I'm working with Vuejs and Nuxt and would like to display a video in a carousel component along side jpeg and png images . The carousel component:
<template>
<section>
<v-card
class="mx-auto"
color="#26c6da"
dark
max-width="1200"
>
<v-carousel>
<v-carousel-item v-for="(item,i) in items" :key="i" :src="item.src"></v-carousel-item>
</v-carousel>
</v-card>
</section>
<script>
export default {
data() {
return {
items: [ {
id: '1',
content: '<iframe width="560" height="315" ' +
'src="https://www.youtube.com/embed/zjcVPZCG4sM" ' +
'frameborder="0" allow="autoplay; encrypted-media" ' +
'allowfullscreen></iframe>'
},
{
src: "https://cdn.vuetifyjs.com/images/carousel/sky.jpg"
},
{
src: "https://cdn.vuetifyjs.com/images/carousel/bird.jpg"
},
{
src: "https://cdn.vuetifyjs.com/images/carousel/planet.jpg"
}
]
};
}
};
</script>
</template>
Based on The answer Displaying video in Nuxt carousel component and https://codepen.io/anon/pen/MqBEqb
I need:
<v-carousel-item v-for="item in items" :key="item.id" v-html="item.content">
for a video and
<v-carousel-item v-for="(item,i) in items" :key="i" :src="item.src"></v-carousel-item>
for a jpg. How do I dynamically add 1 or the other based on the object in the exported data array?
You can use v-for on the template and later use v-if to do the check and insert one or the other as demonstrated here.
https://vuejs.org/v2/guide/list.html#v-for-on-a-lt-template-gt
https://codepen.io/autumnwoodberry/pen/qXGjXY?editors=1010
There is a trick by which you can implement your use-case. You can use the combination of both v-if and v-for. I did put condition based on either it is content or src. Additionally, I have added id attribute for all the data items. Here is the working link for the codepen https://codepen.io/arunredhu/pen/MdebLV
<v-carousel>
<template v-for="item in items" :key="item.id">
<v-carousel-item >
<img v-if="item.src" :src="item.src"/>
<div class="video-elem" v-if="item.content" v-html="item.content"></div>
</v-carousel-item>
</template>
</v-carousel>
You can use template and v-if='item.src'
<div id="app">
<v-app>
<v-content>
<v-container>
<v-carousel>
<template v-for="item in items" :key="item.id">
<v-carousel-item v-if="item.src" :src="item.src"></v-carousel-item>
<v-carousel-item v-else v-html="item.content"></v-carousel-item>
</template>
</v-carousel>
</v-container>
</v-content>
</v-app>
</div>

I use vuetify to make a kind of carousel to display recipes that are stored in the database.
But I would like when I click on a recipe the carousel opens below a space with all the elements of the recipe in question (the one we clicked on) So I found a component on vuetify that corresponds exactly to what I'm looking for: Here is Vuetify Carousel
But in my v-slide-item I use a loop that retrieves the recipe data but suddenly from the v-expand-transition I no longer have access to this loop how can I display the recipe data suddenly?
Here is the code :
<template>
<v-sheet
class="mx-auto"
elevation="8"
max-width="100%"
style="box-shadow: none !important;"
>
<v-slide-group
v-model="model"
class="pa-4 slider"
show-arrows
>
<v-slide-item
v-for="n in Object.keys(recipes)"
:key="recipes[n].id"
v-slot="{ active, toggle }"
>
<v-card
:color=" 'grey lighten-1'"
class="ma-4 card-recipe"
height="200"
width="200"
style="border-radius: 10px;"
v-bind:style="recipes[n].recipe[0].first_recipes_image != null ? { backgroundImage: 'url(' + recipes[n].recipe[0].first_recipes_image + ')' } : { backgroundImage: 'url(https://cdn.vuetifyjs.com/images/cards/sunshine.jpg)' }"
#click="toggle"
>
<p class="card-text" ><span class="black--text">{{ recipes[n].recipe[0].name }}</span></p>
<v-row
class="fill-height"
align="center"
justify="center"
>
<v-scale-transition>
<v-icon
v-if="active"
color="white"
size="48"
v-text="'mdi-close-circle-outline'"
></v-icon>
</v-scale-transition>
</v-row>
</v-card>
</v-slide-item>
</v-slide-group>
<v-expand-transition>
<v-sheet
v-if="model != null"
height="200"
tile
style="background-color: #FFF8F0 !important;"
>
<v-row
class="fill-height"
align="center"
justify="center"
>
<h3 class="text-h6">
Selected {{ model }}
</h3>
</v-row>
</v-sheet>
</v-expand-transition>
</v-sheet>
</template>
<script>
import { mapGetters } from "vuex";
export default {
props: {
},
data: () => ({
model: null,
recipes: [],
openedCards: [],
}),
computed: {
console: () => console,
...mapGetters({
plantActive: 'permatheque/getPlant',
}),
},
methods: {
async getPlantRecipes() {
this.$axios
.$get("/lnk/plant/recipes?plant_id=" + this.plantActive.id + "")
.then((response) => {
this.recipes = response;
console.log(this.recipes);
})
.catch((error) => {
console.log(error);
});
},
},
mounted() {
this.getPlantRecipes()
}
}
</script>
Hope I was clear enough, thanks!
You can use the v-model of the v-slide-group which is basically the index from recipes array of the selected item in the carousel.
This way you know which recipe is selected, so you can go grab the recipe info from the array or make another api call to get that info.
Example
Check this codesandbox I made: https://codesandbox.io/s/stack-71474788-recipes-carousel-6vm97o?file=/src/components/Example.vue
If you already have the recipe info within your recipes array, all you need to do is use the v-model variable of the v-slide-group which I renamed to recipeIndex to access that data directly from your array.
<v-expand-transition>
<v-sheet v-if="recipeIndex != null" tile style="background-color: #FFF3E0 !important;">
<v-container fluid class="pa-12">
<v-row>
<v-col cols="12" sm="6">
<span class="text-h6">{{ `${recipes[recipeIndex].name}'s Recipe` }}</span> <br>
<span class="text-subtitle-1">{{ recipes[recipeIndex].description }}</span>
<p class="text-justify mt-4">
{{ recipes[recipeIndex].steps }}
</p>
</v-col>
<v-col cols="12" sm="6" class="d-flex align-center justify-center">
<div class="thumbnail">
<img :src="recipes[recipeIndex].image" alt="Beach Scene" style="width: 100%;" />
</div>
</v-col>
</v-row>
</v-container>
</v-sheet>
</v-expand-transition>
If you need to get the info from a secondary api call. You can set up a watcher on the recipeIndex variable to obtain the recipe info everytime it changes.
I'm building an vue2.js app, which gets data from an API and shows it within an vuetify data-iterator and on a leaflet map.
The App.vue component handles the communication between the other components (FilterPanel, ListPanel and MapPanel) ...
<template>
<div id="app">
<v-app id="inspire">
<v-app>
<v-navigation-drawer app width="26em" class="pb-16 pb-lg-0">
<FilterPanel #change="getData" />
</v-navigation-drawer>
<v-sheet id="widget-panel" app class="open" :elevation="8">
<v-container
class="grey lighten-5 scrollContainer"
style="display: flex; overflow-y: auto; flex: 1"
>
<ListPanel :loading="loading" :data="data">
<template #card="{ data }">
<DataCard :data="data" :id="'data' + data.id"></DataCard>
</template>
</ListPanel>
</v-container>
</v-sheet>
<v-main>
<MapPanel :loading="loading" :data="data" />
</v-main>
</v-app>
</v-app>
</div>
</template>
.. and the the API call to get the data.
...
methods: {
getData() {
this.loading = true;
fetch("https://jsonplaceholder.typicode.com/posts")
.then((response) => response.json())
.then((json) => (this.data = json))
.finally(() => (this.loading = false));
},
},
...
Within the ListPanel.vue component an slot is defined, so it can be used somewhere else with other data visualization.
<template>
<v-data-iterator
no-results-text="no - data"
loading="loading"
loading-text="loading - data"
no-data-text="no - data"
:items="data"
hide-default-footer
disable-pagination
>
<template v-slot:default="props">
<v-row>
<v-col v-for="item in props.items" :key="item.id" cols="12">
<slot name="card" :data="item">
no slot provided
</slot>
</v-col>
</v-row>
</template>
</v-data-iterator>
</template>
<script>
export default {
name: "ListPanel",
props: ["data", "loading"],
};
</script>
The MapPanel.vue component shows all data entries on the map with clickable markers, which will open popups to show some information about the data. The map also holds an loading indicator (v-progress-linear) to show if data is loading or not.
<template>
<l-map
id="map"
ref="myMap"
:style="styleObject"
v-if="showMap"
:zoom="zoom"
:center="center"
:options="mapOptions"
>
<v-progress-linear
style="z-index: 800 !important"
:indeterminate="loading"
:active="loading"
absolute
top
color="info"
></v-progress-linear>
<l-tile-layer :url="url" :attribution="attribution" />
<l-control-zoom position="bottomright"></l-control-zoom>
<l-marker
v-for="(item, index) in markers"
:key="'marker-' + index"
:lat-lng="item.location"
>
<l-popup :options="getPopupOptions(item.id)">
<DataCard :data="item" showRequest flat></DataCard>
</l-popup>
</l-marker>
</l-map>
</template>
For better visual representation I'm using an reusable component (DataCard) with v-card to show the necessary data.
I have setup a simplified version of the app. https://codesandbox.io/s/sleepy-hoover-s5w5l
Loading the app or getting the data, let the app freezes for some seconds. You'll see it at the progress bar on the top. The animation stops!
I figured out, that the v-card component is slowing down the whole app. If I remove the card component entirely, loading the data seems to work just fine.
Getting the data from the API isn't the problem, since getting the data from it is very fast.
Vue DevTools Extension within FireFox shows Problems with the Map Markes and the DataCard component.
So I'm asking, what I'm doing wrong with the DataCard Component ?
I have a Vue application running Vuetify but neither of these seem to be equipped to handle my desire to limit the maximum length of the page to be such that there is no scrolling. I hope that makes sense. My hope is to just pull up a screen with a bunch of routing to similarly formatted screens. Of course, the user could make the window smaller, in which case I would need scrolling. So how would I set that up when I want to have the page open to full screen with a maximum page length that will prevent the NEED for scrolling, but still allow scrolling if the need is there due to the user resizing the page to something a good bit smaller?
I spent hours looking around for details on this but didn't find anything that really seemed to be a direct solution. How can I set a max page length? Would CSS offer this? I saw a solution putting CSS in the <head>-tag but with a Vue application this head tag doesn't get used in the same way as typical HTML pages.
EDIT: because I don't think it's clear that because I'm working in vue/vuetify the solution might be different from the general case, I think it is best if I provide my App.vue and an example page.

By default, if the HTML content is larger than the window, the browser will create scrollbars and if it's smaller than the window there won't be a scroll. However, I don't think this is what you're really asking for. I think you're trying to change the window size itself.
I'm going to start by saying its very bad practice to modify the size of the user's browser window. You should work to make your content fit instead.
That said, as Vue.js and Vuetify are built on Javascript, and you'll need to write some custom JS to resize the browser window. The default overflow on the <body> tag (yes those exist in a Vue app) will take care of the scrolling...
window.resizeTo(width, height);
Should be called after Vue has rendered the content to the screen so inside Vue's Mounted Lifecycle hook.
Now, I assume the height of the content changes so you would want to grab the height of the Vue app div.
var newHeight = document.getElementById('app').innerHeight()
You also want to get the screen size so you don't make the window larger than the screen. You can get that height from the screen object.
var screenHeight = window.screen.height
so
if(newHeight < screenHeight){
window.resizeTo('800px', newHeight);
} else {
window.resizeTo('800px', screenHeight);
}
Before you do this
You should know that most modern browsers BLOCK the window.resizeTo() function so again you should find a different solution to the problem.
You Can nest your content inside another div element.If max-height of your inner div is equal to the height of its container, scroll bar will never appear. if you want to see scroll bar use this.
.scrollDiv {
height:auto;
max-height:150%;
overflow:auto;
}
Hii I am working on the Vue.js template and I stuck at a point where I need to show dynamic v-dialog using looping statement but now it shows all.
Dom:
<template v-for="item of faq">
<div :key="item.category">
<h4>{{ item.heading }}</h4>
<div v-for="subitems of item.content" :key="subitems.qus">
<v-dialog
v-model="dialog"
width="500"
>
<template v-slot:activator="{on}">
{{subitems.qus}}
</template>
<v-card>
<v-card-title
class="headline grey lighten-2"
primary-title
>
Privacy Policy
</v-card-title>
<v-card-text>
{{ subitems.ans }}
</v-card-text>
<v-divider></v-divider>
</v-card>
</v-dialog>
</div>
</div>
</template>
Script:
export default {
data: () => ({
faq,
dialog:false,
}),
}
I do not understand how I can do this. If I click on one button then it shows all.
There must a design a pattern for this one but a quick solution would be to create array of booleans for v-models of dialogs. something like below
export default {
data: () => ({
faq,
dialog: [] // Array instead of Boolean.
}),
}
and
<template v-for="item of faq">
<div :key="item.category">
<h4>{{ item.heading }}</h4>
<div v-for="(subitems, index) of item.content" :key="subitems.qus">
<v-dialog
v-model="dialog[index]"
width="500"
>
<template v-slot:activator="{on}">
{{subitems.qus}}
</template>
<v-card>
<v-card-title
class="headline grey lighten-2"
primary-title
>
Privacy Policy
</v-card-title>
<v-card-text>
{{ subitems.ans }}
</v-card-text>
<v-divider></v-divider>
</v-card>
</v-dialog>
</div>
</div>
</template>
Brother, you are doing a very small mistake, you should not keep your v-dialog component inside your loop, take this out from loop block and don't take dialog as empty array keep it false.
I created a simple Contact list with an input to add the contact items but after I add a few items it's not resizing.
I used this as an example and there is resizing but not in my code:
https://v2.vuejs.org/v2/guide/list.html
Could anyone help me with that?

</v-list-tile-title>\
',
props: ['title']
})
new Vue({

newContact: '',
contacts: [],

Thank you!
Use v-for on v-list-tile component (see vuetify examples).
<v-list-tile
v-for="(contact, index) in contacts"
:key="contact.id"
>
That will produce multiple lis that you want from your examples (currently you only have one li element in list because of v-for on title, so that's why it's not working properly)
