You have a problem in assigning a variable:

var first_tr_id = tr_id_1

it should be inside quote

var first_tr_id = "tr_id_1"

Also, to get all the IDs, you can use the following code:

$("table tr").each(function(index) {
   alert($(this).id());
}

You code lacks the jQuery $

var nextId = $('#'+first_tr_id ).next("tr").attr("id");

Also an id is a string, so you should set your variable like so :

var first_tr_id = 'tr_id_1';    // id of first tr
