I am kinda new in vue.js
I have a laravel app with vue.js. When hp is loading script also loading all elements are initialised (owl carousel, rev slider etc), but when i click other route contact or about and come back to hp the sliders or other related to js doesnt load .
routes.js
import VueRouter from 'vue-router';
import Home from './components/views/Home.vue';
import About from './components/views/About.vue';
import Contact from './components/views/Contact.vue';
let routes = [
{ path: '/', component: Home },
{ path: '/about', component: About },
{ path: '/contact', component: Contact },
{ path: '/notes', component: Notes }
];
export default new VueRouter({
routes,
linkActiveClass: 'active'
});
and app.js
import router from './routes';
import './components';
const app = new Vue({
el: '#app',
router
});
Is there a way to run the functions to load carousels etc each time i change view ?
On mounted trigger you can add your custom js for each component
<script>
export default {
mounted () {
}
}
</script>
if anyone stumbles upon this and still looking for a way to do it, this is how I managed to do this. wrap the <route-view/> in a <transition> which you can control with css and call a method on enter which calls the function you want.
this will call the function as soon as the component is loaded in the DOM on every route change
<transition name="slide" v-on:enter="reInitJS">
<router-view></router-view>
</transition>
<script>
//import the wanted function
import {init} from './main';
export default {
name: 'App',
methods: {
reInitJS(){
//call the function
init();
}
}
}
</script>

I need to create a component in Vue JS dynamically on click and then route to that component. I am using Vue 3. Everything needs to happen in one click.
My code looks something like this
methods:{
routerClick(value){
console.log("number is "+value)
this.$router.push({path:'New', name:'New', component: ()=>Vue.component('New')})
}
},
I do not need to move a component that is already created. I want to create a component inside this method and then route to the component using this router. Please, any suggestions will be highly appreciated.
Below is a simplistic solution that works (I'm not an expert in Vue 3).
The main point is to use addRoute before pushing to it, because you cannot specify the route component when pushing to a route.
Here is the codesandbox with the working solution.
<template>
<router-link to="/">Home</router-link>
<button #click="createComponent">Create Component</button>
<router-view></router-view>
</template>
<script>
import { getCurrentInstance } from "vue";
import { useRouter } from "vue-router";
export default {
name: "App",
setup() {
const app = getCurrentInstance().appContext.app;
const router = useRouter();
const createComponent = () => {
// Check if the component has been alreadey registered
if (!app.component("NewComponent")) {
app.component("NewComponent", {
name: "NewComponent",
template: `<div>This is a new component</div>`
});
}
const newComponent = app.component("NewComponent");
// Adding a new route to the new component
router.addRoute({ path: "/new", component: newComponent });
router.push("/new");
};
return {
createComponent,
};
},
};
</script>
So i am using Vuex and have a simple mutation set up which console logs a message. I have two routes setup, the /which goes to my HelloWorld component and /another which goes to the AnotherWorld component. I am trying to setup a watch on my route so that when the route changes, it fires off the mutation. I did setup a watch but it doesn't seem to be firing off my mutation.
Check out this CodeSandbox.
Check out the code snippet:-
This is My Vuex Store:-
mutations: {
routeChange() {
console.log("Helloooo!!!!!");
}
This is My Hello World Component:-
<template>
<div>
<h1>Hello World!!!</h1>
<router-link to="/another">Switch</router-link>
</div>
</template>
<script>
export default {
name: "HelloWorld",
watch: {
$route(to, from) {
this.$store.commit("routeChange");
}
}
};
</script>
This is my AnotherWorld Component:-
<template>
<div>
<h1>Another World</h1>
<router-link to="/">Back</router-link>
</div>
</template>
<script>
export default {};
</script>
As you can see i have setup the watch but it doesn't seem to be doing anything. Any help will be appreciated. Thank you.
I would instead use a global after hook navigation guard in your router.
For example
// router.js
import Vue from 'vue'
import VueRouter from 'vue-router'
import store from '../store'
Vue.use(VueRouter)
const router = new VueRouter({
routes: [...]
})
router.afterEach(() => {
store.commit('routeChange')
})
export default router
If you only want to catch route navigation away from certain components, you can use the beforeRouteLeave in-component guard
// MyComponent.vue
export default {
name: 'MyComponent',
beforeRouteLeave (to, from, next) {
this.$store.commit('routeChange')
next()
}
}
If you put watchers in individual route components they will never fire because $route is set before these components instantiation and is then changed after these components destruction.
You either need to put the watch in App.vue (parent of <router-view>), or commit from one of the vue-router guards (https://router.vuejs.org/guide/advanced/navigation-guards.html)
I am very new to the Vue framework, as well as Javascript, but am currently building a site using Vue and I want to have some links at the top of my site that the user can navigate to. I have tried using the Vue Router (https://router.vuejs.org/guide/#javascript) in order to make these links. At this point, I just want to make a little 'About Us' section that the user can navigate to. But, despite the URL changing accordingly to 'localhost:8080/#/about_us', the Vue component that I have associated with the link will not show up.
I have structured my code in the main.js as such:
import Vue from 'vue'
import VueRouter from 'vue-router'
import App from './App.vue'
Vue.config.productionTip = false
export const eventBus = new Vue();
Vue.use(VueRouter);
const AboutUs = {template: '<div>about_us</div>'};
const route = [{path:'/about_us', component: AboutUs}];
const router= new VueRouter({route});
new Vue({
render: h => h(App),
router
}).$mount('#app')
And then I have my app.vue designed as (note: I reduced much of the code to its essentials for brevity):
import AboutUs from './components/AboutUs.vue'
import { eventBus } from './main.js'
export default {
data(){
return {
films: []
}
},
components: {
"about-us": AboutUs
},
mounted(){
fetch('https://ghibliapi.herokuapp.com/films')
.then(res => res.json())
.then(films => this.films = films)
.catch(error=> console.log(error))
}
}
</script>
body {
background-color: deepskyblue;
}
<h1>Ghibli Fandom Extravaganza</h1>
<nav>
<li><router-link to="/about_us">About us </router-link></li>
<router-view></router-view>
</nav>
<p>List of Ghibli Movies: <films-list :films="films"/></p>
<film-detail />
At this point, my AboutUs component is only a very basic Vue that shows some information about the site in some simple HTML tags. But although the link is active and does work, the information from the Vue is not displayed, while the other Vue components continue to show, which indicates that maybe they are not connected? I have tried to follow the tutorial in the Vue Router site, but I don't think that I understand the mechanics of how the code actually works. Can anybody recommend me any corrections?
UPDATE:
Here is the code to my AboutUs.vue
<template>
<div>
<h1>This site is for examining the movies of Studio Ghibli</h1>
</div>
</template>
<script>
export default {
name: 'about-us'
}
</script>
<style scoped>
</style>
I think there is no need to import 'aboutus' component. You can just write like this <router-link to="about_us">About us </router-link>
and in the main.js declare the route like this
const route = [{path:'/about_us',name:'about_us', component: () => import("path to about us file")}];
The code samples you provided are a bit confusing, you should simply pass an imported view straight in to the component property of a router entry.
Where you have done:
const AboutUs = {template: '<div>about_us</div>'};
Replace that line with:
import AboutUs from './components/AboutUs.vue'
I can't figure out from your sample, when and what the relevance of components: {"about-us": AboutUs }, it is not needed.
Here is a sample of my setup:
router.js
import Vue from 'vue'
import VueRouter from 'vue-router'
Vue.use(VueRouter)
const routes = [
{
path: '/',
name: 'index',
component: () => import('../components/views/welcome')
},
{
path: '/about-us',
name: 'about-us',
component: () => import('../components/views/about-us')
}
]
const router = new VueRouter({
mode: 'history',
routes
})
export default router
main.js
import Vue from 'vue'
import App from './App.vue'
import router from './router'
Vue.config.productionTip = false
new Vue({
router,
render: h => h(App)
}).$mount('#app')
App.vue
<template>
<v-app v-cloak>
<router-link :to="{ name: 'index' }">Welcome</router-link>
<router-link :to="{ name: 'about-us' }">About Us</router-link>
<router-view></router-view>
</v-app>
</template>
<script>
export default {
name: 'App'
}
</script>
components/views/about-us.vue
<template>
<div>This is the About Us page!</div>
</template>
<script>
export default {
name: 'about-us'
}
</script>
This sample uses History Mode
Other things to note
When routing, mounted is unreliable, instead you should place any fetch logic into it's own method when calling any :
methods: {
fetch () {
// https://github.com/axios/axios
axios.get('https://ghibliapi.herokuapp.com/films').then( ... )
}
}
Call this.fetch method in both beforeRouteUpdate and beforeRouteEnter instead of mounted, you can't even rely on created when it comes to views handled by vue-router.
Axios is suggested instead of native fetch because axios provides more functionality, features and browser compatibility.
In about-us.vue you add these Navigation Guards like so:
<template>
<div>This is the About Us page!</div>
</template>
<script>
export default {
name: 'about-us'
methods: {
fetch () {
axios.get('https://ghibliapi.herokuapp.com/films').then( ... )
}
}
// Will fire if you are already on the view but a parameter changes (dynamic routing)
beforeRouteUpdate(to, from, next) {
this.fetch()
next()
},
// Will fire when you enter the view
beforeRouteEnter(to, from, next) {
this.fetch()
next()
},
}
</script>
Both should be added, understand that they won't fire at the same time, only one of them will execute fetch once when relevant.
This will resolve any issues you would otherwise encounter with Dynamic Routing should you ever use them.

How Can I pass router to my child component.
I have this as my router
import Vue from 'vue'
import VueRouter from 'vue-router'
Vue.use(VueRouter)
export default function () {
const Router = new VueRouter({
mode: 'history',
routes : [
{
path: '/',
beforeEnter: ifAuthenticated,
component: () => {
return import('./../container/Index.vue')
}
},
{
path: '/login',
beforeEnter: ifNotAuthenticated,
component: () => {
return import('./../container/logn.vue')
}
}
],
})
return Router
}
Now my "/" (index.vue) route have a component Navbar and the Navbar have a logout button which logs out the user and redirect them to login page
Consider this to be my index.vue (with what I have done)
<template>
<q-layout>
<Navbar :thisInfo="routerAndStore"/>
</q-layout>
</template>
<script>
import Navbar from "./../components/navbar.vue";
export default {
name: "PageIndex",
components: {
Navbar
},
data() {
return {
routerAndStore: this
};
}
};
</script>
And then in my navbar.vue I have done something like this
<template>
<div class="nav-pages-main">
<a #click="logoutUser">
<h5>Logout</h5>
</a>
</div>
</template>
<script>
export default {
name: "navbar",
methods: {
logoutUser: () => {
return this.thisInfo.$store.dispatch("GOOGLE_PROFILE_LOGOUT").then(() => {
this.$router.push("/login");
});
}
},
props: {
thisInfo: {
type: Object
}
}
};
</script>
but this doesn't seem to be working (this is coming out to be undefined), So if someone can help me figure out how we can pass this to our child component
Please refer to Vue-Router official documentation here
Basically, in their use case, the main component (index.vue) take a router as argument and provide <router-view> in its template as placeholder for component that would be rendered based on the current route.
In your code, I see that you use it the other way around using router to render the main component.
routes : [
{
path: '/',
beforeEnter: ifAuthenticated,
component: () => {
return import('./../container/Index.vue')
}
},
...
]
Could you try it again using the right way described in the documentation and tell me the result?
Edit: According to the App.vue that you posted (assuming it's the app entry point) then you should provide router to the App component.
<template>
<div id="q-app"> <router-view/> </div>
</template>
<script>
import router from '/path/to/your/router';
export default { name: "App", router };
</script>
<style>
</style>
The full code for this can be found at Vue-Router example
I'm trying to setup Vue router for the first time and I'm running into trouble.
router/index.js
import Vue from 'vue'
import Router from 'vue-router'
import Services from '../components/Services'
import App from '../app'
Vue.use(Router)
export default new Router({

component: App
},
{

name: 'Services',
component: Services
}
]
})
app.vue
<template>
<div id='app'>
<Navigation></Navigation>
<div class="Site-content">

</div>
<Footer></Footer>
</div>
</template>
<script>
import Services from "../javascript/components/Services";
import Footer from "../javascript/components/Footer";
import Navigation from "../javascript/components/Navigation";
export default {
components: {
Footer,
Navigation,
Services
},
data: function () {
return {
message: "Welcome to Ping Party From Vue!"
}
}
}
</script>
Navigation.vue
<template>
<div id="navigation">
<nav v-bind:class="active" v-on:click>
Home
Projects
<router-link to="/services">Services</router-link>

</div>
</template>
<script>
import Services from './Services'
export default {
data () {
return { active: 'home' }
},
methods: {
makeActive: function(item) {
this.active = item;
}
}
}
</script>
That vue-router option is not working in my navigation. It shows up on the page but it's not clickable and I'm getting this error in the console.

Make sure to register your router with your Vue instance.
So in your
import router from './router'
new Vue({
el: '#some-element'
router, // This line is important
render: h => h(App)
})
