Owl carousel not working with loop in vuejs and axios - vue.js

I am using vue in my existing codeigniter project by including via CDN.
i am having problem in using owl carousel. i fetched data using axios and populated in div using v-for method. but it seems owl carousel not working.
I have also added screenshot of what i am facing.
here is the script part
<script src="https://cdn.jsdelivr.net/npm/vue#2.6.12/dist/vue.js"></script>
<script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
<script>
new Vue({
el: '#offerstab',
data () {
return {
touroffers: [],
caroffers: [],
hoteloffers: [],
cruiseoffers: [],
flightoffers: [],
}
},
methods: {
getOffers () {
axios
.get('https://www.happyvoyaging.com/api/offers/listcustom',{
params: {
category: ['tours','flight','cars','cruise','rail','hotel']
}
})
.then(res => (this.touroffers = res.data.off_tours,this.caroffers = res.data.off_cars,this.hoteloffers = res.data.off_hotels,this.cruiseoffers = res.data.off_cruises,this.flightoffers = res.data.off_flights))
},
},
mounted() {
this.getOffers();
},
})
</script>
this is my html part where i want owl carousel to be initiated.
<div id="offerstab">
<div class="owl-carousel owl-carousel-nav-dark" data-items="3" data-loop="true" data-nav="true">
<div v-for="touroffer in touroffers" class="theme-inline-slider-item">
<div class="banner _h-33vh _br-5 banner-">
<div class="banner-bg" v-bind:style="`background-image:url('${touroffer.thumbnail}');`"></div>
<div class="banner-mask banner-mask-half"></div>
<a class="banner-link" href="#"></a>
<div class="banner-caption _ta-c banner-caption-bottom">
<h5 class="banner-title _tt-uc">{{ touroffer.title }}5</h5>
<p class="banner-subtitle">Top deals from most visited cities</p>
</div>
</div>
</div>
</div>
</div>
this is how its looking, it should show 3 columns here but it is showing one below another
This is what i expect, as it works well with static code without vue
This is data in touroffers after axioscall

if-emoji lookup table with Vue

I'm using the npm module if-emoji to detect whether a user can view emojis or not. There is a similar tool in Modernizr.
If the user can't view emojis, I'm displaying an image of the emoji instead. So my Vue HTML looks like this:
<h2 v-if="this.emojis">😄</h2>
<h2 v-if="!this.emojis"><img src="https://example.com/emoji.png">/h2>
Does this still download the image for users who can view emojis, therefore using bandwidth unecessarily?
And is there a more efficient way of doing this, so that I don't need to go and add v-if every time I use an emoji? Can there be some sort of lookup table, if there's an emoji and !this.emojis?
You can solve this also by creating your own vue.component
<emojiorimage usesmily="false" smily="😄" imgpath="https://i.stack.imgur.com/QdqVi.png"></emojiorimage>
that capsulates the decision if image or smily inside itself.
var app = new Vue({
el: "#app",
data: function(){
return {
extendedCost: 0,
}
},
components: { "emojiorimage" : {
template : `
<h2>
usesmily is {{usesmily}}<br/>
<div v-if="usesmily === 'true'">{{ smily }}</div>
<div v-else><img :scr="imgpath" width="50" height="50" :alt="imgpath" /></div>
</h2>`,
props: ["usesmily", "smily", "imgpath"],
}}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<h1>Emoji or Image</h1>
<emojiorimage
usesmily="false"
smily="😄"
imgpath="https://i.stack.imgur.com/QdqVi.png"
></emojiorimage>
<emojiorimage
usesmily="true"
smily="😎"
imgpath="https://i.stack.imgur.com/QdqVi.png"
></emojiorimage>
</div>
You can then feed it the isemoji from your npm package that you query once and store somewhere.
For seperate vue files it would look kind of like this:
emojiorimage.vue
<template>
<h2>
<div v-if="usesmily === 'true'">{{ smily }}</div>
<div v-else><img :scr="imgpath" width="50" height="50"
:alt="imgpath" /></div>
</h2>
</template>
<script>
export default {
props: ["usesmily", "smily", "imgpath"],
};
</script>
App.vue
<template>
<div id="app">
<h1>Emoji or Image</h1>
<emojiorimage
usesmily="false"
smily="😄"
imgpath="https://i.stack.imgur.com/QdqVi.png"
/>
<emojiorimage
usesmily="true"
smily="😎"
imgpath="https://i.stack.imgur.com/QdqVi.png"
/>
</div>
</template>
<script>
import emojiorimage from "./components/emojiorimage.vue";
export default {
components: {
emojiorimage,
},
};
</script>
index.html
<div id="app"></div>
index.js
import Vue from "vue";
import App from "./App";
Vue.config.productionTip = false;
new Vue({
el: "#app",
template: "<App/>",
components: { App }
});

Learning resources:
https://v2.vuejs.org/v2/guide/components.html
https://v2.vuejs.org/v2/guide/single-file-components.html
This should work as well:
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<h2 v-if="true">😄</h2>
<h2 v-else><img src="https://upload.wikimedia.org/wikipedia/commons/thumb/e/e0/SNice.svg/1200px-SNice.svg.png" width=15 height=15></h2>
<h2 v-if="false">😄</h2>
<h2 v-else><img src="https://upload.wikimedia.org/wikipedia/commons/thumb/e/e0/SNice.svg/1200px-SNice.svg.png" width=15 height=15></h2>
The v-if part only is part of the sourcecode if the statement is true - else the else statement is in instead. If the img tag is not part of the loaded source the image wont be loaded.
<h2 v-if="emojis">😄</h2>
<h2 v-else><img src="https://example.com/emoji.png"></h2>
Is probably the only way to improve your code as #Patrick Artner pointed out.
You do not need this. in the template
To the question if the image is loaded if it is not shown the simple answer is no. Vue only renders v-ifs when they are needed and does not render it - the image is loaded only if !emojis.
Thanks to #PatrickArtner who posted the idea of using a Vue component to render the emoji / image. Here is my final solution, which resizes the emoji / image to fit the surrounding text — it uses fitty to resize the emojis, and sets the images to height:1em;.
Emoji.vue
<template>
<div class="emojiContainer">
<span id="fittyEmoji" v-if="emojis">{{ insert }}</span>
<img v-if="!emojis" :src="insert" class="emojiImage">
</div>
</template>
<style scoped>
.emojiContainer {
display: inline;
}
.emojiImage {
height:1em;
}
</style>
<script src="fitty.min.js"></script>
<script>
import fitty from 'fitty';
import ifEmoji from 'if-emoji'
export default {
name: 'Emoji',
props: ['name'],
data: function() {
return {
insert: "",
emojis: false,
}
},
methods: {
insertEmoji(){
var names = ['frog', 'fire']
var emojis = ['🐸','🔥']
var urls = ['https://example.com/frog.png',
'https://example.com/fire.png']
if (this.emojis) {
this.insert = emojis[names.indexOf(this.name)];
} else {
this.insert = urls[names.indexOf(this.name)];
}
fitty('#fittyEmoji')
}
},
beforeMount() {
if (ifEmoji('🐸')) {
this.emojis = true;
} else {
this.emojis = false;
}
this.insertEmoji();
}
}
</script>
Then in your parent components you can just insert like this:
<template>
<div id="app">
<h1><Emoji name='frog'/> Frog Facts</h1>
<p>Lorem ipsum <Emoji name='fire'/><p>
</div>
</template>
<script>
import Emoji from '#/components/Emoji.vue'
export default {
components: {
Emoji,
},
};
</script>

How to add vue.js component multiple times #click?

I'm new to Vue and have been trying to figure this out for days without finding a solution that works...
How do I add an external vue-component multiple times #click on button?
Hopefully my pseudo-code below will explain what i'm trying to do.
<template>
<div>
<Piece/>
<!-- HERE I WANT TO ADD MULTIPLE "<Piece/>" #click on below button -->
<button type="button" #click="addPiece">Add Piece</button>
</div>
</template>
<script>
import Piece from "#/components/Piece.vue";
export default {
name: "PiecesModal",
components: {
Piece,
},
methods: {
addPiece () {
this.components.push(Piece)
}
},
};
</script>
Vue is "data driven"
Instead of wasting time "figuring this out for days", just read the excellent docs, List Rendering in this case...
const piece = Vue.component('Piece', {
props: ['number'],
template: `<div> Piece {{ number }} </div>`
})
const app = new Vue({
el: "#app",
components: { piece },
data() {
return {
counter: 0,
pieces: []
}
},
methods: {
addPiece() {
this.pieces.push(this.counter)
this.counter++
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<button type="button" #click="addPiece">Add Piece</button>
<hr>
<Piece v-for="piece in pieces" :key="piece" :number="piece"/>
</div>

VueJS - template variables not reactive with data variable

I'm making a chat system with socket.io and VueJS, so customers can talk to an admin. But when a client connects to the server, the variable in the data() updates. But the template is not updating.
Here is my code:
<template>
<div>
<div class="chats" id="chat">
<div class="chat" v-for="chat in chats">
<b>{{ chat.clientName }}</b>
<p>ID: {{ chat.clientID }}</p>
<div class="jens-button">
<img src="/icons/chat-bubble.svg">
</div>
</div>
</div>
</div>
</template>
<script>
let io = require('socket.io-client/dist/socket.io.js');
let socket = io('http://127.0.0.1:3000');
export default {
name: 'Chats',
data() {
return {
chats: [],
}
},
mounted() {
this.getClients();
this.updateClients();
},
methods: {
getClients() {
socket.emit('get clients', true);
},
updateClients() {
socket.on('update clients', (clients) => {
this.chats = clients;
console.log(this.chats);
});
}
},
}
</script>
Then I get this, the box is empty:
But I need to get this, this will only appear when I force reload the page. I don't know what I'm doing wrong...
Oke, I've found out where the problem was, in another component I used plain javascript which brokes the whole reactive stuff.

infinite loop when create infinite scroll using vue.js and laravel

good day; kindly need your support to finalize this issue i try to make infinite scrolle using laravel and vue.js and my proplem is get in finite loop to set request to data base and mu applocation hang up this is my code x component
<template>
<div class="container" style="margin-top:50px;">
<div class="row justify-content-center">
<div class="col-md-8">
<div class="card">
<div class="card-header"><strong> Laravel Vue JS Infinite Scroll - ItSolutionStuff.com</strong></div>
<div class="card-body">
<div>
<p v-for="item in list">
<a v-bind:href="'https://itsolutionstuff.com/post/'+item.slug" target="_blank">{{item.title}}</a>
</p>
<infinite-loading #distance="1" #infinite="infiniteHandler"></infinite-loading>
</div>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
mounted() {
alert()
console.log('Component mounted.')
},
data() {
return {
list: [],
page: 1,
};
},
methods: {
infiniteHandler($state) {
let vm = this;
this.$http.get('/Services?page='+this.page)
.then(response => {
return response.json();
}).then(data => {
$.each(data.data, function(key, value) {
vm.list.push(value);
});
$state.loaded();
});
this.page = this.page + 1;
},
},
}
</script>
this is my route
Route::get('/Services', 'ServicesController#Services');
Problem 1
You are binding to the distance property wrong.
Solution
Instead of <infinite-loading #distance="1" #infinite="infiniteHandler"></infinite-loading>
it should be
<infinite-loading :distance="1" #infinite="infiniteHandler"></infinite-loading>
Problem 2
In the code, this.page is being incremented before $http.get is resolved.
This may result in unintentional side effects.
Solution
As per the example in docs vue-infinite-loading hacker news example you should be incrementing the page after data is loaded.

Show child of this parent click vue

I want to show the immediate child after clicking on its parent. Its easy on jquery, hard on vue, how can I do it?
template:
<boxes inline-template>
<div class="white-box" #click="toggleTick">Purchase only
<div v-if="showTick"><i class="fas fa-check"></i></div>
</div>
</boxes>
js
Vue.component('boxes', {
data: function () {
return {
showTick: false
}
},
methods: {
toggleTick () {
this.showTick = !this.showTick
}
}
})
var app = new Vue({
el: '#app',
data: {
}
})
At the moment I have multiple "white-box" div, it shows the child div for all of them, I just want to show the div for the clicked parent's child.
You should have behavior that you expect :
Vue.component('boxes', {
data: function () {
return {
showTick: false
}
}
})
var app = new Vue({
el: '#app'
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<boxes inline-template>
<div class="white-box" #click="showTick = !showTick">
<span>
Purchase only
</span>
<div v-if="showTick">Component 1</div>
</div>
</boxes>
<boxes inline-template>
<div class="white-box" #click="showTick = !showTick">
<span>
Purchase only
</span>
<div v-if="showTick">Component 2</div>
</div>
</boxes>
</div>
Your white-boxes are sharing the same showTick variable, so clicking on one fo them changes the value for all of them.
There are 2 available solutions to this:
Have multiple boxes components and not multiple white-boxes under the same boxes component. Something take ends up looking like this in the DOM
<boxes>...</boxes>
<boxes>...</boxes>
<boxes>...</boxes>
Use an array for showTick and use an index when calling toggleClick. Also note that for the changes in the array to be reactive you need to use Vue.set.
I recommend the former solution.
