I solved this problem as i added angular.module but i want to know that is there any other solution for this i somebody know please help me......
<html ng-app="myapp">
..
<body>
<div ng-controller="MyFirstController">
<div ng-repeat="album in albums | filter:searchFor | orderBy:date " >
...
</div>
...
</div>
<script type="text/javascript">
var app = angular.module("myapp");
app.controller('MyFirstController', function MyFirstController($scope){
$scope.albums =[{ name: 'abc', title: 'Weekend' }];
});
</script>
</body>
This can help you
var myApp = angular.module('myApp',[]);
//myApp.directive('myDirective', function() {});
//myApp.factory('myService', function() {});
function MyCtrl($scope) {
$scope.albums =[{ name: 'abc', title: 'Weekend' },{ name: 'abcd', title: 'Weekend' }];
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
<div ng-repeat="album in albums | filter:searchFor | orderBy:date " >
{{album.name +" "+ album.title}}
</div>
</div>
Try this:-
Controller
var myApp = angular.module("myApp")
.controller('MyFirstController', function ($scope) {
// write your business logic here
$scope.albums =[{
name: 'abc',
title: 'Weekend'
}];
})
HTML
<html ng-app="myApp">
<body>
<div ng-controller="MyFirstController">
<div ng-repeat="album in albums | filter:searchFor | orderBy:date " >
</div>
</div>
</body>
If you are using ng-controller, ng-app or other directives, controllers then it is must to write module.
module is a container act for controllers, directives, services, etc
so if you want to add or Inject these then use that container angulr.module.

I have a ng-repeat on a div which shows value from an array in the controller. The div is commented when I do the inspect element in the browser. I have an outer div with the ng-controller on it.
This is the html file:
<!DOCTYPE html>
<html ng-app="myapp">
<head>
<title></title>
<script type="text/javascript" src="../js/angular.js"></script>
<script type="text/javascript" src="../js/angular-route.js"></script>
<script type="text/javascript" src="../js/controller.js"></script>
<!-- <base href="localhost:5000/"/> -->
<base href="/"/>
</head>
<body>
<div ng-controller="firstController">
First name:<input type="text" ng-model="firstName"><br>
Last name:<input type="" ng-model="lastName"><br>
<input type="button" ng-click="loadView()" value="submit" name="">
<p>{{firstName}}</p>
<div ng-repeat="data in array">
{{data.name}}
</div>
</div>
</body>
</html>
This is the controller:
var app = angular.module('myapp',['ngRoute']);
// var app = angular.module('myapp',[]);
app.config(function($routeProvider,$locationProvider){
$routeProvider.when('/index',{
templateUrl:'./view/index.html',
controller:'firstController'
})
.when('/second/:firstName/:lastName',{
templateUrl:'./view/second.html',
controller:'secondController'
})
.otherwise({redirectTo:'/index'})
$locationProvider.html5Mode(true);
})
app.controller('firstController',function($scope,$location){
$scope.firstName = "";
$scope.lastName="";
$scope.loadView = function(){
$location.path('/second/'+$scope.firstName+"/"+$scope.lastName);
}
var arrays = [
{name:ab}, {name:ba}, {name:ac}, {name:ca}
];
$scope.array = arrays;
})
.controller('secondController',function($scope,$routeParams){
$scope.firstName = $routeParams.firstName;
$scope.lastName = $routeParams.lastName;
})
And also, when I try to navigate to second.html on button click which calls the loadView() in the controller, I see the url in the address bar has changed but it still shows the content of the first html(index.html).
The values for the array should be in single quotes unless they are variables. So instead of {name:ab} just do {name:'ab'}
Check out the snippet
var app = angular.module('myapp', []);
// var app = angular.module('myapp',[]);
app.controller('firstController', function($scope, $location) {
$scope.firstName = "";
$scope.lastName = "";
$scope.loadView = function() {
$location.path('/second/' + $scope.firstName + "/" + $scope.lastName);
}
var arrays = [{
name: 'ab'
}, {
name: 'ba'
}, {
name: 'ac'
}, {
name: 'ca'
}];
$scope.array = arrays;
})
.controller('secondController', function($scope, $routeParams) {
$scope.firstName = $routeParams.firstName;
$scope.lastName = $routeParams.lastName;
})
<!DOCTYPE html>
<html ng-app="myapp">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
</head>
<body>
<div ng-controller="firstController">
First name:
<input type="text" ng-model="firstName">
<br>Last name:
<input type="" ng-model="lastName">
<br>
<input type="button" ng-click="loadView()" value="submit" name="">
<p>{{firstName}}</p>
<div ng-repeat="data in array">
{{data.name}}
</div>
</div>
</body>
</html>
The div gets commented when the object is empty.
Make sure that your $scope.object has the data that you want.
I'm trying to output the name "Sam" on the screen in a ng-show using indexOf, but nothing ever appears. Any help is appreciated.
html
<head></head>
<body>
<div ng-controller="ArrayController">
<div ng-repeat="product in products">
<div ng-show="product.name.indexOf('Sam') == 2">
</div>
</div>
</div>
<script src="bower_components/angular/angular.js"></script>
<script src="app.js"></script>
</body>
</html>
angular
var app = angular.module('myApp', []);
app.controller('ArrayController', ['$scope', function($scope){
$scope.products = [
{
name: 'Joe'
},
{
name: 'Bill'
},
{
name: 'Sam'
}
];
}]);
Possible solution using ng-if instead of ng-show
<body ng-app="myApp">
<div ng-controller="ArrayController">
<div ng-repeat="product in products">
<div ng-if="product.name.indexOf('Sam') > -1">{{product.name}}
</div>
</div>
</div>
</body>
var app = angular.module('myApp', []);
app.controller('ArrayController', ['$scope', function($scope){
$scope.products = [
{
name: 'Joe'
},
{
name: 'Bill'
},
{
name: 'Sam'
}
];
}]);
<div ng-show="product.name.indexOf('Sam') == 2"></div>
This will show the div if product.name contains the string "Sam" starting at its third character (i.e. "xxSam"). That probably isn't what you want.
The div is empty, so will not be visible to the user even if the ng-show is truthy. That, too, is probably not what you want.
I'm pretty sure what you do want is this:
<div>{{product.name}}</div>
I was writing a code in html5 and angular js. I am encountering a problem in passing parameters with space. Here is my code :
angular.module('MyApp', [])
controller('MyCtrl', function($scope) {
$scope.validate = function(description,code) {
alert(description,code);
}
});
<!DOCTYPE html>
<html>
<body ng-app="MyApp">
<div ng-repeat="x in allItem.items" class="col-75" ng-controller="MyCtrl">
<a href="#" ng-click="validate({{x.itemDesc}},{{x.itemCode}})">
<div class="card item center">{{x.itemName}}
</div></a>
</div>
</body>
</html>
The JSON format is like this
Json contains
allItem
{
items
{
itemName: "egg",
itemDesc: "Egg is very delicious",
itemCode: "EGG"
}
{
itemName: "Tomato",
itemDescr: "Tomato's skin contains vitamins",
itemCode: "TMT"
}
}
I am not able to pass the parameters. I don't know how to pass the text that contains spaces and quotes('). Can anyone help me
Your Json needs to be an array, skip the href="#" and you do not need to bind within ng-click. The code below is fully functioning and running.
angular.module('MyApp', [])
.controller('MyCtrl', function($scope) {
$scope.allItem =
{
items:[
{
itemName: "egg",
itemDesc: "Egg is very delicious",
itemCode: "EGG"
},
{
itemName: "Tomato",
itemDesc: "Tomato's skin contains vitamins",
itemCode: "TMT"
}
]
};
$scope.validate = function(description, code) {
console.log(description,'-', code);
};
});

At start i want to say im new in angular. Lets say my page look like this:
index.html:
<body ng-app="application">
<div class="container">
<div class="row">
<div class="col-sm-3 sideBar" ng-controller="NavController">
<input ng-model"search">
</div>
<div class="col-sm-9 content" ng-controller="ContentController">
<div ng-repeat="meet in meets | filter:search">
{{ meet.someData }}
</div>
</div>
</div>
</div>
</body>
And how can i make that input in NavController could filter data from ContentController? I want to do this in two controllers.
I'm not sure why you want to do this in two controllers, but it will be considerably more difficult. The Search functionality acts on the data in the content controller. I am guessing that your layout is driving your controller design.
There are numerous posts here that discuss techniques for this. This one: Share data between AngularJS controllers is well-regarded.
Actually you can just do that in a single controller.
var app = angular.module('angularjs-starter', []);
app.controller('MainCtrl', function($scope) {
$scope.name = [{
"id":1
},{
"id":2
},{
"id":3
}]
});
<!DOCTYPE html>
<html ng-app="angularjs-starter">
<head lang="en">
<meta charset="utf-8">
<title>Custom Plunker</title>
<script src="//code.angularjs.org/1.1.1/angular.js"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl"><input ng-model='find' />
<div ng-repeat="x in name | filter : find">
{{x.id}}
</div>
</body>
</html>
For understanding, i used numbers as data. :) Hope it helps you
You can have a parent controller over the other two controllers. If you use the controllerAs method you can have controllers inside each other, see Angular Style Guide for helpful information about controllers and controllerAs.
You could write it like that and bind the search model to the ParentController.
Edit: I added another solution that I think is better
var app = angular.module('app', []);
app.controller('ParentController', function() {
this.search = 'p'; //set default just for fun
});
app.controller('NavController', function() {
//nav stuff
});
app.controller('ContentController', function() {
this.meets = [{
data: 'hi'
}, {
data: 'potato'
}, {
data: 'help me'
}, {
data: 'pie'
}];
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="app">
<div class="container" ng-controller="ParentController as parentVm">
<div class="row">
<div class="col-sm-3 sideBar" ng-controller="NavController as navVm">
<input ng-model="parentVm.search">
</div>
<div class="col-sm-9 content" ng-controller="ContentController as contentVm">
<div ng-repeat="meet in contentVm.meets | filter:parentVm.search">
{{ meet.data }}
</div>
</div>
</div>
</div>
</body>
I stepped away from this for a bit and thought of another idea that doesn't involve using another controller. Here you are using a factory instead to communicate between the controllers. You have to share an object so that when you change the search.term in the input it will change for every reference.
var app = angular.module('app', []);
app.factory('Searcher', function() {
return {
search: {
term: 'p'
}
};
});
app.controller('NavController', function(Searcher) {
//nav stuff
this.search = Searcher.search;
});
app.controller('ContentController', function(Searcher) {
this.search = Searcher.search;
this.meets = [{
data: 'hi'
}, {
data: 'potato'
}, {
data: 'help me'
}, {
data: 'pie'
}];
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="app">
<div class="container">
<div class="row">
<div class="col-sm-3 sideBar" ng-controller="NavController as navVm">
<input ng-model="navVm.search.term">
</div>
<div class="col-sm-9 content" ng-controller="ContentController as contentVm">
<div ng-repeat="meet in contentVm.meets | filter:contentVm.search.term">
{{ meet.data }}
</div>
</div>
</div>
</div>

I am a beginner to Angularjs. I am practicing by watching videos. I tried a program.
<!doctype html>
<html ng-app="store">
<head>
<meta charset="UTF-8">
<title>Example</title>
</head>
<body >
<div ng-Controller="StoreController as store">
<h1>{{store.product.name}}</h1>
<h2>{{store.product.price}}</h2>
<p>{{store.product.lastname}}</p>
</div>
<script type="javascript" src="lib/angular.min.js"></script>
<script src="lib/app.js" type="javascript"></script>
</body>
</html>
saved as 'index.html' &
(function(){
var app= angular.module('store',[]);
app.controller('StoreController', function()
{this.product = gem;}
);
var gem = {
name : 'Deco',
price : 2.5,
lastname : 'ANIL KUMAR',
}
})();
Saved as app.js
but it is not showing data only showing
{{store.product.name}}
{{store.product.price}}
{{store.product.lastname}}
Check your console log for errors. I see at least one error, the gem variable is lost because controller is called in future. Declare gem inside controller.
(function () {
var app = angular.module('store', []);
app.controller('StoreController', function () {
var gem = {
name: 'Deco',
price: 2.5,
lastname: 'ANIL KUMAR',
}
this.product = gem;
});
})();
You have to declare the variable 'gym' as a scope variable inside the controller. Please check this fiddle
http://jsfiddle.net/ashraffayad/pdbrds7m/
var store = angular.module('myApp',[]);
store.controller('StoreController', ['$scope', function (scope) {
scope.gym = {
name: 'Deco',
price: 2.5,
lastname: 'ANIL KUMAR'}
}]);
<div ng-app="myApp" ng-Controller="StoreController">
<h1>{{gym.name}}</h1>
<h2>{{gym.price}}</h2>
<p>{{gym.lastname}}</p>
</div>
Thank-you Both of you. Both the codes are correct.
After Debugging at every step finally i found the mistake.
<div ng-Controller="StoreController as store">
<input type="text" ng-model="name"></input>
<h1>{{store.product.name}}</h1>
<h2>{{store.product.price}}</h2>
<p>{{store.product.lastname}}</p>
</div>
<script src="lib/angular.min.js"></script>
<script src="lib/app.js"></script>
&
(function(){
var app= angular.module('store',[]);
app.controller('StoreController', function()
{this.product = gem;}
);
var gem = {
name : 'Deco',
price : 2.5,
lastname : 'ANIL KUMAR',
}
})();
This is working now.
