Question

I was wondering if I really have to write:

if (status) {
    $('#status-image-' + id).fadeIn();
} else {
    $('#status-image-' + id).fadeOut();
}

or there is a function to which I can provide my boolean status, something like:

$('#status-image-' + id).fade(status);

I’ve seen fadeToggle, but it doesn’t accept a boolean status parameter.

No, there is not, but you can make one like that:

jQuery.fn.fadeInOrOut = function(status){
    return status ? this.fadeIn() : this.fadeOut();
}

and then call it like that (see this jsfiddle for a proof):

$('#status-image-' + id).fadeInOrOut(status);

Is it what you wanted?
