Hi, I''m new in developint rails (but I love rails). I would like to react on changing a field in the view (no model field) from a selection box to show the number of rows (which I used in the controller).

I have two <select> objects. The first one (let''s use the standard example of artists/albums here) is pre-loaded from the page but I want the second one to load when the user changes the value in the first form.

Idea: Add onchange="document.forms[0].submit();" to every field Problem: Can not cancel form submission.

Hello, currently I''m working on a JavaScript-on-screen-keyboard for use with touch screens. To autocomplete inputs I want to use the Ajax.Autocompleter control. The problem is that Ajax.Autocompleter only responds to onkeypress events made with a real keyboard, but my on-screen-keyboard causes onchange events when a letter is clicked and appended to the input field. So, is there a way to
