I have written scripts to create a whiteboard using canvas inside the template page of AngularJS. Now I need to assign the values of the points[] variable to an AngularJS scope variable.
<script>
var points = [];
</script>
How can I access the points in an AngularJS controller?
scope.points = points;
To access the variable, you can utilize the $window service in this way:
var points = ['1','2'];
var app = angular.module('myapp', []);
app.controller('MainCtrl', ['$scope', '$window', function($scope, $window) {
$scope.point= $window.points ;
}]);
To see a working example, check out this plunker: http://plnkr.co/edit/FzybyOZKiLvHuaMaYCuJ?p=preview
To access it in your controller, you can refer to it in the global scope.
Check out this plunkr:
http://plnkr.co/edit/G8RQKe6tK48mWXpsl9ov?p=preview
<script>
var points = [];
</script>
<body ng-controller="MainCtrl">
<p>Points: {{data}}</p>
</body>
</html>
Additionally, in the app.js file:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.data = points;
});
