I am displaying users in a list with their photo, name etc... and then I am grabbing the value of the element that has the id "uid" :
$scope.toUserView = function() {
var uid = document.getElementById('userUID').textContent;
console.log(uid);
$state.go('tab.userview');
};
Problem is that whoever I click on, I always get the reference of the FIRST user in the list of the page and I would like to grab only the one I click on.
I tried to add .click() at the end of my var but it is not a function.
Any idea ?
EDIT : Corresponding HTML :
<ion-list class="item-border-off list-fav">
<a ><ion-item ng-click="toUserView()" ng-repeat="user in users" class="item-remove-animate item-avatar">
<img ng-src="{{user.photoURL}}">
<h2>
{{user.name}}
</h2>
<p >{{user.description}}</p>
<p id="userUID">{{user.uid}}</p>
<!-- button options -->
<ion-option-button>
<i class="icon ion-ios-trash-outline"></i>
</ion-option-button>
<ion-option-button>
<i class="icon ion-ios-chatbubble-outline"></i>
</ion-option-button>
</ion-item></a>
</ion-list>
Corresponding HTML
<a ><ion-item ng-click="toUserView($index)" ng-repeat="user in users" class="item-remove-animate item-avatar">
<img ng-src="{{user.photoURL}}">
<h2 id={{user.uid}}>
{{user.name}}
</h2>
<p >{{user.description}}</p>
<p id="userUID{{$index}}">{{user.uid}}</p>
<!-- button options -->
<ion-option-button>
<i class="icon ion-ios-trash-outline"></i>

JS
$scope.toUserView = function(ind) {
var uid = document.getElementById('userUID'+ind).textContent;
console.log(uid);
$state.go('tab.userview');
};
You seem to repeat the <p id="userUID"></p> in a loop.
id attributes should be unique to a page by definition.
document.getElementById('test') returns the first element having the id attribute set to test.
You should either add something unique to your ids, or use class="userUID" instead.

<div
[ngClass]="{ 'template-row': !isExpandable, 'folder-row': isExpandable }"
class="label-with-icons clickable"
(click)="expanderClicked()"
(click)="itemSelected()"
>
<i *ngIf="isExpandable" [ngClass]="getArrowIconClass()"></i><i [ngClass]="getIconClass()"></i>
<span *ngIf="id" class="name ">{{ name }}</span>
<span *ngIf="!id" class="name">{{ name }}</span>
<i *ngIf="!isExpandable" class="io-icon-trash clickable" id="delete" (click)="deleteTemplate()"></i>
</div>
I want the entire div to be clickable but not the icon with id= delete. I want to have a different click event on that
I dont use jquery , i work with TS
You can stop the event to propagate up in the DOM tree with event.stopPropagation() :
(click)="deleteTemplate($event)"></i>
deleteTemplate(e: Event) {
e.stopPropagation(); // <----event won't travel up
}
Goal: Change style of an element in a forEach loop
Issue: Style not being applied
In my loop, if I console.log(element), I do get the right list of filtered elements.
Running this works, but I want my function to modify every element that match my filter:
let contentPreview = document.querySelectorAll('.o_last_message_preview');
contentPreview[0].style.color = 'yellow'
All elements are correctly assigned.
function changeNotificationColor() {
// Notification button that opens list of notifications
let notifyButton = document.querySelector('.dropdown-toggle.o-no-caret[title="Conversations"]');
notifyButton.addEventListener('click', function () {
// List of notifications - each notification is contained in a .o_last_message_preview class
let contentPreview = document.querySelectorAll('.o_last_message_preview');
contentPreview.forEach(function (element) { if (element.innerText.includes('Marine')) {element.style.color = 'yellow'}})
})
}
changeNotificationColor();
HTML Notifications Dropdown button:
<a class="dropdown-toggle o-no-caret" data-toggle="dropdown" data-display="static" aria-expanded="true" title="Conversations" href="#" role="button">
<i class="o_mail_messaging_menu_icon fa fa-comments" role="img" aria-label="Messages"></i> <span class="o_notification_counter badge badge-pill">366</span>
</a>
HTML template of a notification node (each notification creates one of these nodes):
<div class="o_preview_info">
<div class="o_preview_title">
<span class="o_preview_name">
You have been assigned to Backorder xx
</span>
<span class="o_preview_counter">
(1)
</span>
<span class="o_last_message_date ml-auto mr-2"> 3 minutes ago </span>
</div>
<div class="o_last_message_preview">
Marine
</div>
<span title="Mark as Read" class="o_discuss_icon o_mail_preview_mark_as_read fa fa-check"></span>
</div>
I don't know what your issue is, but it's not in the code that you showed; this works fine:
let contentPreview = document.querySelectorAll('.o_last_message_preview');
contentPreview.forEach(function (element) { if (element.innerText.includes('Marine')) {element.style.color = 'yellow'}})
<div class="o_last_message_preview">This contains Marine</div>
<div class="o_last_message_preview">This does not</div>
<div class="o_other_message_preview">This has a different class</div>
I'm working in contact card. I need to add Name and contact number in the list. But the condition is Name and contact must be added only 2 times. for ex.
Contact Card-1
Name-A
Name-B
Contact-1
Contact-2
Whenever I click on the button my name and contact get added in the list but with certain condition.
My code is
<md-list-item ng-show="showContactList" class="md-2-line" ng-repeat="numbers in contactList track by $index" >
<i ng-show="numbers.type == 'test'" class="material-icons md-avatar-icon">textsms</i>
<i ng-show="numbers.type == 'CELL' || numbers.type == 'EXT'" class="material-icons md-avatar-icon">phone</i>
<div class="md-list-item-text" ng-class="{'md-offset': phone.options.offset }">
<h3> {{ numbers.type }} </h3>
<p> {{ numbers.value }} </p>
</div>
<i class="material-icons md-avatar-icon add-rm-icon margin-right" ng-click="arrayText.push(numbers);">add</i>
</md-list-item>
You can use:
<div ng-repeat="item in items | filter:{visible: true} | limitTo: 50">
<p>{{item.id}}</p>
</div>
{visible- true} will return a list of all visible items
You can take a look at the angularjs docu for more information on the filter filter. http://docs.angularjs.org/api/ng.filter:filter
I need to remove an ionic 2 card when someone clicks on the trash icon. The code I have so far gives a querySelector is null error when I run it.
The view html looks like this:
<ion-card *ngFor="#mediaItem of mediaItems" id="item{{mediaItem.id}}" class="media-item">
<ion-card-header class="title-header">
<div class="title-item">
{{mediaItem.title}}
</div>
<ion-icon name="trash" class="bookmark_trash_icon" (click)="removeItem(mediaItem.id)"></ion-icon>
</ion-card-header>
<ion-card-content class="outer-content" >
<img src='{{mediaItem.url}}'>
</ion-card-content>
<ion-item class="bookmark-media-item">
<!-- <button (click)="topup(mediaItem)" clear item-left> -->
<div style="float:left;">
<ion-icon name="heart"></ion-icon>
{{mediaItem.liked}}
<ion-icon name="close-circle"></ion-icon>
{{mediaItem.disliked}}
</div>
<a (click)="showUserProfile(mediaItem.owner, mediaItem.username)" style="float:left;">
{{mediaItem.username}}
</a>
<div style="float:right;">
<img src="img/tiny-v.png" class="bookmark-v-icon">
{{mediaItem.credits_left}}
</div>
</ion-item>
</ion-card>
My controller javascript code looks like this:
removeItem(theItemID) {
let cardToHide = '#item'+theItemID;
document.querySelector(cardToHide).style.display = 'none';
}
The error I get is
querySelector is null
You can send the object instead of the id by changing that part of the code:
(click)="removeItem(mediaItem)"
And then find that object in you mediaItems array and delete it from there. Then your view will be automatically updated.
First get the index of that object in the array, and then you can use the mediaItems.splice(index, 1) to delete it from the array:
removeItem(theItem) {
let index = this.mediaItems.indexOf(theItem);
this.mediaItems.splice(index,1);
}
I have a listing of articles here, and I can't figure out how to execute the ng-click function calls on every new article inside the ng-repeat. Right now it works for existing articles, but when new articles are added dynamically (via AJAX), I need those to have the same functionality too.
For example: the ng-click function calls on the "+" sign to reveal social buttons seem to not work once new articles are inserted via AJAX (ie: delete articles, and let list be populated again with new elements)
Does AngularJS provide any tools to do that?
<div>
<div>
<input type="text" ng-model="search">
<span>{{filtered.length}} article(s)</span>
</div>
<div article-listing ng-repeat="article in filtered = (wikiArticles | filter:search)">
<!--Individual article begin-->
<span>
{{article.title}}
</span>
<div>
<a ng-click="articles.removeArticle($index)" title="Delete">
<span>✖</span>
</a>
<a ng-click="articles.toggleShare(article)">
<span class="plus-sign" title="Share">✖</span>
<div social-share ng-show="article.socialShare">
<div ng-click="socialShare = !socialShare" class="addthis_toolbox addthis_default_style addthis_32x32_style"
addthis:title="{{article.title}}" addthis:description="{{article.extract}}" addthis:url="{{article.url}}">
<a class="addthis_button_facebook"></a>
<a class="addthis_button_twitter"></a>
<a class="addthis_button_google_plusone_share"></a>
<a class="addthis_button_reddit"></a>
<a class="addthis_button_hackernews"></a>
</div>
</div>
</a>
</div>
<div>{{article.extract}}</div>
<!--Individual article end-->
</div>
</div>
Code for ng-click calls that don't seem to work for new article insertions
$scope.articles = (function() {
return {
shuffleArticles : function() {
$scope.wikiArticles.reverse();
},
removeArticle : function(index) {
$scope.wikiArticles.splice(index, 1);
$scope.fireAPICalls();
},
toggleShare : function(currArticle) {
var previousState = currArticle.socialShare;
angular.forEach($scope.wikiArticles, function(article) {
article.socialShare = false;
});
currArticle.socialShare = previousState ? false : true;
}
}
})();
Your ng-click calls are actually working- you can watch the ng-show toggle in the debugger.
The problem is that there is nothing to display on the new items you add.
The articles you initially add all have their icons populated with the .addthis classes, for instance here's your Facebook icon element:
<a class="addthis_button_facebook at300b" title="Facebook" href="#">
<span class=" at300bs at15nc at15t_facebook">
<span class="at_a11y">Share on facebook</span>
</span>
</a>
at300bs includes the following css which displays the image:
background: url(widget058_32x32.gif) no-repeat left!important;
However as you add new items, you aren't including the needed .addthis classes to them. Their elements look like this:
<a class="addthis_button_facebook"></a>
So ng-show has nothing to display (it shows a 0x0 div).
Add the .addthis classes to your new elements as you add them and you'll be all set.
