I don't really understand why you would like to use the element id, but here you go:

You need to make an xhr request with jquery as you already use it and send it to your nodejs server. Then handling the request with an express route as a body value and do whatever you want.

Ajax request:

var data = {};
data.id = myid;
$.ajax({
 type: "POST",
 url: url,
 data: data,
 success: success,
 dataType: dataType
});

And your express route

app.post('/myroutename', function(req,res,next,) {
    var id = req.body.id;
    // then do whatever you want with your id
});

But i suggest you to read more about Express and JQuery post
