angular.js - How does angular get html content and store it somewhere else?

Question

Inside the red box is a loop of content, which is implemented using $http and ng-repeat.
My requirement is that you can click "View More" How to get the content in the blue box and assign it to a pop-up layer?
I don’t quite understand the injection service. I hope you can give me some brief code and be more detailed. Thank you!

Answer 1

What does the elastic layer here refer to?
If the pop-up layer and the blue box are in the same controller, save the object in the controller's scope and bind the object directly to the pop-up layer.
