Getting the id of the database table from dynamic page to update the record.

Hello, I am trying to get the id of the database table row to update the record. I have created a dynamic page which is connected to the database. Everything is working fine but now I want the id of that specific record shown on the dynamic page so that if the user clicks a button on that page the record’s specific field updates. So is there any way to get the id through the javascript or something?

Regards.

getCurrentItem gives you the record and the _id gives you the id.
