Hi all, I work a lot with scripts that modify the DOM, and I have always found quite annoying that the code would always get very verbose as soon as I wanted to create even simple structures : var my_div = document.createElement(''div''); var my_anchor = document.createElement(''a''); my_anchor.setAttribute(''href'',my_link); var my_text =

Hello everyone, I am working with rjs templates in rails, and I''m amazed of how simple it is to generate code with ajax, however I''am having some troubles and I can''t seem to find a way to solve''em.

The flicker I am seeing in IE is really really bad with SlideDown/SlideUp. The element I am sliding is a div that contains a table. The tables are stacked on top of each other so that the presentation actually appears as a single table. When I SlideDown, the toggled element flashed into view then disappears before sliding down. On SlideUp it slides up then flashes into view for a split

I have a fixed height scrollable div inside another div that controls the slideDown and slideUp effects. This causes a really bad flicker in Firefox (1.0.7) for the entire duration of the slide down and up. While on the other hand it works smoothly in IE (except that on a slideUp it causes a last second flash that shows the entire div). Any ideas on how I can fix this? Thanks.

I''m using scriptaculous'' SlideUp and SlideDown effects to animate a menu. Specifically, I SlideUp, make some CSS changes, and SlideDown. All works well, except that for a split second in between, the element''s display becomes ''none'' and the other menu item jump into the space. I haven''t been able to find any way to force an element to retain

I want to do some DOM manipulation with JavaScript. Specifically I want to implement zoom in/out in a picture by changing it''s width/height attributes. Is it possible to do this using RJS or should I write javascript by hand? All the examples of RJS I''ve seen write the javascript in the result of an AJAX remote call. Where are the docs for RJS? All I''ve seen are blog

Hi, I am currently reading the Rails Recipes book and like the chapter on providing your own in_place_editor for enumerations / selects. I understood so far, or I believe that I understood ;-), how to do that for a field that uses values only, like choosing from "red", "black", "green". What I fail to understand is how to chose from associated objects?!

How can I slow/speed up the combo effects? Thanks

Hello, I''m hoping this is the right place to ask these kind of questions. If not, please excuse me. Anyway, the problem I''m having is that I have a HTML table showing some tabular data and I want to use Effect.SlideDown/Up to allow the user to interactively show "details" for each item (<tr><td> etc) in that list.
