Hey I have array of numbers, I am writing them using ng-repeat. When you click on some number should be pass to function passParameterToService parameter index and should be saved in service to variable this.whichBoard. But I have do something wrong, can someone tell me why ng-repeat don't work when I add service and why after click on some number, it's dont write to a variable?

In your service you were declaring this.whichBoard but inside the function you again used the same named variable. If you set this.board inside, it would probably work:
app.service('serwis', ()=> {
this.whichBoard = (index) => {
this.board = index;
};
});
Also in the calling method, you have:
<a href="#" ng-click="passParameterToService($index)">
<span ng-repeat="item in arrayIndex">{{item}}</span>
</a>
You're passing $index, which isn't a value. Also, you have the repeat inside the method call, so change it to:
<div ng-repeat="item in arrayIndex track by $index">
{{item}}
</div>

I have select and list:
<select ng-model="atndYearSelected" ng-options="year for year in atnd_years|orderBy:'-year'"
ng-change="getAttendance(selectedYear,month.number,infoList['0']['staff_id']);" class="year"></select>
<ul class="year_selection">
<li ng-repeat="month in monthsList" ng-class="{active_year : isActiveYear(month.number)}">
<a href="" ng-click="setActiveYear(month.number); getAttendance(atndYearSelected,month.number,infoList['0']['staff_id']);">
{{month.month}}
</a>
</li>
</ul>
getAttendance function works fine on ng-click inside the list. However I cant access month.number value inside ng-change. Is there any way to access month number value?
I tried to use ng-init inside of the link but it didnt work.
month is only available inside your ng-repeat within the li. Thus <select> has no access to it.
The work around to this is to store it in a scope variable when setActiveYear of li is called, and you can use this scope variabl when you want to.
$scope.setActiveYear = function(monthNumber){
//...other codes
$scope.myValue = monthNumber;
};
I have a list of posts with comments. I need to traverse through array of comments inside each of the posts on my page. I'm trying to create variable inside ngRepeat for posts which I can use like an indexer to display exact comment for each post. Due to ngRepeat creating nested scope, this variable must be unique for each iteration. But when I'm trying to change it with ng-click, it doesn't change.
My ngRepeat:
<div class="question_block col-xs-12"
ng-repeat="answer in question.content.answer track by answer.id">
is followed by <span style="display:none">{{counter=0}}</span>. And then I'm showing some items like <span>{{answer.comments[counter].user.organization.title}}</span>. When I'm trying to do something like <a href ng-click="counter++">Increment</a> nothing happens. What's the matter ?
Use ng-init="counter = 0" and attach your ng-click to a function in your controller:
<div ng-repeat="item in items track by $index" ng-init="counter=0">
{{item}} ({{counter}})
<button ng-click="clickHandler()">Increment</button>
<hr />
</div>
Then, to increment counter in the context of the event, use this.counter
$scope.clickHandler = function() {
this.counter++;
};

Yes, it has been asked before, and I've read all the answers but nothing seems to work. So I'm asking for an extra pair of eyes to see if you can find any singularity in my code that is making it not work as it should. (I tried this code and logic somewhere else and it seems to work fine). No errors in the console by the way
I am simply trying to remove an item from the view when someone clicks the x on the picture.
Here is the controller
app.controller('galleryController', ['$scope', '$http', function($scope, $http) {
$http.get('data/galleries.json').success(function(data){
$scope.galleries = data;
}).error(function(error) {
console.log(error);
});
$scope.removeGalleryItem=function(gallery){
var removedGallery = $scope.galleries.indexOf(gallery);
$scope.galleries.splice(removedGallery, 1);
};
}]);
and my view
<div class="col-xs-12 col-md-3" ng-repeat="gallery in galleries" >
<a class="gallery-item" ng-href="{{gallery.img}}" ng-class="{true:'active',false:''}[checked]"
title="Nature Image 1" >
<div class="image">
<img ng-src="{{gallery.img}}" alt="Nature Image 1"/>
</div>
<div class="meta">
<strong>{{gallery.title}}</strong>
<span>{{gallery.desc}}</span>
</div>
</a>
<ul class="gallery-item-controls">
<li><label class="check"><input type="checkbox" class="icheckbox" ng-model="checked" /></label></li>
<li><span class="gallery-item-remove"><i class="fa fa-times" ng-click="removeGalleryItem(gallery)"></i></span></li>
</ul>
</div>
Angular 1.5.8
Thanks
You can pass an $index in your click function like this.
<i class="fa fa-times" ng-click="removeGalleryItem(galleryItem, $event , $index)">
and use $scope.galleries.splice(index, 1); inside your click function removeGalleryItem, make sure you have index parameter too like this.
$scope.removeGalleryItem = function(gallery , event, index){
$scope.galleries.splice(index, 1);
};
Hope this helps..
After doing some research I think the problem is that galleryController is defined somewhere in your markup but the elements in the gallery are not inside of where that controller is defined.
Referring to http://joli.sitedev.online/#/gallery. In file slidesController.js where galleryController is defined I put a break here and the code pauses:
I also put a break point here but the code does not pause when clicking on a delete button:
Looking at the markup I can't see any sign of ng-controller="galleryController" so I can't see how galleries in the ng-repeat is populated:
Maybe it is through this:
If it is through that then it would explain things as that directive has its own controller. Any further information would help and I'm sure we can clear this up.
If I understood correctly your question, if you want to delete a particular element both from DOM and Array containing these particular elements you can do the following:
<!-- Intercept that particular Element with $event-->
<i class="fa fa-times" ng-click="removeGalleryItem(galleryItem, $event)">
Lets supposing you are repeating some galleryItems and they have a name property.
And on your controller:
$scope.removeGalleryItem(galleryItem, $event){
//Save galleryItem Name
var itemName = $($event.currentTarget).name(); // if it has it on html
var itemName = galleryItem.name; // if it has a property
//Get the target and remove it
$($event.currentTarget).remove();
//Using lodash, loop through your array and remove that exact object from it.
//Ofc you can do a normal loop through it.
$scope.galleries = _.remove($scope.galleries, function(n) {
return n != itemName;
});
//Then, if the change does not happen in your DOM
$scope.$apply();
}
Hope I've been helpful.
I have made some changes to fix this issue and you can check it at this link.
The problem here was that there was a typo in the html snippet that was calling the removeGalleryItem(galleryItem, $event). The parameter name should have been gallery, not galleryItem, since there is no such object by the name galleryItem, hence inside this method, the parameter value was undefined. Once I fixed it, I was able to get the gallery object within the removeGalleryItem method and the following code worked absolutely fine:
$scope.removeGalleryItem=function(gallery){
var selectedGallery = $scope.galleries.indexOf(gallery);
$scope.galleries.splice(selectedGallery, 1);
};
Also note that, I have removed the $event attribute from the method declaration and from the html method call as we didn't need it in the above mentioned approach.
<i class="fa fa-times" ng-click="removeGalleryItem(gallery)"></i>
<div (ng-repeat='item in items') >
{{item.name}} //works
{{item["name"]}} // works
</div>
how do i repeat item[property] dynamically without using ".name" or ['name']?
To dynamically go through properties, you're going to need to call Object.keys(item) and then iterate through them. It's best to prune your data from within your controller, to minimize the finagling you'll need to do within your HTML.
If you do want to try to do this within your HTML-Angular structures, you could define:
$scope.returnAllKeyValues = function(obj){
var x = Object.keys(obj),
arr = [];
for(var i = 0; i<x.length; i++){
arr.push(obj[x[i]]);
}
return arr;
}
What this function does is it takes in your JSON object, then parses through it and collects all the values for every key within it.
Then, within your HTML, you can write something like this:
<h3>FIFA Mactch Summary:</h3>
<div ng-app ng-controller="MyCtrl">
<ul>
<li ng-repeat="item in items">
<span ng-init="keyValues = returnAllKeyValues(item)">
<span ng-repeat="keyValue in keyValues">{{key}} </span>
</span>
</li>
</ul>
</div>
Here you see, within your original ngRepeat, we initialized the array keyValues with all the values from item's keys via the function defined above. Then, ng-repeat through that, and you have everything printed without knowing what they are.
Here is a Fiddle with it working:

This was what i was looking for....Thanks

I use routing to load different templates into a ngView. One of the templates has a simple controller which contains an array of contacts. What I'm trying to do here is as simple as by clicking a link (ngclick) call a function and add a new object into the array which I expect will be reflected in my UI.
It's something like this:
$scope.contacts = [{name='', email=''}];
<li ng-repeat="con in contacts">
<input type="text" ng-model="con.name"/>
<input type="email" ng-model="con.email"/>
</li>
<li>
<a href ng-click="addContact()">add</a>
</li>
$scope.addContact = function() {
$scope.contacts.push( {name='', email=''} ); //-- i can use either $scope or this to reference the array and works.
}
So, the UI renders well with the initial value, the addContact function is invoked on click and I see the value is pushed (length = 2) but then the function ends the array seems to be reset to one element (lenght = 1) after angularjs evaluation.
I'm not sure if this is occurring because I use ngView. I mean, I reviewed this example (http://code.angularjs.org/1.0.3/docs/api/ng.directive:ngController) and I don't see much differences of what I'm trying to do here, the diff is that I use routing with ngView.
fiddle: http://jsfiddle.net/fdDph/
Help is much appreciated.
In your Fiddle, you are resetting the array length to 1 in the ng-show:
<span ng-hide="contacts.length = 1">
Do this and it will work:
<span ng-hide="contacts.length == 1">
{name='', email=''} is wrong syntax btw, it should be {name:'', email:''}
