Responsive and dynamic background images in Vue.js - css

I'm trying to build a vue.js front-end and the design is calling for 100% width tiles with a dynamic background image that will be passed along the rest of the content to the page. I already have the payload passing to the component that renders each tile, but I need to render the background image for each of the tiles. I also need to mention that the images are actually 3 images for each tile that need to render for each of our 3 breakpoints. So far I was able to pass one image by using :style="'background-image: url(' + backgroundImage + ')'" but this only serves one image per tile. My question is, what would be the best way to pass all 3 images per tile and render them correctly?
I have heard online that I should just use srcset and pass all 3 to an <img> tag, and make that image the background by using CSS, but that just seems unorthodox.
Is there a more elegant way to deal with responsive background images in reusable components in vue.js?

Vue3 and Element plus dynamic column not show data

I try to loop through Element-plus table column as <el-table-column v-for="(d ,i) in data.values" :key="i" :prop="d.value" :label="d.label" /> but no result showed in browser I trying google for hours and trying several examples and solutions but nothing works for me on this issue.
full example here
<template>
<el-table :data="data" class="full-table">
<el-table-column fixed prop="name" label="Employee" width="250"/>
<el-table-column prop="phone" label="Phone"/>
<el-table-column v-for="(d ,i) in data.values" :key="i" :prop="d.value" :label="d.label" />
</el-table>
</template>
<script setup lang="ts">
import {ElTable, ElTableColumn} from 'element-plus'
const data = [
{
name: 'personal1',
phone: 6767000,
values: [
{
label: 'email',
value: 'personal1#mail.com',
}
]
},
{
name: 'personal2',
phone: 9090000,
values: [
{
label: 'email',
value: 'personal2#mail.com',
}
]
},
]
</script>
The result is show like this no extra column for v-for
What do i do wrong?. please advice
You don't need value in the template as explained here.
Try with v-for="(d ,i) in data" and :prop="d".
Also, feel free to double check what you have in your Vue devtools to be sure.
I don't have an Element UI example but this is how the Vue part works when using the Composition API.
<template>
<div v-for="(d ,i) in data" :key="d.name" :prop="d" :label="d.label">
{{ d.name }}
</div>
</template>
<script setup lang="ts">
import { reactive } from 'vue'
const data = reactive([
{
name: 'personal1',
phone: 6767000,
values: [
{
label: 'email',
value: 'personal1#mail.com',
}
]
},
{
name: 'personal2',
phone: 9090000,
values: [
{
label: 'email',
value: 'personal2#mail.com',
}
]
},
])
</script>
Overall, I recommend that you give a read to that part of the doc to have a fully usable Vue example with some working reactivity.
Element UI's prop will follow up accordingly.

VUE3.JS - Modal in a loop

I have a GET request in my home.vue component.
This query allows me to get an array of objects.
To display all the objects, I do a v-for loop and everything works fine.
<div class="commentaires" v-for="(com, index) of coms" :key="index">
My concern is that I want to display an image by clicking on it (coms[index].imageUrl), in a modal (popup).
The modal is displayed fine but not with the correct image, i.e. the modal displays the last image obtained in the loop, which is not correct.
Here is the full code of my home.vue component
<template>
<div class="container">
<div class="commentaires" v-for="(com, index) of coms" :key="index">
<modale :imageUrl="com.imageUrl_$this.index" :revele="revele" :toggleModale="toggleModale"></modale>
<img class="photo" :src=""" alt="image du commentaire" #click="toggleModale">
</div>
</div>
</template>
<script>
//import axios from "axios";
import axios from "axios";
import Modale from "./Modale";
export default {
name: 'HoMe',
data() {
return {
coms: [],
revele: false
}
},
components: {
modale: Modale
},
methods: {
toggleModale: function () {
this.revele = !this.revele;
},
</script>
Here is my modale.vue component
<template>
<div class="bloc-modale" v-if="revele">
<div class="overlay" #click="toggleModale"></div>
<div class="modale card">
<div v-on:click="toggleModale" class="btn-modale btn btn-danger">X</div>
<img :src=""" alt="image du commentaire" id="modal">
</div>
</div>
</template>
<script>
export default {
name: "Modale",
props: ["revele", "toggleModale", "imageUrl"],
};
</script>
I've been working on it for 1 week but I can't, so thank you very much for your help...
in your v-for loop you're binding the same revele and toggleModale to every modal. When there is only one revele then any time it's true, all modals will be displayed. It's therefore likely you're actually opening all modals and simply seeing the last one in the stack. You should modify coms so that each item has it's own revele, e.g.:
coms = [
{
imageUrl: 'asdf',
revele: false
},
{
imageUrl: 'zxcv',
revele: false
},
{
imageUrl: 'ghjk',
revele: false
}
];
then inside your v-for:
<modale
:image-url="com.imageUrl"
:revele="com.revele"
#toggle-modale="com.revele = false"
></modale>
<img class="photo" :src=""" alt="image du commentaire" #click="com.revele = true">
passing the same function as a prop to each modal to control the value of revele is also a bad idea. Anytime a prop value needs to be modified in a child component, the child should emit an event telling the parent to modify the value. Notice in my code snippet above I replaced the prop with an event handler that turns the revele value specific to that modal to false. Inside each modal you should fire that event:
modale.vue
<div class="btn-modale btn btn-danger" #click="$emit('toggle-modale')">
X
</div>
This way you don't need any function at all to control the display of the modals.

How to display preview of the selected image using Angular

I would like to show the preview of the selected image busing Angular, as of now if we click all images are selected, can any one suggest me how to show preview of the selected one and if we select another image previously selected image should be unselect and display new image.
public images: Array<object> = [
{
src: 'https://picsum.photos/250/250/?image=110',
description: 'Notte in hotel di lusso',
price: 250
},
{
src: 'https://picsum.photos/250/250/?image=58',
description: 'Escursione alla scoperta degli animali dell\'isola',
price: 160
}
];
HTML:
<div class="image__container" [ngClass]="{ 'selected': selected }">
<img class="image" [src]="item.src">
<div
class="image__description"
(click)="selected = !selected"
>
<div class="image__description--content">
<div class="image__description--price">
{{ item.price }}
</div>
</div>
</div>
Stackblitz
Thanks for the detailed question, You can check the below stackblitz, I needed to just add a parent property that tracks the currently selected row, then emit an event from the child which updates the latest value from the child. Then if the changes do not show up, we can call this.cdr.detectChanges() to trigger change detection manually. Please check the below code and let me know if any questions.
import {
Component,
ChangeDetectionStrategy,
ChangeDetectorRef,
ViewChildren,
QueryList,

changeDetection: ChangeDetectionStrategy.OnPush,
})
export class GridComponent {
currentlySelected;
#ViewChildren('gridItem') gridItems: QueryList<GridItemComponent>;

Apostrophe CMS align custom layout widget

I'm sure there's a really simple solution to this but I can't seem to find it, and I haven't found the question asked here already.
I'm trying to align a layout widget (area) so that when another widget is added it appears to the right of the first widget and not below.
I was hoping i could sort this with flexbox and the artistContainer class but it doesn't seem to be possible.
Dev tools and desired outcome
home.html
<section class="bodysect--dark" id="artists">
<h2 class="body__heading">Artists</h2>
<div class="artistContainer">
{{
apos.area(data.page, 'artist', {
widgets: {
artist: {}
}
})
}}
</div>
</section>
Widget.html
<div class="artist">
<div class="artistImage">
{{ apos.singleton(data.widget, 'areaImage', 'apostrophe-images', {
widgets: {
'apostrophe-images': {}
}
}) }}
</div>
<div class="artistName">
{{ apos.singleton(data.widget, 'singletonName', 'apostrophe-rich-text', {
widgets: {
'apostrophe-rich-text': {}
}
}) }}
</div>
<div class="artistBio">
{{ apos.singleton(data.widget, 'singletonBio', 'apostrophe-rich-text', {
widgets: {
'apostrophe-rich-text': {}
}
}) }}
</div>
</div>
widget index.js
module.exports = {
extend: 'apostrophe-widgets',
label: 'Artist',
contextualOnly: true,
addFields: [
{
name: 'artistImage',
type: 'singleton',
label: 'Image Area',
required: true
},
{
name: 'artistName',
type: 'singleton',
label: 'Name Area',
required: true
},
{
name: 'artistBio',
type: 'singleton',
label: 'Bio Area',
required: true
},
]
};
Thanks in advance!
There is nothing preventing you from lining up horizontally, however, to maintain the proper flex contexts, you'll need to apply styles to apostrophe-generated markup instead of just your project level classes. Here is some sample code I just demo'd
.horizontal-area {
.apos-area-widgets, // proper context for logged-in user
.apos-area { // proper context for logged-out user
display: flex;
}
.apos-area-widget-wrapper {
flex-grow: 1;
flex-basis: 0;
}
}

You might want to provide additional UI changes to adjust the horizontal Add Content line within the horizontal area scope.
