Retreiving filteredItems from uib-typeahead custom popup doesn't work

Retreiving filteredItems from ng-repeat in controller through $scope doesn't work
I am trying to get filtered items from ng-repeat but I get undefined when console logging the value of $scope.filteredItems. I even tried the solution provided in Can't get the filtered items from my filtered list inside a modal but it didn't work either.
The ng-repeat is in a uib-typeahead custom popup templates for typeahead's dropdown. I am trying to get the filtered value in the parent controller.
example-input.component.ts
/////////////////////////////////
componentController.$inject = ['$scope', 'exampleDataService'];
function componentController($scope, exampleDataService) {
var someInput = this;
someInput.typedText = '';
someInput.onKeyPress = onKeyPress;
return;
/////////////////////////////////
//controller implementation detail
/////////////////////////////////
function onKeyPress(){
console.log($scope.filteredItems); // prints undefined
}
}
UIB-Typeahead Custom Template for Popup
<script type="text/ng-template" id="input-custom-template.html">
<ul class='dropdown-menu' ng-show='isOpen() && !moveInProgress'
ng-style="{top: position().top+'px', left: position().left+'px'}"
role='listbox' aria-hidden='{{!isOpen()}}' match-limit in-view-container>
<li style="max-height:0;overflow:hidden"><span in-view="$inview && matchLimit.reset()"> </span></li>
<li ng-repeat='match in (filteredItems = (matches | someMatchSort:query | limitTo:matchLimit.value)) track by some.model.example '
ng-class='{active: isActive($index) }'
ng-mouseenter='selectActive($index)'
ng-click='selectMatch($index, $event)'
role='option' id='{{::match.id}}'
in-view="!$inview && isActive($index) && scrollTarget.scrollIntoView()"
scroll-target
>
<div uib-typeahead-match index='$index' match='match'
query='query' template-url='templateUrl'>
</div>
</li>
</ul>
</script>
<input type="text" ng-model="someInput.typedText" typeahead-min-length="1"
uib-typeahead="option.example as option.value for option in someInput.options | filter:{value:$viewValue}"
class="form-control input-text-example icon-search"
placeholder="example"
typeahead-popup-template-url="input-custom-template.html"
ng-keypress="someInput.onKeyPress()"/>
If you need any additional info pls let me know. There is also a filter called someMatchSort.filter.ts but I'm not sure if it makes difference to add it here. Anyways let me know, I will update my question

You might want to use ng-keyup in your case.
Then in your component write like so
function onKeyPress(){
console.log($scope.$$childHead.matches.length);
}

ionic ngFor not working

I'm using Ionic Creator and when I export the project, it doesn't have any .ts file. I have issue trying to get ngFor working for my code.
I'm using the $scope variable to pass array object from the Controller to the Template.
grocery.html (/template)
<ion-list id="groceriesHistory-list4">
<ion-item class="item-icon-right" id="groceries-list-item13" ng-repeat="grocery in groceries">{{ grocery.date }}
<span class="item-note">Free 1.5L Drink Redeemed</span>
<i class="icon ion-android-bar"></i>
</ion-item>
groceryCtrl
firebase.database().ref("table").orderByChild("user").equalTo("userid").on("value", function(snapshot) {
var credit = 0;
var groceryHistory = [];
snapshot.forEach(function(childSnapshot) {
var childData = childSnapshot.val();
//console.log(childData);
if(childData.type == 1) {
if(childData.used == 1) {
groceryHistory.push(childData);
}
}
});
console.log(groceryHistory);
$scope.groceries = groceryHistory;
There is no data to display even though $scope.groceries contain at least an object.
Edit1: I edited my code for angularjs v1 but there is still no data to display.
Edit2: It is working but I have to click the sidemenu first before the data display itself.

ng-for does not exists in angularjs. You need to use ng-repeat:
<ion-list id="groceriesHistory-list4">
<ion-item class="item-icon-right" id="groceries-list-item13" ng-repeat="grocery in groceries">{{ grocery.date }}
<span class="item-note">Free 1.5L Drink Redeemed</span>
<i class="icon ion-android-bar"></i>
</ion-item>
Based on your update2, your scope changes is not in a angular digest cycle. Simply put your changes in a $timeout to make sure a digest cycle will run:
$timeout(function(){
$scope.groceries = groceryHistory;
})

Angular JS ng-repeat element does not update

I have to display a list of products and be able to click on them to get more informations about them.
My list of products is stored in a service named: "productsServices"
I got an html page who display all my products and an other who display details for 1 product. Each html page have their own controller.
When I update a product in my detail page, the changement is done in my productsServices but are not validated in my global product view.
(function ()
{
angular.module('app').service('productsServices', ['$http', '$q', ProductsServices])
that = this
that.products = /*arrayOfData*/;
that.getProducts = function () {
return that.products;
}
})();
(function ()
{
angular.module('app').controller('ProductsController', ['$http', '$q', 'productsServices', ProductsController])
that = this
that.products = productsServices.getProducts;
that.showDetail = function (item) {
$state.go('menu.product', { myParam: item });
}
})();
<!--Global HTML page-->
<ion-content id="content" class="has-header has-subheader" delegate-handle="myScroll">
<ion-list>
<ion-item ng-repeat="product in that.products() track by product.ProductId" href="#" ng-click="that.showDetail({{product}})">
<div class="innerProd">
<img id="productPicture" name="productPicture" ng-src='data:image/png;base64,{{product.ThumbnailPhoto}}'></div>
<div class= "innerProd">
<p>{{product.Name}}</p>
<p>{{product.Price}}$</p>
<ion-option-button class="button button-assertive"
ng-click="doDelete({{product}})">
Supprimer
</ion-option-button>
</div>
</ion-item>
</ion-list>
<ion-infinite-scroll ng-if="moreDataCanBeLoaded()" icon="ion-loading-c" on-infinite="loadMoreData()" distance="100%">
</ion-infinite-scroll>
</ion-content>
So when I check the product sended in the "that.showDetail" method, it's the old product who is sended even if the product have been updated in the services.
I'm not english so sorry for language mistakes in my sentence ^^'
Thank in advance for your help ^^'

Ok I've find the ansewer to my question, I've replace the parameter that I'm sending to my "that.showDetail" function. I'm no more sending the object directly, but the index of my item.
<ion-item ng-repeat="product in that.products() track by product.ProductId" href="#" ng-click="that.showDetail({{$index}})">
I guess that angular doesn't update injected in a ng-click call ^^'
Thank you for your time guys

binding to controller object in Angular

I'm new to angular, trying to bind an an element's content into the controller's Scope to be able to use it within another function:
here is the scenario am working around:
I want the content of the <span> element {{y.facetName}} in
<span ng-model="columnFacetname">{{y.facetName}}</span>
to be sent to the controller an be put in the object $scope.columnFacetname in the controller
Here is a snippet of what I'm working on:
<div ng-repeat="y in x.facetArr|limitTo: limit track by $index ">
<div class="list_items panel-body ">
<button class="ButtonforAccordion" ng-click="ListClicktnColumnFilterfunc(); onServerSideButtonItemsRequested(ListClicktnColumnFilter, myOrderBy)">
<span>{{$index+1}}</span>
<span ng-model="columnFacetname">{{y.facetName}}</span>
<span>{{y.facetValue}}</span>
</button>
</div>
</div>
angular.module('mainModule').controller('MainCtrl', function($scope, $http) {
$scope.columnFacetname = "";
$scope.ListClicktnColumnFilter = "";
$scope.ListClicktnColumnFilterfunc = function() {
$scope.ListClicktnColumnFilter = "\":\'" + $scope.columnFacetname + "\'";
};
}
the problem is that the $scope.ListClicktnColumnFilter doesn't show the $scope.columnFacetname within it, meaning that the $scope.columnFacetname is not well-binded.

In your ng-click instead of calling two different function
ng-click="ListClicktnColumnFilterfunc(); onServerSideButtonItemsRequested(ListClicktnColumnFilter, myOrderBy)"
you can declare like this
ng-click="columnFacetname = y.facetName; onServerSideButtonItemsRequested(columnFacetname , myOrderBy)"
You are trying to pass that model to another function by assigning it to ListClicktnColumnFilter in your controller
By doing in this way, you can achieve the same thing.
I have done one plunker with sample array,

Hope this helps!

How to add multiple items to a list

I'm building an app where users can add items to a list and I decided, for the sake of learning, to use Angular (which I'm very new to). So far, I've been able to successfully add a single item to that list without any issues. Unfortunately, whenever I try to add more than one without a page refresh, I get an error - specifically a "Undefined is not a function."
I've spent more time than I care to think about trying to resolve this issue and I'm hoping an expert out there can give me a hand. Here's what I have so far:
Controllers:
angular.module('streakApp')
.controller('StreakController', function($scope) {
// Removed REST code since it isn't relevant
$scope.streaks = Streak.query();
// Get user info and use it for making new streaks
var userInfo = User.query(function() {
var user = userInfo[0];
var userName = user.username;
$scope.newStreak = new Streak({
'user': userName
});
});
})
.controller('FormController', function($scope) {
// Works for single items, not for multiple items
$scope.addStreak = function(activity) {
$scope.streaks.push(activity);
$scope.newStreak = {};
};
});
View:
<div class="streaks" ng-controller="FormController as formCtrl">
<form name="streakForm" novalidate >
<fieldset>
<legend>Add an activity</legend>
<input ng-model="newStreak.activity" placeholder="Activity" required />
<input ng-model="newStreak.start" placeholder="Start" type="date" required />
<input ng-model="newStreak.current_streak" placeholder="Current streak" type="number" min="0" required />
<input ng-model="newStreak.notes" placeholder="Notes" />
<button type="submit" ng-click="addStreak(newStreak)">Add</button>
</fieldset>
</form>
<h4>Current streaks: {{ streaks.length }}</h4>
<div ng-show="newStreak.activity">
<hr>
<h3>{{ newStreak.activity }}</h3>
<h4>Current streak: {{ newStreak.current_streak }}</h4>
<p>Start: {{ newStreak.start | date }}</p>
<p>Notes: {{ newStreak.notes }}</p>
<hr>
</div>
<div ng-repeat="user_streak in streaks">
<!-- Removed most of this for simplicity -->
<h3>{{ user_streak.fields }}</h3>
</div>
</div>

Could you post the html of StreakController too? Your solution works fine in this fiddle:
http://jsfiddle.net/zf9y0yyg/1/
.controller('FormController', function($scope) {
$scope.streaks = [];
// Works for single items, not for multiple items
$scope.addStreak = function(activity) {
$scope.streaks.push(activity);
$scope.newStreak = {};
};
});
The $scope inject in each controller is different, so you have to define the "streaks" in FormController.

Your problems comes from :
.controller('FormController', function($scope) {
// Works for single items, not for multiple items
$scope.addStreak = function(activity) {
$scope.streaks.push(activity);
^^^^^^
// Streaks is initialized in another controller (StreakController)
// therefore, depending of when is instantiated StreakController,
// you can have an error or not
$scope.newStreak = {};
};
});
A better design would be to implement a StreakService, and to inject that service in the controller you need it. Of course, initializing $scope.streaks in FormController will make your code work, but that's not the responsibility of FormController to initialize this data.

I assume FormController is a nested controller of StreakController, so they share the same scope.
if that works for single object, it should work for mulitiple objects, the problems is you can't just use push to push an array of object to the streaks, you can for loop the array and add them individually or use push.apply trick. I thought the reason of Undefined is not a function. is because the Stack.query() return an element instead of an array of elements so, the method push doesn't exists on the $scope.streaks.
