How to get value from JSON in Angular Controller?

Question

Angular

Good afternoon! There is a question that interests me very much and I can not figure it out in any way. I know how to get JSON array value into HTML file. But for example, I need to get this value directly in the controller, let's imagine a number of posts and they have this id and I want to create a delete button for each post and how can I get this id in the Controller right away?
Is there such an example?

"id": "802",
      "component": "blogs",
      "type": "new_blog_post",
      "user": {
        "id": "1",
        "username": "admin",
        "mail": "[email protected]",
        "display_name": "mr. Whale",
        "avatar_thumb": "avatars/1/57f4791714aa4-bpfull.jpg",
        "is_following": 0
      }

Answer 1

Let's say you have posts displayed there using ngRepeat :
Add a delete button, hang ngClick on it, where you pass a function from the controller with an argument in the form of an ID.
For example like this:

<span ng-click="vm.removeItem(post.id)">Delete</span>
