前提
實驗項目中，在一個 /list/user 列表中，當點擊某一條時，需要跳轉到 /detail/userId/user 詳情下，展示詳情信息。
router.js
const routes = [
{
path: '/ue/matter/list',
name: 'list',
component: List,
children: [
{ path: 'user', name: 'list-user', component: ListUser },
],
props: true
},
{
path: '/ue/matter/detail/:userId',
name: 'detail',
component: Detail,
children: [
{ path: 'user', name: 'detail-user', component: DetailUser },
],
props: true
}
]
ListUser 組件中，採用編程式導航的方式跳轉，寫法如下：
this.$router.push({name:detail-user, path:`/ue/matter/detail/user/${userid}/user}`)；
或者如下
this.$router.push({name: detail-user});
結果
組件內容確實更換了，但瀏覽器上的地址欄錯了
實驗
看官方文檔說，path+params地方式會被忽略，所以將router.push中用到的鍵path、params、name、query分別組合做了一個頁面，來測試哪種會不可以。

const User = { template: "<div>User {{$route.params.userId}}</div>" }
const Many = { template: "<div>Many name+params</div>" }
const Too = { template: "<div>Too params + query</div>" }
const router = new VueRouter({
routes: [
{
path: "/home",
component: Home
},
{
name: "foo",
path: "/foo",
component: Foo
},
{
path: "/bar",
component: Bar
},
{
name: "user",
path: "/user/:userId",
component: User
},
{
path: "/many",
name: "many",
component: Many
},
{
path: "/too/:userId",
component: Too

]
})
new Vue({
el: '#app',
router
})

結論
結果是：除了path+params之外，params+query也不可以，因爲沒有告知路徑信息
那對於上面涉及二級跳轉，那寫name + path的方式，我理解的是path需要拼接，所以給了name就會找不到路徑。我之後的修改是，只傳給push一個字符串路徑。
this.$router.push(`/ue/matter/detail/user/${userid}/user`)
