Vue.js changes data values by itself - vue.js

This might sound really strange, but it seems Vue decided to change data values by itself. I have a component :is="currentView" tag. I initially set the currentView data to loading and then change it to authenticate later if a condition is met. This works fine. But when a use has authenticated and I change currentView to loading while authenticating the user, it loads for 0.1 seconds and then shows the authenticate component and does that once more, then it shows the component that it should after authenticating. If I log currentView after setting it to loading it logs authenticate and then loading with around 100 milliseconds in between. I can guarantee that I never set currentView to authenticate by myself.
I'm using Nuxt if that matters.
index.vue:
<template>
<div class="container">
<div class="card">
<div class="card-header">

<div class="card-block text-center">

Any ideas?
EDIT: Fixed by moving loading component to the Authenticate component and emit an even when the user is authenticated. Still don't know the "real" solution to this though.
EDIT 2: After some testing it was still not working properly. Creating a new project with the webpack template and copying over code made it work perfectly.

How to get route name in vueJS

I am trying to create a script in vueJS, to enable the navbar only when the pages are not login/register.
For this I am trying to use this.$route.name but I only get undefined in the console when I am console logging it. I have created a method to check for the route name and i am calling it when the components are mounted i.e using mounted fucntion.
app.vue code:
<template>
<div id="app">
<NavBar v-if="flag" />
<main>
<router-view/>
</main>
</div>
</template>
<script>
import NavBar from './components/NavBar.vue';
export default {
components: { NavBar },
data(){
return{
flag1 : false,
flag2 : false,
flag: false
}
},
mounted() {
let id = localStorage.id;
this.getrouteflags();
return {
id
}
},
methods : {
getrouteflags: function(){
console.log(this.$route.query.name)
if(this.$route.name == 'register'){
this.flag1 = true;
}
if(this.$route.name == 'login'){
this.flag2 = true;
}
this.flag = this.flag1 || this.flag2;
console.log(this.flag1,this.flag2)
}
}
}
</script>
<style>
nav{

#app{
width: 100%;

padding: 0;
margin: 0;
min-height: 100vh;
width: 100%;
}
html{
background-color: white;
}
</style>
This is what I am getting in the console.
Can someone help me in resolving this issue?
I'm guessing you're using Vue2.
Have you tried adding a computed property:
computed: {
currentRouteName() {
return this.$route.name;
}
}
In case you're using Vue3 with a script setup you could use VueRouter's composable.
<script setup>
import { useRouter, useRoute } from 'vue-router';
const router = useRouter();
const route = useRoute();
// Do stuff.
</script>
If you need more help, read VueRouter's guide.

Animate width of div bound to data property in Vue

I have this progress bar div, whichs width is bound to the data property result and changes accordingly. At the moment it still jumps, but I want to animate it. I thought of tracking the old and the new Value and injecting it in the css with css variables or just using a setInterval method, but tracking the 2 values seems to get quite complicated and it seemed like a overkill for me. Does anyone have an easier idea?
<template>
<div class="progress">
<div class="progress-value" :style="{ 'width': result + '%' }">
<h2>{{ result }}%</h2>
</div>
</div>
</template>
<script>
export default {
props: ["result"],
};
</script>
<style scoped>
.progress {
background: #ccc;
border-radius: 100px;
position: relative;
padding: 5px 5px;
margin: 5px 5px;
height: 40px;
width: auto;
}
.progress-value {
animation: load 3s normal forwards;
border-radius: 100px;
background: #fff;
height: 30px;
text-align: center;
}
/* #keyframes load {
0% {
width:
}
100% {
width:
}
} */
</style>
Add css transition like this:
transition-property: all;
transition-timing-function: cubic-bezier(0.4, 0, 0.2, 1);
transition-duration: 1s;
And fix the binding:
<div class="progress-value" :style="'width: ' + result + '%'">
See this example
<template>
<div class="progress">
<div class="progress-value" :style="'width: ' + result + '%'">
<h2>{{ result }}%</h2>
</div>
</div>
</template>
<script>
export default {
data () {
return {
result: 5
}
},
mounted() {
this.increment()
},
methods: {
increment() {
this.result += 10
if (this.result < 95) {
setTimeout(this.increment, 1000)
}
}
}
}
</script>
<style scoped>
.progress {
background: #ccc;
border-radius: 100px;
position: relative;
padding: 5px 5px;
margin: 5px 5px;
height: 40px;
width: auto;
}
.progress-value {
transition-property: all;
transition-timing-function: cubic-bezier(0.4, 0, 0.2, 1);
transition-duration: 1s;
background: #fff;
height: 30px;
text-align: center;
}
</style>

font-size: 40px;
top: 15px;

}
}
Javscript
<script>
import { mapGetters } from "vuex"
export default {
computed: mapGetters({ isLoggedIn: 'CheckAuth', items: 'GetItems' }),
data() {
return {
clipped: true,
drawer: true,
fixed: false,
miniVariant: true,
right: true,
rightDrawer: false,
title: 'Vuetify.js'
}
},
methods: {
Login() {
this.$store.dispatch('ChangeAuth');
},
OpenDialog() {
document.getElementById("myNav").style.width = "100%";
},
CloseDialog() {
document.getElementById("myNav").style.width = "0%";
}
}
}
</script>
This is a pure CSS issue. You can either add :after pseudo element and create the background with it. Or you can use pointer-events: none;
CSS property on the overlay element.

How to integrate jsplumb in vuejs?

I have tried jsplumb script in .html file under the script tag. This is working fine.
<body>
<div id="q-app"></div>
<!-- built files will be auto injected -->
<script>
jsPlumb.ready(function() {
jsPlumb.connect({
source:"item_left",
target:"item_right",
endpoint:"Rectangle"
});
jsPlumb.draggable("item_left");
jsPlumb.draggable("item_right");
});
</script>
</body>
But now i want to integrate this jsplumb code/script in .vue file.I tried to put this script in .vue file under script tag, but i did not get any output except an blank page with zero errors. How can i proceed further?.Guide me with some simple example.
You can try this:
mydraggableview.vue
<template>
<div id="diagramContainer">
<div id="item_left" class="item"></div>
<div id="item_right" class="item" style="margin-left:50px;"></div>
</div>
</template>
<script>
import jsplumb from 'jsplumb'
export default {
props: ['yourProps'],
data() {
return {
your: data
}
},
mounted(){
jsPlumb.ready(function() {
jsPlumb.connect({
source:"item_left",
target:"item_right",
endpoint:"Rectangle"
})
})
}
}
</script>
Then you can import where you are going to use it.
otherfile.js
<script>
import myDraggableComponent from './path/to/component/mydraggableview'
</script>
and use it as directive or inside your component.
I managed to put together working code based on jsplumb demo community example -
<template>
<div id="canvas" class="jtk-demo-canvas canvas-wide flowchart-demo jtk-surface jtk-surface-nopan">
<div id="flowchartWindow1" class="window jtk-node">1</div>
<div id="flowchartWindow2" class="window jtk-node">2</div>
<div id="flowchartWindow3" class="window jtk-node">3</div>

Simple Gallery Slider

I'm trying to create a simple slider using divs and javascript. I set up a div with six images and an arrow that movies the containder holding the images 528px (the width of each image) every time it's clicked. When I reach the begining or end of the gallery, I want the respective arrow button to fade out so that the user won't keep pressing next/prev.
Any help is appreciated.
JAVASCRIPT
$("#btn-gallery-next").click(function(){
$("div#gallery li").not(this).removeClass('clicked');
$("div#gallery-slide").animate({left:"-=528px"});
if($("div#gallery-slide").position().left < -3168)
{
$("#btn-gallery-next").fadeOut();
}
else {
$("#btn-gallery-next").fadeIn();
}
});
$("#btn-gallery-prev").click(function(){
$("div#gallery li").not(this).removeClass('clicked');
$("div#gallery-slide").animate({left:"+=528px"});
if($("div#gallery-slide").position().left > 0)
{
$("#btn-gallery-prev").fadeOut();
}
else {
$("#btn-gallery-prev").fadeIn();
}
});
HTML
<div id="gallery-slide">
<img class="gallery-img" src="_/img/gallery/img1.jpg" alt="" />
<img class="gallery-img" src="_/img/gallery/img2.jpg" alt="" />
<img class="gallery-img" src="_/img/gallery/img3.jpg" alt="" />
<img class="gallery-img" src="_/img/gallery/img4.jpg" alt="" />
<img class="gallery-img" src="_/img/gallery/img5.jpg" alt="" />
<img class="gallery-img" src="_/img/gallery/img6.jpg" alt="" />
</div>
Try flex slider from woothemes, it have all ur needs.
Why not use a slider library like Owl Slider? It comes with lots of options and configurations. It is super simple to integrate into any project.
Example #1 www.midwestgathering.com/#galleries
Example #2 www.owlgraphic.com/owlcarousel/demos/images.html
Another option is jcarousel. The basic slider is shown with an example that makes the left next button inactive until the user slides to the right, then once the user gets to the end of the gallery the right next button becomes inactive:
JS
(function($) {
$(function() {
$('.jcarousel').jcarousel();
$('.jcarousel-control-prev')
.on('jcarouselcontrol:active', function() {
$(this).removeClass('inactive');
})
.on('jcarouselcontrol:inactive', function() {
$(this).addClass('inactive');
})
.jcarouselControl({
target: '-=1'
});
$('.jcarousel-control-next')
.on('jcarouselcontrol:active', function() {
$(this).removeClass('inactive');
})
.on('jcarouselcontrol:inactive', function() {
$(this).addClass('inactive');
})
.jcarouselControl({
target: '+=1'
});
$('.jcarousel-pagination')
.on('jcarouselpagination:active', 'a', function() {
$(this).addClass('active');
})
.on('jcarouselpagination:inactive', 'a', function() {
$(this).removeClass('active');
})
.jcarouselPagination();
});
})(jQuery);
