在JS中添加表中的新行，如何包含变量？

Question

I know I'm making a stupid mistake... but I started using ajax just an hour ago. I have a problem with variables in JS.

When i write +'id_komputery'+ then js return error : "Uncaught SyntaxError: missing ) after argument list". The same with id='id_komputery'

    $.ajax({
    url:'add.php',
    method:'POST',
    data:{
        producent_new:'producent_new',
        nazwa_new:'nazwa_new'
    },
    success:function()
    {
        var id_komputery = '<?= $id_komputery ?>';
        console.log(id_komputery);
        $("#main_table > tbody").append('<tr id='id_komputery' ><td width="50" align="center"><input type="checkbox" name="komp_id[]" class="delete_komputery" value='id_komputery' /></td><td width="50" align="center">+'id_komputery'+</td></tr>');
    }
});

Replace this line:

$("#main_table > tbody").append('<tr id='id_komputery' ><td width="50" align="center"><input type="checkbox" name="komp_id[]" class="delete_komputery" value='id_komputery' /></td><td width="50" align="center">+'id_komputery'+</td></tr>');

with this one:

$("#main_table > tbody").append('<tr id="' + id_komputery + '"><td width="50" align="center"><input type="checkbox" name="komp_id[]" class="delete_komputery" value='id_komputery' /></td><td width="50" align="center">'+id_komputery+'</td></tr>');
