Hide a DIV [Rails]

Question

Hiding a DIV would be easy enough in Javascript, but is there some Rails-y way to do it? I can think of some ways to do it by calling Javascript from a partial (.erb), of course, but I'd prefer not to write any Javascript at all. Possible?

Edit: The page is loaded and I would like to hide the DIV after (well, on) an Ajax call, so I'm in one of those render :update blocks.

Answer 1

Don't really know rails, but can you just output something like style="display:none;" into the div tag?

Answer 2

To render an RJS update from your controller:

respond_to do |format|
  format.html
  format.js { render(:update) { |page| page.hide('element_id') } }
end

You can look up the API for other RJS responses.

Answer 3

render :update do |page|
    page.hide 'div_id'
end

You can throw this in you respond_to block or an RJS template.

Another helpful tip, using the same syntax:

render :update do |page|
    page << 'arbitrary javascript code goes here.'
end

Answer 4

Or, right in your view:

<%= link_to_function "Toggle", "$('#some_div').toggle();" %>

Answer 5

<%= link_to_function "Toggle", visual_effect(:toggle_blind, "some_div") %>
