jQuery - how can I find the element with a certain id?

Question

I have a table and each of its td has a unique id that corresponds to some time intervals (0800 til 0830... 083

Answer 1

I don't know if this solves your problem but instead of:

$("#tbIntervalos").find("td").attr("id", horaInicial);

you can just do:

$("#tbIntervalos td#" + horaInicial);
