jQuery pitfalls to avoid [closed]

Answer 1

Avoid searching through the entire DOM several times. This is something that really can delay your script.

Bad:

$(".aclass").this();
$(".aclass").that();
...

Good:

$(".aclass").this().that();

Bad:

$("#form .text").this();
$("#form .int").that();
$("#form .choice").method();

Good:

$("#form")
    .find(".text").this().end()
    .find(".int").that().end()
    .find(".choice").method();
