JavaScript

You need to send 2 posts - one to the group, the second - to your wall. How to display 2 confirmations?
now I specify wall.post 2 times in a row and only confirmation of the latter is shown.

Answer 1

First, you call one request to create a record, after its execution there will be a callback. When you receive a callback, immediately send a second request.
Something like this:

VK.api("wall.post", {"message": "Этот пост мне на стену!"}, function (data1) {
  VK.api("wall.post", {"message": "А этот пост в группу!", "owner_id": -123456}, function (data2) {
    alert("Вы отправили 2 записи!")
  });
});
