Question

well, could anyone give me some support doc for render :update method
until now i’ve only know about the page.alert method and page.replace_html method.

Here my testing code.

render :update do |page|
  page.alert(get_notice_str)
  page.replace_html "tr_01", :partial => 'goods', :object => goods
end

luckly it works fine.

now, i got a test function like set the disabled button true for the page, but i’ve no idea which method could help me out.

Answer 1

It can be done like this:

render :update do |page|
  page << "$('#elem').attr('disabled', 'true')" # or any JS you want
end
