如何使用vue.js和vue路由器实现当前路由子节点的子菜单 [英] How to implement sub menu of the current route's children with vue.js and vue router
问题描述
我正在尝试在我的Vue应用程序上进行导航，使主菜单顶部填充所有根级别路径，如果路径有任何子级则使用侧边菜单。像这样：
我目前的设计主要有使用下面的路由器视图在顶部导航路由链接。我已经能够使侧边菜单工作，所以当我选择Travellers并正确更新组件/内容时它才显示出来。但是我无法正确路由，当我点击子菜单中的一个链接时，它不会附加到当前路径。因此，当我在 localhost / Traveler 时单击查看并单击查看时，网址将更改为 localhost / View / ，而不是本地主机/旅行者/视图即可。当我在子菜单中选择某些内容时，顶部菜单上的选择也会被取消选择。
我无法通过 localhost / Traveler / View 之类的内容访问这些页面 localhost / View
我开始重读有关
我只是不确定如何访问这些属性。
更新1/29/2019：
我发现你需要做的就是路径是使用 $ Route.matched [0] .path 你可以在这里了解更多。
现在我已经能够将菜单简化为这样的SFC：
< template>
< nav id =sidebar>
< div class =sidebar-header>
< h3> Bootstrap边栏< / h3>
< / div> $ router $。$ b< ul class = .matched [0]。路径）>
< li v-for =child in route.children>
< a class =nav-item：key =index>
< router-link：to =route.path +'/'+ child.pathexact-active-class =active>
< icon：icon =route.iconclass =mr-2/>< span> {{child.name}}< / span>
< / router-link>
< / a>
< / li>
< / ul>
< / nav>
< / template>
< script>
导出默认{
data（）{
return {
}
}
}
< / script>
不包括CSS。
编辑：我现在把它作为我的首选答案，因为它允许我通过引用组件在任何地方使用侧边菜单。我不需要传递任何东西，它应在任何地方工作。我确实喜欢digitaldrifter的回答，因为他有一个小提琴。
I'm trying to have the navigation on my Vue app to have a main menu up top populated by all the root level routes, and a side menu if the route has any children. Like so:
The current Design I have has the main navigation with routing links on the top with the router-view below. I have been able to get the side menu working so it it only shows up when I choose Travellers and updates the components/content correctly. However I'm having trouble routing things correctly, when I click on one of the links in the sub menu it does not append to the current path. So when I click on View when I'm in localhost/Traveler and click View the url changes to localhost/View/ instead of localhost/Traveler/View. Also the selection on the top menu gets unselected when I choose something in the child menu.
And I cannot get to the pages via something like localhost/Traveler/View only localhost/View
I started rereading the documentation on nested routes as I began making this post and I think I realized that I should be creating an new router at each level which is not something I have done in my code below.
I'm also not sure how to access the children of the current route. I've tried to display them like so:
<h2>Route: {{ $route.name }}</h2>
<ul id="example-1">
<li v-for="child in $route.children">
{{ child.name }}
</li>
</ul>
But I get nothing. Should they be passed as Params or something? Or are the not that easily accessible?
Any advice or help will be greatly appreciated.
Root
Contains top Menu-Nav with router links and router-view below.
<template>
<div id="app" class="container-fluid">
<div class="row">
<div style="width:100%">
<nav-menu params="route: route"></nav-menu>
</div>
</div>
<div class="row">
<div>
<router-view></router-view>
</div>
</div>
</div>
</template>
<script>
import NavMenu from './nav-menu'
export default {
components: {
'nav-menu': NavMenu
},
data() {
return {}

Top Nav-Menu
Gets populated with the routes
<template>
<nav class="site-header sticky-top py-1">

<a class="nav-item" v-for="(route, index) in routes" :key="index">
<router-link :to="{path: route.path, params: { idk: 1 }}" exact-active-class="active">
<icon :icon="route.icon" class="mr-2" /><span>{{ route.display }}</span>
</router-link>
</a>
</div>
</nav>
</template>
<script>
import { routes } from '../router/routes'

Traveler Page/View
Currently the Traveller Page which has a side bar menu and another router view for the content:

<script>
import TravelerMenu from './traveler-menu'
export default {
components: {
'traveler-menu': TravelerMenu
},
data() {
return {}
}
}
</script>
Side Bar/ Traveler Menu
<template>
<nav id="sidebar">
<div class="sidebar-header">
<h3>Route's Children:</h3>
</div>
<ul class="list-unstyled components">
<li>
<a class="nav-item" v-for="(route, index) in travelerroutes" :key="index">
<router-link :to="{path: route.path, params: { idk: 1 }}" exact-active-class="active">
<icon :icon="route.icon" class="mr-2" /><span>{{ route.display }}</span>

methods: {
toggleCollapsed: function (event) {
this.collapsed = !this.collapsed

Let me know if you you need anymore details, context or code.
I made some modifications to DigitalDrifter's answer where I find the children using the template syntax. I'm pretty sure my answer will stop working after another level of children so I'm going to say DigitalDrifter still has a better answer.
Also I'm not sure how preserve the sub menues route (localhost/Traveller) so it isn't searching the children of (locathost/Traveller/View) when I click on something like view. Right now I'm doing it in kind of a janky way:
v-for="(route, index) in $router.options.routes.filter(x=>x.path==$route.path||$route.path.includes(x.path))"
Thet full SFC without styling is here:
<template>
<nav id="sidebar">
<div class="sidebar-header">
<h3>Bootstrap Sidebar</h3>
</div>
<ul class="list-unstyled components" v-for="(route, index) in $router.options.routes.filter(x=>x.path==$route.path||$route.path.includes(x.path))">
<li v-for="child in route.children">
<a class="nav-item" :key="index">
<router-link :to="{path: route.path+'/'+child.path}" exact-active-class="active">
<icon :icon="route.icon" class="mr-2" /><span>{{ child.path }}</span>
</router-link>
</a>
</li>
</ul>
</nav>
</template>
<script>
export default {
data() {
return {
}
},
methods: {
}
}
</script>
Edit: I know vue has the data I want associated with the routers views as shown here,
I'm just not sure how to access those properties.
Update 1/29/2019:
I figured out that all you need to do to get the path is by using $Route.matched[0].path you can learn more here.
Now I have been able to simplify the menu into an SFC like this:
<template>
<nav id="sidebar">
<div class="sidebar-header">
<h3>Bootstrap Sidebar</h3>
</div>
<ul class="list-unstyled components" v-for="(route, index) in $router.options.routes.filter(x=>x.path==$route.matched[0].path)">
<li v-for="child in route.children">
<a class="nav-item" :key="index">
<router-link :to="route.path+'/'+child.path" exact-active-class="active">
<icon :icon="route.icon" class="mr-2" /><span>{{ child.name }}</span>
</router-link>
</a>
</li>
</ul>
</nav>
</template>
<script>
export default {
data() {
return {
}
}
}
</script>
CSS not included.
Edit: I now made this my preferred answer because it allows me to use the side menu anywhere by just referencing the component. I don't need to pass anything into it and it should work anywhere. I do like digitaldrifter's answer though because he has a fiddle for it.
