Creating a rootscope variable within an .ASPX file

I'm currently facing a challenge of defining an AngularJS rootscope variable within an .ASPX file for utilization in a TypeScript file. However, I'm not entirely sure on the best approach to achieve this. I am willing to explore any viable methods to establish a value in an .ASPX file and effectively leverage it in my TypeScript code. Please feel free to suggest alternative solutions that could assist me in tackling this issue.

Answer №1

If you want to inform TypeScript about the existence of a certain property, you have the option to extend the rootScope interface:

interface extendedRootScope extends ng.IRootScopeService {
    myProp: number;
}

Then, when injecting $rootScope in your controller, specify it as your new interface:

export class MyController {
    constructor(private $rootScope: extendedRootScope) { }

    someMethod() {
        // Access this.$rootScope.myProp
    }
}

If you need to interact with $rootScope outside of the Angular context (such as in your ASPX page) to include the property, you can use the following approach:

<script>
    var injector = angular.element('[ng-app]').injector();
    var $rootScope = injector.get('$rootScope');

    $rootScope.myProp = 1;
</script>

This assumes that you are utilizing ng-app for initializing your Angular application.

Likewise, you could generate an Angular service dynamically within a script tag, inject $rootScope into that service, and append properties to it.
