For the :frequency param in the docs, it says: The frequency (in seconds) at which changes to this field will be detected. Not setting this option at all or to a value equal to or less than zero will use event based observation instead of time based observation. I''d like my field to make an ajax call for the onkeypress event, rather than every 1 second or so. I thought it might do this if I omited :frequency, but it doesn''t seem to do anything. Is there a way to set this? -- Posted via http://www.ruby-forum.com/.
