String interpolation with angular not binding - javascript

I'm trying to bind the data to a template using string interpolation. When I am trying to refer the variable in the template, then it returns the following error:
core.js:1350 ERROR TypeError: Cannot read property 'status' of
undefined.
HTML code:
<div class="chat-main">
<div class="col-md-12 chat-header rounded-top bg-primary text-white hide-chat-box">

<span class="text-muted"> {{task.eventType}}</span>
</div>
</li>
</ul>
</div>

task is local variable scope only inside ngFor template that mean ul element here
just move this span element to be inside `ngFor' template

In your App\Http\ProductsController.php or whichever file you use in fetching products from the database, you should see a function paginate(12), change it to paginate(60)
The title of your post is a little confusing as it doesn't match your description, I'll do my best to help though!
Undefined Variable: $products
This will most likely be due to the controller not passing a variable to the blade template.
In your controller, make sure that you are passing the variables to the view like so:
public function index() {
// Your logic here
return view('my-index', [
'products' => $products
]);
}
Pagination Limits
Displaying 12 items rather than 60 will be due to the limits passed to the paginate() function within the controller. Make sure you have set this to 60
public function index() {
// Retrieve up to 60 products at a time
$products = Product::paginate(60);
return view('my-index', [
'products' => $products
]);
}
Forelse loops
You may want to consider using a #forelse loop rather than a #foreach loop in case you don't have any products being returned from the query
#forelse($products as $product)
// Display your products
#empty
// Display a message saying no products were found
#endforelse

please help me to get the value of "s" with out using the ng-click, so that i can send the value of "s" to the controller A for the save function.
Just a suggestion, Can't we create a variable named "selectedTab" and when you click the tab just generate a KeyUp event from that tab and in this event you can change the value this variable and while posting just get the value from that "selectedTab" variable.

Generating Dynamic Template Reference Variables in Angular 6

We have a customised component from MDB (http://mdbootstrap.com), which requires the definition of template reference variables.
We are creating a listing that utilises a Card Component (https://mdbootstrap.com/angular/components/flipping-cards/). We define the basic template for one card, and then use *ngFor to loop through the data and create a card of the same template for each entry in our data.
The card component uses the following structure:
<mdb-card-rotating #cards>
<!-- Card's structure comes in here -->
<!--Triggering button-->
<a class="rotate-btn" data-card="card-1" (click)="cards.toggle()">
</mdb-card-rotating>
This component uses the template reference variable #cards to run the function toggle(), which rotates the card to display additional content.
However, this reference variable needs to be unique for each card; in our current set-up, the *ngFor loop ends up creating the same reference variable #card for all our generated cards, and then, when the triggering button is pressed from any of the cards, all cards end up rotating instead of just that specific card.
Here's the entire structure:
<div class="mb-5 pb-4 col-sm-12 col-xs-12 col-md-12 col-lg-4" *ngFor="let el of fetchedResults; let i = index">
<div class="col-md-12">
<mdb-card-rotating #cards>
<!--Front Side-->

<h4>{{ el.first_name }} {{ el.last_name }}</h4>
<p>{{ el.profession }}</p>
<!--Triggering button-->

</div>
</div>
<!--/.Front Side-->
<!--Back Side-->
<div class="back tp-box_side tp-box_back">

Bootstrap Model is closed everytime after click on the cancel icon in AngularJS?

I have to remove the product from the list. My product is removed properly but after I click on the cancel icon, the model closes. I am using AngularJS.
/**

$scope.albumKey = [];
$scope.albumObject = [];
$scope.setAlbumObject = [];
$scope.removeSelectedProductFromAlbum = function(event, index, productObject) {
//GET THE ALBUM OBJECT FROM THE SCOPE
$scope.setAlbumObject = $scope.setAlbumObject;
//PROCESS TO REMOVE productKeyId IN ALBUM.
var productKeyId = productObject.keyId;
if(productKeyId != undefined) {
if($scope.productsKeyIdList != undefined && $scope.productsKeyIdList != null) {
var index = $scope.productsKeyIdList.indexOf(productKeyId);
$scope.productsKeyIdList.splice(index, 1);
updatedProductKeyArray = $scope.productsKeyIdList;
//Calling updateArray inner function for update sharedBuyerKeyIdList after remove the keyId
updateArray();
}
}
}
//CALLING THE updateArray FUNCTION FOR UPDATE THE PRODUCT AFTER DELETING THE DATA
function updateArray () {
var PRODUCT_DB_REF = firebase.database().ref('datastore/productsAlbum');

Change background color ng-click

I am new to angular, and I have a codepen that I am working in. I want to change the background color of another div to the corresponding color of the button when the user clicks the nav buttons at the bottom. I am not sure of the best way to implement this. Here is the code I have below.
Link to the codepen editor http://codepen.io/modDesigns/pen/YyKwGj
HTML
<div class="wrapper" ng-app="mobile">
<div class="phone">
<div class="page" ng-controller="Screen">
<div class="top_background" ng-style="{'background-color': changeScreen()}">
<i class="fa fa-signal sigs"></i>
<i class="fa fa-wifi sigs"></i>
<i class="fa fa-battery-full bats"></i>
<span class="times">11:44am</span>
<div class="home">
<h5 class="text-center"><i class="fa fa-user"></i> Account</h5>
</div>
<div class="navigation">
<div class="col-sm-3 homes" ng-style="{'background-color': '#C0392B'}" ng-click="changeScreen('#C0392B')">
<h4><i class="fa fa-home"></i></h4>
</div>
<div class="col-sm-3 shop" ng-click="" ng-style="{'background-color': '#E74C3C'}">
<h4><i class="fa fa-shopping-cart"></i></h4>
</div>
<div class="col-sm-3 feeds" ng-click="" ng-style="{'background-color': '#E67E22'}">
<h4><i class="fa fa-comment"></i></h4>
</div>
<div class="col-sm-3 settings" ng-click="" ng-style="{'background-color': '#F39C12'}">
<h4><i class="fa fa-cog"></i></h4>
</div>
</div>
</div>
</div>
</div>
Javascript
var app = angular.module('mobile', []);
app.controller('Screen', function($scope) {
$scope.changeScreen = function(myClass) {
$scope.theClass = myClass;
return $scope.theClass;
};
});
You actually don't need to write a function to get this working (unless you want to do more than you specified). You can use ngClick to set a variable and also use that variable as your background color, all within the HTML.
http://codepen.io/anon/pen/JYPJBR
<div class="wrapper" ng-app="mobile">
<div class="phone">
<div class="page" ng-controller="Screen">
<div class="top_background" ng-style="{'background-color': screenColor}">
<i class="fa fa-signal sigs"></i>
<i class="fa fa-wifi sigs"></i>
<i class="fa fa-battery-full bats"></i>
<span class="times">11:44am</span>
<div class="home">
<h5 class="text-center"><i class="fa fa-user"></i> Account</h5>
</div>
<div class="navigation">
<div class="col-sm-3 homes" ng-style="{'background-color': '#C0392B'}" ng-click="screenColor='#C0392B'">
<h4><i class="fa fa-home"></i></h4>
</div>
<div class="col-sm-3 shop" ng-click="screenColor='#E74C3C'" ng-style="{'background-color': '#E74C3C'}">
<h4><i class="fa fa-shopping-cart"></i></h4>
</div>
<div class="col-sm-3 feeds" ng-click="screenColor='#E67E22'" ng-style="{'background-color': '#E67E22'}">
<h4><i class="fa fa-comment"></i></h4>
</div>
<div class="col-sm-3 settings" ng-click="screenColor='#F39C12'" ng-style="{'background-color': '#F39C12'}">
<h4><i class="fa fa-cog"></i></h4>
</div>
</div>
</div>
</div>
</div>
But, if you just want to know why your code isn't working, it's because you're trying to use changeScreen() as both a getter and a setter, but it's not set up to do that.
You could either reference the variable theClass like so:
<div class="top_background" ng-style="{'background-color': theClass}">
Or else modify the function to not set theClass to undefined when you run it without arguments:
$scope.changeScreen = function(myClass) {
if(angular.isDefined(myClass)){
$scope.theClass = myClass;
}
console.log('the class', $scope.theClass);
return $scope.theClass;
};
Here is a codepen with what you wanted:
http://codepen.io/anon/pen/rOBwZV
HTML only is changed:
<div class="wrapper" ng-app="mobile" ng-init="bgCol='#F39C12'">
<div class="phone">
<div class="page" ng-controller="Screen">
<div class="top_background" style="background-color: {{bgCol}}">
<i class="fa fa-signal sigs"></i>
<i class="fa fa-wifi sigs"></i>
<i class="fa fa-battery-full bats"></i>
<span class="times">11:44am</span>
<div class="home">
<h5 class="text-center"><i class="fa fa-user"></i> Account</h5>
</div>
<div class="navigation">
<div class="col-sm-3 homes" ng-style="{'background-color': '#C0392B'}" ng-click="bgCol='#C0392B'">
<h4><i class="fa fa-home"></i></h4>
</div>
<div class="col-sm-3 shop" ng-click="bgCol='#E74C3C'" ng-style="{'background-color': '#E74C3C'}">
<h4><i class="fa fa-shopping-cart"></i></h4>
</div>
<div class="col-sm-3 feeds" ng-click="bgCol='#E67E22'" ng-style="{'background-color': '#E67E22'}">
<h4><i class="fa fa-comment"></i></h4>
</div>
<div class="col-sm-3 settings" ng-click="bgCol='#F39C12'" ng-style="{'background-color': '#F39C12'}">
<h4><i class="fa fa-cog"></i></h4>
</div>
</div>
</div>
</div>
</div>
The issue in your code is very tiny. Check this example to see how it works.
The first issue is that you call the method in html via:
<div class="top_background" ng-style="{'background-color': changeScreen()}">
Pay attention - no parameter passed to method.
But in angularjs method is expecting a class name.
Second, it would be better to have the entire style in an object as per example I provided, because in case there will be some other style properties, they can be added there and not call another function inside ng-style.
Hope this helps.
