i have this HTML for show list of users :
<div *ngFor="let item of users " [ngClass]="{'highlight': item.isDeleted }"
class="d-flex selected-list-items mt-3">
<div class="col-md-5 col-lg-5 col-xs-5 col-sm-5 col-xl-5">
<label>{{item.displayName}}</label>
</div>
<div class="col-md-5 col-lg-5 col-xs-5 col-sm-5 col-xl-5">
<label> {{ getEnumTranslate(item.title)}}</label>
</div>
<div class="justify-content-center col-md-2 col-lg-2 col-xs-2 col-sm-2 col-xl-2">
<button (click)="deleteUser(item.userId)" mat-button>
<mat-icon aria-label="Delete" color="accent">delete</mat-icon>
</button>
</div>
</div>
and i create a validation with private transport: BehavorSubject, for do this :
when the transport is changes must be execute this code :
this.transport.listValue$.subscribe(data => {
if (data != null) {
data.forEach(element => {
let user = this.users.find(x => x.userId = element);
if (user != null) {
user.isDeleted = true;
}
});
}
});
and in html change the background color of find user in this code let user = this.users.find(x => x.userId = element); .
now my problem is here :
when transport is change it run code for change background and find that user but it just change background of first element in this HTML code , specific user in the Third element but it change first element In the event that need change Third element in HTML .
how can i solve this problem ?
I have updated the code that should work for your scenario. Here I am mutating the actual data inside users array. Please check and let me know if it resolves your issue.
this.transport.listValue$.subscribe(data => {
if(data != null) {
for (const user of this.users) {
if(data.includes(user.userId)) {
user.isDeleted = true
}
}
}
});

I have made a TODO app and added a counter to keep a count of the items in the list. If the counter hits zero, I've set it to re-show a message 'You currently have no tasks. Use the input field above to start adding.'
if(count === 0){
noTasksText.classList.remove('d-none');
}
In the console I print out the div and it doesn't have d-none in the class list any more which is what I want, however, in the actual DOM it does.
Here is a full example - https://codepen.io/tomdurkin/pen/LYdpXKJ?editors=1111
I really can't seem to work this out. I can't seem to interact with that div when the counter becomes zero, however I can get console logs etc to show when expected.
Any help would be appreciated!

Upon setting innerHTML by using += innerHTML the node noTasksText is lost, because browser processes the whole new set innerHTML and creates new objects. You can either retrieve noTasksText again after that, or append nodes using todoContainer.appendChild. I forked your pen and solved it with the latter solution.
https://codepen.io/aghosey/pen/wvmGwWd
You can do the following, it will work (here innerHTML is changing the DOM, so I added an extra function to recalculate elements after DOM is changed due to innerHTML):
var mainInput = document.querySelector("#main-input");
var todoContainer = document.querySelector("#todo-container");
var errorText = document.querySelector("#js-error");
var noTasksText = document.querySelector(".js-no-tasks");
let tasks = [];
let count = 0;
function getAllElements() {
mainInput = document.querySelector("#main-input");
todoContainer = document.querySelector("#todo-container");
errorText = document.querySelector("#js-error");
noTasksText = document.querySelector(".js-no-tasks");
}
// focus input on load
window.onload = () => {
mainInput.focus();
var storedTasks = JSON.parse(localStorage.getItem("tasks"));
if (storedTasks != null && storedTasks.length > 0) {
// set count to number of pre-existing items
count = storedTasks.length;
// hide the 'no tasks' text
noTasksText.classList.add("d-none");
// overwrite tasks array with stored tasks
tasks = storedTasks;
tasks.forEach((task) => {
// Build the markup

I want to filter my checkboxes I search it on internet there was information but I couldn't work it with my code.
This is the webpage
I want when you click on the checkbox it must be same as the category.
This is some code of the checkbox:
<div>
<input class="form-check-input checkboxMargin" type="checkbox" value="All" v-model="selectedCategory">
<p class="form-check-label checkboxMargin">All</p>
</div>
This is my grey box layout:
<div class="col-sm-12 col-md-7">
<div class="card rounded-circle mt-5" v-for="item of items" :key="item['.key']">
<div>
<div class="card-body defaultGrey">
<h5 class="card-title font-weight-bold">{{ item.name }}</h5>
<div class="row mb-2">
<div class="col-sm ">
<div class="row ml-0"><h6 class="font-weight-bold">Job:</h6><h6 class="ml-1">{{ item.job }}</h6></div>
<div class="row ml-0"><h6 class="font-weight-bold">Category:</h6><h6 class="ml-1">{{ item.categories }}</h6></div>
<div class="row ml-0"><h6 class="font-weight-bold">Location:</h6><h6 class="ml-1">{{ item.location }}</h6></div>
<div class="row ml-0"><h6 class="font-weight-bold">Niveau:</h6><h6 class="ml-1">{{ item.niveau }}</h6></div>
<div class="row ml-0"><h6 class="font-weight-bold">Availability:</h6><h6 class="ml-1">{{ item.availability }}</h6></div>
<h6>{{ item.info }}</h6>
<div class="row ml-0"><h6 class="font-weight-bold">Posted:</h6><h6 class="ml-1">{{ item.user }}</h6></div>
</div>
</div>
<div class="row">
<div class="col-xs-1 ml-3" v-if="isLoggedIn">
<router-link :to="{ name: 'InternshipDetails', params: {id: item['.key']} }" class="btn bg-info editbtn">
Details
</router-link>
</div>
<div class="col-xs-1 ml-3 mr-3" v-if="isLoggedIn && item.user == currentUser">
<router-link :to="{ name: 'Edit', params: {id: item['.key']} }" class="btn btn-warning editbtn">
Edit
</router-link>
</div>
<div class="col-xs-1" v-if="isLoggedIn && item.user == currentUser">
<button #click="deleteItem(item['.key'])" class="btn btn-danger dltbtn">Delete</button>
</div>
</div>
</div>
</div>
</div>
</div>
And I have my object here but how can I filter my grey boxes with category:
selectedCategory: []
Use computed properties:
computed: {
filteredItems(){
if(this.selectedCategory.length == 0) return this.items;
return this.items.filter(el => {
for(let i = 0; i < this.selectedCategory.length; i++){
if(el.categories == this.selectedCategory[i]) return el;
}
});
}
}
Then you go for v-for="item of filteredItems"
I didnt tested it. If you provide me more code i could help you more
You need to create one-way binding between your CategoryCheckBox component and your ListCard component.
Because you provided separated code when I can not reproduce it to give you a solution based on your own, I suggest this example to explain my solution.
Step One:
You have many ways to CRUD your items using a Plugins or Vuex or global instance, in my example I used global instance in main.js
Vue.prototype.$myArray = ["Books", "Magazines", "Newspaper"];
I assume you created your items data in the ListCards component
Step Two:
You need to add #change event in your checkbox to handle checked and unchecked states. I used static data (Book) for value.
<label>
<input type="checkbox" value="Books" #change="handleCategory($event)" /> Books
Now, let's implement handleCategory method, but before that, as we know that Checkbox and ListCards are independents which means we need to define a bus to create event communication between them and this is your issue so we define the bus inside the main.js
Vue.prototype.$bus = new Vue({});
Now we define handleCategory like this :
methods: {
handleCategory(e) {
this.$bus.$emit("checkCategory", e);
}
}
Step Three:
How can our ListCards listen to this event ?
By call $bus.$on(..) when the component is created ( Hope you know what Vue lifecycle methods mean )
created() {
this.$bus.$on("checkCategory", e => this.checkCategory(e));
},
When the user click the check box the component runs handleCategory then runs checkCategory inside ListCard.
Inside my ListCard, I have categories and originalCategories as data
data() {
return {
categories: this.$myArray,
originalCategories: this.$myArray
};
},
and a template :
<ul v-for="(category,index) in categories" :key="index">
<CategoryItem :categoryName="category" />
</ul>
and a created method ( lifecycle )
created() {
// $bus is a global object to communicate between components
this.$bus.$on("checkCategory", e => this.checkCategory(e));
},
and our filtering methods :
methods: {
checkCategory(e) {
let target = e.target;
let value = e.target.value;
target.checked
? this.filterCatergories(value)
: (this.categories = this.originalCategories);
},
filterCatergories(value) {
this.categories = this.categories.filter(val => val === value);
}
}
What's important for you is :
this.categories.filter(val => val === value); //will not do nothing
const categories=this.categories.filter(val => val === value); //will update the view.
And you can change the code or make it better and simple.
#Update
You can also use computed properties but because we have a parameter here which is the category name we need get and set.
computed: {
filteredItems: {
get: function() {
if (this.selectedCategory.length == 0) return this.items;
return this.items.filter(value => {
for (const category of this.selectedCategory) {
if (value == category) return value;
}
});
},
set: function(category) {
this.selectedCategory.push(category);
}
}
},
methods: {
checkCategory(e) {
let target = e.target;
let value = e.target.value;
target.checked
? (this.filteredItems = value)
: this.selectedCategory.pop(value);
}
}
I am making angular application with angular dynamic form where i am using ng-select library.

Here the [items]="templateList" has the following,
[{"id":"5bebba2c20ccc52871509d56","name":"Template One"},
{"id":"5bebba5720ccc52871509d57","name":"Template Two"},
{"id":"5bebba8d20ccc52871509d5d","name":"Template Three"}]
I am having (change)="getTemplateValues($event)" event for detecting each change happen when we select an item from dropdown.
The change event function Edited,
getTemplateValues(e) {
this.dynamicFormService.getRest("url" + '/' + e.id").subscribe(res => {
try {
if (res.status === "true") {
res.data.template_properties.forEach(element => {
this.templateArray.push(element);
});
this.form = this.qcs.toFormGroup(this.questions);
for (let i = 0; i < this.templateArray.length; i++) {
this.addControls('template_properties');
}
let propertiesArray = [];
this.templateArray.forEach(element => {
propertiesArray.push(element);
});
this.form.patchValue({
'template_properties': propertiesArray
});
} else {
}
}
catch (error) {
}
})
}
console.log(this.propertiesArray) gives the following,
[{"property_name":"Property one","property_type":4,"property_required":true,"property_origin":1},{"property_name":"Property one","property_type":5,"property_required":true,"property_origin":1}]
In the below image i have deleted template three but the template three properties still showing in it..
Here first i am filtering the data first and ignoring the duplicates and each time i am sending the newly selected values alone to the service and fetching the data related to the id element.id.
And using this.addControls('template_properties') to make open the number of rows, and elements will get patched to the form template_properties.
this.form.patchValue({
'template_properties': propertiesArray
});
As of now everything working fine..
The problem actually arise from here:
If we delete a selected list from dropdown, (say i have selected all three template and i have deleted the template two then that particular template's template_properties needs to get deleted..
I have tried with (remove)="onRemove($event)" but its not working because while remove data, the (change) function also calls..
How can i remove the template_properties with this.removeControls('template_properties'); of particular deleted template name in the change event or remove event..
Remove Function:
onRemove(e) {
console.log(e);
this.dynamicFormService.getRest("url" + '/' + e.value.id").subscribe(res => {
try {
if (res.status === "true") {
for (let i = 0; i < res.data.template_properties.length; i++) {
this.removeControls('template_properties');
}
} else {
}
}
catch (error) {
}
})
}
Remove Control:
removeControls(control: string) {
let array = this.form.get(control) as FormArray;
console.log(array)
array.removeAt(array.length);
}
console.log(array) gives,
It should be pretty easy fix. Use (add) instead of (change) in ngi-select.
onRemove(e) {
console.log(e);
this.dynamicFormService.getRest("url" + '/' + e.value.id").subscribe(res => {
try {
if (res.status === "true") {
this.form = this.qcs.toFormGroup(this.questions);
// Issue is here, you should remove only specific record
// which is being passed from function `e`
for (let i = 0; i < res.data.template_properties.length; i++) {
this.removeControls('template_properties');
}
let propertiesArray = [];
this.templateArray.forEach(element => {
propertiesArray.push(element);
});
this.form.patchValue({
'template_properties': propertiesArray
});
} else {
}
}
catch (error) {
}
})
}
Pass the index in removeControls where you want to remove the element from.
removeControls(control: string, index:number) {
let array = this.form.get(control) as FormArray;
console.log(array)
array.removeAt(index);
}
console.log(array) gives,
I'm working on a system where the user can select a product and go to the next page. This product then gets saved in the session using laravel sessions. When the user decides to go to the next page and come back. The chosen product is indeed saved in the session, but the is no way for them to see what product they have chosen because the class isn't applied to the product that was chosen.
The code may clarify it better:

if(cardId === null) {
cardId = newSelectedCardId;
} else if (cardId !== newSelectedCardId) {
$('#theme-id-' + cardId).removeClass('theme-chosen').find("input[name='theme["+cardId+"]']").val('');
cardId = null;
}
var card = $('#theme-id-' + cardId );
card.toggleClass('theme-chosen');
selectedCardInput = card.find("input[name='theme["+cardId+"]']");
if( !$('.theme-card').hasClass('theme-chosen') ) {
selectedCardInput.val('');
} else if ( $('.theme-card').hasClass('theme-chosen') ) {
selectedCardInput.val('selected');
}
console.log(selectedCardInput);
});
Here I add the class to the card so the user can See which card they've selected. This choice then gets saved in the session using some PHP code in the controller
if( $theme == null ) {
return redirect('plugins');
} elseif( $theme != null ) {
foreach($this->predefinedArray as $value) {
$request->session()->put('chosen_theme.' . $value, $theme->$value);
}
$request->session()->put('chosen_theme.composer_package', $theme->productable->composer_package);
return redirect('plugins');
}
problem
How can I read the session and add the class to the card with the IDs that were stored in the session so if the person leaves the page and comes back, they can see what cards they've selected?
Thanks in advance
Try this in your view..
<div class="card theme-card card-hover depth-2 border-0 {{ \Session::get('chosen_theme.composer_package') == $theme->id ? 'theme-chosen' : '' }}" id="theme-id-{{$theme->id}}">
Whenever the theme id is in the session and the page loaded the class will be added, and if it is not in the session then the class won't be added.
Let me know the result..
I'm using Vue v2
I'm trying to change only the properties of the selected element. See, when the response is marked after the click, it should change to a red color with a text that says 'Unmark'. And vice versa: if the button is clicked again (which now would say 'Unmark'), it should change to a green color and the text would be 'Mark'. Alas, it works.... Nevertheless, my code applies the change to every element inside the v-for; I only want that to happen to the selected element.
I've thought about using a Component to check if somethings changes, but first I'd like to see if there's a solutions for this. ANy help will be appreciated
Here's my code:
<div class="search-results">
<div class="activity-box-w" v-for="user in users">
<div class="box">
<div class="avatar" :style="{ 'background-image': 'url(' + user.customer.profile_picture + ')' }">
</div>
<div class="info">
<div class="role">
#{{ '#' + user.username }}
</div>
<div>
<div>
<p class="title">#{{ user.customer.name }}
#{{user.customer.lastname}}
</p>
</div>
</div>
</div>
<div class="time">
<input type="button" class="btn btn-sm btn-primary" v-on:click.prevent="markUser(user)" v-model="text"
v-bind:class="[{'green-border':notMarked}, {'red-border':marked}]" v-cloak v-if="!action"
:disabled="action"></input>
</div>
</div>
</div>
Now for the script:
new Vue({
el: '#engage-panel',
data: {
users: [],
mark: {'id' : '', 'marks' : ''},
text: 'Mark', //Migth change to Unmark later on
action: false,
marked: null,
notMarked: null,
},
methods:
{
markUser: function(user){
this.mark.id = user.id;
this.action= true;
Vue.http.headers.common['X-CSRF-TOKEN'] = $('meta[name="csrf-token"]').attr('content');
this.$http.put('/mark/user', this.mark).then(response => {
if(response.body === "marked")
{
this.mark.marks="true";
this.text = 'Unmark';
this.marked= true;
this.notMarked= false;
this.action= false;
}else{
this.mark.marks="false";
this.text = 'Mark';
this.marked= false;
this.notMarked= true;
this.action= false;
}
}).catch(e => {
this.action= false;
});
}
}
You can use $event.target on click if you just need to toggle css class.

But it's true that it's easier if a user has a status like marked = true/false for example, you just need to bind class like :
<input :class="{ 'green-border': user.marked, 'red-border': !user.marked }">
The issue my code applies the change to every element you met is caused by every user in v-for="user in users" uses one same object to indicates it is marked or not.
If your users data has one property like status to save current status (like unmark, mark etc), it is very simple, just change to next status when click mark button.
If your users data doesn't have that property, you need to create one dictionary, then save the users already clicked as key, the status for the user will be the value.
Below is one demo:
app = new Vue({
el: "#app",
data: {
users1: [{'name':'abc', 'status':'none'},
{'name':'xyz', 'status':'none'}],
users2: [{'name':'abc'}, {'name':'xyz'}],
selectedUsers: {}
},
methods: {
getNextStatusBaseOnRoute: function (status) {
if(status ==='marked') return 'marked'
let routes = {'none':'unmark', 'unmark':'marked'}
return routes[status]
},
markUser1: function (item) {
item.status = this.getNextStatusBaseOnRoute(item.status)
},
markUser2: function (item) {
let status = item.name in this.selectedUsers ? this.selectedUsers[item.name] : 'none'
// remember to use vue.$set when adding new property to one object
this.$set(this.selectedUsers, item.name, this.getNextStatusBaseOnRoute(status))
}
}
})
.marked {
background-color:green;
}
.unmark {
background-color:yellow;
}
<script src="https://unpkg.com/vue#2.5.16/dist/vue.js"></script>
<div id="app">
<h2>Case 1: </h2>
<div v-for="(item, index1) in users1" :key="'1'+index1">
<span>{{item.name}}:</span><span :class="[item.status]">{{item.status}}</span><button #click="markUser1(item)">Mark</button>
</div>
<h2>Case 2: </h2>
<div v-for="(item, index2) in users2" :key="'2'+index2">
<span>{{item.name}}:</span><span :class="[item.name in selectedUsers ? selectedUsers[item.name] : 'none']">{{item.name in selectedUsers ? selectedUsers[item.name] : 'none'}}</span><button #click="markUser2(item)">Mark</button>
</div>
</div>
For Vue3, you can also store the index of the selected element
<ul role="list" class="">
<li class="relative" v-for="(image, index) of images" :class="selectedImage == index? 'border-indigo-500 border-2': 'border-transparent'" >
<div #click="selectedImage = index" class="">
<img :src="image" alt="" class="object-cover pointer-events-none group-hover:opacity-75">
</div>
</li>
</ul>
