Vue/Nuxt app is rendering content (not components, just content) twice on every page

I am very new to Vue/Nuxt programming and followed a "add a blog" tutorial which I then modified for my site. It all works perfectly except the actual it is rendering content twice. It renders
NavPage (component) > content > FooterDiv(component) then content again. See image:
Image of the page showing duplicated content
This happens on every page.
I am including my blogpage code ecasue in testing it seems to be where the problem lives :
<template>
<div>
<div class="home-page">
<h2>Latest Posts</h2>
<div class="articles">
<div class="article" v-for="article of articles" :key="article.slug">
<nuxt-link :to="{ name: 'slug', params: { slug: article.slug } }">
<div class="article-inner">
<img :src="require(`~/assets/resources/${article.img}`)" alt="" />
<div class="detail">
<h3>{{ article.title }}</h3>
<p>{{ article.description }}</p>
</div>
</div>
</nuxt-link>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
name: "BlogPage",
data() {
return {
name: ''
}
},
mounted() {
let user = localStorage.getItem('user-info');
if (!user) {
this.$router.push({ name: "BlogPage" })
}
},
async asyncData({ $content, params }) {
const articles = await $content('articles', params.slug)
.only(['title', 'description', 'img', 'slug'])
.sortBy('createdAt', 'asc')
.fetch()
return {
articles
}
}
}
I have also included the structure being rendered by Vue per the Vue Dev Tools
This image is what I see in the dev tools when the page is rendered
I have spent hours troubleshooting this and can find no other info on the issue.
Thank you for any help, and your patience with a newbie. Let me know if you need to see any other code.
As requested here is my NavPage component code:
<template>
<!-- Navigation-->
<nav class="navbar navbar-expand-lg bg-secondary text-uppercase fixed-top" id="mainNav">
<div class="container">
<a class="navbar-brand" href="#page-top">Denise Pedro</a>
<button class="navbar-toggler text-uppercase font-weight-bold bg-primary text-white rounded" type="button" data-bs-toggle="collapse" data-bs-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
Menu
<i class="fas fa-bars"></i>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
<ul class="navbar-nav ms-auto">
<li class="navbar-brand"> <NuxtLink to="/">Home</NuxtLink></li>
<li class="navbar-brand"> <NuxtLink to="/PortfolioPage">Portfolio</NuxtLink></li>
<li class="navbar-brand"> <NuxtLink to="/ResumePage">Resume</NuxtLink></li>
<li class="navbar-brand"> <NuxtLink to="/ContactPage">Contact</NuxtLink></li>
<li class="navbar-brand"> <NuxtLink to="/BlogPage">Blog</NuxtLink></li>
</ul>
</div>
</div>
</nav>
</template>
and my FooterDiv component
<template>
<!-- Footer-->
<footer class="footer text-center">
<div class="container">
<div class="row">
<!-- Footer Location-->
<div class="col-lg-4 mb-5 mb-lg-0">
<h4 class="text-uppercase mb-4">Location</h4>
<p class="lead mb-0">

<br />
</p>
</div>
<!-- Footer Social Icons-->
<div class="col-lg-4 mb-5 mb-lg-0">
<h4 class="text-uppercase mb-4">Around the Web</h4>
<!-- <a class="btn btn-outline-light btn-social mx-1" href="#!"><font-awesome-icon icon="fa-brands fa-facebook" /></a> -->
<a class="btn btn-outline-light btn-social mx-1" href="#!"><img src="../assets/img/facebook-brands.svg" alt="facebook icon" /></a>
<a class="btn btn-outline-light btn-social mx-1" href="#!"><img src="../assets/img/twitter-brands.svg" alt="twitter icon"/></a>

<p class="lead mb-0">

<!-- Start Bootstrap -->
</p>
</div>
</div>
</div>
</footer>
</template>
and lastly, my layout code
<template>
<div>
<NavPage />
<Nuxt />
<FooterDiv />
<Nuxt />
</div>
</template>
<script>
import NavPage from '../src/components/NavPage.vue';
import FooterDiv from '../src/components/FooterDiv.vue'
export default {
components: {
NavPage,
FooterDiv
},
}
</script>
Thank you

In your layout, you've put </Nuxt> twice, that's why the page content is duplicated, you should remove it.
your layout.vue should look like that:
<template>
<div>
<NavPage />
<Nuxt />
<FooterDiv />
</div>
</template>
<script>
import NavPage from '../src/components/NavPage.vue';
import FooterDiv from '../src/components/FooterDiv.vue'
export default {
components: {
NavPage,
FooterDiv
},
}
</script>

V-for iteration ruins the styles

I have a slider which consists of products.
Right now I'm getting a list of products from the server and populating that slider with the result returned from the server. For this I have the following
<div class="most_buy_slider container special_proposal">
<div v-for="product in mostBoughtProducts">
<div>
<div class="goods_item">
<img :src="product.ProductPreviewImages[0]">
<div class="name">
{{product.Name}}
<span>{{product.Manufacturer}}</span>
</div>
<div class="price">{{product.Price}} грн</div>
<div class="economy">економія складає 57% від роздрібної вартості</div>
<div class="to_cart">
<button type="button" class="btn but_blue">в кошик</button>
</div>
</div>
</div>
</div>
</div>
But this result in the following:
however, when I render simple html without v-for it loads correctly.
<div class="most_buy_slider container bigger_width special_proposal">
<div>
<div v-for="index in 10" class="goods_item">
<img src="images/samples/whiskyjackdan.png">
<div class="name">
Вологі серветки Вологі серветки Вологі серветки Вологі серветки
<span>Ruta Selecta Ruta SelectaRuta SelectaRuta Selecta</span>
</div>
<div class="price">
45,55 грн
</div>
<div class="economy">
економія складає 57% від роздрібної вартості
</div>
<div class="to_cart">
<button type="button" class="btn but_blue">в кошик</button>
</div>
</div>
</div>
<div>
<div class="goods_item">
<img src="images/samples/ruta1.png">
<div class="name">
Вологі серветки
<span>Ruta Selecta</span>
</div>
<div class="price">
45,55 грн
</div>
<div class="economy">
економія складає 57% від роздрібної вартості
</div>
<div class="to_cart">
<button type="button" class="btn but_blue">в кошик</button>
</div>
</div>
</div>

I don't know your CSS, but in first code snippet you included you use additional div for v-for directive, that can break your styles.
Try this code instead:
<div class="most_buy_slider container special_proposal">
<div v-for="product in mostBoughtProducts">
<div class="goods_item">
<img :src="product.ProductPreviewImages[0]" />
<div class="name">
{{ product.Name }}
<span>{{ product.Manufacturer }}</span>
</div>
<div class="price">{{ product.Price }} грн</div>
<div class="economy">економія складає 57% від роздрібної вартості</div>
<div class="to_cart">
<button type="button" class="btn but_blue">в кошик</button>
</div>
</div>
</div>
</div>

I finally solved the problem
I was using Slick slider to display items. While data is being loaded from the server, the slick slider already gets initialized with 0 item in it. And when items has been loaded from the server, vue.js inserts data into the slider, but the slider still assumes that it has 0 item.
So the solution is to reinitialize the slick slider when data loaded from the server.
I called the following after the data load:
reInit() {
$('.most_buy_slider').slick('unslick');
$(".most_buy_slider").slick(this.sliderSettings())
}
sliderSettings() {
return {
infinite: true,
slidesToShow: 4,
slidesToScroll: 1
}
}

whats the best way to control showing and hiding multiple charts and divs in a page

I am new in javascript,i have a page consist of different Card layouts and each card has its own chart or buttons or grids,some of them should be hidden by default and some of them should be hide or visible by click,since the page is growing by more demands ,controlling these hid/e/show is becoming a nightmare,i would like you tell me whats the best way to do this?for example i have a following div which has a chart:
<section style="width:100%;margin-top:2%;" >
<div id="btnCurrentStatID" class="card ShowHide" style="float:right;width:20%;height:350px;display:none;">
<div class="wrapper">
<div class="containerBtns" style="width:100%;float:right" >
<button type="button" id="btnErrorStat" class="btnsForCrew-Common "></button>
<button type="button" id="btnIdle" class="btnsForCrew-Common "></button>
<button type="button" id="btnService" class="btnsForCrew-Common "></button>
<button type="button" id="btnLinkDn" class="btnsForCrew-Common"></button>
<button type="button" id="btnDataIn" class="btnsForCrew-Common" ></button>
<button type="button" id="btnrepOff" class="btnsForCrew-Common"></button>
</div>
</div>
</div>
<div id="faultStatChartID" class="card ShowHide" >
<div id="chart">
</div>
</div>
<div id="pieChartID" class="card ShowHide">
<div id="pieChart"></div>
</div>
</section>
<section style="width:100%;float:left;margin-top:3%;" id="faultStatSubGroupsSec">
<div id="subcatNameChartSectionID" class="card" style="width:49%;float:left;display:none">
<div class="container">
<div id="subcatNameChart"></div>
</div>
</div>
<div id="subcatErrorChartSectionID" class="card" style="width:49%;float:right;display:none">
<div class="container">
<div id="subcatErrorChart"></div>
</div>
</div>
<div id="subCatIdnameSectionID" class="card" style="width:49%;float:left;display:none">
<div class="container">
<div id="subCatIdname"></div>
</div>
</div>
<div id="subCatITurNameSectionID" class="card"style="width:49%;float:right;display:none">
<div class="container">
<div id="subCatITurName"></div>
</div>
</div>
<div></div>
<div></div>
</section>
i gave it showhide class,and by default its hidden,when i click on filter button it will be visible,and other divs should be hidden,it this continues,imagine how many time i should do it and manage to control them all,
$(".ShowHide").css("display", "block");
$("#subcatNameChartSectionID").hide();
$("#subcatErrorChartSectionID").hide();
$("#subCatIdnameSectionID").hide();
$("#subCatITurNameSectionID").hide();

A way would be to use a class for hiding.
.hide {
display: none;
}
And a hideable class for accessing every item that should be able to be hidden. The class hide can be added to hide the element.
<div class="hideable">1 hideable</div>
jQuery offers methods for class manipulation:
$('.hideable').toggleClass('hide');
$('#unique4').removeClass('hide');
$('#unique5').addClass('hide');
Here is the full snippet code:
$('.hideable').toggleClass('hide');
$('#unique4').removeClass('hide');
$('#unique5').addClass('hide');
.hide {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="unique1" class="hideable">
1 hideable
</div>
<div id="unique2" class="hideable">
2 hideable
</div>
<div id="unique3" class="hideable hide">
3 hideable
</div>
<div id="unique4" class="hideable hide">
4 hideable
</div>
<div id="unique5" class="hide">
5 other
</div>

Rendering with reactjs

I am creating a sample app using reactjs. I am very new in reactjs. I set up all the things for reactjs like
1) Babel
2)Webpack
Using webpack I am genrating a file code.js which is included in the index file where all the code runs.
I am creating my first page but i got error like:
ERROR in ./components/Login/Login.js
Module build failed: SyntaxError: C:/xampp/htdocs/reactApp/components/Login/Logi
n.js: Expected corresponding JSX closing tag for <img> (18:33)
I dont know why the html rendering gives me error.
My code is like:
import React, {Component} from 'react';
import {Link} from 'react-router'
export default class Home extends Component {
render () {
return (
<div class="page-content container">
<div class="row">
<div class="col-md-4 col-md-offset-4">
<div class="login-wrapper">
<div class="box">
<div class="content-wrap">
<h6>Sign In</h6>
<div class="social">
<a class="face_login" href="#">
<span class="face_icon">
<img src="images/facebook.png" alt="fb">
</span>
<span class="text">Sign in with Facebook</span>
</a>
<div class="division">
<hr class="left">
<span>or</span>
<hr class="right">
</div>
</div>
<input class="form-control" type="text" placeholder="E-mail address">
<input class="form-control" type="password" placeholder="Password">
<div class="action">
<a class="btn btn-primary signup" href="index.html">Login</a>
</div>
</div>
</div>
<div class="already">
<p>Dont have an account yet?</p>
Sign Up
</div>
</div>
</div>
</div>
</div>
)
}
}
Please help me to solve this problem

There is at least one more problem: You used class= instead of className= everywhere. Obviously you did try to copy & paste html code. There is a great online converter which i use. It allows you to do that without errors: http://magic.reactjs.net/htmltojsx.htm
import React, {Component} from 'react';
import {Link} from 'react-router'
export default class Home extends Component {
render () {
return (
<div className="page-content container">
<div className="row">
<div className="col-md-4 col-md-offset-4">
<div className="login-wrapper">
<div className="box">
<div className="content-wrap">
<h6>Sign In</h6>
<div className="social">
<a className="face_login" href="#">
<span className="face_icon">
<img src="images/facebook.png" alt="fb" />
</span>
<span className="text">Sign in with Facebook</span>
</a>
<div className="division">
<hr className="left" />
<span>or</span>
<hr className="right" />
</div>
</div>
<input className="form-control" type="text" placeholder="E-mail address" />
<input className="form-control" type="password" placeholder="Password" />
<div className="action">
<a className="btn btn-primary signup" href="index.html">Login</a>
</div>
</div>
</div>
<div className="already">
<p>Dont have an account yet?</p>
Sign Up
</div>
</div>
</div>
</div>
</div>
)
}
}
Hope you found this useful.

The error clearly mentions what needs to be done. In JSX you need to close the singleton tags like <br> , <img> and <input>
import React, {Component} from 'react';
import {Link} from 'react-router'
export default class Home extends Component {
render () {
return (
<div class="page-content container">
<div class="row">
<div class="col-md-4 col-md-offset-4">
<div class="login-wrapper">
<div class="box">
<div class="content-wrap">
<h6>Sign In</h6>
<div class="social">
<a class="face_login" href="#">
<span class="face_icon">
<img src="images/facebook.png" alt="fb" />
</span>
<span class="text">Sign in with Facebook</span>
</a>
<div class="division">
<hr class="left">
<span>or</span>
<hr class="right">
</div>
</div>
<input class="form-control" type="text" placeholder="E-mail address" />
<input class="form-control" type="password" placeholder="Password" />
<div class="action">
<a class="btn btn-primary signup" href="index.html">Login</a>
</div>
</div>
</div>
<div class="already">
<p>Dont have an account yet?</p>
Sign Up
</div>
</div>
</div>
</div>
</div>
)
}
}

Drawing rectangles with Jquery

I have a div called #llens where I need to draw some boxes ( div's). I can't understand why is not drawing. I'm a litle newbie so please be patient if I'm make a great mistakes :P
that's the div :
<div id="estructura" class="collapse ">
<section data-toggle="buttons-radio" class="btn-group btn-group-vertical">
<header id="professor" class="btn btn-primary boto_funcio ">
<h2>Professors</h2>
</header>
<header id="alumne" class="btn btn-primary boto_funcio ">
<h2>Alumnes </h2>
</header>
<header id="text" class="btn btn-primary boto_funcio ">
<h2>Text </h2>
</header>
</section>
</div>
<section class="span9">
<div id="llens"></div>
<!-- llens -->
</section>
Here is the example : http://jsfiddle.net/blackersoul/PLWkS/
I 've done a fork from the code there : http://jsfiddle.net/lollero/kDmqw/

Sometimes a html element is not displayed when it is empty. Try <div id="llens"> </div>.
