Currently i have been using this code in the inline CDN version of VueJS and it works fine, but when i add this to gridsome the click event on the animation to open the slide out doesn't work.
I have looked up that animations for page enter is working but i am not sure how to handle component animations.
Are animations working in Gridsome?

Got the data part wrong, animations do work!

Trying to implement the overlay fullscreen menu with Vue.js, html/css/js is [this solution]https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_overlay2
But stuck with how to toggle div height from 0% to 100%. I did create 2 classes,
'navbar'
'navbar_open'
but I am not sure how to toggle between them in Vue. I could see that once #click triggered, the class="navbar navbar_open"
<div id="myNav" class="navbar navbar_open">
<div class="closebtn">
<i class="fa fa-times"></i>
</div>
<div class="navbar-content">
<a>Home</a><a>Contact</a>
</div>
</div>
below is the App.vue file,
<template>
<div id="app">
<!-- Banner/Header -->
<!-- Hamburger -->
<div id="myNav" class="navbar" :class="{ navbar_open: showNavbar }">
<div class="closebtn" v-on:click="showNavbar = !showNavbar">
<i class="fa fa-times"></i>
</div>
<div class="navbar-content">
<a>Home</a>
<a>Contact</a>
</div>
</div>
<div class="openbtn">
<i class="fa fa-bars" v-on:click="showNavbar = !showNavbar"></i>

<router-view />
</div>
</template>
<script>
export default {
data() {
return {
showNavbar: false
};
},
methods: {
toggleNavbar() {
this.showNavbar = !showNavbar;
},
setHeightValue(showNavbar) {
const heightValue = this.showNavbar ? '100%' : '0%';
return heightValue;
}
},
created() {
this.setHeightValue();
}
};
</script>

I see that you have unused method toggleNavbar. You call setHeightValue only when your component is created and then never again (I think you can remove this method). This menu is not 100% height probably because you embedded this component in another container (<div id="app:...) which has smaller height so height: 100% will be 100% height of parent container. Instead of 100% you can use 100vh (vh - is a viewport unit and it will always take 100% viewport height [if 50vh then 50% of total viewport height]). You should also apply only navbar_open but now you are applying bot classes if your navbar is open: navabar navbar_open so you should add this classes conditionally:
:class="{ 'navbar_open': showNavbar, 'navbar': !showNavbar }"
You have also Two different buttons responsible for two different actions:
closebtn -> close navigation
openbtn -> open navigation
So you should create two different methods openNavigation closeNavigation
<div id="app">
<!-- Banner/Header -->
<!-- Hamburger -->
<div id="myNav" :class="{ 'navbar_open': showNavbar, 'navbar': !showNavbar }">
<div class="closebtn" #click="closeNavigation">
<i class="fa fa-times"></i>
</div>
<div class="navbar-content">
<a>Home</a>
<a>Contact</a>
</div>
</div>
<div class="openbtn">
<i class="fa fa-bars" #click="showNavigation"></i>
</div>
<router-view />
</div>
</template>
<script>
export default {
data() {
return {
showNavbar: false
};
},
methods: {
openNavigation() {
this.showNavbar = true;
},
closeNaviagation() {
this.showNavbar = false;
}
}
};
</script>
<style>
...
.navbar_open {
width: 100%;
height: 100vh; // <--- 100vh instead of 100%
position: fixed;
...
</style>
I don't know if what I want is possible in the way I want to do it. I'm using this Vue plugin for modals: https://www.npmjs.com/package/vue-js-modal
I have a component called ModalButton that is responsible for triggering the modal:
<modal-button :modal-data="{{ collect(['account' => $account]) }}" modal-name="leave-account">Leave Account</modal-button>
As you can see, I'm sending :modal-data as props.
The ModalButton component is the following:
<template>
<button #click.prevent="show" type="button" class="px-3 py-2 bg-gray-200 font-bold text-gray-700 ">
<slot></slot>
</button>
</template>
<script>
// # is an alias to /src
export default {
name: 'ModalButton',
data() {
return {
}
},
props: {
modalName: String,
modalData: Object
},
methods: {
show () {
this.$modal.show(this.modalName, this.modalData);
},
hide () {
this.$modal.hide(this.modalName);
}
}
}
</script>
You can see on the show method which comes from the plugin is sending that data to the modal
this.$modal.show(this.modalName, this.modalData);
In my blade template (i'm using laravel), I have the <modal>:
<modal name="leave-account" class="text-center">
<div class="flex items-center justify-center h-full p-6">
<div>
<div>
<div class="text-3xl font-bold mb-2">Are you sure?</div>
<p>If you leave this account, you won't be able to join back unless invited again. </p>
</div>
<footer class="flex items-center justify-end mb-24 mt-auto">
<button class="px-3 py-2 bg-gray-200 font-bold text-gray-700 mr-3">Cancel</button>
<ajax-button
class-list="px-3 py-2 bg-primary text-white font-bold"
:route=#{{SOMEHOW ACCESS MODAL DATA}}
method="delete">
Yes, leave account
</ajax-button>
</footer>
</div>
</div>
</modal>
Inside my modal, I have another component called AjaxButton which allows me to have a reusable button that handles ajax requests.
I need a way of accessing the modal data that was passed to the modal. I'd like not to have to create an additional specific modal component to handle this.
Is this possible?
Specifically what the :route prop needs to send is the Account since my route requires model binding. i.e it'll look something like /accounts/leave/53
Edit:
So I can do this:
<button #click="$modal.hide('leave-account')" class="px-3 py-2 bg-gray-200 font-bold text-gray-700 mr-3">Cancel</button>
(that's right above my <ajax-button>)
So clearly I'm able to access the $modal properties / methods. So there has to be a way to accomplish what I want
You can use a simpler modal:
<modal-button v-model="showModal">
Leave Account
</modal-button>
<modal v-model="showModal" caption="Leave Account">
{{ collect(['account' => $account]) }}
</modal>
Then modal-button will look like this:
<template>
<button #click.stop="$emit('input',true)" type="button" class="px-3 py-2 bg-gray-200 font-bold text-gray-700 ">
<slot/>
</button>
</template>
<script>
export default
{
name: 'ModalButton',
props:
{
value:
{
type: Boolean,
default: false
}
}
}
</script>
and the modal component will be:
<template>
<transition name="modal">
<div class="modal_overlay" #click="close" v-if="value">
<div class="modal_content" style="overflow: auto;" #click.stop>
<div class="modal_title">{{ caption }} <div class="modal_close" #click="close">✖</div></div>
<slot/>
</div>
</div>
</transition>
</template>
<script>
export default
{
props:
{
value:
{
type: Boolean,
default: false
},
caption:
{
type: String,
default: ''
},
created()
{
document.addEventListener('keydown', this.modal_escape, false);
},
beforeDestroy()
{
document.removeEventListener('keydown', this.modal_escape, false);
},
methods:
{
close()
{
this.$emit('input', false);
},
modal_escape(event)
{
var e = event || window.event;
if(this.value && e.keyCode == 27)
{
this.close();
// All good browsers…
if (e.preventDefault) e.preventDefault();
// …and IE
if (e.returnValue) e.returnValue = false;
return false;
}
}
}
}

I've read through innumerable posts about how to do this with jquery, but Vue.js jealously owns and manages the dom, so I will need a solution that uses standard Vue.js components or libraries.
Thus far, I've located several examples that are what I'd call 'button-event-driven' solutions, but I will need to programmatically handle open and close of the modal.
Problem / Design Requirement: When a public user attempts to interact with a tempting button or other function on my application, and they are not yet logged in, I wish to programmatically launch a modal dialogue to then ask them to log in.
Once successfully, I'll need to programmatically close the same dialogue modal. Or, of course, they can choose to cancel and continue browsing as a public user without the ability to do those functions.
Other Helpful Information: I'm using bootstrap 4.4.1
You can use a watch property. If a user is not logged in as login=false then the modal shows.
// register modal component
Vue.component("modal", {
template: "#modal-template"
});
// start app
new Vue({
el: "#app",
data: {
showModal: false,
login: null
},
created() {
this.login = false;
},
watch: {
"login": function(val) {
this.showModal = !val;
}
}
});

The appearance of the view and its component is pretty rough and without much formatting, but you get the picture.
Hopefully this helps somebody else if they're looking for a straight-forward modal in Vue; I believe it has to be a very common design requirement, and this approach worked for me.
The simple solution is:
add a reference to modal component
<share-modal ref="share-modal-ref"/>
import Modal like this:
import { Modal } from 'bootstrap'
then in your method do this:
let element = this.$refs.listModal.$el
let shareModal = new Modal(element, {})
shareModal.show()
It works on Vue 3 & Boostrap 5
Default the loading image is true after complete the upload loading image is false, but after update the loading object no effect in view, always show the loading bar.

You update isloadingImage array's values using its keys. In such a case for the change to be reactive, you need to replace your whole array after the fact.
Example:
axios.post('http://localhost:800/uploadimage', myFormData)
.then(response => {
this.isloadingImage[key] = false;
this.isloadingImage = this.isloadingImage.slice(0);
// ^^^ this line
}).catch(error=> {
console.log('error', key, error)
this.isloadingImage[key] = false;
this.isloadingImage = this.isloadingImage.slice(0);
// ^^^ and line
});
Use data as function, not as object like you do.
new Vue({
el:"#app",
data () {
return {
imageIsLoading: ...
I'm trying to integrate the Accordion component with a body transition, but without success :( . All is working as well except the animation.
template:
<div class="accordion">
<div class="accordion-title" #click="isOpen = !isOpen" :class="{'is-open': isOpen}">
<span>{{title}}</span>
<i class="ic ic-next"></i>
</div>
<div class="accordion-body" :class="{'is-open': isOpen}">
<div class="card">
<slot name="body"></slot>
</div>
</div>
</div>
component:
props: {
title: {
type: String,
default: 'Title'
}
},
data() {
return {
isOpen: false
}
}
And styles:
.accordion-body {
font-size: 1.3rem;
padding: 0 16px;
transition: .3s cubic-bezier(.25,.8,.5,1);
&:not(.is-open) {
display: none;
height: 0;
overflow: hidden;
}
&.is-open {
height: auto;
// display: block;
padding: 16px;
}
}
.card {
height: auto;
}
I tried to use <transition> but it doesn't work with height or display properties.
Help please!
display:none will remove your content and avoid the animation, you should trick with opacity, overflow:hidden and height, but you ll be forced to do a method for that.
For example (not tested, but inspiring):
in template:
<div class="accordion" #click="switchAccordion" :class="{'is-open': isOpen}">
<div class="accordion-title">
<span>{{title}}</span>
<i class="ic ic-next"></i>
</div>
<div class="accordion-body">
<p></p>
</div>
</div>
in component (add a method):
methods: {
switchAccordion: function (event) {
let el = event.target
this.isOpen = !this.isOpen // switch data isOpen
if(this.isOpen) {
let childEl1 = el.childNodes[1]
el.style.height = childEl1.style.height
} else {
let childEl2 = el.childNodes[2]
el.style.height = childE2.style.height // or .clientHeight + "px"
}
}
}
in style:
.accordion {
transition: all .3s cubic-bezier(.25,.8,.5,1);
}
.accordion-body {
font-size: 1.3rem;
padding: 0 16px;
opacity:0
}
.is-open .accordion-body {
opacity:0
}
In this case, your transition should work as you want.
The javascript will change the height value and transition transition: all .3s cubic-bezier(.25,.8,.5,1); will do the animation
