Check checkbox checked property using jQuery

Use this code for check box in jquery

if ($('#facebook').is(':checked')) {

    $("#fb").show();
}else {
    $("#fb").hide();
}

You can shorten this using ternary, some might say it's a bit

 less readable, but that's how I would do it:

$('#facebook').is(':checked') ? $("#fb").show() : $("#fb").hide();
