I am working on a stock application using Spring Boot. I have stock data from external API which looks like this:
{{stock.dates}} = [2017-05-04, 2017-05-03, 2017-05-02, 2017-05-01,
2017-04-28, 2017-04-27, 2017-04-26, 2017-04-25, 2017-04-24, 2017-04-21]
{{stock.stockValues}} = [150.85, 151.8, 152.78, 152.46, 150.25, 147.7,
146.56, 146.49, 145.47, 143.68]
My index.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8"/>
<title>Stock app</title>
<script>
<!-- Many scripts here-->

My controller.js:
(function(angular) {
'use strict';
var App = angular.module('App');
App.controller('StockController', [ '$scope', '$http', '$routeParams',
'$rootScope', function($scope, $http, $routeParams, $rootScope) {
$scope.init = function() {
if ($rootScope.stockID !== undefined) {
$scope.getStockData($rootScope.stockID);
return;
} else if ($routeParams.stockID !== undefined) {
$rootScope.stockID = $routeParams.stockID;
} else {
$rootScope.stockID = 'FB';
}
$scope.getStockData($rootScope.stockID);
};
$scope.getStockData = function(stockID) {
$scope.loading = true;
$scope.content = false;
$http.get('/stock', {
params : {
stockID : encodeURI(stockID)
}
}).then(function(response) {
$scope.showError = false;
$scope.stock = response.data;
$scope.stockAvailable = true;
}, function(response) {
$scope.showError = true;
}).finally(function() {
// called no matter success or failure
$scope.loading = false;
$scope.content = true;
});
};
$scope.init();
} ]);
})(window.angular);
Now what I need to do is to create a Google Chart using this data (dates vs stock values)
How can I do it?
Also, when I tried to draw a static example chart from Google Charts Tutorial I could only do it in my index.html, when I put the same definition in stock.html, the chart didn't work, do you have any idea why?

Hi I am new to Angularjs. I am learning how to share data between two controllers using dataservice. Looking at the tutorial I made my own program but it is not working. Can anyone suggest what I am doing wrong here?
<!DOCTYPE html>
<html>
<head>
<title>AngularJS Services</title>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0-beta.5/angular.min.js"></script>
</head>
<body>
<div ng-app="dataServiceApp">
<div ng-controller="ChildCtrl">
<h2>First controller</h2>
<button>+</button>{{Holder.value}}
</div>
<div ng-controller="ChildCtrl2">
<h2>Second controller</h2>
<button>+</button>{{Holder.value}}
</div>
</div>
<script>
var myapp = angular.module("dataServiceApp",[]);
myapp.factory('Holder', function() {
return {
value: 0
};
});
myapp.controller('ChildCtrl', function($scope, Holder) {
$scope.Holder = Holder;
$scope.increment = function() {
$scope.Holder.value++;
};
});
myapp.controller('ChildCtrl2', function($scope, Holder) {
$scope.Holder = Holder;
$scope.increment = function() {
$scope.Holder.value++;
};
});
</script>
</body>
</html>
You have forgotten to register onclick listeners to the buttons:
<button ng-click="increment()">+</button>{{Holder.value}}
Hope this helps. Complete working example below:
<!DOCTYPE html>
<html>
<head>
<title>AngularJS Services</title>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0-beta.5/angular.min.js"></script>
</head>
<body>
<div ng-app="dataServiceApp">
<div ng-controller="ChildCtrl">
<h2>First controller</h2>
<button ng-click="increment()">+</button>{{Holder.value}}
</div>
<div ng-controller="ChildCtrl2">
<h2>Second controller</h2>
<button ng-click="increment()">+</button>{{Holder.value}}
</div>
</div>
<script>
var myapp = angular.module("dataServiceApp",[]);
myapp.factory('Holder', function() {
return {
value: 0
};
});
myapp.controller('ChildCtrl', function($scope, Holder) {
$scope.Holder = Holder;
$scope.increment = function() {
$scope.Holder.value++;
};
});
myapp.controller('ChildCtrl2', function($scope, Holder) {
$scope.Holder = Holder;
$scope.increment = function() {
$scope.Holder.value++;
};
});
</script>
</body>
</html>
p.s. I also fully agree with JB Nizet's comment: check whether you really need to learn AngularJS instead of Angular 2-7/VueJS/React.
Please find my my controller javascript file below -
angular.module('myApp', []);
angular.module('myApp').factory('myFactory', function () {
var myFactory = {};
myFactory.list = [];
myFactory.add = function (message) {
myFactory.list.push({ id: myFactory.list.length, text: message });
//return myFactory;
};
return myFactory;
});
angular.module('myApp').controller('Controller1', function (myFactory) {
var myVar = this;
myVar.myList = myFactory.List;
});
angular.module('myApp').controller('Controller2', function (myFactory) {
var myVar = this;
myVar.newMessage = 'Hello World!';
myVar.addMessage = function (message) {
myFactory.add(message);
myVar.newMessage = '';
};
});
And also my HTML file below -
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
</head>
<body ng-app="myApp">
<div>
<h1>Services</h1>
<div' ng-controller="Controller1">
<p ng-repeat="m in myList">{{ m.id }}: {{ m.text }}</p>
</div'>
</div>
<div ng-controller="Controller2 as post">
<form ng-submit="post.addMessage(post.newMessage)">
<input type="text" ng-model="post.newMessage">
<button type="submit"
ng-click="post.addMessage(post.newMessage)">
Add Message
</button>
</form>
</div>
</body>
</html>
<script src="Scripts/angular.min.js"></script>
<script src="Scripts/bootstrap.min.js"></script>
<script src="Scripts/angular.js"></script>
I can't see the data returning by the 'Controller1'
When I run the code I can't see the result which is coming from Controller1, which means the list is not binding with the ng-controller in .html page
Please tell me where I am wrong.
You are not referencing your list properly:
<p ng-repeat="m in myList">{{ m.id }}: {{ m.text }}</p>
If you are going to use myVar to store your list, you should use Controller as syntax so that your template has a reference to the variable:
<div ng-controller="Controller1 as myVar">
<p ng-repeat="m in myVar.myList">{{ m.id }}: {{ m.text }}</p>
</div>
I have the following code:
Trips.cshtml:
#section Scripts{
<script src="~/lib/angular/angular.min.js"></script>
<script src="~/js/app-trips.js"></script>
<script src="~/js/tripsController.js"></script>
}
<div class="row" ng-app="app-trips">
<div >{{"Two plus two : " + (2+2)}}</div>
<div ng-controller="tripsController as vm" class="col-md-6 col-md-offset-3">
{{ vm.name }}
</div>
</div>
app-trips.js:
(function () {
"use strict";
angular.module("app-trips", []);
})();
tripsController.js:
(function () {
"use strict";
angular.module("app-trips")
.controller("tripsController", tripsController);
function tripsController() {
var vm = this;
vm.name = "jaka";
}
})();
In my .cshtml I get "2+2" = 4 shown in angular, but I don't get my vm.name called. Does anyone know what might be the problem?
You have not closed the div,
<div class="row" ng-app="app-trips">
<div >{{"Two plus two : " + (2+2)}}</div>
<div ng-controller="tripsController as vm" class="col-md-6 col-md-offset-3">
{{ vm.name }}
</div>
</div>
DEMO
angular.module("app-trips", []).controller("tripsController", tripsController);
function tripsController() {
var vm = this;
vm.name = "jaka";
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div class="row" ng-app="app-trips">

I have been having this issue with Controllers in Angular. I looked it up as much as possible, but I could not resolve the issue.
I am trying to implement a simple controller, but for the life of me, I cannot get the binding to work. It's not displaying my data. For example when I say, {{ test }}, I get just that, not the "Hello World!" string.
var app = angular.module('App', []);
app.controller('Hi', function($scope){
$scope.hello = "hello!";
});
app.controller('todoCtrl', ['$scope', '$http', function($scope, $http) {
$scope.test = "Hello World!";
$scope.formData = "";
$http.get('/api/todos')
.success(function(data) {
$scope.todos = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
$scope.createTodo = function() {
$http.post('/api/todos', $scope.formData)
.success(function(data) {
$scope.formData.text = "";
$scope.todos = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
};
$scope.deleteTodo = function(id) {
$http.delete('/api/todos/' + id)
.success(function(data) {
$scope.todos = data;
console.log(data);
})
.error(function(data) {
console.log('Error: ' + data);
});
};
}]);

I just executed your code while placing angular file link above the script tag, so that AngularJs is loaded before your script can call angular modules.
I think you're putting angular after your script which is why you are running into this issue. Your code works just fine. I tested it.
Put it like this
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.7/angular.min.js"></script>
<script src="script.js"></script>
Here script.js will be your controller script.
Working fiddle
I want to add data at the time of onclick event. Need to load image at the time of onclick event, after a small time interval add data. But my image is continuously loading. Any body give any suggestion.
My code is:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js" type="text/javascript"></script>

function ContactController($scope) {
$scope.contacts = [];
$scope.items = [ ];
$scope.add = function() {
setTimeout(function() {
$scope.$apply(function() {
$scope.items[0].lateLoader = ' xxxx ';
});
}, 1000);
$scope.count=$scope.count+1;
$scope.contacts.push($scope.newcontact);
$scope.newcontact = "";
}
}
</script>
</head>
<body >
<div ng-app="" ng-controller="ContactController">
<p>{{items.lateLoader}}
<i ng-hide="items.lateLoader"><img src="Filling broken ring.gif"></i>
</p>
{{ contacts.length }}
Content:<input type="text" ng-model="newcontact" />
<button ng-click="add()">Add</button>
<ul style="list-style-type: none;">
<li ng-repeat="contact in contacts"> <input name="" type="checkbox" value="">{{ contact }}</li>
</ul>
</div>
</body>
</html>
In your example I found a lot of mistakes. The HTML tag is not defined at the top, wrong use of angularJs and Angular module is not created properly etc.
I fixed all the mistakes. I hope it can help you.
