Enhancing Your Website Listings with Firebase: A Step-by-Step Guide to Updating

I am currently working on an admin panel for a website, utilizing Firebase as the backend database. I have successfully implemented the listings display feature, however, I'm facing an issue where clicking on a specific listing should change its status from 'pending' to 'accept', but it's not happening as expected. I'm struggling to identify the mistake in my code. Any suggestions or insights would be greatly appreciated. Below is the snippet of my pl.js file along with a screenshot of the database.

pl.js

 var firebaseheadingRef = firebase.database().ref().child("user");


    firebaseheadingRef.on('child_added',datasnapshot=>{

       var title= datasnapshot.child("listing").child("title").val();
       var userid= datasnapshot.child("username").val();
       var type= datasnapshot.child("listing").child("title").val();
       var publisheddate= datasnapshot.child("listing").child("publish").val();
       var expirydate= datasnapshot.child("listing").child("expire").val();

       $("#tablebody").append("<tr><td>"+title+"</td><td>"+userid+"</td><td>"+type+"</td><td>"+publisheddate+"</td><td><button type=button id=accept onclick=accept()>Accept</button><button type=button>Reject</button></td></tr>");
      });


    function accept()
    {
      firebaseheadingRef.on('child_changed',datasnapshot=>{
        datasnapshot.child("listing").child("status").update({"status":"accept"});
        setCommentValues(postElement, data.key, data.val().text, data.val().author);

      });
    }

This image displays the listing where clicking on the accept button triggers the status update process.

If you want to make changes to your code, there are two key areas that need attention:

Firstly, when generating the table in your code, be sure to include the node ID in the function call. This can be obtained using the key property of the DataSnapshot.

.....
$("#tablebody").append("<tr><td>"+title+"</td><td>"+userid+"</td><td>"+type+"</td><td>"+publisheddate+"</td><td><button type=button id=accept onclick=accept('" + datasnapshot.key + "')>Accept</button><button type=button>Reject</button></td></tr>");
...

Secondly, ensure that your accept() function is designed to update the database value using the set() method, as shown below:

function accept(userId) {
  var nodeRef = firebase.database().ref("/user/" + userId + "/listing/status");
  return nodeRef.set('accept');
}
