I have an object like so:
$scope.group = {
"Jim Jenkins": {
"Blue": {
"Circle": [
"Item1",
"Item2",
"Item3"
]
}
},
"Rachel Smith": {
"Blue": {
"Circle": [
"Item 1"
]
},
"Red": {
"Circle": [
"Item 1",
"Item 2"
]
}
}
}
I created a nested ng-repeat function that cycles through the object and displays it.
<script type="text/ng-template" id="group.html">
<ul style="padding:10px;">
<li type="none" ng-repeat="(i, c) in group">
<div ng-click="test(i)" style="background-color:#fff;padding:5px;" ng-if="i.length > 0">{{ i }}</div>
<div ng-click="test(c)" style="background-color:#fff;padding:5px;margin-bottom:5px;" ng-if="!i.length">{{ c }}</div>
<div ng-switch on="i.length > 0">
<div ng-switch-when="true">
<div ng-init="group = c;" ng-include="'group.html'"></div>
</div>
</div>
</li>
</ul>
</script>
<div ng-include="'group.html'" ng-model="group"></div>
My only issue is, now I have now way of linking back to the original $scope.group object. I have a ng-click where I display the items and I'd like to be able to know where this element is located (so I know what the parent is, know how many levels in, add more items, etc).
Does anyone know how I can achieve this?
Try like this
var app = angular.module("app", []);
app.controller('mainCtrl', function($scope) {
$scope.isArray = angular.isArray;
$scope.group = [{
"Jim Jenkins": {
"Blue": {
"Circle": [
"Item1",
"Item2",
"Item3"
]
}
},
"Rachel Smith": {
"Blue": {
"Circle": [
"Item 1"
]
},
"Red": {
"Circle": [
"Item 1",
"Item 2"
]
}
}
}]
});

</li>
</ul>

</li>
</div>
</script>
<div ng-include=" 'dummy.html'"></div>

In my DB I have Datastructure like this
"Projects":[{
"Year2016":[{"Name": "Project1"},{"Name": "Project2"}],
"Year2017":[{"Name": "Project1"},{"Name": "Project2"}]
}]
with ng-repeat i go
ng-repeat="year in Projects"
<b>{{year | limitTo:4:6}}</b>
instead of 2016 i get the whole {"Year2016":.....}
if i put the query response in the code as a string it works as suspected but
for some reason the limitTo is not working on the new ng-repeat "variable"
Is it possible at all?
you should use a (key, value) syntax ng-repeat to loop through json object array with the keys.
refer the below example:
angular.module("app", [])
.controller("myCtrl", function($scope) {
$scope.data = {
"Projects": [{
"Year2016": [{
"Name": "Project1"
}, {
"Name": "Project2"
}],
"Year2017": [{
"Name": "Project1"
}, {
"Name": "Project2"
}]
}]
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<div ng-app="app" ng-controller="myCtrl">
<div ng-repeat="project in data.Projects">
<div ng-repeat="(key, value) in project">
<b>{{key | limitTo:4:4}}</b>
<div ng-repeat="item in value">
<span>{{item.Name}}</span>
</div>
</div>
</div>
</div>
last field id for starting index so your ng repeat should be
ng-repeat="year in Projects"
<b>{{year | limitTo:4:4}}</b>
I'm a beginner in Angular so I hope someone to help me!
This is my script.js
ar app = angular.module('computer', ['ngRoute'])
.config(['$routeProvider',function($routeProvider) {
$routeProvider
.when('/main', {
templateUrl : 'main.html',

})
.when('/service', {
templateUrl : 'service.html',
controller : 'ServicesCtrl'
})
.otherwise({redirectTo:'/main'});
}])
.controller('MainCtrl', ['$scope', function($scope){
}])
.controller('ServicesCtrl', ['$scope','$http', function($scope,$http){
$http.get('serviceData.json').then(function(response){
console.log(response);
$scope.services = response.data;
});
}]);
and this is service.html
<div class="row">
<div class="col-md-12">

<div ng-repeat="serv in services">
<div class="row service">
<div class="col-md-2">

<div class="col-md-10">
<h3>{{ serv.id : serv.name }}</h3>
<p>{{serv.Description}}</p>
<button class="btn btn-primary">Read More…</button>
</div>
</div>
</div>
</div>
and serviceData.json

}, {
"id": 3,
"name": "Reparation and Reset",
"Description": "Reparation and Reset of your hardware"
}]
But I have this error in console
angular.min.js:118 Error: [$parse:syntax] http://errors.angularjs.org/1.5.8/$parse/syntax?p0=%3A&p1=is%20an%20unexpected%20token&p2=9&p3=serv.id%20%3A%20service.name&p4=%3A%20service.name
and anything display in screen.
Thank you for help !
You have to use the following line:
<h3>{{ serv.id : serv.name }}</h3>
like this:
<h3>{{ serv.id}} : {{serv.name }}</h3>
I have just started learning Angular JS and created some basic samples however I am stuck with the following problem.
I have created 2 modules and 2 controllers.
shoppingCart -> ShoppingCartController
namesList -> NamesController
There are associated views for each controller. The first View renders fine but second is not rendering. There are no errors.
http://jsfiddle.net/ep2sQ/
Please help me solve this issue.
Also is there any possibility to add console in View to check what values are passed from Controller.
e.g. in the following div can we add console.log and output the controller values
<div ng-app="shoppingCart" ng-controller="ShoppingCartController">
</div>
So basically as mentioned by Cherniv we need to bootstrap the modules to have multiple ng-app within the same page. Many thanks for all the inputs.
var shoppingCartModule = angular.module("shoppingCart", [])
shoppingCartModule.controller("ShoppingCartController",
function($scope) {
$scope.items = [{
product_name: "Product 1",
price: 50
}, {
product_name: "Product 2",
price: 20
}, {
product_name: "Product 3",
price: 180
}];
$scope.remove = function(index) {
$scope.items.splice(index, 1);
}
}
);
var namesModule = angular.module("namesList", [])
namesModule.controller("NamesController",
function($scope) {
$scope.names = [{
username: "Nitin"
}, {
username: "Mukesh"
}];
}
);
angular.bootstrap(document.getElementById("App2"), ['namesList']);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular.min.js"></script>
<div id="App1" ng-app="shoppingCart" ng-controller="ShoppingCartController">
<h1>Your order</h1>
<div ng-repeat="item in items">
<span>{{item.product_name}}</span>
<span>{{item.price | currency}}</span>
<button ng-click="remove($index);">Remove</button>
</div>
</div>
<div id="App2" ng-app="namesList" ng-controller="NamesController">
<h1>List of Names</h1>
<div ng-repeat="_name in names">
<p>{{_name.username}}</p>
</div>
</div>
To run multiple applications in an HTML document you must manually bootstrap them using angular.bootstrap()
HTML
<!-- Automatic Initialization -->
<div ng-app="myFirstModule">
...
</div>
<!-- Need To Manually Bootstrap All Other Modules -->
<div id="module2">
...
</div>
JS
angular.
bootstrap(document.getElementById("module2"), ['mySecondModule']);
The reason for this is that only one AngularJS application can be automatically bootstrapped per HTML document. The first ng-app found in the document will be used to define the root element to auto-bootstrap as an application.
In other words, while it is technically possible to have several applications per page, only one ng-app directive will be automatically instantiated and initialized by the Angular framework.
You can use angular.bootstrap() directly... the problem is you lose the benefits of directives.
First you need to get a reference to the HTML element in order to bootstrap it, which means your code is now coupled to your HTML.
Secondly the association between the two is not as apparent. With ngApp you can clearly see what HTML is associated with what module and you know where to look for that information. But angular.bootstrap() could be invoked from anywhere in your code.
If you are going to do it at all the best way would be by using a directive. Which is what I did. It's called ngModule. Here is what your code would look like using it:
<!DOCTYPE html>
<html>
<head>
<script src="angular.js"></script>
<script src="angular.ng-modules.js"></script>
<script>
var moduleA = angular.module("MyModuleA", []);
moduleA.controller("MyControllerA", function($scope) {
$scope.name = "Bob A";
});
var moduleB = angular.module("MyModuleB", []);
moduleB.controller("MyControllerB", function($scope) {
$scope.name = "Steve B";
});
</script>
</head>
<body>
<div ng-modules="MyModuleA, MyModuleB">
<h1>Module A, B</h1>
<div ng-controller="MyControllerA">
{{name}}
</div>
<div ng-controller="MyControllerB">
{{name}}
</div>
</div>
<div ng-module="MyModuleB">
<h1>Just Module B</h1>
<div ng-controller="MyControllerB">
{{name}}
</div>
</div>
</body>
</html>
You can get the source code for it at:
http://www.simplygoodcode.com/2014/04/angularjs-getting-around-ngapp-limitations-with-ngmodule/
It's implemented in the same way as ngApp. It simply calls angular.bootstrap() behind the scenes.
In my case I had to wrap the bootstrapping of my second app in angular.element(document).ready for it to work:
angular.element(document).ready(function() {
angular.bootstrap(document.getElementById("app2"), ["app2"]);
});
Here's an example of two applications in one html page and two conrollers in one application :
<div ng-app = "myapp">
<div ng-controller = "C1" id="D1">
<h2>controller 1 in app 1 <span id="titre">{{s1.title}}</span> !</h2>
</div>
<div ng-controller = "C2" id="D2">
<h2>controller 2 in app 1 <span id="titre">{{s2.valeur}}</span> !</h2>
</div>
</div>
<script>
var A1 = angular.module("myapp", [])
A1.controller("C1", function($scope) {
$scope.s1 = {};
$scope.s1.title = "Titre 1";
});
A1.controller("C2", function($scope) {
$scope.s2 = {};
$scope.s2.valeur = "Valeur 2";
});
</script>
<div ng-app="toapp" ng-controller="C1" id="App2">
<br>controller 1 in app 2
<br>First Name: <input type = "text" ng-model = "student.firstName">
<br>Last Name : <input type="text" ng-model="student.lastName">
<br>Hello : {{student.fullName()}}
<br>
</div>
<script>
var A2 = angular.module("toapp", []);
A2.controller("C1", function($scope) {
$scope.student={
firstName:"M",
lastName:"E",
fullName:function(){
var so=$scope.student;
return so.firstName+" "+so.lastName;
}
};
});
angular.bootstrap(document.getElementById("App2"), ['toapp']);
</script>
<style>
#titre{color:red;}
#D1{ background-color:gray; width:50%; height:20%;}
#D2{ background-color:yellow; width:50%; height:20%;}
input{ font-weight: bold; }
</style>
You can merge multiple modules in one rootModule , and assign that module as
ng-app to a superior element ex: body tag.
code ex:
<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<script src="namesController.js"></script>
<script src="myController.js"></script>
<script>var rootApp = angular.module('rootApp', ['myApp1','myApp2'])</script>
<body ng-app="rootApp">
<div ng-app="myApp1" ng-controller="myCtrl" >
First Name: <input type="text" ng-model="firstName"><br>
Last Name: <input type="text" ng-model="lastName"><br>
<br>
Full Name: {{firstName + " " + lastName}}
</div>
<div ng-app="myApp2" ng-controller="namesCtrl">
<ul>
<li ng-bind="first">{{first}}
</li>
</ul>
</div>
</body>
</html>
var shoppingCartModule = angular.module("shoppingCart", [])
shoppingCartModule.controller("ShoppingCartController",
function($scope) {
$scope.items = [{
product_name: "Product 1",

product_name: "Product 2",
price: 20
}, {
product_name: "Product 3",
price: 180
}];
$scope.remove = function(index) {
$scope.items.splice(index, 1);
}
}
);
var namesModule = angular.module("namesList", [])
namesModule.controller("NamesController",
function($scope) {
$scope.names = [{

var namesModule = angular.module("namesList2", [])
namesModule.controller("NamesController",
function($scope) {
$scope.names = [{
username: "Nitin"
}, {
username: "Mukesh"
}];
}
);
angular.element(document).ready(function() {
angular.bootstrap(document.getElementById("App2"), ['namesList']);
angular.bootstrap(document.getElementById("App3"), ['namesList2']);
});

AngularJS API
You can define a Root ng-App and in this ng-App you can define multiple nd-Controler. Like this
<!DOCTYPE html>
<html>
<script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.3.3/angular.min.js"></script>
<style>
table, th , td {

padding: 5px;
}
table tr:nth-child(odd) {
background-color: #f2f2f2;
}
table tr:nth-child(even) {
background-color: #ffffff;
}
</style>
<script>
var mainApp = angular.module("mainApp", []);
mainApp.controller('studentController1', function ($scope) {
$scope.student = {
firstName: "MUKESH",
lastName: "Paswan",
fullName: function () {
var studentObject;
studentObject = $scope.student;
return studentObject.firstName + " " + studentObject.lastName;
}
};
});
mainApp.controller('studentController2', function ($scope) {
$scope.student = {
firstName: "Mahesh",
lastName: "Parashar",
fees: 500,
subjects: [

{ name: 'Hindi', marks: 67 }
],
fullName: function () {
var studentObject;
studentObject = $scope.student;
return studentObject.firstName + " " + studentObject.lastName;
}
};
});
</script>
<body>
<div ng-app = "mainApp">

I have modified your jsfiddle, can make top most module as rootModule for rest of the modules.
Below Modifications updated on your jsfiddle.
Second Module can injected in RootModule.
In Html second defined ng-app placed inside the Root ng-app.
Updated JsFiddle:
http://jsfiddle.net/ep2sQ/1011/
Use angular.bootstrap(element, [modules], [config]) to manually start up AngularJS application (for more information, see the Bootstrap guide).
See the following example:
// root-app
const rootApp = angular.module('root-app', ['app1', 'app2']);
// app1
const app1 = angular.module('app1', []);
app1.controller('main', function($scope) {
$scope.msg = 'App 1';
});
// app2
const app2 = angular.module('app2', []);
app2.controller('main', function($scope) {
$scope.msg = 'App 2';
});
// bootstrap
angular.bootstrap(document.querySelector('#app1'), ['app1']);
angular.bootstrap(document.querySelector('#app2'), ['app2']);

var shoppingCartModule = angular.module("shoppingCart", [])
shoppingCartModule.controller("ShoppingCartController",
function($scope) {
$scope.items = [
{product_name: "Product 1", price: 50},
{product_name: "Product 2", price: 20},
{product_name: "Product 3", price: 180}

This is in the JS file
(function(){
var app = angular.module('myApp', []);
app.controller('appController',[ '$scope', '$http', function($scope, $http){
$http.get('auto_data.json').then(function(quizData){
$scope.myQuestions = quizData.data;
});
}]);
})();
This is the JSON
{
"question" : "Saturn is the ______ planet from the Sun.",
"image" : "images/category/1.jpg",
"answers" : [
{"id" : 0, "text" : "Fourth" },
{"id" : 1, "text" : "Sixth" },
{"id" : 2, "text" : "Second" },
{"id" : 3, "text" : "Eight" }
],
"correct" : 1
}
And this is my HTML
<!DOCTYPE HTML>
<html ng-app="myApp">
<div id="myQuiz" ng-controller="appController">
<div ng-repeat="myQuestion in myQuestions " >
<h2 class="txt" >{{myQuestion.question}}</h2>
<div ng-repeat="answer in myQuestions[$index].answers">
<p>{{answer.text}}</p>
<img ng-src="{{myQuestion.image}}" >
</div>
</div>
</div>
<script src="js/angular.min.js"></script>
<script src="js/quiz_test.js"></script>
</html>
In this situation the image shows up 3 times on the page. How to make the image show up only once?
Move the <img ng-src="{{myQuestion.image}}" > below the the closing </div> under its current position. It's shown multiple times because it's caught up in ng-repeat.
You can either place the image outside the inner ng-repeat, or you can conditionally display it by $index.
<div ng-repeat="myQuestion in myQuestions">
...
<div ng-repeat="answer in myQuestion.answers">
<p>{{answer.text}}</p>
<img ng-src="{{myQuestion.image}}" ng-if="$index == 0"/>
</div>
</div>
