It would be nice to be able to use the * character as a wildcard in calls to .removeClass().

For example, elem.removeClass('foo-*') would remove all classes that start with foo-.

Currently, the easiest way to do this seems to be the following, which is neither elegant nor efficient:

.removeClass(function (_, cl) { return cl.split(' ').filter(function (c) { return c.substr(0, "foo-".length) === "foo-"; }).join(' '); })
