export function button1_click(event, $w) {
 const user = wixUsers.currentUser;
 const userId = user.id;
 // this is the item in the repeater assuming that the button is in the repeater.
    wixData.query("panier") // get the item from the database collection.
        .eq("title", $w("#title").text)
        .find()
        .then((results) => {
 const itemDemandededevis = results.items[0];
            itemDemandededevis.userId = userId; // adding a field of the current user to the database in order to distinguish between other users wishlist. 
            wixData.insert("Demandededevis", itemDemandededevis) // finally, insert it to the wishlish database collection.
                .then(() => {
 let insert = results.items[0]._id; // instead of results.items[0]
                    console.log('Done')
                });
        });
}

@mickael Check out the introduction of the repeater documentation in the section entitled “Retrieve Repeater Item Data When Clicked”. That’s for a case where the element clicked on is inside the repeater item, which appears to be where the button is on your page.
