shane18 Posted May 21, 2010 Share Posted May 21, 2010 Why if you send a xmlhttprequest u need to put send(null) ... why can't you just put send() why is the "null" required... is it because this function doesn't have a default value for its argument which makes it a requirement? because most php functions for example have optional arguments so if u don't need to set a certain value for a argument it just ignores it...
