I am new to Vuejs. I try to trigger the transition, every time the Homepage router link is clicked by user. I read some of documentation of Passing Props to Route Components enter link description here, and still cannot get it work. I tested the transition is working. But it seems like the loaded boolean did not passed to my component correctly.
Router index.js
{
path: '/',
name: 'Home',
component: Homepage,
props: { loaded: true }
},
Homepage component:
<template>
<transition name='fade'>
<div class="rgba-blue-grey-strong container" v-show="loaded">
<p>Text with transition Every time user access Homepage component</p>
</div>
</transition>
</template>
<script>
export default {
name: "Homepage",
props:['loaded'],
data(){
return{
loaded: false,
}
}
}
You have loaded defined in both props and data object. Remove the one in your data object and it'll be fine.
<script>
export default {
name: "Homepage",
props:['loaded'],
data(){
return {
}
}
}
</script>

I need to render a different layout for the same route for a specific URI with different components depending on the user being on mobile or in desktop.
I would like to avoid having route path checks in the PageCommon(layout component) to keep it clean.
The app has a main component taking care of the layout, it has different router-views where we load the different components for each page URI. This would be a normal route for that.
{
path: '',
component: PageCommon,
children: [
{
path: '',
name: 'Home',
components: {
default: Home,
header: Header,
'main-menu': MainMenu,
'page-content': PageContent,
footer: Footer,
'content-footer': ContentFooter
}
},
I can't change the route components property once the component is loaded so I tried to make a wrapper and pass the components dynamically.
{
path: 'my-view',
name: 'My_View',
component: () => import('#/components/MyView/ViewWrapper')
},
In /components/MyView/ViewWrapper'
<page-common v-if="isMobile">
<my-mobile-view is="default"></my-mobile-view>
<main-menu is="main-menu"></main-menu>
</page-common>
<page-common v-else>
<my-desktop-view is="default"></my-desktop-view>
<header is="header"></header>
<main-menu is="main-menu"></main-menu>
<footer is="footer"></footer>
</page-common>
</template>
I would expect that the components passed inside page-common block would be substituted on the appropriate , but is not how it works, and Vue just loads page-common component with empty router-views.
Is there any approach for this?
Note that I already tried using :is property for loading different components, but the problem then is on how to tell the parent to use this or that component for this page. This is the code for that:
<template>
<component :is="myView"></component>
</template>
<script>
import DesktopView from "#/components/MyView/DesktopView";
import MobileView from "#/components/MyView/MobileView";
export default {
name: 'MyView',
components: {
DesktopView,
MobileView,
},
data(){
return {
myView: null,
isMobile: this.detectMobile()
}
},
methods : {
getViewComponent() {
return this.isMobile ? 'mobile-view' : 'desktop-view';
}
},
created() {
this.myView = this.getViewComponent();
}
}
</script>
I could use this approach for each of the PageCommon router views, creating a component for each that does the above, but it looks like a very bad solution.
A computed method is all you need.
You should have this top level Logic in App.vue and the <router-view> should be placed in both DesktopView and MobileView.
// App.vue
<template>
<component :is="myView"></component>
</template>
<script>
import DesktopView from "#/components/MyView/DesktopView";
import MobileView from "#/components/MyView/MobileView";
export default {
name: 'MyView',
components: {
DesktopView,
MobileView,
},
computed: {
myView() {
return this.detectMobile() ? 'mobile-view' : 'desktop-view';
}
}
}
</script>
You may also want to consider code splitting by setting up Dynamic Components for those layouts since Mobile will load Desktop View because it is compiled into final build, register them globally as dynamic imports instead if importing them in MyView and then delete components also after doing the following instead, this way only the one that is needed will be downloaded saving mobile users their bandwidth:
// main.js
import LoadingDesktopComponent from '#/components/LoadingDesktopComponent '
Vue.componenet('desktop-view', () => ({
component: import('#/components/MyView/DesktopView'),
loading: LoadingDesktopComponent // Displayed while loading the Desktop View
})
// LoadingDesktopComponent .vue
<template>
<div>
Optimizing for Desktop, Please wait.
</div>
</template>
<script>
export default {
name: 'loading-component'
}
</script>
Routing logic will only be processed when <router-view> is available,this means you can delay the presentation of Vue Router, for example you can have :is show a splash screen like a loading screen on any URI before displaying a component in :is that contains <router-view>, only than at that point will the URI be processed to display the relevant content.
Im using Vue Router. In my code I used to have:
<div v-bind:is="page.component_name" v-bind:page="page"></div>
Which worked, and the page data was passed to the component. But how do I do the same with a router-view? This doesn't seem to work:
<router-view v-bind:page="page"></router-view>
js:
var vm = new Vue({
...,
router : new VueRouter({
routes : [
{ path: '/foo', component: { template: '<div>foo</div>', created:function(){alert(1);} } },
//{ path: '/bar', component: { template: '<div>bar</div>', created:function(){alert(2);} } },
{ path: '/bar', component: Vue.component("ti-page-report") }
]
}),
...
});
vue-router has a dedicated page in docs on how to pass props to router-view.
Passing Props to Route Components
Example snippet from docs:
const router = new VueRouter({
routes: [
{ path: '/user/:id', component: User, props: true },
// for routes with named views, you have to define the `props` option for each named view:
{
path: '/user/:id',
components: { default: User, sidebar: Sidebar },
props: { default: true, sidebar: false }
}
]
})
If you are looking for simplified usage, props can still be passed the same way they are passed to any component. But component that is used for rendering the route (the one that is specified in route definition) should expect to receive the props.
Here is simple usage example of passing props to router-view:
I personally decided to use provide/inject feature: preserving reactivity with minimal overhead.
The component ("ti-page-report") that needs to access the props being sent just needs to add it:
<template>
<div>
<h1>Now you can access page: {{ page }}</h1>
</div>
</template>
export default {
name: "TiPageReport",
props: ['page'], // can now be accessed with this.page
...
};
See https://v2.vuejs.org/v2/guide/components-props.html for how to use props properly.
Im trying to install Vue.js with the router and im running into some view issues. I have a router.js with child routes. I want to use this method for simple breadcrumbs and generate a clear overview so i know which route belongs where.
Opening each route works like a charm, everything shows up. When i open /apps I get a nice view from my Apps.vue that displays App overview</h1>. But now im opening /apps/app-one and then I see the Apps.vue and AppOne.vue template. How can I prevent that both templates are displayed?
The vue components looks like this:
Router.js
import Router from 'vue-router';
import AppsPage from './components/Apps.vue'
import AppOne from './components/AppOne.vue'
import AppTwo from './components/AppTwo.vue'
export default new Router({
// mode: 'history',
routes: [
{
path: '/apps',
component: AppsPage,
children: [
{
path: '/apps/app-one',
component: AppOne,
},
{
path: '/apps/app-two',
component: AppTwo,
},
]
},
]
});
Apps.vue
<template>
<div id="app-overview">
<h1>App overview</h1>
<router-view></router-view>
</div>
</template>
<script>
export default {
name: 'app_page'
}
</script>
App1.vue
<template>
<div>
<h1>App 1</h1>
</div>
</template>
<script>
export default {
name: 'app_one'
}
</script>
App2.vue
<template>
<div>
<h1>App 2</h1>
</div>
</template>
<script>
export default {
name: 'app_two'
}
</script>
Having your routes in a parent-child relationship means that the child component will be rendered inside the parent component (at the <router-view>). This is expected behavior.
If you do not want the parent component to be visible when the child route is active, then the routes should be siblings, not nested:
[
{
path: '/apps',
component: AppsPage,
},
{
path: '/apps/app-one',
component: AppOne,
},
{
path: '/apps/app-two',
component: AppTwo,
},
]
The structure of the routes reflects the way they are rendered on the page.
It's possible and pretty easy too.You can achieve this by followings:
<template>
<div>
<div v-show="isExactActive">
Parent component contents will be here
</div>
<router-view ref="rv"></router-view>
</div>
</template>
<script>
export default {
data() {
return {
isExactActive: true,
}
},
updated() {
this.isExactActive = typeof this.$refs.rv === 'undefined';
},
mounted() {
this.isExactActive = typeof this.$refs.rv === 'undefined';
}
}
</script>
Hope, this will be helpful.
I have navbar blade, component with text and another components with page.
It works like I have component with text in navbar, and another component after navbar. That's three another components. How to change text from for example index.vue in text.vue?
That's what I have:
Text.vue:
<template>
<p class="title">{{msg}}</p>
</template>
<script>
export default {
props: [
'msg',
],
data() {
return {
}
},
mounted() {
},
methods: {
}
}
</script>
Component in navbar.blade.php:
<navbar-title></navbar-title>
And I try to change it in index.vue, that should work when we are on this page:
data() {
return {
msg: 'text',
}
But it doesn't work. How to do it correctly?
EDIT:
Vue.component('title', require('./components/Title.vue'));
To pass the message variable from your index.vue through navbar.vue to title.vue each needs to pass the property to the child and each child must pass the property on again all throughout the tree.
Something like this should work for your case: <title :msg="msg"></title>
I've am new at Vue and i've got a problem with unaccessible. I've got two files.
1st is App.vue where is defined <router-view>
<script>
export default {
name: 'app',
data(){
return{
info: false,
}
},
beforeMount(){
example...
this.info= true
this.$router.push('/main'); //where in router-view visible is component Main.vue
}
}
</script>
2nd is component Main.vue which is clear:
<script>
export default{
name: 'main',
data(){
return{
}
},
beforeMount(){
//what i want to do:
console.log(App.data().info) //here should be visible true in console log
}
}
i would like to have accessible in 2nd file the property from file number one. How to do it properly? Thank you in advance
Two options that i can think of :
Passing Props to Route Components
Source : link
In your router :
import main from './main.vue'
const router = new VueRouter({
routes: [
{ path: '/main/:id', component: main }
]
})
In your Main.vue
Access to the variable : this.$route.params.id
Save the data in state manager and get access to him through the state in another component Vuex
Every component instance has its own isolated scope. As stated here: https://v2.vuejs.org/v2/guide/components.html#Passing-Data-with-Props
you cannot (and should not) directly reference parent data in a child component’s template. Data can be passed down to child components using props.
