Function removes css class names from element class
attribute.
Supports regexp as a class name (thing I wait from jQuery for years).
Preserves order, leaves no duplicate or trailing spaces in className
.
Regexp should be matched fully, not partially.
/foo-.*/
will match 'foo-bar'
in 'foo-bar baz'
/foo-/
will not.
^
and $
means start and end of class name chunk, not of the whole className
string
i
(case-independent) modifier search is supported
m
(multiline) modifier has no meaning
g
(global) modifier is ignored: all search behaves as global
removeClass(o, c)
o
required object whose className is changed
c
required class name: regexp or string (or anything that coerces to string, excepting null
and undefined
)
Returns: nothing
there are two ways to do this: 1. select additional spaces and replace not with f, but with x+' ' (+trim) or 2. use a new string (written off-hand, not tested):
function(o,c,r){r='';o.className=o.className.replace(/\S+/g,function(x){(c.exec?(c.exec(x)||0)[0]:c)==x||(r+=x+' ')}),r.trim()}
