A scope provides a separation between View and its Model. Every application has a $rootScope provided by AngularJS and every other scope is its child scope.
Using $Rootscope
Using rootscope we can set the value in one controller and read it from the other controller.
The following is the sample code snippet,
code
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.min.js">
</script>
<script>
var myApp = angular.module('myApp', []);
function controllerOne($scope, $rootScope)
{
$rootScope.name = 'From Rootscope set in controllerOne';
}
function controllerTwo($scope, $rootScope)
{
$scope.name2 = $rootScope.name;
}
</script>
</head>
<body>
<div style="border: 5px solid gray; width: 300px;">
<div ng-controller="controllerOne">
Setting the rootscope in controllerOne
</div>
<div ng-controller="controllerTwo">
Hello, {{name2}}!
</div>
<br />
</div>
</body>
</html>
