Hi. I need help on what is essentially putting an "onload" event handler into a div. I am using render :partial and when the partial is loaded, I would like the divs to show using an effect from a library such as scriptaculous or moofx. However, there is no "onload" for a div. I was wondering what alternative methods I should use to achieve this.

Thanks!

If you put the j-script you want to execute in a <script></script> block that appears immediately after the div, and have the script execute immediately, then it will only run immediately after the div is in place.

E.g.:

<div> content content content </div>

<script type="text/javascript"> function do_something_to_div() { ... }

do_something_to_div(); </script>

here's an example: this is in an RJS file called create.rjs:

page.visual_effect :blind_up, "new_comment_form_for_post_#{@post.id}"

this is called from the create action of a controller....in the create action would be something like this:

respond_to do |format| format.js end

which would call the RJS...the RJS does the scriptaculous effect that makes the div roll up like a blind....the div id is in the speech marks after the :blind_up command.....
