I wanna get selected item in Ionic checkboxes. So, when user checks checkbox(es), I wanna know which book(s) he/she has selected.
Here are my code snippets:
<ion-item ng-repeat="book in data.books">
<div style="margin-left:110px;margin-right:10px;">
{{book.name}}
</div>
<li class="item item-checkbox checkbox-balanced">
<label class="checkbox">
<input type="checkbox">
</label>
</li>
</ion-item>
When run the code, it looks like this:
I wanna use ng-model but I do not know how to use it. Can someone help me please as I am new to Ionic and AngularJS, THANKS!
UPDATE:
I am extremely sorry that I did not provide the controller's code snippet, here are the codes:
.controller('DetailsCtrl', function ($scope, $http) {
$http.get("") // some webservice url
.then(function (response) {
$scope.data = response.data;
});
});
You can have a variable for checked in each value and bind that as a model variable to the check box
DEMO
var clubApp = angular.module('clubApp', ['ionic'])
clubApp.controller('ctrlPlayer', ['$scope', function($scope) {
$scope.books = [{
"name": "And the goog news is",
"checked": false
}, {
"name": "Girl on the train",
"checked": false
}];
$scope.getselected = function(){
angular.forEach($scope.books,function(key,value){
if(key.checked ==true)
{
alert(key.name);
}
});
}
}]);

I'm creating a button to check all checkboxes. The problem is that my "all check" button doesn't work to check off all checkboxes when I click the button.
How can I do this?
angular.module('myapp', [])
.controller('MainController', ['$scope', function($scope) {
$scope.allcheck = function(){
angular.forEach($scope.checkboxes, function(item){
item.selected = event.target.checked;
});
};
}]);

<script src="myscript.js"></script>
</head>
<body>
<h1>AngularJS</h1>
<div ng-controller="MainController">
<button ng-click="allcheck()">all check</button>
<input type="checkbox">a
<input type="checkbox">b
<input type="checkbox">c
</div>
</body>
</html>
When you start with Angular you should think and do in angular.
First you define your model:
$scope.selected = [false, false, false];
Then you render your model into view, using repeat. (I don't remember the syntax)
<div ng-repeat="item in selected">
<input type="checkbox" ng-model="item" />
</div>
Then you implement check all by just simply changing the model.
$scope.checkAll = function() {
for (var i = 0; i < $scope.selected.length; i++) {
$scope.selected[i] = true;
}
}
Don't think like you are working with JQuery, think like MVC.
I have built a small application to switch languages
I create a controller where I get the value from ng-model and then assign the value to a variable. I need help to pass this value in app.config.
Code:
var app = angular.module("myApp", ['pascalprecht.translate']);
var name = 'Anuj';
app.controller("translateController", ["$scope", "$translate", function($scope, $translate) {
$scope.changeValue = function() {
name = $scope.textname;
$translateProvider.translations('en', en_translations);
}
$scope.changeLanguage = function(lang) {
$translate.use(lang);
}
}]);
app.config(["$translateProvider", function($translateProvider) {
var en_translations = {
"language": name,
"greeting": "Welcome Dinesh"
}
var sp_translations = {
"language": "Selected Language Spanish",
"greeting": "Bienvenida Dinesh"
}
$translateProvider.translations('en', en_translations);
$translateProvider.translations('sp', sp_translations);
$translateProvider.preferredLanguage('en');
}]);

Ive been trying for the past couple of hours but for I can't seem to figure out why I can access $scope.FeatureGroup to add to my url
Any ideas?
angular.module('ngRepeat', ['ngAnimate',]).controller('repeatController', function($scope, $http) {
$scope;
$scope.FeatureGroup = 50000;
$scope.ShowMeData = function($scope){
var url = 'URLHERE' + $scope.FeatureGroup;
$http.get(url).success(function(data) {
console.log(data);
//$scope.Object = data;
});
}
});

{{FeatureGroup}}
<!-- ngIf: Objects.length === 0 -->
<!-- ngRepeat: feature in Object | filter:q as results -->
</ul>

That is because of following line. You are overriding the $scope variable:
$scope.ShowMeData = function($scope){
You are really not passing any scope variable while calling the function
ng-keyup="ShowMeData()".
Just change it to:
$scope.ShowMeData = function(){
and it should work.
I want to pass a parameter to the next page onclick of a button.
I have tried as below; on the first page I have a textarea and I want to pass that value to the next page on button click using AngularJS, I have tried as below, but it's not working.

Please can you help me to figure it out?
First read this https://docs.angularjs.org/guide/$location
Remove send() function
function FirstCtrl($scope, $location, theService) {
$scope.thing = theService.thing;
$scope.name = "First Controller";
$scope.send = function(){
$location.path('/second').search({id: 12});
};
}
<input type="button" value="send" ng-click="send()">
To send the parameter to next page you have to use $location service.
$location.path('/second').search({id: 12});
But again this will not work for you as you are not using AngularJS for routing , you are using JS for that. I suggest following this PhoneCatApp to learn Angular basics
I'm learning how to develop with AngularJS for the first time for a class and I am trying to understand why I'm not getting an updated value of the length property and was hoping someone could help me understand why my code is not working and what I should be doing for it to update.

<title>Grocery List</title>
<script src="js/angular.min.js"></script>
<script src="js/app.js"></script>
</head>
<body ng-app>
<h1>My Grocery List</h1>
<div ng-controller="MYController">
<input type="text" ng-model="listItem" placeholder="Add Grocery Item" />
<input type="submit" ng-click="addItem()" value="Save" />
<h2>Items</h2>
<ul ng-show="itemArray.length">
<li ng-repeat="listItem in itemArray">
{{ listItem }}
<buton ng-click="deleteItem(listItem)">X</buton>
</li>
</ul>
</div>
</body>
</html>
Code in app.js
function MYController($scope) {
$scope.listItem;
$scope.itemArray = [];
$scope.addItem = function() {
$scope.itemArray.push($scope.listItem);
$scope.listItem = '';
}
$scope.deleteItem = function(deletedItem) {
var idx = $scope.itemArray.indexOf(deletedItem);
$scope.itemArray.splice(idx, 1);
}
}
In Angular when you make controller then it need to assign with a module
So here you will made your controller in js like below
angular.module('todoApp', [])
.controller('MYController', ['$scope', function($scope) {
$scope.listItem;
$scope.itemArray = [];
$scope.addItem = function() {
$scope.itemArray.push($scope.listItem);
$scope.listItem = '';
}
$scope.deleteItem = function(deletedItem) {
var idx = $scope.itemArray.indexOf(deletedItem);
$scope.itemArray.splice(idx, 1);
}
});
And in HTML bootstrap angular like below in body tag and use your controller
<body ng-app="todoApp">
See here for reference https://angularjs.org/#add-some-control
I think there may be some confusion between the listItem in ng-model="listItem" and ng-repeat="listItem in itemArray". Try changing the second one to a different variable name like this:
<li ng-repeat="item in itemArray">
{{ item }}
<button ng-click="deleteItem(item)">X</button>
</li>
Also, change that first line in your controller $scope.listItem; to $scope.listItem = '';.
assign module to angular app using this code:
var app = angular.module('plunker', [])
and
<html ng-app="plunker">
