Remove "checked" item from array with angularJS - angularjs

I've got a list with todo's, in that list I can check them if they are done.
If they are done I want to remove them from my list with angularJS.
<body>
<h2>Todo</h2>
<div ng-controller="TodoListController as todoList">
<span>{{todoList.remaining()}} van de {{todoList.todos.length}} nog te doen</span>
<ul class="unstyled">
<li ng-repeat="todo in todoList.todos">
<label class="checkbox">
<input type="checkbox" ng-model="todo.done">
<span class="done-{{todo.done}}">{{todo.text}}</span>
</label>
</li>
</ul>
<form name="formaddtodo" ng-submit="todoList.addTodo()">
<input type="text" ng-model="todoList.todoText" ng-minlength="1" size="30"
placeholder="Voeg nieuwe todo toe" required>
<input class="btn-primary" type="submit" value="voeg toe">
</form>
<input class="btn-danger" type="button" value="verwijder" ng-click="todoList.removeItem()">
</div>
</body>
with the removeItem function I want to delete the checked items from the list.
angular.module('todoApp', [])
.controller('TodoListController', function() {
var todoList = this;
todoList.todos = [{text:'learn AngularJS', done:false},
{text:'build an AngularJS app', done:false}];
todoList.addTodo = function () {
todoList.todos.push({text: todoList.todoText, done: false});
todoList.todoText = '';
};
todoList.remaining = function () {
var count = 0;
angular.forEach(todoList.todos, function (todo) {
count += todo.done ? 0 : 1;
});
return count;
};
todoList.removeItem = function() {
todoList.todos.splice(???)
}
});
It would be awesome if someone can explain it to me!

todoList.removeItem = function() {
angular.forEach(todoList.todo, function(todo, key) {
if(todo.done)
todoList.todos.splice(key, 1);
});
}
You can use underscore filter
todoList.removeItem = function() {
todoList.todos = _.filter(todoList.todos, function(todo) {
return !todo.done;
});
}

You could store your todos in a new array and empty the current array and only add back todos that aren't done something like this?:
todoList.removeItem = function() {
var oldTodos = toDoList.todos;
toDoList.todos =[];
angular.forEach(oldTodos, function(todo){
if (!toDoList.todos.done)
toDoList.todos.push(todo);
});
}

AngularJS multi screen validation on last step

I have an angularJS application. I have implemented a generic workflow using $routeProvider, templateUrl & Controllers.
Each step(screen) is verified when user click on next button and moves to the next step if validation passes. If validation fails user is required to fix all the error, displayed on the screen, before moving to next step.
When user has visited all the screens(passed validation for each screen) all the breadcrumbs get enabled and now user can move freely between those steps/breadcrumbs.
Requirement:
Now I want to allow user to move freely between steps by clicking on the breadcrumbs and when user clicks on the lodge button, on the last step, validation for current as well as for all previous steps should be invoked, and clicking on the error user should be able taken to the relevant step/screen.
Also I want to keep the functionality of validating the individual steps on the click of next button.
As you can see each screen has a separate controller along with the scope.
Once user move from one step to another it can't access the previous scope.
Initially I thought of storing scope of each screen in an array, but once I move between steps new scope is created (as it should) and only current step has a form with valid data model and "valid" flag as false.
Form object at current step
Form object of other screen without and fields attached
I'm not very well versed with Angularjs and trying to get some idea weather
Is it possible what I'm trying to achieve keeping the existing functionality intact. (My understanding is that I can't have a single controller since I need to keep the functionality of validating each step individually)?
Is there a better way to trying to achieve this functionality?
PS: Sadly I can't upgrade to newer version of Angular.
Any help will be highly appreciated.
Form Validation
validator.validate = function($scope, submitCallback, additionalOptions) {
var options = {};
$.extend(options, commonOptions, additionalOptions);
var form = $scope[options.formName];
hideErrorMessages(options.errorContainerSelectorId);
if (form.$valid) {
submitCallback();
return;
}
showErrorMessages({message: composeAngularValidationErrors(form),
errorContainer: $('#' + options.errorContainerSelectorId)});
};

Get the value of dynamic check boxes in angular js when submitting the form

In my HTML form there are 5 check boxes. How can I check which check boxes are checked or not at the time of the form submission?
I am using this little piece of code. Feel free to take it.
In your controller:
$scope.sentinel = [];
$scope.toggleSelection = function(value) {
// Bit trick, equivalent to "contains"
if (~$scope.sentinel.indexOf(value)) {
var idx = $scope.sentinel.indexOf(value);
$scope.sentinel.splice(idx, 1);
return;
}
$scope.sentinel.push(value);
};
Then in your HTML:
<span ng-repeat="key in $scope.yourarray">
<md-checkbox style="margin-left:30px;" aria-label="Select item"
ng-click="toggleSelection(key)"><span>{{ key }}</span></md-checkbox>
<br/>
</span>
This allows you to have an array of any size and using the sentinel array to register already checked values. If you check again a box, the toogleSelection will prevent you from adding again a value.
You can use the Checklist-model of Angular.js. It is very useful:
var app = angular.module("app", ["checklist-model"]);
app.controller('Ctrl1', function($scope) {
$scope.roles = [
'guest',
'user',
'customer',
'admin'
];
$scope.user = {
roles: ['user']
};
$scope.checkAll = function() {
$scope.user.roles = angular.copy($scope.roles);
};
$scope.uncheckAll = function() {
$scope.user.roles = [];
};
$scope.checkFirst = function() {
$scope.user.roles.splice(0, $scope.user.roles.length);
$scope.user.roles.push('guest');
};
$scope.showCheckedOnes = function() {
var checkedBoxes = "";
for (var i = 0; i < $scope.user.roles.length; i++) {
checkedBoxes += $scope.user.roles[i] + " ";
}
alert(checkedBoxes);
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://vitalets.github.io/checklist-model/checklist-model.js"></script>
<div ng-app="app">
<div ng-controller="Ctrl1">
<label ng-repeat="role in roles">
<input type="checkbox" checklist-model="user.roles" checklist-value="role"> {{role}}
</label>
<div>
<div>
<button ng-click="checkAll()" style="margin-right: 10px">Check all</button>
<button ng-click="uncheckAll()" style="margin-right: 10px">Uncheck all</button>
<button ng-click="checkFirst()" style="margin-right: 10px">Check first</button>
<button ng-click="showCheckedOnes()" style="margin-right: 10px">Show checked ones</button>
You can define the array value and map to html.
$scope.checkbox = [];
HTML
<input ng-model="checkbox[0] type="checkbox" />
<input ng-model="checkbox[1] type="checkbox" />
<input ng-model="checkbox[2] type="checkbox" />
<input ng-model="checkbox[4] type="checkbox" />
Or you can define checkbox as object and change checkbox[index] to checkbox[name].

Besides my HTML i also have a product.Controller and a products.service. The productController looks like this:
(function(){
function productController($scope, productsService, cartService, $routeParams){
var modelProduct = function(productArray){
$scope.product = productArray[0];
}
productsService.getProduct($routeParams.id)

$scope.createProduct = function() {
var product = {
id : this.id,
brand : this.brand,
content : this.content,
alcohol : this.alcohol,
price : this.price,
category : this.category
}
console.log(product);
productsService.saveProduct(product);
}
}
angular
.module("Main.product", [])
.controller("productController", productController);
})();
and my productsService looks like this:
(function(){
"use strict";
var productsService = function($http){
var categoriesSelected = new Array();
var products = new Array();
var getProducts = function(){
/* Hent fra den lokale grillbar
return $http.get("./data/products.json")

I hope someone out there can help me!
You don't appear to be exporting saveProduct as a public method of your service:

getProducts: getProducts,
getProduct: getProduct,
getCategories: getCategories,
getCategoriesSelected: getCategoriesSelected,
productFilter: productFilter,
categoryChange: categoryChange,

var app = angular.module("app", ["firebase"]);
app.value('newsURL', 'https://XXX.firebaseio.com/XXX/');
app.factory('newsFactory', function($firebase, newsURL) {
return $firebase(new Firebase(newsURL)).$asArray();

$scope.uncheckAll = function() {

plunker here
I don't know how to remove the items by checkbox or how to make the "checkAll" button work.
I will be appreciate if someone could tell me your answer.
Here is function you would need to check/uncheck and for removing items:
$scope.checkAll = function() {
$scope.newslist.forEach(function(el) {
el.checked = true;
$scope.newslist.$save(el);
});
};
$scope.uncheckAll = function() {
$scope.newslist.forEach(function(el) {
el.checked = false;
$scope.newslist.$save(el);
});
}
$scope.remove = function() {
$scope.newslist.forEach(function(item) {
if (item.checked) {
$scope.newslist.$remove(item);
}
});
};

I added checked property for ngModel directive.
HTML becomes:
<li ng-repeat="item in newslist">
<input type="checkbox" ng-model="item.checked">{{item.newsTitle}}
</li>
<button ng-click="checkAll()">check all</button>
<button ng-click="uncheckAll()">uncheck all</button>
<button ng-click="remove()">Remove</button>

Simple check all not working in AngularJS

I am trying to include a check all for my todo list, but once I hit toggleAll() it gets unchecked right away, plus it unchecks whichever one is already checked.
I really couldn't figure out why this behavior, perhaps some other things in the page are interfearing. A simple version of what I have included here is in this jsfiddle http://jsfiddle.net/TKVH6/487/ and it is working.
<section id="main">
<input id="toggle-all" type="checkbox" ng-model="checkAll" ng-click="toggleAll()">
<label for="toggle-all">Mark all as complete</label>
<ul id="todo-list">
<li ng-repeat="todo in todos" ng-class="{'completed': todo.isCompleted=='true'}" class="editing">
<div class="view" >
<input class="toggle" type="checkbox" ng-click="complete(todo)" ng-model="todo.isCompleted" ng-checked="todo.isCompleted" ng-true-value="'true'" ng-false-value="'false'">
<label ng-hide="isEditing" ng-dblclick="isEditing = !isEditing">{{todo.title}}</label>
<button class="destroy" ng-click="remove(todo)"></button>
</div>
<input class="edit" ng-show="isEditing" ng-model="todo.title" ng-blur="isEditing = !isEditing;edit(todo);">
</li>
</ul>
</section>
Controller
$scope.toggleAll = function () {
if ($scope.selectedAll) {
$scope.selectedAll = true;
} else {
$scope.selectedAll = false;
}
angular.forEach($scope.todos, function (todo) {
todo.isCompleted = $scope.selectedAll;
});
};
EDIT 1
$scope.toggleAll = function() {
for(i in $scope.todos) {
$scope.todos[i].isCompleted = $scope.checkAll;
}
};
Any help is appreciated.
SOLVED! Treating the boolean as string solved it. That is because the server saves the boolean values as strings.
$scope.toggleAll = function() {
for(i in $scope.todos) {
$scope.todos[i].isCompleted = "" + $scope.checkAll;
}
};
At this point ng-checked="{{todo.isCompleted}} needs to be back since it is not a boolean.
