I am trying to convert strings to AngularJS Service method calls in a controller. For example, I would like to convert the string "Contact.send(email)" to call an existing service method. I thought to use:

window["Contact"]["send"](email);

as in this thread - How to execute a JavaScript function when I have its name as a string - but it says that the Contact service is undefined, despite being injected into the controller.

• javascript
• angularjs
• angularjs-scope
• angularjs-service

• 1 Have you tried something like eval("contact.send(email)");? – AdityaParab Commented Jul 18, 2014 at 4:49
• I was trying to avoid using eval, if at all possible. – user2715324 Commented Jul 18, 2014 at 4:56

• We need more code to go on. Why are you trying to reference Contact on window if it was injected into your controller? Post your controller and the service returning Contact please. – ChevCast Commented Jul 18, 2014 at 5:01

You need to use $injector to get a service from a string:

$injector.get('Contact')['send'](email);

You can use the $scope.$eval method to evaluate an expression on the current $scope context.

$scope.$eval("Contact.send(email)");

but you need to make sure that the Contact object is available on the $scope object, else it would not work. See scope documentation for this https://code.angularjs/1.2.15/docs/api/ng/type/$rootScope.Scope
