }}
页面使用
four
路由文件参考
// router/index.ts
import Vue from 'vue';
import VueRouter from 'vue-router';
import Login from '@/views/login/index.vue';
import Layout from '@/layout/index.vue';
Vue.use(VueRouter);
/**
* hidden 表示是否需要在侧边导航栏出现 ，true表示不需要
* isFirst 表示是否只有一级权限，只出现在只有一个子集，没有其他孙子集
* 当权限拥有多个子集或者孙子集，一级权限需要加上 meta
* 二级权限拥有子集，也必须有 meta
*/
// 基础路由
export const constantRoutes = [
{
path: '/redirect',
component: Layout,
hidden: true,
children: [
{
path: '/redirect/:path(.*)',
component: () => import('@/views/redirect/index.vue')
}
]
},
{
path: '/',
redirect: '/dashboard',
hidden: true
},
{
path: '/login',
name: 'Login',
component: Login,
hidden: true
},
{
path: '/dashboard',
component: Layout,
redirect: '/dashboard/index',
isFirst: true,
children: [
{
path: 'index',
name: 'Dashboard',
component: () => import('@/views/dashboard/index.vue'),
meta: {
title: '首页',
icon: 'el-icon-location'
}
}
]
}
];
// 动态路由
export const asyncRoutes = [
{
path: '/form',
component: Layout,
redirect: '/form/index',
isFirst: true,
children: [
{
path: 'index',
name: 'Form',
component: () => import('@/views/form/index.vue'),
meta: {
title: '表单',
role: 'form',
icon: 'el-icon-location'
}
}
]
},
{
path: '/editor',
component: Layout,
redirect: '/editor/index',
meta: {
role: 'editors',
title: '总富文本',
icon: 'el-icon-location'
},
children: [
{
path: 'index',
name: 'Editor',
component: () => import('@/views/editor/index.vue'),
meta: {
title: '富文本',
role: 'editor',
icon: 'el-icon-location'
}
},
{
path: 'two',
name: 'Two',
redirect: '/editor/two/three',
component: () => import('@/views/editor/two.vue'),
meta: {
title: '二级导航',
role: 'two',
icon: 'el-icon-location'
},
children: [
{
path: 'three',
name: 'Three',
component: () => import('@/views/editor/three.vue'),
meta: {
title: '三级导航',
role: 'three',
icon: 'el-icon-location'
}
},
{
path: 'four',
name: 'Four',
component: () => import('@/views/editor/four.vue'),
meta: {
title: '三级导航2',
role: 'four',
icon: 'el-icon-location'
}
}
]
}
]
},
{
path: '/tree',
component: Layout,
redirect: '/tree/index',
isFirst: true,
children: [
{
path: 'index',
name: 'Tree',
component: () => import('@/views/tree/index.vue'),
meta: {
title: '树状图',
role: 'tree',
icon: 'el-icon-location'
}
}
]
},
{
path: '/excel',
component: Layout,
redirect: '/excel/index',
isFirst: true,
children: [
{
path: 'index',
name: 'Excel',
component: () => import('@/views/excel/index.vue'),
meta: {
title: '导入导出',
role: 'excel',
icon: 'el-icon-location'
}
}
]
}
];
// 出错跳转的路由
export const error = [
// 404
{
path: '/404',
component: () => import('@/views/error/index.vue'),
hidden: true
},
{
path: '*',
redirect: '/404',
hidden: true
}
];
const createRouter = () =>
new VueRouter({
scrollBehavior: () => ({
x: 0,
y: 0
}),
routes: constantRoutes
});
const router = createRouter();
// 刷新路由
export function resetRouter () {
const newRouter = createRouter();
(router as any).matcher = (newRouter as any).matcher;
}
export default router;
参考网上资料进行封装修改，具体需求可根据项目修改
