AJAX in 1C-Bitrix. How to get detailed news data?

Question

1C-Bitrix

In the news, each news has a button for detailed viewing. When you click on the button, a window opens with detailed information. What is the correct way to get detailed data using AJAX? In my understanding, I have to send a request to the detailed page when the button is clicked, get the data and substitute it in the window that opens.

Answer 1

send a request to the detailed page when clicking on the button, get the data and substitute it in the window that opens

As an option, if the display of the detailed and in the pop-up window is the same.
Another possible option is to create a separate file (for example: /local/templates/.default/components/bitrix/news/news.detail/.default/ajax.php), pass the id to it and connect the news.detail component in the file, with the desired template and parameters, and pass your id there. Further, after receiving the ajax results, substitute them in the right place.
The second option is more flexible IMHO.
In any case, you need to proceed from the features of the problem.
