I am new to Vue. I am building a simple app that will list all countries and when you click on a particular country it shows you more details about the country. Idea is to open country details in a modal.
I'm stuck with displaying that modal. The modal opens, but in the background. It also opens a detail page.
CountryDetail.vue:
<script>
import axios from 'axios';
export default {
name: 'country-detail',
props: [ 'isDarkTheme' ],
data () {
return {
pending: false,
error: null,
countryInfo: null,
alpha3Code: [],
alpha3CodetoString: [],
}
},
mounted () {
this.pending = true;
axios
.get(`https://restcountries.eu/rest/v2/name/${this.$route.params.country}?fullText=true`)
.then((response) => {
(this.countryInfo = response.data)
this.alpha3CodetoString = this.alpha3Code.join(';');
})
.catch(error => (this.error = error ))
.finally( () => { this.pending = false });
},
filters: {
formatNumbers (value) {
return `${value.toLocaleString()}`
}
}
}
</script>
<template>
<modal v-model="show">
<div class="modal-mask" :class="{ darkTheme : isDarkTheme }" name="modal">
<div class="modal-wrapper">
<div class="modal-container">
<div class="modal-header">
<slot name="header">
<h1 v-if="error !== null">Sorry, an error has occurred {{error}}</h1>
<div class="loaderFlex"><div v-if="pending" class="loader"></div></div>
</slot>
</div>
<div v-for="country in countryInfo" class="countryTile modal-body" v-bind:key="country.id">
<slot name="body">
<img v-bind:src="country.flag" alt="Country Flag" class="flag">
<div class="country-details">
<h1>{{country.name}}</h1>
<div class="listDiv">
<ul>
<li><span>Population:</span> {{country.population | formatNumbers }}</li>
<li><span>Capital:</span> {{country.capital}}</li>
<li><span>Iso:</span> {{country.alpha3Code}}</li>
</ul>
<ul>
<li><span>Currencies:</span> {{country.currencies['0'].name}}</li>
<li><span>Languages:</span>
<span
v-for="(language, index) in country.languages"
v-bind:key="index"
class="languages">
{{language.name}}<span v-if="index + 1 < country.languages.length">, </span>
</span>
</li>
</ul>

countryInfo: null,
search: '',
darkMode: false,
}
},
mounted () {
this.pending = true;
axios
.get('https://restcountries.eu/rest/v2/all')
.then(response => (this.countryInfo = response.data))
.catch(error => (this.error = error ))
.finally( () => { this.pending = false });
},
filters: {
formatNumbers (value) {
return `${value.toLocaleString()}`
}
},
computed: {
filteredCountries: function () {
return this.countryInfo.filter((country) => {
if (this.region === '' ) {
return country.name.toLowerCase().match(this.search.toLowerCase());
} else if (this.search !== '') {
return country.name.toLowerCase().match(this.search.toLowerCase());
} else {
return ('blbla');
}
})
}
},
}
</script>
<template>

</router-link>

</template>
The router-link will always redirect you to another page, because its basically <a href="..."> see here. You don't need router if you just want to show the detail on a modal, you could just add the modal component inside the Home.vue component, then bind the modal and the countryName with props, then pass them in when clicking a button.
Home.vue:
<template>
<div>
<button #click="showDetail">
Show Detail
</button>
<CountryDetail :countryName="countryName" :showModal="showModal"/>
<div>
</template>
<script>
import CountryDetail from './CountryDetail.vue'
export default {
name: 'Home',
components: { CountryDetail },
data: () => ({
countryName: '',
showModal: false,
}),
methods: {
showDetail() {
this.showModal = true;
},
},
}
</script>
And instead of making request on mounted, you could use watch to do something like watching for the showModal prop, and make request everytime it has a truthy value. Like this:
CountryDetail.vue:
<template>
<modal v-model="showModal">
<!-- modal content -->
</modal>
</template>
<script>
export default {
name: 'CountryDetail',
props: ['countryName', 'showModal'],
watch: {
'showModal': {
deep: true,
handler(val) {
if (val && this.countryName !== '') {
// Make request
}
}
}
}
}
</script>

When I click the button form other component that emit change of #edit-task-of and #edit-task the it doesn't send the new value of bool and showval to child component the bool value still false as same as first mount and showVal = "" when click button that run test function to see this two value at child. I'm totally new to vue. Thanks
You do mistake in GoTask component , method test, first console.log(this.bools);, bools is local state which is not updated after prop bool changed, just do correct console.log(this.bool);. You don't need to set props to local state, you can use props directly.
GoTask correct example:
props: ["tasker", "showVal", "bool"],
data() {
return {
newTask: {
title: "",
description: "",
},
};
},
methods: {
test() {
console.log(this.bool);
console.log(this.showVal);
},

I'm working on this app and the idea is to show details of the cars in a sidebar on click. There are several issues like the sidebar is showing four times and I resolve it somehow but I don't know why is it showing four times. now I don't getting any response on emit call help me out please, I try $parent.$emit, $root.$emit but not seems working!!!

Thanks for your help.
So a few things you can try to fix this
in your Home.vue you can change
#emitData="testingEmit()"
to
#emitData="testingEmit"
// or
#emitData="testingEmit($event)"
You are telling to the function testingEmit that is not params to parse. So you need to take out the () and Vue will parse everything that comes from the $event or you cant say put the $event as a param in your testingEmit (second option).
For your SingleGarage.vue you can take the $parent.$emit and replace it with
this.$emit('emitData',this.detail.cars.vehicles[vehicleIndex].make)
I have 2 modal windows: register and login. When I click to "Sign Up" button, the modal window should change. What should I do?
This is a project link.
https://jsfiddle.net/Alienwave/0kqj7tr1/4/
Vue.component('signup', {
template: '#signup-template'
})
Vue.component('login', {
template: '#login-template',
data() {
return {
loginInput: '',
passwordInput: ''
}
},
methods: {
sendRequest(e) {
//code not here
},
changeModal() {
// THIS!!
}
}
});
new Vue({
el: "#app",
data() {
return {
showLogin: true,
showSignup: false
}
}
});
This is login template:
<template id="login-template">
<transition name="modal">
<div class="login-mask">
<div class="login-wrapper">
<div class="login-container">
<div class="login-footer">
<slot name="footer">
<div class="change-mode">
<button class="change-mode-reg" #click="">Sign up</button> <!-- THIS BUTTON SHOULD CHANGE MODAL! -->
</div>
</slot>
</div>
</div>
</div>
</div>
</transition>
</template>
Register template looks the same.
I cut a big chunk.
This is a good use case for Vue's custom events. I would update your code as follows:
#login-template
...
<div class="login-footer">
<slot name="footer">
<div class="change-mode">
<button class="change-mode-reg" #click="changeModal">Sign up</button>
<div class="change-mode-line"></div>
</div>
</slot>
</div>
...
login component
Vue.component('login', {
template: '#login-template',
data() {
return {
loginInput: '',
passwordInput: ''
}
},
methods: {
sendRequest(e) {
//code not here
},
changeModal() {
this.$emit('change');
}
}
});
#app
<div id="app">
<login v-if="showLogin" #close="showLogin = false" #change="changeModal"></login>
<signup v-if="showSignup" #close="showSignup = false"></signup>
</div>
Here is an updated fiddle.
(NOTE: it looks like you might have some other issues going on here, but this gets your modal switching issue fixed.)
My question is about core logic for the thing below
1) I have a Section Component and a Modal Component
2) In the Section Component i have an array of objects with title and description
3) In the Modal Component i have a template for the modal (im using Bulma framework for the modal)
Now, in the Section i have 7 buttons with a v-for loop to assign 'is-active' class and on each button click an individual modal opens.
Question: How do i parse data into the modal ? I want my modal to be reusable. So at the start my modal is empty at all. On button1 click i have title1 descr1, on button2 title2 descr2 and etc
My code:
Section Component:
<template>
<base-section name="clusters">
<div class="section-map">
<button
class="section-btn"
v-for="(item, index) in sectionItems"
:key="index"
:class="[`section-btn-num${index + 1}`, {'is-active': item.state}]"
#click="toggleModal(item)"
>
<div class="section-btn__text">
{{ item.title }}
</div>
</button>
</div>
<div class="modal"
v-for="(item, index) in sectionItems"
:key="index"
:class="{'is-active': item.state}"
>
<div class="modal-background"></div>
<div class="modal-content">
</div>
<button
#click="item.state = false"
class="modal-close is-large"
aria-label="close">
</button>
</div>
</base-section>
</template>
<script>
import BaseSection from './Section';
import BaseModal from './Modal';
export default {
components: {
BaseSection,
BaseModal,
},
methods: {
toggleModal: (item) => {
item.state = !item.state;
}
},
data() {
return {
sectionItems: [
{
title: 'title1',
},
{
title: 'title2',
description: 'descr',
},
{
title: 'title3',
description: 'descr',
},
{
title: 'title4',
description: 'descr',
},
{
title: 'title5',
description: 'descr',
},
{
title: 'title6',
description: 'descr',
},
{
title: 'title7',
description: 'descr',
},
].map(item => ({ ...item, state: false }))
};
}
};
</script>
<styles>
/* are skipped */
</styles>
Modal Component:
<template>
<div class="modal">
<div class="modal-background"></div>
<div class="modal-content">
<div class="modal__header">
<slot name="modal__header">
</slot>
</div>
<div class="modal__body">
<slot name="modal__body">
</slot>
</div>
</div>
<button
#click="item.state = false"
class="modal-close is-large"
aria-label="close">
</button>
</div>
</template>
<script>
import ClustersSection from './ClustersSection';
export default {
components: {
ClustersSection,
},
props: {
}
},
};
</script>
<style lang="scss">
</style>
Since you already defined slots in your component you can pass data to it via slots. E.g.
<your-modal-component>
<template slot="modal__header">
header bla bla a
</template>
<template slot="modal__body">
body anything here like <p> hehe</p>
</template>
</your-modal-component>
How would I show line space in vue.js. Right now everything is after each other....
Already tried this:
https://laracasts.com/discuss/channels/vue/vuejs-how-to-return-a-string-with-line-break-from-database
But nothing seems work. Trying this for 3 days now -_-.
I'm using Vue.js 1.0 and browserify.
Thanks a lot!

},
route: {

this.loading = true;
this.page = to.query.page || 1;
Topic.show(this.$route.params.topic, this.page)
.then((data) => {
this.topic = data.data.topic;
if(!data.data.messages.data.length == 0) {
this.messages = data.data.messages.data;
this.lastPage = data.data.messages.last_page;
} else {
this.noMessages = true;
}
this.loading = false;
});
}
}
}
</script>
When I do it like this:
<div class="Message__body__message">
<p>{{ message.message.split("\n"); }}</p>
</div>
It only adds comma's.
--EDIT--
Set container white-space style to pre-line, as in:
<div style="white-space: pre-line;">{{textWithLineBreaks}}</div>
When you split the message, you get multiple data items, which you should handle with a v-for.
But also see LMK's answer wherein you don't have to split the message.
new Vue({
el: '#app',
data: {
message: `this is a message
it is broken across
several lines
it looks like a poem`
}
});
<script src="//cdnjs.cloudflare.com/ajax/libs/vue/2.0.3/vue.min.js"></script>
<div id="app">
<template v-for="line in message.split('\n')">{{line}}<br></template>
</div>
You have to transform your data before rendering it with Vue.
const lines = stringWithLineBreaks.split('\n')
// then render the lines
I can give a more specific answer if you share the code you're working with.
