Vue v-for loop click event affecting all items - javascript

I've searched and couldn't see any answer that fits what I need. I have a v-for loop with a button on each item and used VueClipboard2 to copy text. Anytime the button is clicked, I do some css changes to indicated the item that was copied. What happens is that, if there's more than 1 item, clicking on any button affects affect every other item and does the same effect.
I want to limit the clicking to the "own" item being clicked.
Here's my code:
<template>
<div class="form" id="shorten">
<form class="" #submit.prevent="shortener($event, value)">
<div>
<div class="form__shortener">
<input
class="form-input"
type="url"
name="link"
id="link"
placeholder="shorten a url here"
aria-label="input a url"
v-model="value"
/>
<button class="form-btn btn">
{{ buttonText }}
<p v-if="loading" class="loading"></p>
</button>
</div>
<SlideXLeftTransition :delay="100">
<p v-if="error" class="error">Please enter a valid link</p>
</SlideXLeftTransition>
</div>
</form>
<SlideYUpTransition group>
<div v-for="(link, index) in links" :key="index" class="form__links">
<p class="form__links-main">
{{ link.mainUrl }}
</p>
<div class="center form__links-copy">
<p>
<a :href="link.shortenedUrl" class="form__links-copy-link no-decoration">{{ link.shortenedUrl }}</a>
</p>
<button
class="form__links-copyBtn btn"
:class="[copied === true ? 'copied' : '']"
v-clipboard:copy="link.shortenedUrl"
v-clipboard:success="onCopy"
v-clipboard:error="onError"
>
<span v-if="!loading && !copied">Copy</span>
<span v-if="copied">Copied!</span>
</button>
</div>
</div>
</SlideYUpTransition>
</div>
</template>
<script>
import { required, minLength } from 'vuelidate/lib/validators';

export default {

} else {
try {
this.loading = true;
this.buttonText = 'Loading';
const request = await axios.post('https://rel.ink/api/links/', { url: value });
this.loading = false;
this.buttonText = 'Shortened!';
setTimeout(() => {
this.buttonText = 'Shorten it!';
}, 1200);
this.shortenedUrl = `https://rel.ink/${request.data.hashid}`;
const mainUrl = request.data.url.length <= 20 ? request.data.url : `${request.data.url.slice(0, 30)}...`;
this.links.push({
shortenedUrl: `https://rel.ink/${request.data.hashid}`,
mainUrl,
});
localStorage.setItem('links', JSON.stringify(this.links));
} catch (error) {
this.showError();
console.log(error);
}
}
},
onCopy() {
this.copied = true;
setTimeout(() => {
this.copied = false;
}, 2500);
},
showError() {
this.error = true;
setTimeout(() => {
this.error = false;
}, 2000);
},
onError() {
alert('Sorry, there was an error copying that link. please reload!');
},
getLinks() {
if (localStorage.getItem('links')) this.links = JSON.parse(localStorage.getItem('links'));
},
},
components: {
SlideYUpTransition,
SlideXLeftTransition,
},
mounted() {
this.getLinks();
},
};
</script>
I would appreciate if anyone who help out.
Here's the live link: https://url-shortener-vue.netlify.app
To replicate, shorten two lines and click on the copy button on 1. It triggers all other items button.
Thank you.

Reason for your problem is
:class="[copied === true ? 'copied' : '']". SInce when you click any copy button, you change copied, and same class is used in all the iterations.
So, got the problem.
Solution is, you should have this copied corresponding to each link. So make your link as object.
link = [{ link: 'url...', copied: false}, {}, ...].
and, check for each link's copied value.

Am having issue implementing the javascript code with vue

Am very new to vuejs.am trying to replicate the javascript with vue. where a user can toggle button. I have a list of buttons and I would like to toggle the active class but remove the active class from all other buttons.. Is there a better way of writtting the function without the querySelector? Am really stuck..
<template>
<div #click="selectItem" class="menu-tabs">
<button type="btn" class="menu-tab-item active" data-target="#remis-transfer"> Transfer
</button>
<button type="btn" class="menu-tab-item text-muted" data-target="#bank-transfer">
Transfer Money
</button>
<button type="btn" class="menu-tab-item text-muted" data-target="#fueling">
Fueling
</button>
</div>
</template>
<script>
export default {
methods: {
selectItem(e) {
if (e.target.classList.contains("menu-tab-item") && !e.target.classList.contains("active")) {
const target = e.target.getAttribute("data-target")
menuTabs.querySelector(".active").classList.remove("active");
e.target.classList.add("active");
const menuSection = document.querySelector(".menu-section");
menuSection.querySelector(".menu-tab-content.active").classList.remove("active");
menuSection.querySelector(target).classList.add('active');
}
}
}
}
</script>
Look at the code
var Main = {
data() {
return {
active: 0,
buttonList: [
{
text: "Transfer",
target: "#remis-transfer",
},
{
text: "Transfer Money",
target: "#bank-transfer",
},
{
text: "Fueling",
target: "#fueling",
},
],
};
},
methods: {
selectItem(i) {
this.active = i;
},
},
};
var Ctor = Vue.extend(Main)
new Ctor().$mount('#app')
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.9/vue.js"></script>
<div id="app">
<div class="menu-tabs">
<button
type="btn"
class="menu-tab-item"
v-for="(item, index) in buttonList"
:class="[{ active: active == index }, { 'text-muted': active != index }]"
:data-target="item.target"
:key="index"
#click="selectItem(index)"
>
{{ item.text }}
</button>
</div>
</div>
You can simply define some states like:
data() {
return {
myActiveClass: 'active',
myMutedClass: 'text-muted'
}
},
and pass this myActiveClass and myMutedClass states to your elements like this:
class=menu-tab-item ${myMutedClass} ${myActiveClass}
with this approach, you can quickly achieve what you want. So when you want an element to not be active, in your function you can make myActiveClass = '', or if you want the text to lose muted class you can say myMutedClass = '' .
Just make sure to play with states in the way you want.

Nuxtjs: Axios Request does not work when switching to another route

i try to build a little clothing web shop with nuxtjs. You can choose the color on the details page. The details page represents a pice of clothing. The ColorMenu is a component. If you choose something a color, it will emit it back to the details page and will send a new details request to my backend.
However, changing the color only works if you don't choose another piece of clothing. If you choose another piece of clothing (so the route parameters will change) and choose another color in the menu, there is a always an error that it cannot load anything. it seems that it sends repeated requests until the request is blocked.
The details routes are built according to this scheme: localhost/details/{sellableId}/{ideaId}/{appearanceId}

Vue-js remember check box choices for every question

I'm making a quiz app. I have question selection menu and I need to save each checkbox state for each question. For example, if you were to select an answer for 1st question, I need to save your choices even if you skip to 3rd question so when you come back to 1st your old choices are still there.
Now the problem that I have is - my checkboxes aren't unique, they are same for each question. Please take a look at gif on what happens.
https://i.imgur.com/hua2NI8.gif
This is my code
<template>
<div v-if="loading"><loader></loader></div>
<div v-else class="main">
<h5 class="test-title">Test</h5>
<h5 class="choosequestion">
<font-awesome-icon icon="list-ul" style="margin-right: 8px" />Choose question
</h5>
<div v-dragscroll="true" class="questionsbox">
<!-- answered, current -->
<input v-for="(question, index) in questions" :key="index" :value="index + 1" #click="chooseQuestion(index)" class="questionbox" type="button" />
</div>
<div class="buttons">
<a class="ctlBtn">Restart</a>
<a class="ctlBtn">End</a>
</div>
<div class="questionmain">
<h5 class="questiontext">
<font-awesome-icon icon="question-circle" style="margin-right: 8px" />
{{ currentQuestion.question }}
</h5>
<ul>
<li
v-for="( answer, key ) in currentQuestion.answers"
:index="currentQuestion.key"
:key="answer.title"
>
<input v-model="checkedAnswers[key]" #change="answerClick" :id="answer.title" type="checkbox" />
<label :for="answer.title" >{{ answer.title }}</label>
</li>
{{ checkedAnswers }}
</ul>
<img
class="questionimg"
:src="currentQuestion.image_url"
/>
<a class="nextBtn" #click="nextQuestion"><font-awesome-icon icon="arrow-right" style="color: black;"/></a>
</div>
</div>
</template>
<script>
import { dragscroll } from "vue-dragscroll";
import Loader from "./Loader.vue";
export default {
components: { Loader },
name: "TestCard",
data() {
return {
questions: [],
loading: true,
index: 0,
checkedAnswers: []
};
},
computed: {
currentQuestion() {
if (this.questions !== []) {
return this.questions[this.index];
}
return null;
},
},
methods: {
async getQuestions() {
this.loading = true;
let response = await fetch("http://localhost:4000/test");
let jsonResponse = await response.json();
// put data on questions property
this.questions = jsonResponse.questions;
this.loading = false;
},
answerClick() {
console.log("answer clicked");
},
chooseQuestion(index) {
this.index = index;
},
nextQuestion() {
this.index += 1;
console.log("next question")
}
},
mounted() {
this.getQuestions();
},
directives: {
dragscroll,
},
};
</script>
After that, I would like to check if answers are correct when user presses on "End". How do I connect each checkbox to it's answer and question, then check it if its correct? I have "correct: true" in JSON for each correct answer :)
Thank you
Without changing too much of your existing code you could go about mapping your answers to questions like this. No need for Vuex or more complexity.
<template>
...
<ul>
<li
v-for="( answer, key ) in currentQuestion.answers"
:index="currentQuestion.key"
:key="answer.title"
>
// we pass the key to answerClick to be able to map the answer to the current question
<input v-model="checkedAnswers[key]" #change="answerClick(key)" :id="answer.title" type="checkbox" />
<label :for="answer.title" >{{ answer.title }}</label>
</li>
{{ checkedAnswers }}
...
</template>
</template>
<script>
export default {
name: "TestCard",
data() {
return {
questions: [],
loading: true,
index: 0,
checkedAnswers: [],
answers: []
};
},
computed: {
currentQuestion() {
if (this.questions !== []) {
return this.questions[this.index];
}
return null;
}
},
methods: {
async getQuestions() {
this.loading = true;
let response = await fetch("http://localhost:4000/test");
let jsonResponse = await response.json();
// put data on questions property
this.questions = jsonResponse.questions;
this.loading = false;
},
answerClick(key) {
console.log("answer clicked");
if (!this.answers[this.index]) this.answers[this.index] = [] // if the current question has no answers mapped yet set an empty array
this.answers[this.index][key] = this.checkedAnswers[key]; // set the answer to whatever value it has currently (true, false)
},
chooseQuestion(index) {
this.index = index;
this.checkedAnswers = this.answers[this.index] ? this.answers[this.index] : []; // set the checkedAnswers to what we can find in our mapping, if there is nothing to find use an empty array
},
nextQuestion() {
this.index += 1;
this.checkedAnswers = []; // unset the checked answers for the next question
console.log("next question")
}
},
mounted() {
this.getQuestions();
},
};

Vue js: How to hide button

i'm new to Vue js in this code below , i wanted to hide button "Clear Filter" when nothing selected and show the button only when function " selectedAnswer(index)" called so that it will show only when filter applied otherwise it should be hided , is there a way to do it in my code?
and thanks in advance
<template>
<div class="container" width=800px>
<b-row>
<b-col cols="8">
<h1> Recently Asked </h1>
<ul class="container-question" v-for="(question1,index) in questions" :key="index">
<li>
{{question1.question}}
</li>
</ul>
</b-col>
<b-button class="outline-primaryy" style="margin:auto;" #click="ClearFilter" >Clear Filter</b-button>
</div>
<router-view />
</div>
</template>
<script>
export default {
data() {
return {
questions: [],
answered: null,
index: 0,
selectedIndex: null,
}
},
methods: {
selectedAnswer(index) {
this.selectedIndex = index;
this.questions = this.questions.filter((question) => question.incorrect_answers.includes(index))
console.log(index)
},
ClearFilter() {
this.questions = this.unmutated
},
watch: {
question1: {
handler() {
this.selectedIndex = null;
this.answered = false;
},
},
},
},
mounted: function() {
fetch('https://opentdb.com/api.php?amount=10&category=9&difficulty=medium&type=multiple', {
method: 'get'
})
.then((response) => {
return response.json()
})
.then((jsonData) => {
this.questions = jsonData.results
this.unmutated = jsonData.results;
})
}
}
</script>
You just need to add a v-if="selectedIndex" to your btn element.
ie
<b-button v-if="selectedIndex" class="outline-primaryy" style="margin:auto;" #click="ClearFilter" >Clear Filter</b-button

Click-and-edit text input with Vue

I'm looking for a click-and-edit Vue component.
I've found a fiddle and made some edits. It works like this:
The fiddle is here.
The problem: I need an additional click to make the input focused. How can I make it focused automatically?
The code from the fiddle. HTML:
<div id="app">
Click the values to edit!
<ul class="todo-list">
<li v-for = "todo in todos">
<input v-if = "todo.edit" v-model = "todo.title"
#blur= "todo.edit = false; $emit('update')"
#keyup.enter = "todo.edit=false; $emit('update')">
<div v-else>
<label #click = "todo.edit = true;"> {{todo.title}} </label>
</div>
</li>
</ul>
</div>
JS:
new Vue({
el: '#app',
data: {
todos: [{'title':'one value','edit':false},
{'title':'one value','edit':false},
{'title':'otro titulo','edit':false}],
editedTodo: null,
message: 'Hello Vue.js!'
},
methods: {
editTodo: function(todo) {
this.editedTodo = todo;
},
}
})
You can use a directive, for example
JS
new Vue({
el: '#app',
data: {
todos: [
{ title: 'one value', edit: false },
{ title: 'one value', edit: false },
{ title: 'otro titulo', edit: false }
],
editedTodo: null,
message: 'Hello Vue.js!'
},
methods: {
editTodo: function (todo) {
this.editedTodo = todo
}
},
directives: {
focus: {
inserted (el) {
el.focus()
}
}
}
})
HTML
<div id="app">
Click the values to edit!
<ul class="todo-list">
<li v-for="todo in todos">
<input
v-if="todo.edit"
v-model="todo.title"
#blur="todo.edit = false; $emit('update')"
#keyup.enter="todo.edit=false; $emit('update')"
v-focus
>
<div v-else>
<label #click="todo.edit = true;"> {{todo.title}} </label>
</div>
</li>
</ul>
</div>
You can find more info here
https://v2.vuejs.org/v2/guide/custom-directive.html
With #AitorDB's help I have written a Vue component for this, I call it Click-to-Edit. It is ready to use, so I'm posting it.
What it does:
Supports v-model
Saves changes on clicking elsewhere and on pressing Enter
ClickToEdit.vue: (vue 2.x)
<template>
<div>
<input type="text"
v-if="edit"
:value="valueLocal"
#blur.native="valueLocal = $event.target.value; edit = false; $emit('input', valueLocal);"
#keyup.enter.native="valueLocal = $event.target.value; edit = false; $emit('input', valueLocal);"
v-focus=""
/>
<p v-else="" #click="edit = true;">
{{valueLocal}}
</p>
</div>
</template>
<script>
export default {
props: ['value'],
data () {
return {
edit: false,
valueLocal: this.value
}
},
watch: {
value: function() {
this.valueLocal = this.value;
}
},
directives: {
focus: {
inserted (el) {
el.focus()
}
}
}
}
</script>
Edit for 3.x: [Breaking changes between 2.x and 3.x]
remove .native from the event handlers
change the focus hook to mounted as described in Custom Directives 3.x.
Built on #Masen Furer's work. I added some protection to handle when a user deletes all of the data. There is probably a way to accomplish this using "update" but I couldn't get it working.
I also added the ability to hit escape and abandon any changes.
<template>
<span>
<input type="text"
v-if="edit"
:value="valueLocal"
#blur="save($event);"
#keyup.enter="save($event);"
#keyup.esc="esc($event);"
v-focus=""/>
<span v-else #click="edit = true;">
{{valueLocal}}
</span>
</span>
</template>
<script>
export default {
props: ['value'],
data () {
return {
edit: false,
valueLocal: this.value,
oldValue: (' ' + this.value).slice(1)
}
},
methods: {
save(event){
if(event.target.value){
this.valueLocal = event.target.value;
this.edit = false;
this.$emit('input', this.valueLocal);
}
},
esc(event){
this.valueLocal = this.oldValue;
event.target.value = this.oldValue;
this.edit = false;
this.$emit('input', this.valueLocal);
}
},
watch: {
value: function() {
this.valueLocal = this.value;
}
},
directives: {
focus: {
inserted (el) {
el.focus()
}
}
}
}
</script>
