add 1 to value after submission to databse with angular - javascript

I'm working on a project where user can like comment made by users. and what i want to achieve is when a user likes a comment on a page by default + 1 should be added to the total comments made. Below is my script my it doesn't work
.controller('feedsctrl',['$scope','$http',function($scope,$http){
$http.get('http://localhost/vivalooks/app_ion/like.php').success(function(data){
//$scope.feeds = console.log(data) ;
$scope.feeds = data;
$scope.lovepic = function() {
event.preventDefault();
$http.post("http://localhost/vivalooks/app_ion/scripts/comment.php",
{
'u_pic_id': $scope.u_pic_id,
'pic': $scope.pic
}
).success(function(data,status,headers,config){
console.log(data)
$scope.comment_total=$scope.comment_total+1;
});
}
});
}])
HTML
<ion-content>
<div ng-controller="feedsctrl" class="list card has-subheader" ng-repeat="item in feeds">
{{item.comment_total}} Comments
</ion-content>

Issue with your code is that you are trying to update the $scope.data[item].comments with $scope.comments. These both are different variable in angular controller scope. you should perform the addition in the same scope variable to get it reflected on the view. You can achieve this by slight modification in your code
html
<ion-content>
<div ng-controller="feedsctrl" class="list card has-subheader" ng- repeat="item in feeds trach by $index">
<img src="item.src" ng-click="lovepic($index)">
{{item.comment_total}} Comments
</div>
</ion-content>
in the controller.
$scope.lovepic=function(index) {
event.preventDefault();
$http.post("http://localhost/vivalooks/app_ion/scripts/comment.php",
{'u_pic_id':$scope.feeds[index].u_pic_id,'pic':$scope.feeds[index].pic})
.then(function(data,status,headers,config){
$scope.feeds[index].comment_total == undefined ? 1 : $scope.feeds[index].comment_total +1;
});
}

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;
})

How to avoid AngularJS ui grid showing 'no-data' message while api is loading

I have angularjs ui-grid, i used below condition to check availability of data, which means if data is not there i am showing 'no data available' message.
The problem is my api call is little slow because of huge data, so while this call in process no data available will show, I need to hide it in angular way initially. I cant use disply:none initially because there are so many conditions in grid filter after which that message will have to show, so every time i cant say disaply:none and display:block. Any help will be very helpful thank you.
html
<div ng-controller="MainCtrl">
<div ui-grid="gridOptions" ui-grid-selection ui-grid-exporter class="grid">
<div class="watermark" ng-show="!gridOptions.data.length">No data available</div>
</div>
</div>
Sample js call
$http.get('https://cdn.rawgit.com/angular-ui/ui-grid.info/gh-pages/data/100.json')
.success(function(data) {
data = {"data": []};
$scope.gridOptions.data = data;
});
Please see the demo in below plunker
Add a new variable in controller:
$scope.noData = false;
Change your api call as:
$http.get('https://cdn.rawgit.com/angular-ui/ui-grid.info/gh-pages/data/500.json')
.success(function(data) {
if (data.length > 0) {
$scope.gridOptions.data = data;
} else {
$scope.noData = true;
}
});
in the view change:
<div class="watermark" ng-show="noData">No data available</div>
Test Plunker
Easy doing by using another state handler variable e.g. $scope.loading:
<div ng-controller="MainCtrl">
<div ui-grid="gridOptions" ui-grid-selection ui-grid-exporter class="grid">
<div class="watermark"
ng-show="!gridOptions.data.length && !loading">No data available</div>
<div class="watermark"
ng-show="loading">loading ...</div>
</div>
</div>
Controller
$scope.loading = true;
$http.get('https://cdn.rawgit.com/angular-ui/ui-grid.info/gh-pages/data/100.json').success(function(data) {
$scope.loading = false;
data = {"data": []};
$scope.gridOptions.data = data;
});

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

adding array elements to another array

I have a very big list which is an array named leagues, I need to allow the user to take the elements on that array(list) , and choose those as favorites by clicking a button
$scope.favoriteLeagues = [];
$scope.favoriteLeague = function(league) {
$scope.favoriteLeagues.push(league);
}
so I want to know what am I doing wrong ? the function sometimes allows me to add one as favorite, but once I click on the second one, I got a message of something undefined, and also, the binding is not working, I am unable to see the {{favoriteLeagues.name}} printed.
UPDATED AS REQUESTED
<div>
<strong>Favorites</strong>
{{favoriteLeagues.name}}
</div>
<ion-option-button class="button-light icon ion-star"
on-tap="favoriteLeague(league)">
</ion-option-button>
<div ng-repeat="sport in sportsFilter = (sports | filter:query)">
<strong>{{sport.name}}</strong>
</div>
<ion-item ng-repeat="league in sport.leagues">
<div>{{league.name}}</div>
</ion-item>
</ion-list>
here the controller:
.controller('SportsController', function($scope, $state,
AuthFactory, SportsFactory) {
$scope.favoriteLeagues = [];
$scope.sports = [];
AuthFactory.getCustomer().then(function(customer) {
$scope.customer = customer;
SportsFactory.getSportsWithLeagues(customer).then(function(sports) {
if (sports.length) {
$scope.sports = sports;
}
$scope.isSportShown = function(sport) {
return $scope.shownSport === sport;
};
$scope.favoriteLeague = function(league) {
$scope.favoriteLeagues.push(league);
}
};
});
You haven't pasted the full html, but it should look something like this:
<!-- Use ng-app to auto-bootstrap an AngularJS application-->
<!-- Use ng-controller to attach your view with your SportsController controller -->
<ion-list>
<div>
<strong>Favorites</strong>
<!-- Looping through all the favourite leagues-->
<div ng-repeat="favouriteL in favoriteLeagues">
{{favouriteL.name}}
</div>
</div>
<!-- Looping through all the sports -->
<div ng-repeat="sport in sportsFilter = (sports | filter:query)">
<!-- Bind the sport name -->
<strong>{{sport.name}}</strong>
<!-- Looping through all the leagues -->
<ion-item ng-repeat="league in sport.leagues">
<!-- Display a button which on tap will call favoriteLeague function -->
<ion-option-button class="button-light icon ion-star" on-tap="favoriteLeague(league)">
</ion-option-button>
<!-- Bind the name of the league -->
<div>{{league.name}}</div>
</ion-item>
</div>
</ion-list>
Don't forget to attach the view with your controller using ng-controller.
I can't help you much with angular.js, I've never used it, but the fact that you are accidentally replacing the array with the function probably doesn't help. ng-repeat is trying to loop through favoriteLeagues but fails because that's a function! Look at the comments I put in your code.
$scope.favoriteLeague = []; // creates an array
$scope.favoriteLeague = function(league) { // replaces the array with a function!!!
$scope.favoriteLeagues.push(league); // suddenly leagues takes an S ?
}
To avoid this type of error, you should respect a naming convention for your functions. I like to use action words and verbs for functions. I only use plural forms on arrays and related functions. Here's what I'd do in your case:
$scope.favoriteLeagues = [];
$scope.addToFavoriteLeagues = function(league) {
$scope.favoriteLeagues.push(league);
}
You need to attach your controller to the html in order for the bind to work, usually at the top level parent element, e.g a div, containing the ngrepeat markup.

AngularJS - Cannot set scope value into template

I have following function:
$scope.setDetailToScope = function(data) {
$scope.$apply(function() {
//$scope.order = data;
$rootScope.order = data;
setTimeout(function() {
$scope.$apply(function() {
//wrapped this within $apply
$scope.order = data[0];
console.log('message:' + $scope.order);
console.log($scope.order);
});
}, 100);
});
};
"
console.log($scope.order);
Gives me values which has been set into scope.
But i cannot get these values in template.
<!-- DEBUG DIV -->
<div class="debugDiv" ng-show="$root.debugable == true">
{{columns}}
</div>
<div data-ng-controller="OrdersCtrl" ng-init="initData()">
<div id="orders_grid" >
</div>
</div>
<!-- GRID TOOLBAR BUTTON TEMPLATE -->
<script id="template" type="text/x-kendo-template">
<a class="k-button" href="\#/orders/create">Add</a>
</script>
<!-- ORDER DETAIL DIV -->
<div class="container" id="orderDetail" data-ng-controller="OrdersCtrl" ng-if="'detailSelected == true'" xmlns="http://www.w3.org/1999/html">
<!-- DEBUG DIV -->
<div class="debugDiv" ng-show="$root.debugable == true">
{{order}} <!--NOT WORKING-->
</div>
If i tried to add values into rootscope it works, but in this case i cannot get value into ng-model.
What i'm doing wrong please?
Many Thanks for any help.
EDIT:
If i tried solution wit $timeout i got on console.log($scope.order);
following object which is not passed into the template:

well I'm not sure why you are using a setTimeout with scope apply, to me is safer to use a $timeout since it fires another digest cycle,
try something like
$scope.setDetailToScope = function(data) {
$timeout(funtion(){
//$rootScope.order = data; try either data or data[0]
$scope.order = data[0];
},100);
};
please note that calling nested apply methods can run into some problems with the angularjs digest cycle you may get an error like "digest already in progress" so put attention to it.
NOTE:
it seems like you got some dirty data there, so try to do a map between the data and the scope
$scope.order ={};
$scope.order.uid = data.uid;
$scope.order.orderNumber = data.orderNumber //and so on
in your template try something like:
<div class="debugDiv">
<p> {{order.uid}} </p>
<p> {{ order.orderNumber}} </p>
</div>
this could be a little bit rustic but it worth to try it out.
