I'm working on a Store application and I need to show 2 different strings based on a response.
If I receive the response with no item title I need to show "No Item Title Found", else, I need to show item's title limited to a certain amount of characters.
Here is my code:
<div ng-switch on="item.title">
<div ng-switch-when="!item.title.length">
<p class="prod-title cursor-pointer"
ng-click="searchCtrl.openItemTab(item,event)">
{{ item.title = 'Title Not Found'}}</p>
</div>
<div ng-switch-default>
<p class="prod-title cursor-pointer"
ng-click="searchCtrl.openItemTab(item,event)">
{{ item.title | limitTo:60 }}</p>
</div>
</div>
I'm able to see Items titles when their length is greater than 0, but, I'm not able to see "No Item Title Found" when length is equal to 0.
Any suggestion? Thanks in advance.
use ng-if directive to show 'Title not found' when you don't have an available title.
<p ng-if='!item.title' class="prod-title cursor-pointer" ng-click="searchCtrl.openItemTab(item,event)">
Title Not Found
</p>
<p ng-if='item.title' class="prod-title cursor-pointer" ng-click="searchCtrl.openItemTab(item,event)">
{{item.title}}
</p>
Make the ng-switch like:
<div ng-switch on="item.title.length">
<div ng-switch-when="0">
Currently what you have means
if item.title (expression) equals true (!item.title.length == item.title) enter the first block
in any other case enter the second.

I want to generate a span element for each saved tag from my collection tag's array.
I use firebase and get in *ngFor loop i get one big span element with all saved tags separated by comma, instead of getting a span for each tag. Is there any way that i can't prevent this from happening. Also i have created an interface for Saved.
Thanks in advance.
<div class="card">
<div class="card-body">
<h5 class="card-title text-center">{{saved?.title}}</h5>
<hr />
<div *ngFor="let tag of saved.tags">
<span class="badge badge-pill badge-primary">{{saved?.tags}}</span>
</div>
<hr /> View
</div>
</div>
//Saved interface in Saved.ts file
export interface Saved {
id: string;
title: string;
tags: string[];
}
Try having your code like this. This should make the span element repeat rather than the div and then make sure to reference the individual tag rather than the array inside.
If the tag has a name / title attribute swap {{ tag }} for {{ tag.title}}
looking at the interface its just {{ tag }}.
<div>
<span *ngFor="let tag of saved.tags" class="badge badge-pill badge-primary">
{{tag}}
</span>
</div>
Reference to Angular docs on using *ngFor to display data.
At the moment, you are referencing the array inside your *ngFor. So, as a result, you should see the whole list of n tags, for n times. If you switch from {{saved?.tags}} to {{tag}}. You will see one div per tag including one span and a single tag inside.
So for getting one span per tag, use it like the following:
<div class="card">
<div class="card-body">
<h5 class="card-title text-center">{{saved?.title}}</h5>
<hr />
<div>
<span class="badge badge-pill badge-primary" *ngFor="let tag of saved.tags">
{{tag}}
</span>
</div>
<hr />
View

I have an array of comments. For each of the comment, I have a hidden form where you can reply. That item in each object of the array is called: comment.showSubCommentForm. When I click on Reply, I want to be able to reply with a comment and the function called: commentOnSubPost.
I load my data in chunks of 10 (lazy loading) which I am doing by using the infinite-scroll-distance Angular module. Every time I reach the end of the page, I get the next 10 items and add them to the $scope.comments array, which you can see below is what I am running my ng-repeat on .
The problem is that, although the commentOnSubPost works really well as in it adds the reply to the comment, I have reload the data so I can get the updated $scope.comments with the new reply. BUT - as I have implemented lazy loading, how do I do that if say I am on the 20th page?
I looked at some similar posts but their approach from mine was very different so am very lost.
My HTML:
<div infinite-scroll='loadMore()' infinite-scroll-distance='1'>
<div class="row">
<div ng-repeat="comment in comments track by $index">
<ul class="comments">
<li class="clearfix">
<a ng-href="#">SomeLink</a>
<div>
<p >{{ comment.date }} <a ng-href="/wall#/profile/main/{{ comment.userID }}">{{ comment.fullname }}</a> says <i class="commentReply"><a href ng-click="comment.showSubCommentForm = !comment.showSubCommentForm"><small>Reply</small></a></i></p>
<p class="mainComment">
{{ comment.comment }}
<p class="meta"><i class="showReply"><a href ng-click="comment.showReplies = !comment.showReplies"><small>Show Replies</small></a></i></p>
</p>
</div>
<div ng-show="comment.showSubCommentForm">
<form ng-submit="commentOnSubPost( post._id, comment._id, subComment)">
<div class="form-group">
<div class="form-group">
<textarea ng-model="subComment" class="form-control" placeholder="Reply to the above comment"></textarea>
</div>
<input type="submit" value="Reply">
</div>
</form>
<div ng-show="comment.showReplies" ng-repeat="subComment in comment.subComments track by $index">
<ul class="comments">
<li class="clearfix">
<a ng-href="/wall#/profile/main/{{ comment.userID }}"><img ng-src="{{ subComment.profilePic }}" class="avatar" style="border-radius: 50%"></a>
<div class="post-subComments">
<p class="meta">{{ subComment.date }}<a ng-href="SomeLink"> {{ subComment.fullname }}</a></p>
<p>
{{ subComment.comment }}
</p>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</div>
I won't add too much information here as I don't want to overload this post but if you need any particular information, please do let me know. I just need to know how do I reload the data (or not if there's another approach) so that I can get the latest data.
I hope this makes sense.
Thanks in advance!
Like you have $scope.comments = []; then on each call you just have to append upcoming data to this array.
Like $scope.comments = $scope.comments.concat(response.data);
In this way lazy loading will work.
I fixed this with making a Node route which gives back the exact comment I have just added. Then, I found that commentID in my $scope.comments and made it's subCommenemts to the one I have locally.
It does the job and the data is real. One drawback is that if at that time, there's another comment, it won't show up until the page's refreshed but I'm not too fussed about that.
I have the following in a view file:
<p class="presentation black">Sections:
<span data-ng-if="currentTab == 'tab1'">
<div ng-repeat="question in filtered = (template.questions | unique:'sectionName')"></div>
<p class="presentation black">{{filtered.length}}</p>
</span>
<span data-ng-if="currentTab == 'tab2'">
<div ng-repeat="sheet in filtered = (template.sections[0].sheets | unique:'name')"></div>
<p class="presentation black">{{filtered.length}}</p>
</span>
</p>
When tab1 is selected, the information is displayed correctly. However when on tab2, it appears that <p> element in both spans is being displayed - an empty value in displayed for the <p> element related to tab1. By looking at the DOM tree it also seems that when on tab2, the ng-if condition is not displaying: <!-- end ngIf: currentTab == 'tab2' -->. Can anyone see where the issue may be? Let me know if more code is required.
The "p" shouldn't be in a "span" according to HTML5 specs. Change the "span" to a "div".

I've a situation where I want to display an error message on the page when my modal don't have any records to show. This could be on the initial load or after applying some filter criteria on the page.
I'm using ng-if to check the count of records on the result set after applying the filter, that is why when my page initially loads as there is no data in the filtered result rest it is showing up the error message first and then later it is showing the data.
Any insight would be highly appreciated
prod.skulist is my modal.
<ul class="prd-list">
<li ng-repeat=" p in filtered =(prod.skulist | categoryFilter:prod.selectedFormat :prod.selectedRating) | filter :priceRange" id=" {{p.sku}}">
<figure class="prd-img" ng-click="wrapCtrl.showProdDetils(p.sku,prod.catName)">
<div style="background-image: url({{wrapCtrl.imageLocation+p.image}}); background-repeat: no-repeat;"></div>
<figcaption class="prd-nam f8">{{p.title}}</figcaption>
<span class="new-item" ng-show="{{p.isnew}}"><img src="Content/images/new.png" /></span>
<span class="new-item" ng-show="wrapCtrl.compareStreetDate(p.streetdate)"><img src="/Content/images/coming-soon.png" /></span>
</figure>
<div class="prd-price f5">
{{p.currentprice | currency}}<span class="sales" ng-show="{{p.onsale}}">ON SALE</span>
<span class="cart-btn" ng-click="wrapCtrl.addCart($event)"></span>
<div class="inactive-cart-btn" ng-show="wrapCtrl.compareStreetDate(p.streetdate)"></div>
</div>
</li>
</ul>
<div ng-if="(filtered | filter :priceRange).length ==0" class="error-box">
<div class=" wrp"><span class="error-head">I hate when this happens</span></div>
<div class="wrp error-message">
<span class="f9 pad-top">It looks like I don't have exactly what you are looking for.</span>
<span class="f9 pad-bot">try adjusting your filters to see more</span>
</div>
</div>
I ran into a similar situation and found an ugly, though working solution by using the $timeout service. In your case you would have a scope variable, lets call it loadTimeGiven = false and after the $timeout you set it to true. Then simply do
ng-if="(filtered | filter :priceRange).length ==0 && loadTimeGiven"
Alternatively you could set loadTimeGiven based on a service that your modal has access to.

having a list of items ng-repeat on the left, then selecting the main content (on the right) from the options, then displaying the full content as the main selection.
ng-if ? ng-show ?
not sure how well I've described this but it should be pretty obvious from the fiddle.
thanks in advance.
I modified your plnkr http://plnkr.co/edit/9qZsp2o22L5x1a0JofPy?p=preview
I create a currectIssue variable for your right content display.
In left content, Read More.. has been change to <a ng-click="showIssue(x)">Read More..</a>
updated plunk: http://plnkr.co/edit/hGsdkybRMoRct8VykCcB?p=preview
well, you might consider:
- use another scope variable to display the selected item from the object
- I'd use ng-if in this case as that will create/destroy the content as needed
// controller
$scope.selectIssue = function(x) {
$scope.issue = x;
}
$scope.selectIssue($scope.issues['1']);
//view
<article>
<h3 >{{issue.title}}</h3>
<p>{{issue.priority}}</p>
<p class="lead">{{issue.author}} - 6/12/2014</p>
<div ng-if="issue.author == 'Andy'">
<hr>
<p>{{issue.message}}</p>
