jQuery loop through possible elements to see if they exist?

I have some jQuery like this:

    $('#mydiv1').css('color', 'red');
    $('#mydiv2').css('color', 'blue');
    $('#mydiv3').css('color', 'green');
    $('#mydiv4').css('color', 'orange');
    $('#mydiv5').css('color', 'purple');

Open in new window

I think it should be this, so it only acts if the element exists:

    if ($('#mydiv1')) {.css('color', 'red')}
    if ($('#mydiv2')) {.css('color', 'blue')}
    if ($('#mydiv3')) {.css('color', 'green')}
    ...

Open in new window

Is there a better way to check if the elements exist, with this naming convention? Something like a 'for each #mydiv(n) ' ?

OK. and there's no extra strain/load time for trying and then refraining from acting on nonexistent elements ?

Inside the box, I think the checking is done.

It seems some jQuery plugins generate error if the object don't exist...
