Hi All, I''ve be looking all over for a definitive answer to this question but it''s eluding me. There are many, *many* examples of the use of observe_field that include :on => ''keyup'' -- supposedly allowing one to bind an onkeyup event to a form element, etc. I have tried every-which-way to get this to work and it does not. When I bore into the code of prototype.js, I can see why: the binding has the ''change'' event hard-coded into it -- Event.observe(element, ''change'', this.onElementEvent.bind(this)); . . . and when I edit it to ''keyup'', it does, in fact, catch the onkeyup event. This being the case, how in the world do people get this to work with something _other_ than a change event -- barring a re-write of the prototype code? For reference, I''m using RadRails on Mac OS X 10.6 with rails 2.3.4 and prototype.js 1.6.0.3 Thanks in advance, Mark -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
