Question

Is there any better way to do this?

$('element').removeClass('class-1').removeClass('class-2').removeClass('class-3').removeClass('class-5') ...
to .removeClass('class-105')
:)

I want to remove all class-(n) classes.

Answer 1

Get the classes of the element, process it as a string, and put it back:

$('element').attr(
  'className',
  $('element').attr('className').replace(/\bclass-\d+\b/g, '')
);

Edit:

The attr method has since changed, and it no longer reads properties, so you have to use the attribute name class instead of the property name className:

$('element').attr(
  'class',
  $('element').attr('class').replace(/\bclass-\d+\b/g, '')
);
