How can I run slider in vue component? - vue.js

My view like this :
#foreach($leagues as $league)
<a #click="$refs.leagues.changeLeague({{ $league->id }})">
{{ $league->name }}
</a>
#endforeach
...
<top-league class="slick" league-id="{{ $league_id }}" ref="leagues"></top-league>
My top league component vue like this :
<template>
<div class="row">
<div class="col-md-3" v-for="item in items">
<div class="panel panel-default">
<div class="panel-image">
<a :href="baseUrl+'/leagues/'+item.id+'/'+item.name"
:style="{backgroundImage: 'url(' + baseUrl + '/img/leagues/'+item.photo+ ')'}">
</a>
</div>
</div>
</div>
</div>
</template>
<script>
...
export default {
...
props: ['leagueId'],
created() {
$('.slick').slick({slidesToShow: 3, infinite: false});
this.getTopLeague([{league_id: this.leagueId}]) // this is ajax if load first
},
computed: {
...mapGetters([
'getListLeague'
]),
items() {
const n = ['getListLeague']
return this[n[0]] // this is response ajax // exist 5 league
}
},
methods: {
...mapActions([
'getTopLeague'
]),
changeLeague(leagueId) {
this.getTopLeague([{league_id: leagueId}]) // this is ajax if a link clicked
}
}
}
</script>
When loaded the first time, there are 5 items of data displayed in the form of sliders. I tried putting this code : $('.slick').slick({slidesToShow: 3, infinite: false}); in created, but there was an error
If the code executed, there exist error like this :
[Vue warn]: Error in created hook: "TypeError: $(...).slick is not a
function"
How can I solve it?

Ok, try this.
<template>
<div ref="slick">
<div class="row">
<div class="col-md-3" v-for="item in items">
<div class="panel panel-default">
<div class="panel-image">
<a :href="baseUrl+'/leagues/'+item.id+'/'+item.name"
:style="{backgroundImage: 'url(' + baseUrl + '/img/leagues/'+item.photo+ ')'}">
</a>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
...
export default {
...
props: ['leagueId'],
mounted() {
$(this.$el).slick({slidesToShow: 3, infinite: false});
this.getTopLeague([{league_id: this.leagueId}]) // this is ajax if load first
},
computed: {
...mapGetters([
'getListLeague'
]),
items() {
const n = ['getListLeague']
return this[n[0]] // this is response ajax // exist 5 league
}
},
methods: {
...mapActions([
'getTopLeague'
]),
changeLeague(leagueId) {
this.getTopLeague([{league_id: leagueId}]) // this is ajax if a link clicked
}
}
}
</script>

can't display vuejs data property inside vue template

I'm trying to use eventbus to send data from component A:
<template>
<div v-for="(user, index) in users" :key="index" class="col-lg-6">
<div class="card card-primary card-outline">
<div class="card-body d-flex">
<h1 class="mr-auto">{{ user.name }}</h1>
Afficher
</div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
users: {},
}
},
methods: {
envoyerDetails($data){
Fire.$emit('envoyer_details_projet', $data);
this.$router.push('details-projet');
},
loadUser() {
if(this.$gate.isAdmin()){
axios.get("api/user").then(({ data }) => (this.users = data.data));
}
}
},
mounted() {
this.loadUser()
}
}
</script>
In component B, i receive the data and i want to display it inside the template this way:
<template>
<div class="right_col text-center" role="main">
<h5><b>name: {{ user.name }}</b> </h5>
</div>
</template>
export default {
data() {
return {
user: {},
}
},
methods: {
afficherDetails (args) {
this.user = args;
console.log(this.user.name);
}
},
mounted() {
Fire.$on('envoyer_details_projet', this.afficheDetails);
}
}
The data is not displayed in the template but it is displayed in the console. What am i missing?
Maybe when you emit the event envoyer_details_projet in component A, but component B is not mounted yet so that it can't receive the data.

Vue : params value don't change in created method

I have this link to another component with params :
<div class="dropdown-menu bg-light" aria-labelledby="navbarDropdown">
<div v-for="category in categories" :key="category.id">
<div v-if="lang=='ku'"><li><a class="dropdown-item font-weight-bold py-2" href="#" ><router-link :to="{name:'category',params:{id:category.id}}">{{category.catagory_ku}}</router-link></a></li></div>
<div v-else><li><a class="dropdown-item font-weight-bold py-2" href="#" ><router-link :to="{name:'category',params:{id:category.id}}">{{category.catagory_ar}}</router-link></a></li></div>
</div>
</div>
the category component like this :
<template>
<div style="margin-top:132px">
Categories {{id}}
</div>
</template>
<script>
export default {
data(){
return {
id :''
}
},
created(){
this.id=this.$route.params.id
}
}
</script>
when i pressed the route link the id value changed in url but in the page view it just take first id value I clicked and not be changed after I clicked another same link by different id value
Try to define the id as computed property :
<template>
<div style="margin-top:132px">
Categories {{id}}
</div>
</template>
<script>
export default {
computed:{
id(){
return this.$route.params.id
}
}
}
</script>
this should be in the mounted hook
created(){
this.id=this.$route.params.id
}
// replace with
mounted(){
this.id = this.$route.params.id
}
also if you wanna perform some extra actions related to the id changes, you can watch the route
<template>
<div style="margin-top:132px">
Categories {{ id }}
</div>
</template>
<script>
export default {
data() {
return {
id: ''
}
},
mounted() {
this.id = this.$route.params.id
},
watch: {
$route(to) {
this.id = to.params.id
// do other logics here
}
}
</script>

Vue Eventbus: handler.apply is not a function

I want to reload one of my components when an other component changes (for example I send a put with axios)
I tried it with eventbus but I got this error:
handler.apply is not a function
In the component where I want to trigger:
EventBus.$emit('compose-reload', Math.random()*100);
Where I want to be triggered:
<template>
<div class="">
<div class="">
<div class="columns">
<div class="column is-one-fifth">
<div class="box">
<Menu></Menu>
</div>
</div>
<div class="column is-four-fifth">
<div class="box">
<router-view :key="key"></router-view>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
import Menu from './includes/Menu'
import EventBus from '../../../event-bus';
export default {
components: {
Menu,
},
data() {
return {
key: null
}
},
mounted(){
EventBus.$on('compose-reload', this.key);
},
created(){
this.key = Math.random()*100
}
}
</script>
EventBus.$on expects a handler function as a second argument but the variable this.key is passed in, hence the error.
You should change this :
mounted(){
EventBus.$on('compose-reload', this.key);
}
To this :
mounted(){
EventBus.$on('compose-reload', key => {
this.key = key;
});
}

Is it possible to sync Vuejs components displayed multiple times on the same page?

I have a web page that displays items. For each items there is a button (vuejs component) which allow user to toggle (add/remove) this item to his collection.
Here is the component:
<template lang="html">
<button type="button" #click="toggle" name="button" class="btn" :class="{'btn-danger': dAdded, 'btn-primary': !dAdded}">{{ dText }}</button>
</template>
<script>
export default {
props: {
added: Boolean,
text: String,
id: Number,
},
data() {
return {
dAdded: this.added,
dText: this.text,
dId: this.id
}
},
watch: {
added: function(newVal, oldVal) { // watch it
this.dAdded = this.added
},
text: function(newVal, oldVal) { // watch it
this.dText = this.text
},
id: function(newVal, oldVal) { // watch it
this.dId = this.id
}
},
methods: {
toggle: function(event) {
axios.post(route('frontend.user.profile.pop.toggle', {
pop_id: this.dId
}))
.then(response => {
this.dText = response.data.message
let success = response.data.success
this.dText = response.data.new_text
if (success) {
this.dAdded = success.attached.length
let cardPop = document.getElementById('card-pop-'+this.dId);
if(cardPop)
cardPop.classList.toggle('owned')
}
})
.catch(e => {
console.log(e)
})
}
}
}
</script>
For each item, the user can also open a modal, loaded by a click on this link:
<a href="#" data-toggle="modal" data-target="#popModal" #click="id = {{$pop->id}}">
<figure>
<img class="card-img-top" src="{{ URL::asset($pop->img_path) }}" alt="Card image cap">
</figure>
</a>
The modal is also a Vuejs component:
<template>
<section id="pop" class="h-100">
<div class="card">
<div class="container-fluid">
<div class="row">
<div class="col-12 col-lg-1 flex-column others d-none d-xl-block">
<div class="row flex-column h-100">
<div v-for="other_pop in pop.other_pops" class="col">
<a :href="route('frontend.pop.collection.detail', {collection: pop.collection.slug, pop: other_pop.slug})">
<img :src="other_pop.img_path" :alt="'{{ other_pop.name }}'" class="img-fluid">
</a>
</div>
<div class="col active order-3">
<img :src="pop.img_path" :alt="pop.name" class="img-fluid">
</div>
</div>
</div>
<div class="col-12 col-lg-6 content text-center">
<div class="row">
<div class="col-12">
<img :src="pop.img_path" :alt="pop.name" class="img-fluid">
</div>
<div class="col-6 text-right">
<toggle-pop :id="pop.id" :added="pop.in_user_collection" :text="pop.in_user_collection ? 'Supprimer' : 'Ajouter'"></toggle-pop>
</div>
<div class="col-6 text-left">
<!-- <btnaddpopwhishlist :pop_id="propid" :added="pop.in_user_whishlist" :text="pop.in_user_whishlist ? 'Supprimer' : 'Ajouter'"></btnaddpopwhishlist> -->
</div>
</div>
</div>
<div class="col-12 col-lg-5 infos">
<div class="header">
<h1 class="h-100">{{ pop.name }}</h1>
</div>
<div class="card yellow">
<div class="card p-0">
<div class="container-fluid">
<div class="row">
<div class="col-3 py-2">
</div>
<div class="col-6 py-2 bg-lightgray">
<h4>Collection:</h4>
<h3>{{ pop.collection ? pop.collection.name : '' }}</h3>
</div>
<div class="col-3 py-2 bg-lightgray text-center">
<a :href="route('frontend.index') + 'collections/' + pop.collection.slug" class="btn-round right white"></a>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</section>
</template>
<script>
export default {
props: {
id: Number
},
data() {
return {
pop: {
collection: {
}
}
}
},
ready: function() {
if (this.propid != -1)
this.fetchData()
},
watch: {
id: function(newVal, oldVal) { // watch it
// console.log('Prop changed: ', newVal, ' | was: ', oldVal)
this.fetchData()
}
},
computed: {
imgSrc: function() {
if (this.pop.img_path)
return 'storage/images/pops/' + this.pop.img_path
else
return ''
}
},
methods: {
fetchData() {
axios.get(route('frontend.api.v1.pops.show', this.id))
.then(response => {
// JSON responses are automatically parsed.
// console.log(response.data.data.collection)
this.pop = response.data.data
})
.catch(e => {
this.errors.push(e)
})
// console.log('fetchData')
}
}
}
</script>
Here is my app.js script :
window.Vue = require('vue');
Vue.component('pop-modal', require('./components/PopModal.vue'));
Vue.component('toggle-pop', require('./components/TogglePop.vue'));
const app = new Vue({
el: '#app',
props: {
id: Number
}
});
I would like to sync the states of the component named toggle-pop, how can I achieve this ? One is rendered by Blade template (laravel) and the other one by pop-modal component. But they are just the same, displayed at different places.
Thanks.
You could pass a state object as a property to the toggle-pop components. They could use this property to store/modify their state. In this way you can have multiple sets of components sharing state.
Your component could become:
<template lang="html">
<button type="button" #click="toggle" name="button" class="btn" :class="{'btn-danger': sstate.added, 'btn-primary': !sstate.added}">{{ sstate.text }}</button>
</template>
<script>
export default {
props: {
sstate: {
type: Object,
default: function() {
return { added: false, text: "", id: -1 };
}
}
},
data() {
return {};
},
methods: {
toggle: function(event) {
axios.post(route('frontend.user.profile.pop.toggle', {
pop_id: this.sstate.id
}))
.then(response => {
this.sstate.text = response.data.message
let success = response.data.success
this.sstate.text = response.data.new_text
if (success) {
this.sstate.ddded = success.attached.length
let cardPop = document.getElementById('card-pop-'+this.sstate.id);
if(cardPop)
cardPop.classList.toggle('owned')
}
})
.catch(e => {
console.log(e)
})
}
};
</script>
Live demo
https://codesandbox.io/s/vq8r33o1w7
If you are 100% sure that all toggle-pop components should always have the same state, you can choose to not define data as a function. Just declare it as an object.
data: {
dAdded: this.added,
dText: this.text,
dId: this.id
}
In https://v2.vuejs.org/v2/guide/components.html#data-Must-Be-a-Function, it mentions
a component’s data option must be a function, so that each instance
can maintain an independent copy of the returned data object
If Vue didn’t have this rule, clicking on one button would affect the
data of all other instances
Since you want to sync the data of all toggle-pop component instances, you don't have to follow the data option must be a function rule.

Why the slider does not work when I click another tab on vue component?

My view like this :
#foreach($leagues as $league)
<a data-toggle="tab" #click="$refs.leagues.changeLeague({{ $league->id }})">
{{ $league->name }}
</a>
#endforeach
...
<div class="tab-pane active">
<top-league class="slick" league-id="{{ $league_id }}" ref="leagues"></top-league>
</div>
My top league component vue like this :
<template>
<div class="row">
<div class="col-md-3" v-for="item in items">
<div class="panel panel-default">
<div class="panel-image">
<a :href="baseUrl+'/leagues/'+item.id+'/'+item.name"
:style="{backgroundImage: 'url(' + baseUrl + '/img/leagues/'+item.photo+ ')'}">
</a>
</div>
</div>
</div>
</div>
</template>
<script>
...
export default {
...
props: ['leagueId'],
mounted(){
setTimeout( function(){
$('.slick').not('.slick-initialized').slick({slidesToShow: 3, infinite: false});
} , 10000 );
},
created() {
this.getTopLeague([{league_id: this.leagueId}]) // this is ajax if load first
},
computed: {
...mapGetters([
'getListLeague'
]),
items() {
const n = ['getListLeague']
return this[n[0]] // this is response ajax // exist 5 league
}
},
methods: {
...mapActions([
'getTopLeague'
]),
changeLeague(leagueId) {
this.getTopLeague([{league_id: leagueId}]) // this is ajax if a link clicked
setTimeout( function(){
$('.slick').not('.slick-initialized').slick({slidesToShow: 3, infinite: false});
console.log('test')
} , 10000 );
}
}
}
</script>
When loaded the first time, there are 5 items of data displayed in the form of sliders. And the slider works. But if I click the another tab. For example I click League B, the slider not works. Whereas the result of console.log('test') had run
How can I solve it?
