由 安稳与你 提交于 2019-12-11 03:37:02

Accessing parent Controllers scope within a directive that uses ControllerAs and scope:true

由 拥有回忆 提交于 2019-12-11 03:25:46
问题 I'm trying to use ControllerAs in a directive with no $scope injection, using this instead, and I'm struggling when scope:true When I use an isolated scope everything works fine because I can use bindToController: true , but in this case I'm missing something and I don´t know what.

This can be easily done using $scope injection in both controllers, but when I

由 狂风中的少年 提交于 2019-12-11 02:48:30

My question is does polluting the $scope object affect performance? Is it a good idea to clean this up so only values and methods needed for the view are contained in the $scope object? 回答1: Yes,
