Horizontally draggable quasar q-cards using vue.draggable.next - vue.js

I've seen a few 'solutions' online about this but to no avail for us. We're working with the quasar framework and trying to setup a horizontally wrapped set of that are are draggable (for re-ordering). Below is the basic stub of the code we're working with to get this going. However, we're not able to get the cards to layout horizontally everything is stacked in a list. What are we doing wrong?
<template>
<draggable
v-model="items"
group="items"
direction="horizontal"
item-key="id"
#start="drag = true"
#end="drag = false"
>
<template #item="{ element }">
<q-card class="card">
<q-img src="~assets/temp/bb-auto.png" :alt="`Image ${element.name}`">
<div class="absolute-bottom text-subtitle2 text-center">
Image {{ element.name }}
</div>
</q-img>
</q-card>
</template>
</draggable>
</template>
<script setup lang="ts">
import { ref } from 'vue';
import draggable from 'vuedraggable';
const drag = ref(false);
const items = ref([
{ name: 'item1' },
{ name: 'item2' },
{ name: 'item3' },
{ name: 'item4' },
{ name: 'item5' },
]);
</script>
<style scoped>
.card {
max-height: 200px;
max-width: 200px;
display: flex;
}
</style>

Turns out our overall structure was incorrect and once we sorted that out was able to back this into the draggable. We then had to basically treat our as the row.
<template>
<draggable
v-model="items"
group="items"
class="q-pa-md row items-start q-gutter-md"
direction="horizontal"
item-key="name"
#start="drag = true"
#end="drag = false"
>
<template #item="{ element }">
<q-card class="card">
<q-img src="~assets/temp/bb-auto.png" :alt="`Image ${element.name}`">
<div class="absolute-bottom text-subtitle2 text-center">
Image {{ element.name }}
</div>
</q-img>
</q-card>
</template>
</draggable>
</template>
<script setup lang="ts">
import { ref } from 'vue';
import draggable from 'vuedraggable';
const drag = ref(false);
const items = ref([
{ name: 'item1' },
{ name: 'item2' },
{ name: 'item3' },
{ name: 'item4' },
{ name: 'item5' },
]);
</script>
<style scoped>
.card {
width: 100%;
max-height: 200px;
max-width: 200px;
display: flex;
}
</style>

nuxtjs add and remove class on click on elements

I am new in vue and nuxt and here is my code I need to update
<template>
<div class="dashContent">
<div class="dashContent_item dashContent_item--active">
<p class="dashContent_text">123</p>
</div>
<div class="dashContent_item">
<p class="dashContent_text">456</p>
</div>
<div class="dashContent_item">
<p class="dashContent_text">789</p>
</div>
</div>
</template>
<style lang="scss">
.dashContent {
&_item {
display: flex;
align-items: center;
}
&_text {
color: #8e8f93;
font-size: 14px;
}
}
.dashContent_item--active {
.dashContent_text{
color:#fff;
font-size: 14px;
}
}
</style>
I tried something like this:
<div #click="onClick">
methods: {
onClick () {
document.body.classList.toggle('dashContent_item--active');
},
},
but it changed all elements and I need style change only on element I clicked and remove when click on another
also this code add active class to body not to element I clicked
This is how to get a togglable list of fruits, with a specific class tied to each one of them.
<template>
<section>
<div v-for="(fruit, index) in fruits" :key="fruit.id" #click="toggleEat(index)">
<span :class="{ 'was-eaten': fruit.eaten }">{{ fruit.name }}</span>
</div>
</section>
</template>
<script>
export default {
name: 'ToggleFruits',
data() {
return {
fruits: [
{ id: 1, name: 'banana', eaten: false },
{ id: 2, name: 'apple', eaten: true },
{ id: 3, name: 'watermelon', eaten: false },
],
}
},
methods: {
toggleEat(clickedFruitIndex) {
this.fruits = this.fruits.map((fruit) => ({
...fruit,
eaten: false,
}))
return this.$set(this.fruits, clickedFruitIndex, {
...this.fruits[clickedFruitIndex],
eaten: true,
})
},
},
}
</script>
<style scoped>
.was-eaten {
color: hsl(24, 81.7%, 49.2%);
}
</style>
In Vue2, we need to use this.$set otherwise, the changed element in a specific position of the array will not be detected. More info available in the official documentation.

How to give a dynamically rendered element it's own data value & target it in it's parent component?

I have a BaseMenuItem component that has normal button elements as well as special news elements.
I have added a ticker effect to the news type els and want to stop the ticker on that element when it's clicked. Currently the click event stops the ticker effect on the whole group.
How can I target a single element from that group?
There are two methods, openNews one showing the specific news article that the element is linked to.
And clearItemType that clears the itemType upon recieving the emitted event from the BaseMenuItem component.
I'm just not sure which element to target to change it's itemType.
Does Vuejs have a way to make an unique data value for dynamically generated elements?
If you need anymore information please let me know!
Cheers!

clearItemType() {

return
},
</script>
EDIT: I edited since your latest comment. See below
To target the exact element within your v-for that fired the event, you can use $refs by using an index :
<MainMenuItem v-for="(item, index) in items" :ref="`menuItem--${index}`" #stop-ticker="clearItemType(index)" />
In your method:
clearItemType(index){
console.log(this.$refs[`menuItem--${index}`])
// this is the DOM el that fired the event
}
Edited version after your comments:
If you pass the exact same prop to each el of your v-for you wont be able to modify its value just for one child in the parent context.
Instead, keep an array of distinctive values in your parent. Each child will receive one specific prop that you can change accordingly in the parent either by listening to an child emitted event or by passing index as click event as I've done below for simplicity.
See snippet below
Vue.config.productionTip = false;
const Item = {
name: 'Item',
props: ['name', 'isActive'],
template: `<div>I am clicked {{ isActive }}!</div>`,
};
const App = new Vue({
el: '#root',
components: {
Item
},
data: {
items: ["item1", "item2"],
activeItemTypes: []
},
methods: {
toggle(index) {
this.activeItemTypes = this.activeItemTypes.includes(index) ? this.activeItemTypes.filter(i => i !== index) : [...this.activeItemTypes, index]
}
},
template: `
<div>
<Item v-for="(item, i) in items" :name="item" #click.native="toggle(i)" :isActive="activeItemTypes.includes(i)"/>

`,

The route for "http://localhost:3000/" returns the index.vue page.
In this vue page, I have a component with a search form. Once you complete these form and hit the seach button, it will re-direct to a results page
if this.form.keyword = "Data", the next URL will be "http://localhost:3000/jobs?q=Data" and it will be using the jobs.vue page.
The issue I'm running into is the CSS is not being loaded from the jobs.vue page. It's still coming from the index.vue page for some reason. If I refresh the page, then the CSS from jobs.vue is loading. I need the CSS to load from jobs.vue on the initial redirect. All of the query data is working as expected so thats a plus.
However, the following CSS is being applied from index.vue for some reason instead of the CSS from the jobs.vue page -
display: flex;
justify-content: center;
Does anyone know whats going on here? This app is SSR and not SPA.
You have to scope your css from the index.vue page to the other pages with the scoped directive (see docs https://vue-loader.vuejs.org/guide/scoped-css.html)
<style scoped>
/* local styles */
</style>
<style>
/* global styles */
</style>
You can add your global CSS in your layouts/default.vue file.
This solved the issue -
methods: {
onSubmit() {
window.location = 'http://localhost:3000/jobs?q=' + this.form.keyword;
}
},

Vue - passing apollo query result from parent to child component

I have this parent component which makes a call to this apollo query:
<template>
<div class="row" style="flex-wrap: nowrap; width:102%">
<BusinessContextTeamPanel :business_contexts="business_contexts"></BusinessContextTeamPanel></BusinessContextTeamDetailPanel>
</div>
</template>
<script>
apollo: {
business_contexts: {
query: gql`query ($businessContextId: uuid!) {
business_contexts(where: {id: {_eq: $businessContextId }}) {
id
businessContextTeams {
id
team {
name
id
}
role
}
}
}`,
variables: function() {
return {
businessContextId: this.currentContextId
}
}
}
},
</script>
My child component( BusinessContextTeamPanel) takes the input props and uses it like this:
<template>
<div v-if="business_contexts.length > 0">
<div v-for="teams in business_contexts" :key="teams.id">
<div v-for="team in teams.businessContextTeams" :key="team.id" style="padding-top: 20px;min-width: 400px">
<div style="height: 25px; color: #83d6c0;">
<div style="width: 7%; font-size: 10px; float: left; padding-top: 8px; cursor: pointer;" class="fa fa-minus-circle" ></div>
<div style="width: 50%; float: left; padding-right: 10px;">
<div class="gov-team-text" #click="editTeam(team)">{{ team.team.name }}</div>
</div>
<div style="width: auto; float: right;">
<b-badge variant="light">{{ team.role }}</b-badge>
</div>
<div style="width: 45%; margin-left: 4%; float: right;">
</div>
</div>
<div style="clear: both; margin-bottom: 15px;"></div>
</div>
</div>
</div>
</template>
The v-if here throws
Cannot read property 'length' of undefined
while the v-for works.
And when I'm trying to use the props in a child method(loadData()) which is called on child component mount hook, I get also undefined
<script>
import Treeselect from '#riophae/vue-treeselect';
import _ from "lodash";
export default {
name: "BusinessContextTeamPanel",
components: { Treeselect },
props: ['business_contexts'],
data() {
return {
itemModel: {},
allRoles: [],
formTitle: "",
filteredTeams: [],
showNoTeamMsg: false
}
},
mounted() {
this.loadData();
},
methods: {
loadData() {
let roles = [];
_.forEach(["Admin", "Contributor", "Owner", "Master", "Viewer", "User"], function (role) {
roles.push({id: role, label: role});
});
console.log(this.business_contexts); // here I get undefined
this.allRoles = roles;
this.showNoTeamMsg = this.business_contexts.length === 0;
}
}
}
</script>
What am I missing?
Either your apollo query isn't working, or it isn't ready in time for the child component's attempted use of it.
For debugging, in the parent component's template add {{ business_contexts }}, just so you can eyeball it. This will confirm whether the query is working.
If the query is working, it could be that your child component is trying to access the data before it's ready. Change your v-if from
<div v-if="business_contexts.length > 0">
to
<div v-if="business_contexts && business_contexts.length > 0">
EDIT: better yet, change the parent component to not try to load the child at all, until the parent has the data:
<BusinessContextTeamPanel v-if="business_contexts" :business_contexts="business_contexts"></BusinessContextTeamPanel></BusinessContextTeamDetailPanel>

Use method in template, out of instance vue

This is warning when i click on go to contact in tab about: "Property or method "switchTo" is not defined on the instance but referenced during render. Make sure to declare reactive data properties in the data option.
(found in component )."
How do I fix this?
new Vue({
el: '#app',
data: {
currentPage: 'home',
},
methods: {
switchTo: function(page) {
this.currentPage = page;
}
},
components: {
home: {

Just change your about template to this

new Vue({

<template id="contact">
<p>contact</p>
</template>
I already solved a problem like this in this question: Calling methods in Vue build
It's not the same problem so it's not a repeated question, but the answer is the same:
In the created hook, add the component to window.componentInstance like this:
methods: {
foo () {
console.log('bar')
}
},
created () {
window.componentInstance = this
}
Then you can call the method anywhere like this:
window.componentInstance.foo()
