Toggle class(or change style) of element when element in clicked, Vuejs

The way i am getting data is little bit complicated. I have "tweets" array where data is stored and each tweet is a card where i successfully change style when card is clicked(markTweet function), but there are also replies for each tweet which are shown same as tweets(each reply has its own card). The way i am getting data from server:
let replies = []
for(const tweet of tweets) {
let reply = await SQL('SELECT * FROM tweet_replies WHERE tweet_replies.conversation_id = ?', tweet.tweet_id)
replies.push(reply)
}
const data = {
tweets: tweets,
page: parseInt(currentPage),
numberOfPages: arr,
replies
}
Then i have component in vue. You can see replies are stored in tweets array in each tweet as tweetReplies.
In markReply func, am succesfully adding id to array.
<template>
<div class="container-full">
<div class="tweets-container">
<div
v-for="(tweet, i) in tweets"

</script>
I have tried to add replySelected in data and then when click is triggered in markReply i changed replySelected to true, but every reply of a tweet was then selected, which is not what i want.

If I understood you correctly try like following snippet:
const app = Vue.createApp({
data() {
return {
tweets: [{id: 1, tweet_id: 1, isSelected: true, tweet_text: 'aaa', tweetReplies: [{tweet_id: 11, tweet_text: 'bbb'}, {tweet_id: 12, tweet_text: 'ccc'}]}, {id: 2, tweet_id: 2, isSelected: false, tweet_text: 'ddd', tweetReplies: [{tweet_id: 21, tweet_text: 'eee'}, {tweet_id: 22, tweet_text: 'fff'}]}],
tweetActionIds: [],
}
},
methods: {
markTweet(tweetId, i) {
const idIndex = this.tweetActionIds.indexOf(tweetId)
this.tweets[i].isSelected = !this.tweets[i].isSelected
if (this.tweetActionIds.includes(tweetId)) {
this.tweetActionIds.splice(idIndex, 1)
} else {
this.tweetActionIds.push(tweetId)
}
},
markReply(replyId) {
const idIndex = this.tweetActionIds.indexOf(replyId)
if (this.tweetActionIds.includes(replyId)) {
this.tweetActionIds.splice(idIndex, 1)
} else {
this.tweetActionIds.push(replyId)
}
},
checkReply(r) {
return this.tweetActionIds.includes(r) ? true : false
}
},
})
app.mount('#demo')
.selected {color: red;}
<script src="https://cdn.jsdelivr.net/npm/vue#3/dist/vue.global.prod.js"></script>
<div id="demo">
<div class="container-full">
<div class="tweets-container">
<div v-for="(tweet, i) in tweets" :key="tweet.id">
<div
class="tweet-card"
:class="{ selected: tweet.isSelected }"
#click="markTweet(tweet.tweet_id, i)"
>
<div class="text">
<p v-html="tweet.tweet_text">
{{ tweet.tweet_text }}
</p>
</div>
</div>
<div class="replies">
<div
v-for="(reply, index) in tweet.tweetReplies"
:key="reply.tweet_id"
#click="markReply(reply.tweet_id, index)"
>
<div class="tweet-card tweet-reply">
<div class="text" :class="{selected: checkReply(reply.tweet_id)}">
<p>{{ reply.tweet_text }}</p>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
{{tweetActionIds}}
</div>

You can build on Nikola's answer by bypassing the extra step of adding isSelected to each individual Tweet by just checking if it's in the tweetActionIds array, and then do the same with the replies to keep it clean

How to control multiple checkbox in Vue

I have a checkbox component in Vue:
<template>
<div class="checkbox">
<input class="checkbox-input" name="input" type="checkbox" v-model="checkbox">
</div>
</template>
<script>
export default {
data(){
return {
checkbox: false
};
},
};
</script>
So in the parent component I want to control these checkbox. So here is my parent component:
<div class="card">
<div class="card-header">
<CheckBox />
</div>
<div class="card-body" v-for="item in cart" :key="item.product.id">
<div class="checkbox-area">
<CheckBox />
</div>
</div>
So checkbox in card-body can be added when user clicks to add. So if a user clicks 3 times, 3 checkbox are being added inside of card-body. What I am trying to achieve is, as you see in card-header there is another checkbox, and when this checkbox is clicked, I want to check all the checkboxes inside card-body, and when it is unchecked in card-header, I want to unchcecked everything inside card-body.
So do you have any idea how to achieve this?
Thanks...

You can try like this :
Vue.component('checkbox', {
template: `
<div class="checkbox">
<input class="checkbox-input" name="input" type="checkbox" #change="getCheck" v-model="value">
</div>
`,
props: {
checked: {
type: Boolean,
default: false
}
},
data(){
return {
value: this.checked
};
},
methods: {
getCheck() {
this.$emit("set-checked", this.value)
}
},
watch: {
checked(){
this.value = this.checked
}
}
})
new Vue({
el: '#demo',
data(){
return {
all: false,
cart: [
{id: 1, check: false},
{id: 2, check: false},
{id: 3, check: true},
{id: 4, check: false}
]
};
},
watch: {
cart() {
this.cart.find(c => c.check === false) ? this.all = false : this.all = true
}
},
methods: {
checkAll(val) {
this.all = val
this.cart = this.cart.map(c => {
c.check = val
return c
})
},
checkItem(id) {
this.cart = this.cart.map(c => {
if(c.id === id) {
c.check = !c.check
}
return c
})
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="demo">
<div class="card">
<div class="card-header">
<p>All</p>
<checkbox :checked="all" #set-checked="checkAll" />
</div>
<br/>
<div class="card-body" v-for="item in cart" :key="item.id">
<div class="checkbox-area">
<checkbox :checked="item.check" #set-checked="checkItem(item.id)" />
</div>
</div>
</div>
</div>

First of all you need to add some props to your Component. than a wachter to emit a sync when the Value of the checkbox changes.
<template>
<div class="checkbox">
<input class="checkbox-input" name="input" type="checkbox" v-model="value">
</div>
</template>
<script>
export default {
props: {
checked: {
type: Boolean,
default: false
}
}
data(){
return {
value: this.checked
};
},
watch: {
value(){
this.$emit("update:checked", this.value)
}
}
};
</script>
on the cart you need to watch for theses changes an than you can check/uncheck all the items.
<template>
<div class="card">
<div class="card-header">
<CheckBox :checked.sync="global"/>
</div>
<div class="card-body" v-for="item in cart" :key="item.product.id">
<div class="checkbox-area">
<CheckBox :checked.sync="item"/>
</div>
</div>
</div>
</template>
<script>
export default {
data(){
return {
global: false,
cart: [
false,
false,
false
]
};
},
watch: {
global(){
for (let i = 0; i < this.cart.length; i++) {
this.chart[i] = this.global
}
}
}
};
</script>
I have not tested this code, but this should work...

Using checkbox input as custom components can be a little tricky see if this code can help you:
code sandbox
Vue.component('checkbox', {
template: `
<label>
<input type="checkbox" :value="value" v-model="deltaValue" />
{{ label }}
</label>
`,
name: "checkbox",

prop: 'modelValue',

modelValue: {
type: [Array, Boolean],

},
},
computed: {
deltaValue: {

return this.modelValue;
},
set(value) {
this.$emit("update:modelValue", value);
},
},
},

Setting up a filter in vue.js

Creating a filter to sort through quotes data, but having problems with creating the correct functions.
HTML:
<template>
<div class="home">
<h1>{{ message }}</h1>
<h3> Theme filter: </h3>
<div>
<button v-on:click="userFilterKey = 'movies'"> Search movies</button>
<button v-on:click="userFilterKey= 'all'"> Search all</button>
<button v-on:click="userFilterKey= 'games'"> Search games </button>
<div v-for="quote in quotes" v-bind:key="quote.id">
<p>Souce: {{ quote.source }} </p>
<p>Quote: {{ quote.quote }} </p>
<p>Theme: {{ quote.theme }} </p>
</div>
</div>
</div>
</template>
Script:
import axios from "axios";
export default {
data: function () {
return {
message: "Welcome to Vue.js!",
quotes: [],
userFilterKey: "all",
};
},
methods: {
userFilter: function () {
return this[this.userFilterKey];
},
all: function () {
return this.quotes;
},
movies: function () {
return this.quotes.filter((theme) => (quotes.theme = "movies"));
},
books: function () {
return this.quotes.filter((theme) => (quotes.theme = "books"));
},
quotesIndex: function () {
axios
.get("linktodata")
.then((response) => {
this.quotes = response.data;
});
},
How do I create filters to sort through the theme key of the quotes array within my link?

Use a computed prop.
new Vue({
el: '#app',
data: () => ({
quotes: [{
id: 1,
source: 'a',
quote: '',
theme: ''
},
{
id: 2,
source: 'b',
quote: '',
theme: 'movies'
},
{
id: 3,
source: 'c',
quote: '',
theme: 'games'
}
],
userFilterKey: "all"
}),
computed: {
filteredQuotes() {
if (this.userFilterKey === 'all') {
return this.quotes
}
return this.quotes.filter(v => v.theme === this.userFilterKey)
}
}
})
<div id="app">
<button #click="userFilterKey = 'all'"> Search all </button>
<button #click="userFilterKey = 'movies'"> Search movies</button>
<button #click="userFilterKey = 'games'"> Search games </button>
<div v-for="quote in filteredQuotes" :key="quote.id">
<p>Souce: {{ quote.source }} </p>
<p>Quote: {{ quote.quote }} </p>
<p>Theme: {{ quote.theme }} </p>
</div>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.14/vue.min.js"></script>

Try using Pipes. Its something that does the filter in client side and is faster. may be that solves your problem

Tried to go with the basic idea of the structure you laid out. I added:
id to all items, so they can be identifed
children to appropriate items, so you can keep track of what's in them
const store = new Vuex.Store({

{ id: 1, children: ['1.1', '1.2'] },

<custom-table v-for="item in tables" :key="'table-' + item.id" :c-table="item" />
</div>
With this setup you can change the hierarchy quite easily: just delete an ID from one Array of children and add it to another (e.g. remove '1.1' from table ID 1's children array and add it to table ID 2's children array - everything moved to table ID 2. tryMovingList() does exactly this - this method/action is not foolproof, just for you to try out moving a whole list)
There could be other patterns to solve this problem (like a real linked list data structure or the mediator pattern), but for smaller apps this is OK, I think (I would use it... :) ).
ONE PIECE OF ADVICE
If you want to store state in localStorage on mutations, don't do it by yourself - use Vuex's integrated subscribe mechanism: https://vuex.vuejs.org/api/#subscribe

vue js axios cannot read property 'data' of undefined

I am trying to get the json to display in cards or list after search. The search part seems to be working since I can see the call to the API with the text written in the search box in the console. but nothing is displaying and I get this error TypeError: Cannot read property 'data' of undefined. I don't think I am getting the json path correct.

you are missing res.data object
this.results = res.data.success.data;
this.api.prevPageToken = res.data.success.data.prevPageToken;
this.api.nextPageToken = res.data.success.data.nextPageToken;
