if you just trying to hide element by id you can use onclick

<button onclick="this.style.display = 'none'">Hide Me</button>

or you can pass the id to javascript function

    <button id="detail_<?php echo $row['id'] ?>" onclick="hideElement(this.id)">Hide Me</button>
    <script>
    function hideElement(id){
    document.getElementById(id).style.visibility = "visible";
    }
   </script>

i’m confused on how to write this correctly
so the ID is distinquished by numbers. example in html:

id ="detail_$row["id"]"

this is what i’m trying to get in my script

document.getElementById("detail_<?php echo $row["id"] ?>").style.visibility = "visible";
