In my project I need to show for each element its image.
This is my html:
<div ng-repeat="event in events.events" class="event show-place" data-id="#{{ event.id }}"
ng-mouseenter="selectEvent(event)">
<div class="cover-events">
<img width="100%" height="100%"
ng-src="#{{ selectedEvent.place.image | addFullPathToImage }}"
alt="#{{ selectedEvent.place.name }}"
>
<div class="user-info">
<a href="#{{ event.created_by.profileSlug }}">
<immagine-profilo hashid="#{{ event.created_by.hashid }}"
username="#{{ event.created_by.profile.username }}"
photo="#{{ event.created_by.profile.photo }}"></immagine-profilo>
<div class="user-event" ng-bind="event.created_by.profile.username"></div>
<rating class="user-experience" stars="#{{ event.created_by.level }}"
icon="star"></rating>
</a>
</div>
</div>
<div class="info-event">
<div vertilize class="content-info">
<div class="title-place">
<h2 ng-bind="event.place.name"></h2>
</div>
<div class="date-time">
#{{ event.unix_date | formatDate }} | #{{ event.time_start }}
</div>
<div class="event-feature">
<div class="category pull-left">
<img ng-src="#{{ event.category.icon | addFullPathToIcon }}"
alt="#{{ event.category.name }}">
<span ng-bind="event.category.name"></span>
</div>
<div class="difficulty pull-left">
<rating class="difficulty-bar" stars="#{{ event.difficulty_level }}"
icon="circle"></rating>
<span>
{{ trans('frontend/events/events.strings.difficulty') }}
</span>
</div>
<div class="participants pull-left">
<div class="speech-bubble speech-bubble-bottom">
#{{ event.participants_count }}
</div>
<span>{{ trans('frontend/events/events.strings.participants') }}</span>
</div>
</div>
</div>
<a class="link-with-arrow"
href="{{ localeRoute('events.event', [null, null])}}/#{{ event.slug }}/#{{ event.id }}">
{{ trans('frontend/pages/place.sidebar.links.read_more') }}
</a>
</div>
the image code is this:
<img width="100%" height="100%"
ng-src="#{{ selectedEvent.place.image | addFullPathToImage }}"
alt="#{{ selectedEvent.place.name }}">
and this is the filter:
app.filter('addFullPathToIcon', function () {
return function (text) {
return window.paths.categoriesPath + "/" + text;
}
});
When I run the code, the same image is shown for each event, if I click on one of it, the images will change and show the second image for every event.
Someone can help me to see the error?
It looks to me like there's only one "selectedEvent", and it is defined on ng-mouseenter. Perhaps you want
<img width="100%" height="100%"
ng-src="#{{ event.place.image | addFullPathToImage }}"
alt="#{{ event.place.name }}">
instead inside your ng-repeat if you don't want all the images to change with the event that is selected...

I have looked at almost every solution I could find about this but I can't get my code to work. I wan't to put a banner after 3 ng-repeats
<div class="row products-row" ng-init="onInit()">
<div class="col col-34 fashion-product-container" ng-repeat="product in results = fashionProducts | FashionFilter:params | orderBy:sortby_obj.propertyName:sortby_obj.reverse as fashionResults">
<div class="list card">
<div class="item item-image product-image-wrapper">
<pre-img ratio="_3_4">
<img class="product-image" ng-src="{{ product.image }}" spinner-on-load>
</pre-img>
</div>
<div class="item item-body product-description-wrapper">
<h5 class="product-title">
{{ product.name }}
</h5>
<p class="product-description">
<b class="actual-price bold-price">${{product.price_sale}}</b>
<span class="previous-price bold-price" ng-show="product.price != '0'">${{product.price}}</span>
</p>
</div>
</div>
</div>
<div class="col-md-12" id="Banner" ng-if="$index==3">Banner</div>
</div>
use $index
like
<div id="banner" ng-show="$index == 3"></div>
Now this will show banner div when its the third element of ng-repeat.
Your <div class="col-md-12" id="Banner" ng-if="$index==3">Banner</div> is outside of <div> containing ng-repeat tag. due to that $index is undefined.
Just put it inside the div of ng-repeat and it will work.
Try this:-
<div class="row products-row" ng-init="onInit()">
<div ng-repeat="product in results = fashionProducts | FashionFilter:params | orderBy:sortby_obj.propertyName:sortby_obj.reverse as fashionResults">
<div class="col col-34 fashion-product-container">
<div class="list card">
<div class="item item-image product-image-wrapper">
<pre-img ratio="_3_4">
<img class="product-image" ng-src="{{ product.image }}" spinner-on-load>
</pre-img>
</div>
<div class="item item-body product-description-wrapper">
<h5 class="product-title">
{{ product.name }}
</h5>
<p class="product-description">
<b class="actual-price bold-price">${{product.price_sale}}</b>
<span class="previous-price bold-price" ng-show="product.price != '0'">${{product.price}}</span>
</p>
</div>
</div>
</div>
<div class="col-md-12" id="Banner" ng-show="$index==3">Banner</div>
</div>
</div>
I have this code:
<main class="gallery">
<nav class="gallery-list-thumbs">
<ul>
<li ng-click="showLarge($event); modalShow()" ng-repeat="photo in photos | filter:{'section': section }">
<img data-ref="ref-{{ photo.id }}" data-orientation="{{ photo.orientation }}" class="photo-small" ng-src="photos/{{ photo.section }}/th/{{ photo.src }}">
</li>
</ul>
</nav>
<section class="gallery-item" ng-hide="modalHidden">
<h1 ng-model="section">{{ section }}</h1>
<div class="photo-container">
<div class="modal-close" ng-click="modalShow()"></div>
<div class="modal-prev"></div>
<div class="modal-next"></div>
<img data-photoref="ref-{{ photo.id }}" ng-repeat="photo in photos | filter:{'section': section }" class="photo-large below orientation-{{ photo.orientation }}" ng-class="{'above':$first}" ng-src="photos/{{ section }}/{{ photo.src }}">
</div>
</section>
</main>
What I hope to achieve, is to hide the modal-prev when the user click on the first li in gallery-list-thumbs and the same thing with modal-next on the last li.
So far, using $index, it's fairly easy since I can target it by a scope change, but how do I get the last element when there's a different amount of images per galleries? It would be easier if the next and prev arrows were inside the ng-repeat since I could use $first and $last, but I don't want to have to include them in.
OK, I was able to find it by myself.
The solution was to change a scope on $first and last and then add a ng-show and ng-hide depending on the scope value.
Here's the code if anyone has this kind of issue:
<main class="gallery">
<nav class="gallery-list-thumbs">
<ul>
<li ng-click="showLarge($event); modalShow();setPosition('inbetween'); $first && setPosition('first') ; $last && setPosition('last')" ng-repeat="photo in photos | filter:{'section': section }">
<img data-ref="ref-{{ photo.id }}" data-orientation="{{ photo.orientation }}" class="photo-small" ng-src="photos/{{ photo.section }}/th/{{ photo.src }}">
</li>
</ul>
</nav>
<section class="gallery-item" ng-hide="modalHidden">
<h1 ng-model="section">{{ section }}</h1>
<div class="photo-container">
<div class="modal-close" ng-click="modalShow()"></div>
<div class="modal-prev" ng-hide="currentOrder == 'first';">{{ currentOrder }}</div>
<div class="modal-next" ng-hide="currentOrder == 'last';">{{ currentOrder }}</div>
<img data-photoref="ref-{{ photo.id }}" ng-repeat="photo in photos | filter:{'section': section }" class="photo-large below orientation-{{ photo.orientation }}" ng-class="{'above':$first}" ng-src="photos/{{ section }}/{{ photo.src }}">
</div>
</section>
</main>
I am using angularJS + cordova for a mobile application. I am able to display a list view, In that I am trying to update a list item when I click on that item, the values are changing but the UI is not updating.
Here is my code.
<md-list post class="" role="list" >
<md-item class="card" ng-repeat="post in posts">
<div class="card-header">
<div class="pro-pic">
<img src="{{post.UserImage}}" />
</div>
<h2>{{ post.UserName }}
<span>{{ post.CreatedDate | date:'medium' }} via --</span>
</h2>
<div class="post-info">{{ post.Description }}</div>
</div>
<div class="card-body">
<div class="card-img" ng-hide="post.IdeaImagePost == 0">
<img src="{{ post.IdeaImagePost }}" />
</div>
</div>
<div class="card-footer">
<div id="likeID" ng-click="onLike(post)"><i class="fa fa-thumbs-up {{post.LikeUserStatus ? 'active' : ''}}"></i><label> Like</label><span class="badge badge-xs badge-pink">{{ post.LikeUsersCount }}</span></div>
<div><i class="fa fa-commenting"></i> Comment<span class="badge badge-xs badge-pink">{{ post.CommentsCount }}</span></div>
</div>
</md-item>
</md-list>

Here is JS code
$scope.onLike = function(post) {
console.log("LikeUserStatus: " + post.LikeUserStatus);
post.LikeUserStatus = !post.LikeUserStatus;
post.LikeUsersCount = post.LikeUserStatus ? parseInt(post.LikeUsersCount)+1 : parseInt(post.LikeUsersCount)-1;
console.log("LikeUserStatus: " + post.LikeUserStatus);
};
console.log("LikeUserStatus: " + post.LikeUserStatus);
` $timeout(function(){
post.LikeUserStatus = !post.LikeUserStatus;
post.LikeUsersCount = post.LikeUserStatus ? parseInt(post.LikeUsersCount)+1 :parseInt(post.LikeUsersCount)-1
})`;
$timeout runs the digest cycle after execution
I'm trying to use ngFor under a template and retrieve children to modify them later.
Here is my template:
<div (mouseenter)="showTooltip()" (mouseleave)="hideTooltip()" (mousedown)='onMouseDown($event)' class='slider slider-{{ orientation }}'>
<div class='slider-track'>
<div #trackLow class='slider-track-low' [ngClass]="{hide: (type === 'slider' || selection === 'none' || selection === 'after')}"></div>
<div #trackSelection class='slider-selection' [ngClass]="{hide: (selection === 'none')}"></div>
<div #trackHigh class='slider-track-high' [ngClass]="{hide: (selection === 'none' || selection === 'before')}"></div>
</div>
<div class="slider-tick-label-container" [ngClass]="{hide: labels.length === 0}">
<div #labelElements *ngFor="let label of ticksLabels" class="slider-tick-label">{{ label }}</div>
</div>
<div class="slider-tick-container" [ngClass]="{hide: ticks.length === 0}">
<div #tickElements *ngFor="let tick of ticks" class="slider-tick {{ handleType }}"> </div>
</div>
<div #tooltipMain class="tooltip tooltip-main {{ tooltipPosition }}" role="presentation">
<div class="tooltip-arrow"></div>
<div #tooltipMainInner class="tooltip-inner">Current value: {{ value }}</div>
</div>
<div #tooltipMin class="tooltip tooltip-min {{ tooltipPosition }}" role="presentation">
<div class="tooltip-arrow"></div>
<div #tooltipMinInner class="tooltip-inner"></div>
</div>
<div #tooltipMax class="tooltip tooltip-max {{ tooltipPosition }}" role="presentation">
<div class="tooltip-arrow"></div>
<div #tooltipMaxInner class="tooltip-inner"></div>
</div>
<div #minHandle tabindex="0" (keydown)="keydown(0, $event)" (focus)="showTooltip()" (blur)="hideTooltip()" class='slider-handle min-slider-handle {{ handleType }}' role='slider'></div>
<div #maxHandle tabindex="0" (keydown)="keydown(1, $event)" (focus)="showTooltip()" (blur)="hideTooltip()" class='slider-handle max-slider-handle {{ handleType }}' [ngClass]="{hide: type === 'slider'}" role='slider'></div>
</div>
Both ngFor are rended like this in DOM:
<div class="slider-tick-container">
<!--template bindings={}-->
</div>
In my component I try to retrieve elements with:
#ViewChildren('tickElements') private tickElements: QueryList<ElementRef>;
#ViewChildren('labelElements') private labelElements: QueryList<ElementRef>;
Both are undefined because of the rendering problem...
I try to remove the template and replace it by <div *ngFor="let i of [1,2,3,4]">{{i}}</div> and same problem !
The full code is available here: https://github.com/jaumard/ng2-bootstrap/blob/ticksLabels/components/slider/slider.component.ts#L15
This is what I have so far:
<div ng-repeat="storeSection in main.foodBySection" ng-show="main.sortBy === 'storeSection'">
<h4>{{ storeSection.category }}</h4>
<div ng-repeat="ingredient in main.ingredients | orderBy: 'name'"
ng-if="ingredient.storeSection === {{ storeSection.category }}">
<p><input type="checkbox" ng-model="ingredient.added"/> {{ ingredient.name }} <span
class="ingredient-source">- {{ ingredient.source }}</span></p>
</div>
</div>
Basically, I only want to display the items in main.ingredients that have the same category as the header, but I cannot access {{ storeSection.category }} once I use a new ng-repeat. Any ideas?
<div ng-repeat="storeSection in main.foodBySection" ng-show="main.sortBy === 'storeSection'">
<h4>{{ storeSection.category }}</h4>
<div ng-repeat="ingredient in main.ingredients | orderBy: 'name'"
ng-if="ingredient.storeSection === storeSection.category">
<p><input type="checkbox" ng-model="ingredient.added"/> {{ ingredient.name }} <span
class="ingredient-source">- {{ ingredient.source }}</span></p>
</div>
</div>
<div ng-repeat="storeSection in main.foodBySection" ng-show="main.sortBy === 'storeSection'">
<h4>{{ storeSection.category }}</h4>
<div ng-repeat="ingredient in main.ingredients | orderBy: 'name'"
ng-if="ingredient.storeSection === storeSection.category ">
<p><input type="checkbox" ng-model="ingredient.added"/> {{ ingredient.name }} <span
class="ingredient-source">- {{ ingredient.source }}</span></p>
</div>
</div>
Don't interpolate storeSection.category, ng-if works with angular-expressions just like the left-hand operandingredient.storeSection is getting evaluated by it
As pointed out in another answers, the cause of the problem is that you're using interpolation in your ngIf directive, which one works with angular-expressions.
Tips:
Use preferably ngIf instead of ngShow(in your first <div>).
I also recommend you to use the native filter instead of this check using ngIf(in ngRepeat) and to use the ngRepeat#special-repeats.
So you can have something like this:
<div ng-repeat-start="storeSection in main.foodBySection" ng-if="main.sortBy === 'storeSection'">
<h4 ng-bind="storeSection.category"></h4>
</div>
<div ng-repeat-end ng-repeat="ingredient in main.ingredients | filter: { storeSection: storeSection.category } | orderBy: 'name'">
<p>
<input type="checkbox" ng-model="ingredient.added" /> {{ ingredient.name }} <span class="ingredient-source">- {{ ingredient.source }}</span></p>
</div>
