I work with Vue 3 and Bootstrap 5. I have a props called number (get me integers from 1 - 10).
Now I want to work with with my number in my scrollbar-class.
I've tried as following but it's not working. I get no error - it's simply not working.
How can I fix that? Thank You!
<template>
<div class="scrollbar"
</div>
</template>
<script>
export default {
props: {
number: Number,
}
}
</script>
<style>
.scrollbar {
height: calc(500px + (var(--number) * 20 px));
}
</style>
You can use v-bind in your <style> tag to bind a data property to your CSS.
It will also reactivly update, if your state changes.
<template>
<div class="scrollbar">
</div>
</template>
<script>
export default {
props: {
number: Number,
}
}
</script>
<style>
.scrollbar {
height: calc(500px + (v-bind(number) * 20px));
}
</style>

I am creating a formulary and some fields are intended to occupy just 50% of the size that a normal field would take.
It is a dynamic formulary so i use a v-for that take a form object from vuex and use its data to summon the correct component on screen.
I em using because i have TextField's, DateField's, CheckField's and all this configuration is made in the forms object.
Now, to the code:
At store/module/forms.js (vuex) (it is a list of objects like this one):
[
{
name: 'familiarIncome',
type: 'TextField',
value: '',
options: {
dataname: 'familiarIncome',
mandatory: true,
label: 'Renda familiar',
placeholder: '',
rules: fieldRules.float('a renda familiar'),
css: 'width: 50%', // Attention here. This will be injected into component
},
}
]
Then, at pages/formulario.js: (note that until now i wrote only 3 input components)
<template>
<v-app class="container d-flex justify-center">
<h1>Coleta de dados</h1>
<v-form class="container fluid">
<h2>Dados pessoais</h2>
<div class="personal-data d-flex flex-wrap">
<div
v-for="field in getForm.personalData"
:key="field.name"
class="field"
<!-- Pay attention to this class up here (field) -->
>
<component
:is="field.type"
<!-- Here is where all those options -including "width: 50%" are being injected -->
v-bind="field.options"
#change="updateData((section = 'personalData'), $event)"
></component>
</div>
</div>
<div class="social-benefits"></div>
<div class="is-disabled"></div>
<div class="address"></div>
<div class="child-already-born"></div>
</v-form>
</v-app>
</template>
<script>
import { mapGetters } from 'vuex'
import TextField from '../components/inputs/textfield.vue'
import ConfirmButton from '../components/inputs/confirmbutton.vue'
import SelectField from '../components/inputs/selectfield.vue'
export default {
name: 'Formulario',
components: { TextField, ConfirmButton, SelectField },
data() {
return {
formToken: this.$route.params.token,
}
},
computed: {
...mapGetters(['getForm']),
},
methods: {
updateData(section, eventData) {
const data = {
section,
...eventData,
}
this.$store.commit('setFormField', data)
console.log(this.$store.state)
},
},
}
</script>
<style scoped>
.field {
padding: 7px;
width: 50%;
}
h1 {
font-size: 36px;
}
h2 {
font-size: 24px;
}
</style>
And now a print of the web page:
If i missed any important info, please let me know ;)
(just for the case where someone complains, i searched A LOT before asking here ;) )
Ok so i figured it out some minutes later by trying to do things that would look wrong (great technique by the way)
What i did was taking out the wrapping div arount the <component> tag, so then the 50% width would really take the right effect.
I can't change style in ant-tooltip on nuxtjs. I access to class ant-tooltip-inner but it don't changing.
<div class="box-form-input">
<a-tooltip placement="topRight" trigger="focus">
<template slot="title">
<span>Please fill in your Fullname</span>
</template>
<a-input
v-model="full_name"
/>
</a-tooltip>
</div>
<style>
.ant-tooltip-inner {
background-color: red;
}
</style>
Overriding Antd tooltip in vue.js works as expected.
<template>
<div id="app">
<!-- remove h3 tag causes wrong arrow direction -->
<h3>try to remove this element.
<br>After removed, the tooltip arrow changed direction.
</h3>
<a-tooltip placement="left" title="wrong arrow direction">
<span>why don't use popper.js</span>
</a-tooltip>
</div>
</template>
<script>
import HelloWorld from "./components/HelloWorld";
export default {
name: "App",
components: {
HelloWorld
}
};
</script>
<style>
.ant-tooltip-inner {
background-color: red;
}
</style>

I'm writing a Vue component, which accepts 2 slots:
<template>
<div class="Component">
<div class="Component-Label">
<slot
name="label"
class="Component-LabelInner"
/>
</div>
<div class="Component-Input">
<slot
name="input"
class="Component-InputInner"
/>
</div>
</div>
</template>
<style scoped>
.Component { ... }
.Component-Label { ... }
.Component-LabelInner { ... }
.Component-Input { ... }
.Component-InputInner { width: 100%; ... }
</style>
For layout purposes, I absolutely need to apply some styles to the <slot> elements - the ones with Component-LabelInner and Component-InputInner classes.
(To be precise I need to apply a rule width: 100% to the Component-InputInner, as usually I'll pass there <input> element and I want everything I pass there to stretch to the container.)
The problem is that after <slot> elements get replaced by the content provided to the slots, class attribute isn't inherited (it seems no attributes are inherited on slots) and CSS selectors for .Component-LabelInner and .Component-InputInner don't work.
Can you somehow add CSS classes to the element that <slot> gets replaced with?
You can not bind class to slot tag. There are some solutions to handle this case:
With Vue mounted hook (it works but looks as bad practice):
Vue.component("slots-comp", {
template: "#slotsCompTemplate",
mounted() {
// each slot is an array, because you can pass a set of nodes wrap them with template tag
// I use only first VNode for example
this.$slots.one && this.$slots.one[0].elm.classList.add("one");
this.$slots.two && this.$slots.two[0].elm.classList.add("two");
}
});
new Vue({
el: "#app",
data: {}
})
.one {
color: red
}
.two {
color: blue
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.16/vue.min.js"></script>
<div id="app">
<slots-comp>
<div slot="one">One</div>
<div slot="two">Two</div>
</slots-comp>
</div>
<script type="text/x-template" id="slotsCompTemplate">
<div>
<slot name="one"></slot>
<slot name="two"></slot>
</div>
</script>
Pass neccessary classes as props to scoped slot(it is not fully encapsulated solution):
Vue.component("slots-comp", {
template: "#slotsCompTemplate",
data() {
return {
classes: {
one: ["one"],
two: ["two"]
}
}
}
});
new Vue({
el: "#app",
data: {}
})
.one {
color: red
}
.two {
color: blue
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.16/vue.min.js"></script>
<div id="app">
<slots-comp>
<div slot-scope="props" :class="props.classes.one" slot="one">One</div>
<div slot-scope="props" :class="props.classes.two" slot="two">Two</div>
</slots-comp>
</div>
<script type="text/x-template" id="slotsCompTemplate">
<div>
<slot :classes="classes" name="one"></slot>
<slot :classes="classes" name="two"></slot>
</div>
</script>
Add changes to CSS to apply styles on all internal elements:
.Component-Input > *
{
/* my rules for child elements */
}
.Component-Label> *
{
/* my rules for child elements */
}
Or add wrapper element for slots with classes Component-InputInner etc. and add similar styles for them.
Hope it will help.
Im currently trying to learn vue.js and am trying to add styles to a component. The component itself works, and the functionality (alert message) works aswell but I cant get the styles to implement.
(Now I understand that technically I'm not using vue.js to style in my first example but this is to show what I had tried)
Attempt 1:
<template>
<div class="container">
<input id="test-btn" type="button" v-on:click= clicked()>
</div>
</template>
<script>
export default{
name: 'test-btn',
methods: {
clicked: function () {
alert("Here's your message")
}
}
}
</script>
<style scoped>
#test-btn{
color: #CC00CC;
width: 150;
height: 50;
}
</style>
Though I had changed the color width and height the button remains the generic grey and doesn't change width or height (it just stays a square). but it does work when I click it (at least something works).
Since I couldn't get that to work I tried to use the v-bind method.
Attempt 2:
<template>
<div class="container">
<input id="test-btn" type="button" v-on:click= clicked() v-bind:style="btnStyle">
</div>
</template>
<script>
export default{
name: 'test-btn',
methods: {
clicked: function () {
alert("Here's your message")
}
},
data: {
btnStyle: {
color: 'red',
width: 100,
height: 50
}
}
}
</script>
<style scoped>
/* #test-btn{
color: #CC00CC;
width: 150;
height: 50;
}*/
</style>
This attempt at v-bind also had failed as well. A friend told me that buttons are difficult to make the styling work and it may not be an error with my code, it may be default styling that is over riding it (I cant accept that). So what I did was tried to add !important to my css color line in the script tags but that didn't work either.
Your <button> is not styled because you have a CSS issue. Add px to width and height. See CSS in the demo below.
The color CSS property is the font color. To change the <button> color use background: yellow;.
new Vue({
el: '#app',
methods: {
clicked: function() {
alert("Here's your message")
}
}
})
#test-btn {
color: #CC00CC;
background-color: yellow;
width: 150px; /* was 150, now 150px */
height: 50px;
}
<script src="https://unpkg.com/vue"></script>
<div id="app">
<div class="container">
<input id="test-btn" type="button" v-on:click="clicked()" value="Click Me">
</div>
</div>
Works with data and v-bind:style as well (just do width: '150px'; and height: '50px';). To change the background color add background: 'yellow' as well.
new Vue({
el: '#app',
data: {
btnStyle: {
color: '#CC00CC',
background: 'yellow',
width: '100px',
height: '50px'
}
},
methods: {
clicked: function() {
alert("Here's your message")
}
}
})
<script src="https://unpkg.com/vue"></script>
<div id="app">
<div class="container">
<input id="test-btn" type="button" v-on:click="clicked()" v-bind:style="btnStyle" value="CLICK ME">
</div>
</div>
Disclaimer: I have tried to read the docs before opening this question.
I have this component:
<template>
<accordion id="facilities-menu" :one-at-atime="true">
<template v-for="facilities in facilitiesGroups">
<panel class="accordion-toggle" :header="`Facilities #${$index+1}`" :is-open="$index === 0">
<ul>
<li v-for="facility in facilities">
{{facility}}
</li>
</ul>
</panel>
</template>
</accordion>
</template>
<style lang="scss" scoped>
#import "../../../styles/theme-colors.scss";
.panel {
background: #5E6466;
border: none;
}
</style>
<script>
import { accordion, panel } from 'vue-strap'
module.exports = {
components: {
accordion, panel
},
data () {
return {
'facilitiesGroups': [['Continente Alfragide', 'Jumbo Almada', 'Portugália'], ['Pingo Doce', 'Lidl', 'Allegro'], ['Casa']]
}
}
}
</script>
And then I instantiate this component like this:
<template>
<div class="user">
<user></user>
</div>
<facilities></facilities>
</template>
<style lang="scss" scoped>
#import "../../../styles/theme-colors";
.user {
width: 100%;
height: auto;
margin-top: 8%;
margin-bottom: 5%;
}
</style>
<script>
import User from './userProfile'
import Facilities from './groupedFacilities'
module.exports = {
components: {
'user': User,
'facilities': Facilities
}
}
</script>
However, you can see that in the first component I am defining the data to be { 'facilitiesGroups': [['Continente Alfragide', 'Jumbo Almada', 'Portugália'], ['Pingo Doce', 'Lidl', 'Allegro'], ['Casa']] }. But i want this to be passed as an argument, not to be statically defined in the component as it is now.
I have read the docs about how could this be done here. But their example...
Vue.component('child', {
// declare the props
props: ['msg'],
// the prop can be used inside templates, and will also
// be set as `this.msg`
template: '<span>{{ msg }}</span>'
})
...Resembles nothing to what I have in my code... I don't even use Vue.component() anywhere!
How come I am using a different "style" of coding with Vue JS (I started from their boilerplate)?
How can I map Vue JS official documentation to this "style"?
How can pass that array as an argument/property?
Thanks!
Your component needs to declare the data you want passed in as 'props'
<script>
import { accordion, panel } from 'vue-strap'
module.exports = {
components: {
accordion, panel
},
props: ['facilitiesGroups']
}
</script>
... then in your parent component template you pass your data as an attribute. Below is an example where "facilitiesGroups" is a data element of your parent component:
<template>
<div class="user">
<user></user>
</div>
<facilities :facilities-groups="facilitiesGroups"></facilities>
</template>
