I have three templates. AddCard.vue , ImageCard.vue and VideoCard.vue
AddCard.vue has two buttons on it one is to add the Image Card and Other To Add the video Card.. I need to add components based on the button click. Here are three templates and my index.html file.
index.html

I need to add components dynamically one after another in the <div id="dynamic_components"> . User can add as many as cards they want.
How do I add the components dynamically. Please point me to a tutorial.
Uses v-for + dynamic component.
Vue.config.productionTip = false
Vue.component('card1', {
template: '<div>Card:<span style="background-color:green">{{title}}</span></div>',
props: ['title']
})
Vue.component('card2', {
template: '<div>Card:<span style="background-color:blue">{{title}}</span></div>',
props: ['title']
})
Vue.component('card3', {
template: '<div>Card:<span style="background-color:yellow">{{title}}</span></div>',
props: ['title']
})
new Vue({
el: '#app',
data() {
return {
cards: [
{'card': {'title': 'I am one card1'}, 'card-type':'card1'},
{'card': {'title': 'I am one card2'}, 'card-type':'card2'}
]
}
},
computed: {
computedNoCard1: function () {
let availableCards = new Set(['card2', 'card3'])
return this.cards.filter((item) => {
return availableCards.has(item['card-type'])
})
}
},
methods: {
addCard: function () {
let supportedCards = ['card1', 'card2', 'card3']
let seed = Math.floor(Math.random()*supportedCards.length)
this.cards.push({'card': {'title': 'I am new card for ' + supportedCards[seed]}, 'card-type': supportedCards[seed]})
}
}
})

I am trying to add a task to a tasklist in Vue based on the input and add task button, but I keep getting the error "taskList is not defined". Does anybody see how to fix this problem? The code is as following:
<template>
<div id="input">
<form>
<input v-model="task.name">
<button v-on:click="addTask" v-bind:value="task.name">+</button>
</form>
<ol>
<div v-for="task in taskList" :key="task.id">
{{ task.name }}
<div v-if="task.completed">
<h2> Done </h2>
</div>
<div v-else>
<h2> Not done</h2>
</div>
</div>
</ol>
</div>
</template>
<script>
export default {
name: 'AddTask',
data: function() {
return {
taskList: [
{
name: 'task', completed: false, id: 3
}
] }
},
methods: {
addTask: function (task) {
taskList.push(task);
alert('test');
}
}
}
</script>
Ps. any other Vue tips are welcome as well.
You need to separate out your taskList and the current task you're adding, decouple it as a new object, then add it to your taskList array.
When referring to items in your data object you need to use the this keyword – e.g this.taskList rather than taskList:
new Vue({
el: "#app",
data: {
id:1,
taskList: [],
currentTask:{
completed:false,
name:'',
id:this.id
}
},
methods: {
addTask: function() {
let newTask = {
completed:this.currentTask.completed,
name:this.currentTask.name,
id:this.currentTask.id
}
this.taskList.push(newTask);
this.id++;
//alert('test');
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<div id="input">
<ol>
<li v-for="task in taskList" :key="task.id">
{{ task.name }}
<input type="checkbox"
:checked="task.completed"
#change="task.completed = !task.completed">
<span v-if="task.completed">
Done
</span>
<span v-else>
Not Done
</span>
</li>
</ol>
<input type="text" v-model="currentTask.name">
<button v-on:click="addTask">+</button>
</div>
</div>
From what I see in your template you use tasklist but you define it as taskList You will want to make sure your names are in the same case. Usually you'll see camelCase in vue, but other popular ones are snake_case and PascalCase
I would like to push the input to the array. When I press the button to add the items nothing happens. I've searched multiple websites but it seems that I am too dumb to find the right code :(
Do anyone know whats the problem with the code:
<!DOCTYPE html>
<head>
<title>Clientseitige Webentwicklung mit Vue.js</title>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
<div id="app_basic">
<ul>
<li v-for="value in cars">{{ value }}</li>
</ul>
<input id="input1" type="text" v-model="newFarbe" placeholder="farbe">
<input id="input2" type="text" v-model="newMarke" placeholder="marke">
<input id="input3" type="text" v-model="newPS" placeholder="ps">

</div>
<script>
var app_basic= new Vue(
{
el: '#app_basic',
data: {
cars:{
farbe: 'Blau',
marke: 'Ford',
ps: '240'
}
},
methods:{
addCar: function() {
this.cars.push({farbe : this.newFarbe, marke : this.newMarke, ps : this.newPS});
this.newFarbe='';
this.newMarke='';
this.newPS='';
}
}
});
</script>
</body>
</html>
cars should be an array and the inputs models should be defined in data. Moreover, it's better to have some sort of validation before the insertion:
new Vue({
el: '#app_basic',
data: {
cars: [
{
farbe: 'Blau',
marke: 'Ford',
ps: '240'
}
],
newFarbe: '',
newMarke: '',
newPS: ''
},
methods:{
addCar: function() {
if(!this.newFarbe || !this.newMarke || this.newPS) return;
this.cars.push({
farbe : this.newFarbe, marke : this.newMarke, ps : this.newPS
});
this.newFarbe='';
this.newMarke='';
this.newPS='';
}
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app_basic">
<ul>
<li v-for="value in cars">
{{ value.farbe }} -
{{ value.marke }} -
{{ value.ps }}
</li>
</ul>
<input id="input1" type="text" v-model="newFarbe" placeholder="farbe">
<input id="input2" type="text" v-model="newMarke" placeholder="marke">
<input id="input3" type="text" v-model="newPS" placeholder="ps">
<button v-on:click="addCar">Hinzufügen</button>
</div>
Consider the following code.
<template>
<div class="card-container">
<div class="row">
<div class="col s12">
<a #click="addCard()">Add Card</a>
</div>
</div>
<div class="row">
<div v-for="(card, index) in cards" :key="index">
<div class="card-panel">
<span class="card-title">Card Title</span>
<div class="card-action">
<a #click="deleteCard(index)">Delete</a>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
data: function() {
return {
cards: []
}
},
methods: {
addCard: function() {
this.cards.push({
description: "",
});
},
deleteCard: function(index) {
this.cards.splice(index,1);
}
},
}
</script>
How to make the cards be grouped so that there are 4 rows and each row contains 4 cards? Upon reaching the fourth row the new cards go to the next page.
I thought I could use something like this codepen.io/parths267/pen/bXbWVv
But I have no idea how to get these cards organized in a pagination system.
The view would look something like this
My solution is calculate all cards of current page ahead.
Uses computed property to calculate the relate values which the pagination needs.
In below simple example (it is only one example, you need to add necessary validations as your actual needs, like boundary conditions) :
pages is the page count
cardsOfCurPage is the cards in current page
Then add one data property=pageIndex save the index of current page.
Anyway, keep data-driven in your mind.
List all arguments your pagination needs,
then declare them in data property or computed property.
execute the necessary calculations in computed property or methods.
PS: I don't know which css framework you uses, so I uses bootstrap instead.
Vue.component('v-cards', {
template: `<div class="card-container">
<div class="row">
<div class="col-12">
<a class="btn btn-danger" #click="addCard()">Add Card</a><span>Total Pages: {{pages}} Total Cards: {{cards.length}} Page Size:<input v-model="pageSize" placeholder="Page Size"></span>
</div>
</div>
<div class="row">

<p><a class="badge" #click="gotoPrev()">Prev</a>- {{pageIndex + 1}} -<a class="badge" #click="gotoNext()">Next</a></p>

return {
cards: [],

}
},
computed: {

return Math.floor(this.cards.length / this.pageSize) + 1
},
cardsOfCurrPage: function () {
return this.cards.slice(this.pageSize * this.pageIndex, this.pageSize * (this.pageIndex+1))
}
},
methods: {
addCard: function() {
this.cards.push({
description: this.cards.length,
});
},
deleteCard: function(index) {
this.cards.splice(index,1);
},
gotoPrev: function() {this.pageIndex -=1},
gotoNext: function() {this.pageIndex +=1}
},
})
new Vue({
el: '#app',

return {

i want to bind my button only on the element that i added to the cart, it's working well when i'm not in a loop but in a loop anything happen. i'm not sure if it was the right way to add the index like that in order to bind only the item clicked, if i don't put the index every button on the loop are binded and that's not what i want in my case.
:loading="isLoading[index]"
here the vue :
<div class="container column is-9">
<div class="section">
<div class="columns is-multiline">
<div class="column is-3" v-for="(product, index) in computedProducts">
<div class="card">
<div class="card-image">
<figure class="image is-4by3">
<img src="" alt="Placeholder image">
</figure>
</div>
<div class="card-content">
<div class="content">
<div class="media-content">
<p class="title is-4">{{product.name}}</p>
<p class="subtitle is-6">Description</p>
<p>{{product.price}}</p>
</div>
</div>
<div class="content">
<b-button class="is-primary" #click="addToCart(product)" :loading="isLoading[index]"><i class="fas fa-shopping-cart"></i> Ajouter au panier</b-button>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
here the data :
data () {
return {
products : [],
isLoading: false,
}
},
here my add to cart method where i change the state of isLoading :
addToCart(product) {
this.isLoading = true
axios.post('cart/add-to-cart/', {
data: product,
}).then(r => {
this.isLoading = false
}).catch(e => {
this.isLoading = false
});
}
You can change your isLoading to an array of booleans, and your addToCart method to also have an index argument.
Data:
return {
// ...
isLoading: []
}
Methods:
addToCart(product, index) {
// ...
}
And on your button, also include index:
#click="addToCart(product, index)"
By changing isLoading to an empty array, I don't think isLoading[index] = true will be reactive since index on isLoading doesn't exist yet. So you would use Vue.set in your addToCart(product, index) such as:
this.$set(this.isLoading, index, true)
This will ensure that changes being made to isLoading will be reactive.
Hope this works for you.
add on data productsLoading: []
on add to cart click, add loop index to productsLoading.
this.productsLoading.push(index)
after http request done, remove index from productsLoading.
this.productsLoading.splice(this.productoading.indexOf(index), 1)
and check button with :loading=productsLoading.includes(index)
You can create another component only for product card,
for better option as show below
Kindly follow this steps.
place the content of card in another vue component as shown below.
<!-- Product.vue -->
<template>
<div class="card">
<div class="card-image">
<figure class="image is-4by3">
<img src="" alt="Placeholder image">
</figure>
</div>
<div class="card-content">
<div class="content">
<div class="media-content">
<p class="title is-4">{{product.name}}</p>
<p class="subtitle is-6">Description</p>
<p>{{product.price}}</p>
</div>
</div>
<div class="content">
<b-button class="is-primary" #click="addToCart(product)" :loading="isLoading"><i class="fas fa-shopping-cart"></i> Ajouter au panier</b-button>
</div>
</div>
</div>
</templete>
<script>
export default {
name: "Product",
data() {
return {
isLoading: false
}
},
props: {
product: {
type: Object,
required: true
}
},
methods: {
addToCart(product) {
this.isLoading = true
axios.post('cart/add-to-cart/', {
data: product,
}).then(r => {
this.isLoading = false
}).catch(e => {
this.isLoading = false
});
}
}
}
</script>
Change your component content as shown below.
<template>
<div class="container column is-9">
<div class="section">
<div class="columns is-multiline">
<div class="column is-3" v-for="(product, index) in computedProducts">
<product :product="product" />
</div>
</div>
</div>
</div>
</templete>
<script>
import Product from 'path to above component'
export default {
components: {
Product
}
}
</script>
so in the above method you can reuse the component in other components as well.
Happy coding :-)
First thing first I'm new to vue.js.
what I'm trying to do when the user click on the expander anchor tag in the item-preview component the item-details will display and the item-preview will be hide. Now the problem occurs when the item-preview displayed and i'm trying to toggle it by clicking its own expander anchor tag. I do not whats wrong with this.
Here is my HTML templates.
<script type="text/x-template" id="grid">
<div class="model item" v-for="entry in data">
<item-preview v-bind:entry="entry" v-if="entry.hide == 0">
</item-preview>
<item-details v-bind:entry="entry" v-if="entry.hide == 1">
</item-details>
</div>
</script>
<script type="text/x-template" id="item-preview">
<header class="preview">
<a class="expander" tabindex="-1" v-on:click="toggle(entry)"></a>
<span class="name rds_markup">
{{ entry.name }}
</span>
</header>
</script>
<script type="text/x-template" id="item-details">
<div class="edit details">
<section class="edit" tabindex="-1">
<form action="#">
<fieldset class="item name">
<a class="expander" v-on:click="toggle(entry)"></a>
{{ entry.name }}
</fieldset>
</form>
</section>
</div>
</script>
And here how I called the grid component on my view.
<grid
:data="packages">
</grid>
And for my Vue implementation
var itemPreview = Vue.component('item-preview',{
'template':"#item-preview",
'props':{
entry:Object
},
methods:{
toggle:function(entry){
entry.hide = !!entry.hide;
return true;
}
}
});
var itemDetails = Vue.component('item-details',{
'template':"#item-details",
'props':{
entry:Object
},
methods:{
toggle:function(entry){
entry.hide = !!entry.hide;
return true;
}
}
});
var grid = Vue.component('grid',{
'template':"#grid",
'props':{
data:Array,
},
components:{
'item-preview': itemPreview,
'item-details': itemDetails
},
methods:{
toggle:function(entry){
entry.hide = !!entry.hide;
return true;
}
}
});
var vm = new Vue({
el:'#app',
data:{
message:'Hello',
packages:{}
},
ready:function(){
this.fetchPackages();
},
methods:{
fetchPackages:function(){
this.$http.get(url1,function( response ){
this.$set('packages',response);
});
},
}
});
Silly me. It took me 30minutes to figure out what is wrong with this code.
What I did to fix this is instead of entry.hide = !!entry.hide; I use entry.hide = true in item-preview component and in the item-details entry.hide = false. this fix my issue.
