Hey. Below is a patch to allow generic Ajax.Autocompleters. Basically
it''s for people who wanna be able to watch an input for changes, but
don''t want it to pop up an autocompleter box below. Useful for live
previews, that kind of thing.
Someone''s gonna have to fix the tabstops. I couldn''t be arse
to work out
how to make vim do the softtabs properly. Spaces for indentation is
stupid anyway.

Re: [PATCH] Allow generic autocompleter (Ajax.Watcher)
Um no, in-house project, but it''s not difficult. new Ajax.Watcher(element, url, callback, options); Callback receives the ajax response. It gets passed to onSuccess in Ajax.Request. One interesting options - firstRun (bool), set whether the ajax request + callback should be performed on instantiation or not. Default not. -Rob Deco Rior wrote:> Do have an example for this > On Feb 13, 2006, at 10:10 AM, Robin Haswell wrote: > >> Hey. Below is a patch to allow generic Ajax.Autocompleters.
