I am very new in karma jasmine test case. please help me out.
Typescript
import { Component, OnInit, ViewChild } from '#angular/core';
#Component({
selector: 'app-label',
templateUrl: './app-label.component.html',
})
export class LabelRenderer implements OnInit {
moreInfoItems;
#ViewChild('moreInfoModal') moreInfoModal;
constructor() { }
ngOnInit(): void { }
showModal(labelMenu) {
this.moreInfoItems = labelMenu?.content;
this.moreInfoModal.open();
}
}
HTML
<div
#moreInfoModal
[closeButton]="true"
>
<h2>More Information</h2>
<div class="modal-content">
<ul
data-size="large"
>
<li *ngFor="let item of moreInfoItems">
<div class="_text-bold _text-underline">{{item.heading}}</div>{{item.description}}
</li>
</ul>
</div>
</div>
I want to write unit test case for same but facing issue. Below code I tried for same.
it('should validate showModal method', () => {
component.moreInfoItems = {
content: [
{
"heading": "",
"description": ""
}
]
};
spyOn(component.moreInfoModal, 'open').and.returnValue({});
component.moreInfoModal.open();
expect(component.moreInfoModal.open).toHaveBeenCalledTimes(1);
spyOn(component, 'showModal').and.callThrough();
component.showModal(component.moreInfoItems);
expect(component.moreInfoItems).toHaveBeenCalled();
});
I saw some solution on stack overflow but most of the solutions I see with modal component. so request to help me out.
Thanks in advance.

i am new to Vue JS, i must say i really love this platform. I started using it just 3 days back. I am just trying to get the URL query parameter and i am using vue-router as well. Here is how i have it:
http://localhost:8001/login?id=1
Here is how my controller look like.
<template>
<section class="contact-info-area">
<div class="container">
<div class="row">
<div class="col-lg-12">
<section class="write-massage-area">
<div class="mb-5"></div>
<div class="row justify-content-center">
<div class="col-lg-5">
<div class="write-massage-content">
<div class="write-massage-title text-center">
<h3 class="title">Login {{ $route.query.id }}</h3> <!-- THIS IS WORKING -->
</div>
<div class="write-massage-input">
<form #submit.prevent="onSubmitForm">
<div class="row">
<div class="col-lg-12">
<div class="input-box mt-10">
<input type="text" placeholder="Email" v-model="form['email']">
<ErrorMessage :validationStatus="v$.form.email"></ErrorMessage>
</div>
</div>
<div class="col-lg-12">

</template>
<script>
import { ref } from 'vue'
import useVuelidate from '#vuelidate/core'
import { required, minLength, email } from '#vuelidate/validators'
import ErrorMessage from '../components/ErrorMessage'
export default {
name: "login",
components: {
ErrorMessage
},
created(){
},
setup(){
const form = ref({})
const rules = {
form: {
email: {
required,
email
},
password: {

minLength : minLength(5)
}
}
}
const v$ = useVuelidate(rules, { form })
function onSubmitForm(){
console.log(this.$route.query.id) **<!-- THIS IS NOT WORKING -->**
v$.value.$touch()
console.log(form.value)
}
return { form, onSubmitForm, v$}
}
}
</script>
here on the above code. On button submit i am going to a function called onSubmitForm, there i am using console.log(this.$route.query.id) but this is giving a below error :
Uncaught TypeError: Cannot read property 'query' of undefined
at Proxy.onSubmitForm (Login.vue?a55b:84)
Why this is happening? I am seeing that in the vue document as well, they mentioned in the same way. What i am missing in this?
Thank you!
You can call useRoute to access the query params...
<script setup>
import { useRoute } from 'vue-router'
const route = useRoute()
console.log(route.query)
</script>
If you use parameters and your endpoint looks something like this:
{
path: '/inspect_detail/:id',
name: 'inspect_detail',
component: function() {
return import ( '../views/Inspect_detail.vue')
},
params: true
},
and you are routing like this:
<router-link :to="{ name: 'inspect_detail', params: { id: akey }}">...</router-link>
then you can pickup the values like this:
<script>
import { useRoute } from 'vue-router';
export default {
setup(){
const route = useRoute()
console.log( route.params );
}
}
</script>
Bit late but if you want query params to work on page refresh you have to wait for the router to get ready as its asynchronous. The router wont be ready if its a page refresh. The router will be ready if its navigation from another page in that case the query params will be available from the begining.
<script setup>
import { onMounted } from 'vue'
import { useRouter, useRoute } from 'vue-router'
const router = useRouter()
const route = useRoute()
//just to demonstrate
console.log(route.query)
// If it is a page refresh it will print null.
// The router wont be ready if its a page refresh. In that case the query wont be available.
// The router will be ready if its navigation from another page in that case the query params will be available
onMounted(() => {
getUrlQueryParams()
});
getUrlQueryParams = async () => {
//router is async so we wait for it to be ready
await router.isReady()
//once its ready we can access the query params
console.log(route.query)
});
</script>
I hadn't done frontend in a couple of months and had to refresh on Vue 3 and route query properties, and this question came up first.
Now the memory jog has kicked in, I believe the correct way is to pass the props from the router to the component as shown in the examples here https://router.vuejs.org/guide/essentials/passing-props.html
Essentially, call your route
{
path: "/login",
name: "Login",
props: route => ({ id: route.query.id }),
component: () => import(/* webpackChunkName: "login" */ "../views/Login.vue"),
},
to be able to access the id field.
Alternately, you can sent the whole lot with props: route => ({ query: route.query })
Pick it up as a prop in your view/component
export default {
name: "login",
components: {
ErrorMessage
},
created(){
},
props: {
id: {
type: String,
default: "",
}
}
setup(props){
const form = ref({})
const rules = {
form: {
email: {
required,
email
},
password: {
required,
minLength : minLength(5)
}
}
}
const v$ = useVuelidate(rules, { form })
function onSubmitForm(){
console.log(props.id)
v$.value.$touch()
console.log(form.value)
}
return { form, onSubmitForm, v$}
}
}
I have posts and replys s.t. replies belong to posts via the attribute reply.posts_id.
I am attempting to show the reply form as a modal for the user to enter a reply. However, I want to create a generic Modal component that I can use everywhere with content that is specified in another component built for a specific context.
Reply to post is the first place I woul like this to work.
Currently, the Vuex correctly returns Modal visible:true when the reply button is clicked, but the modal does not render and I get the error message showing that the Modal component is not found:
Unknown custom element: <ModalReplyForm> - did you register the component correctly? For recursive components, make sure to provide the "name" option.
I am using vuex to manage the visibility of the modal. Here are the relevant files:
store.js:
import Vue from 'vue'
import Vuex from 'vuex'
import axios from 'axios'
...
Vue.use(Vuex)
export default new Vuex.Store({
state: {
status: '',
...
modalVisible: false,
modalComponent: null
},
mutations: {
...
showModal(state, componentName) {
console.log('showing the modal')
state.modalVisible = true;
state.modalComponent = componentName;
},
hideModal(state) {
console.log('hiding the modal')
state.modalVisible = false;
}
},
actions: {
...
}
},
getters: {
isAuthenticated: state => !!state.user,
authStatus: state => state.status,
user: state => state.user,
token: state => state.token,
posts: state => {
return state.posts;
}
...
}
})

Unknown custom element: - did you register the
component correctly? For recursive components, make sure to provide
the "name" option.
This message says that you never imported/defined ModalReplyForm, which you have not.
In my own generic modal, I ended up having to import all the components that might appear within the modal itself.
If you add a:
import ModalReportForm from ...
and a:
components: {
ModalReplyForm
}
to AppModal.vue, the modal should then do what you expect.
Good afternoon, tell me please, I wrote a calendar displaying the events that the user sets, and now I want to make a detailed display of the event when I click it. The problem is that the events are in my component and the whole display logic is in another, how can I use them together.I want to make it so that the getDetailInformation() function in the ModalWindowDetail component component is called by clicking on an event in another component Calendar.vue. I use the event bus, but nothing works for me, I don’t understand why. Please help me solve this problem.

console.log(this.memo)
if(memo === this.eventText){
let dataStartOfEvent = arrOfEvents[z].starts_at;
let getStartDataOfEvent = new Date(dataStartOfEvent);
let dataEndOfEvent = arrOfEvents[z].ends_at;
let getEndDataOfEvent = new Date(dataEndOfEvent);
if((getStartDataOfEvent.getHours() - 3) > 0){
this.$store.commit('changeModalWindowDetail', this.modalWindowDetail);
this.eventDetail = {
'Событие': this.eventText,
'Начало события': getStartDataOfEvent.toLocaleTimeString(),
'Конец события': getEndDataOfEvent.toLocaleTimeString(),
'Тип события': this.getType(arrOfEvents[z].type)
}
}else if(getStartDataOfEvent.getDate() != getEndDataOfEvent.getDate()){
this.$store.commit('changeModalWindowDetail', this.modalWindowDetail);
this.eventDetail = {
'Событие': this.eventText,
'Начало события': getStartDataOfEvent.toLocaleDateString(),
'Конец события': getEndDataOfEvent.toLocaleDateString(),
'Тип События': this.getType(arrOfEvents[z].type)
}
}
}
}
}
}
};
</script>
You should remove the () from the function name in eventBus.$on('getDetailInformation', this.openModalDetail()) - you want to reference the function, not to call it and use the result as a reference.
Also, your function getDetailInformation() does not return anything - but you seem to expect that it returns a text. You should correct this.
And finally, I think that #sendTextEvent="text = arguments[0]" would be more appropriate - and using a dedicated method/function will be the best.

My goal is that I want to get $('.synonym-list').width() in synonym.vue file so I can change it for all child component in parent component, but I don't know how to manage it.I checked document theres no hook for it. If u have any idea please tell me, thanks!
Use events.
<carousel #update="onCarouselUpdate" :synonyms="synonymGroup.synonyms"></carousel>
...
export default {
components: { ... },
mounted () { ... },
methods: {
onCarouselUpdate () {
console.log('Carousel Updated!')
}
}
}
synonym-carousel:
export default {
updated () {
this.$emit('update')
}
}
docs: https://v2.vuejs.org/v2/guide/components.html#Custom-Events
synonym.js
<li v-for="(synonymGroup, i) of synonymGroupList" :key="synonymGroup._id">
<carousel #update="onCarouselUpdate" :synonyms="synonymGroup.synonyms" :isLast="i === (synonymGroupList.length - 1)? true: false"></carousel>
</li>
export default {
components: { ... },
mounted () { ... },
methods: {
onCarouselUpdate () {
console.log('Carousel Updated!')
}
}
}
synonym-carousel:
export default {
mounted() {
if(this.isLast) {
this.$emit('update');
}
}
Based on #CodinCat answer, this is my final resolution. It has the advantage that it does not trigger update for each list-item (since v-for is used) but only for the last one, so when 'everything is ready'.
I have this view:
<template>
<require from="../customElements/spinner.html"></require>
<div class="sub-submenu-wrapper">
<div show.bind="success">

And here is the model:

In summary, I am making a fetch call, getting some data, making a table from it. What i want is to make the HTML data(i.e. table) that I am inserting bindable or connected to my view model. I found some information about Aurelia's enhancement here: http://ilikekillnerds.com/2016/01/enhancing-at-will-using-aurelias-templating-engine-enhance-api/ but i have trouble figuring out how to integrate this with my own code.
Overview
Prerequisite: have some already-working aurelia app
Import the TemplatingEngine
Insert your dynamic html into the DOM (e.g. via .innerHTML)
Call TemplatingEngine.enhance(config) with proper configuration
Details
Prerequisite - Create the skeleton:
au new enhance_test
I'm using the minimal example, using the skeleton provided in Aurelia CLI.
The actual code:
app.html:
<template>
<h1>${message}</h1>
<div id="content-div"></div>
</template>
app.ts:
import {autoinject, TemplatingEngine} from 'aurelia-framework';
#autoinject
export class App {
message = 'Hello World!';
constructor(private _templEngine: TemplatingEngine) { }
attached() {
let contentDivElem = document.getElementById("content-div");
contentDivElem.innerHTML = "<button>TEST ${message}</button>"; //inserting your dynamic HTML
let elemView = this._templEngine.enhance({ element: contentDivElem, bindingContext: this}); //binding the element to the instance of App
}
}
