Remove all classes that begin with a certain string

I have a script which adds one of six classes randomly to the body. The classes are numbered between 1 and 6, like this:

theme-1 to theme-6.

I need a clean way to remove all of them. Right now I have this:

$('body').removeClass('theme-1');
$('body').removeClass('theme-2');
$('body').removeClass('theme-3');
$('body').removeClass('theme-4');
$('body').removeClass('theme-5');
$('body').removeClass('theme-6');

But it’s kind of clunky right? Is there a way I can say “remove any classes between theme-1 to theme-6“?

Answer 1

You can use the loop index to generate class names.

classes = ""
for(i=1; i < 7; i++)
   classes += 'theme-' + i + " ";
$('body').removeClass(classes);
