First time with vue. I am learning it playing around with some examples from Laracasts. I cannot get external template to render and the console shows cannot find element: #toolbar-chat.
My template is:
<template>
<div id="toolbar-chat">
<div class="toolbar-chat">
<ul v-for="chat in messages">
<li><b>#{{ chat.nickname }} says:</b> #{{ chat.message }}</li>
</ul>
</div>
<div class="input-group input-group-sm">
<input class="form-control" value="" placeholder="Type message..." required="required" maxlength="140" v-model="newMsg">
<div class="input-group-btn">
<button class="btn btn-primary" type="button" #click="press">
<i class="fa fa-paper-plane"></i>
</button>
</div>
</div>
</div>
</template>
<script>
export default {
mounted() {
console.log('Component mounted.')
},
data() {
return {
nickname: [],
message: ''
}
},
ready() {
Echo.channel(chat_channel)
.listen('ChatMessageWasReceived', (data) => {
// Push data to messages list.
this.messages.push({
message: data.chat.message,
nickname: data.player.nickname
});
});
},
methods: {
press() {
// Send message to backend.
this.$http.post(chat_send_route, {message: this.newMsg})
.then((response) => {
// Clear input field.
this.newMsg = '';
});
}
}
};
</script>
My HTML contains the following tag:
<div class="col-xs-12 col-md-4" id="toolbarChat">
<my-chat></my-chat>
</div>
My vue component call is inside a document ready function like this:
require('./../app/bootstrap');
$(document).ready(function()
{
....
// Set up chat
Vue.component('my-chat', require('./../generic/chat.vue'));
const app = new Vue({
el: '#toolbar-chat'
});
});
And I include vue in my bootstrap file like this, then compile with webpack and no errors.
window.Vue = require('vue');
Why is my HTML template not rendering?
In your HTML you have the following div:
<div class="col-xs-12 col-md-4" id="toolbarChat">
<my-chat></my-chat>
</div>
Change it to
<div class="col-xs-12 col-md-4" id="toolbar-chat">
<my-chat></my-chat>
</div>
Because that is the id that new Vue({el: "#toolbar-chat",...}) is looking for.

I'm beginner in VueJS and hoping for your help.
I'm trying to create Weather forecast app based on OpenWeatherMap API.
The concept is such that:
Enter some location to input on homepage and click to search button. (in my code it's a component Search.vue)
Redirecting to another page and show results - current weather and forecast for next 6 days. (component Weather.vue)
I created function with two consistent fetch calls. First fetch taking entered input query and return needed data from Current Weather Data API. After that, function run second fetch to One Call API based on latitude longitude from first fetch.
Everything is working and showing fine, but i don't undestand why i have an error Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '1') in console:
Сan someone know how to fix this error?

const router = createRouter({

export default router
From what I guess (given the code and the error), there might be an issue with the objects you are receiving from the API.
The error message suggests you are trying to read something from an array at a specific index that is undefined.
The only occurrence in your code that could cause this error is from the template, where you are reading, for example:
{{ forecast.daily[day].dt }}
{{ Math.round(forecast.daily[day].temp.day) }}
I can't tell exactly which one is it, but try to double check the shape of the objects you are working with.

Pressing the enter key is submitting your form. The prevent modifier is on the input but should be on the <form>:
<form #submit.prevent>
And it can be removed from your keypress event listener:
v-on:keyup.enter="search"
In the following Vue Component I want to loop through dwarfs array. And as long as I am in the current component, everything is fine (TEST) and also all the following properties are correct.
Currenct_Component.vue :
<template>
<div>
<h2>Stamm: {{ tribeName }}</h2>
<div class="card-container">
<div class="card" style="width: 18rem;" v-for="dwarf in dwarfs" :key="dwarf.name">
<!-- TEST -->
<p>{{dwarf}}</p>
<!-- CHILD COMPONENT -->
<app-modal
:showModal="showModal"
:targetDwarf="dwarf"
#close="showModal = false"
#weaponAdded="notifyApp"
/>
<!-- <img class="card-img-top" src="" alt="Card image cap">-->
<div class="card-body">
<h3 class="card-title" ref="dwarfName">{{ dwarf.name }}</h3>
<hr>
<ul class="dwarf-details">
<li><strong>Alter:</strong> {{ dwarf.age }}</li>
<li><strong>Waffen:</strong>
<ul v-for="weapon in dwarf.weapons">
<li><span>Name: {{ weapon.name }} | Magischer Wert: {{ weapon.magicValue }}</span></li>
</ul>
</li>
<li><strong>Powerfactor:</strong> {{ dwarf.weapons.map(weapon => weapon.magicValue).reduce((accumulator, currentValue) => accumulator + currentValue) }}</li>
</ul>
<button class="card-button" #click="showModal = true"><span class="plus-sign">+</span> Waffe</button>
</div>
</div>
</div>
<button id="backBtn" #click="onClick">Zurück</button>
</div>
</template>
<script>
import Modal from './NewWeaponModal.vue';
export default {
data() {
return {
showModal: false,
}
},
components: { appModal : Modal },
props: ['tribeName', 'dwarfs'],
methods: {
onClick() {
this.$emit('backBtn')
},
notifyApp() {
this.showModal = false;
this.$emit('weaponAdded');
}
},
}
</script>
But when I bind the element dwarf to the Child Component <app-modal/> it changes to the next dwarf in the array dwarfs (TEST) - (So as the result when i add a new weapon in the modal-form it gets added to the second dwarf...):
Child_Component.vue :
<template>
<div>
<div class="myModal" v-show="showModal">
<div class="modal-content">
<span #click="$emit('close')" class="close">×</span>
<h3>Neue Waffe</h3>
<!-- TEST -->
<p>{{ targetDwarf }}</p>
<form>
<input
type="text"
placeholder="Name..."
v-model="weaponName"
required
/>
<input
type="number"
placeholder="Magischer Wert..."
v-model="magicValue"
required
/>
<button #click.prevent="onClick">bestätigen</button>
</form>
</div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
weaponName: '',
magicValue: '',
}
},
props: ['showModal', 'targetDwarf'],
methods: {
onClick() {
if(this.weaponName !== '' &&
Number.isInteger(+this.magicValue)) {
let newData = {...this.dwarf};
newData['weapons'] = [
...this.dwarf['weapons'],
{
"name": this.weaponName,
"magicValue": Number.parseInt(this.magicValue)
},
];
this.$http.post("https://localhost:5019/api", newData)
.then(data => data.text())
.then(text => console.log(text))
.catch(err => console.log(err));
this.$emit('weaponAdded');
} else {
alert('You should fill all fields validly')
}
},
}
}
</script>
It looks like you have the <app-modal/> component inside of the v-for="dwarf in dwarfs" loop, but then the control for showing all of the modal components created by that loop is just in one variable: showModal. So when showModal is true, the modal will show each of the dwarfs, and I'm guessing the second dwarf's modal is just covering up the first one's.
To fix this, you could move the <app-modal /> outside of that v-for loop, so there's only one instance on the page, then as part of the logic that shows the modal, populate the props of the modal with the correct dwarf's info.
Something like this:
<div class="card-container">
<div class="card" v-for="dwarf in dwarfs" :key="dwarf.name">
<p>{{dwarf}}</p>
<div class="card-body">
<button
class="card-button"
#click="() => setModalDwarf(dwarf)"
>
Waffe
</button>
</div>
</div>
<!-- Move outside of v-for loop -->
<app-modal
:showModal="!!modalDwarfId"
:targetDwarf="modalDwarfId"
#close="modalDwarfId = null"
#weaponAdded="onDwarfWeaponAdd"
/>
</div>
export default {
//....
data: () => ({
modalDwarfId: null,
)},
methods: {
setModalDwarf(dwarf) {
this.modalDwarfId = drawf.id;
},
onDwarfWeaponAdd() {
//...
}
},
}
You could then grab the correct dwarf data within the modal, from the ID passed as a prop, or pass in more granular data to the modal so it's more "dumb", which is the better practice so that the component isn't dependent on a specific data structure. Hope that helps
Courtesy of #Joe Dalton's answer, a bit alternated for my case:
<div class="card" style="width: 18rem;" v-for="dwarf in dwarfs" :key="dwarf.name">
...
<button class="card-button" #click="setModalDwarf(dwarf)"><span class="plus-sign">+</span> Waffe</button>
<div>
<app-modal
:showModal="showModal"
:targetDwarf="currentDwarf"
#close="showModal = false"
#weaponAdded="notifyApp"
/>
<script>
import Modal from './NewWeaponModal.vue';
export default {
data() {
return {
showModal: false,
currentDwarf: null,
}
},
components: { appModal : Modal },
props: ['tribeName', 'dwarfs'],
methods: {
setModalDwarf(dwarf) {
this.currentDwarf = dwarf;
this.showModal = true;
},
...
}

I have problems accessing this "name" property on the component. I can only access it statically.
<template>
<div class="col-md-12">
<p
v-for="channel in channels"
:key="channel.id"
class="channel"
:class="{ 'active': channel.id == activeChannel }"
#click="setChannel(channel.id)">
{{ channel.users[0].name }}
</p>
</div>
</template>
Here is an Image of my Vue Devtools
So I have an v-for loop over channels, and I want to: Access the Usernames for each channel (if it is not my own preferably as "username" is set on my own i think its easy to exclude it right?) So that in the end In Channel 1 when there are 2 Users , I want to show the corresponding username, so the "other username", the one i am chatting with, and he should see my name that is the initial goal.
I thought of doing something like this:
<template>
<div class="col-md-12">
<p
v-for="channel in channels"
:key="channel.id"
class="channel"
:class="{ 'active': channel.id == activeChannel }"
#click="setChannel(channel.id)">
<!-- {{ channel.users[0].name }} -->
<span v-for="user,key in channel">{{key}}</span>
</p>
</div>
it at least displays the content of the channels object for each channel, but something like this isnt gonna work: key.user.name , unfortunately im stuck here. please help :)
edit: here is a dd() of the view
click

console.log("received message");

//ChatController.php
public function index()
{
$channels = Channel::with('users')->whereHas('users', function($q) {
$q->where('user_id',Auth::id());
})->get();
$user = Auth::user()->name;
return view('chat-app' , compact('channels','user'));
}
Short Explanation: ChatController returns the blade view, which has the data channels and user (my username) , and then vue comes into play which should pass down the prop of my username but i couldnt get it to work just yet
So you need to access users in every channel.
You can try like this:
<div class="col-md-12">
<p
v-for="channel in channels"
:key="channel.id"
class="channel"
:class="{ 'active': channel.id == activeChannel }"
#click="setChannel(channel.id)">
<span v-for="user in channel.users">
{{ user.name }}
</span>
</p>
</div>
This should work. If you have errors provide it here.
If you need to compare every user you can do it simply with v-if:
<span v-for="user in channel.users">
<span v-if="user.name === parentdata">
{{ user.name }}
</span>
</span>
I am using Vuejs cdn. In which I have a Navigation menu. I want to load different layout when a user clicks on Nav menu.
for example
<div class="row" id="mytemplate">
<div class="col-sm-3 sidebar-col">
<div>
<nav class="settings-sidebar">
<h4>Profile settings</h4>
<ul>
<li class="active" v-on:click="Profile()">
<a >Profile picture</a>
</li>
<li class="" v-on:click="Business()">
<a >Business details</a>
</li>
<li class="" v-on:click="Equipments()">
<a >Equipments details</a>
</li>
</ul>
</nav>
</div>
</div>
<div class="col-sm-9 col-xs-12 settings-body">
{{ load_layout_here }}
</div>
Now when user click on "Business Details" option it should run function Business() and load layout from business.html or business.php
the sample code in business.php
<div class="form">
<div class="input-field">
<h5>Business name</h5>
<input type="text" class="textbox" name="primary-phone" value="Perfect choice movers" placeholder="Your business name" maxlength="15">
</div>
<div class="input-field inline-input">
<h5>City</h5>
<input type="text" class="textbox " name="business-city" value="myCity" placeholder="Business address" maxlength="15">
</div>
<button class="btn btn-orange" type="submit">Save</button>
My vue.js code is
var app2 = new Vue({
el: '#mytemplate',
data : {
message : 'hi',
},
methods: {
Profile : function () {
this.message = 'Profile';
},
Business : function () {
// Here I want to call Html Template to load seprate layout
this.message = 'Business';
},
Equipments : function () {
this.message = 'Equipments';
}
}
})
I have seen lots of answers on the internet but they all using vue template engine or .vue files. Which I do not want to use
Note : I am using CodeIgniter as PHP framework. and Vue for frontend.
You can use axios to render the html. What ever data come in response data variable. That should to show.
Profile : function () {
axios.get('profile.php')
.then(function (response) {
console.log(response.data);
// response
this.message = response.data.json;
})
.catch(function (error) {
// handle error
console.log(error);
});
}
and to use axios, you have to include cdn file.
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
