The beauty of JQuery...

Query by element tag name

    $("div")

Query by element id

    $("#myid")

Query by css class name

    $(".css-whatever")

Query by input type

    $("input:checkbox")

Query by a set of element ids

    $("#myid1,#myid2,#myid3")

Query by input type but exclude the one with 'whatever' id

    $("input:checkbox:not(#whatever)")
