render :update returns js wrapped in a HTML body

render :update returns js wrapped in a HTML body


From what I'm learned the below is suppose to return "alert('Im JS');"
to the javascriptGener ator that's suppose to make the page scream 'Im

1. render :update do |page|
2. page.call :alert, "Im JS"
3. end

In Rails 1.2.3 it works perfectly.

BUT in Rails 2.0.2 it returns the js neatly wrapped in a full HTML-body,
and the browser shows me nada... (!)

Please help me here, I've tried everything I can think of for hours now!

Random things I've tryed (not in any order, and just glimpses)
use the page/hi.js.rjs approach

1. :text => "alert('Im JS');", :content_type => "text/javascript"

1. respond_to do |format|
2. format.js
3. end

1. headers["Content-Type"] = "text/javascript; charset=utf-8

1. render :update, :layout => false, :content_type => "text/javascript" do
2. |page|
3. page.call :alert, "Im JS"
4. end

Thank you all in advance!

I don't know about Rails 2.0.2, but in Rails 1.2.3
Expand|Select|Wrap|Line Numbers
  1. render :update do |page|
  2.   page << "alert('Im JS')"
  3. end
writes the raw JavaScript to the page.

I am sure this is an easy question, but being relatively new to ASP.NET programming, I can not quite grasp what I need to accomplish what I need to do. What I have is a word document that is rendered as a page (or actualy a part of a page) that is editiable. To do this I let the user download the document, edit it and then upload it back to the site. Then at Page_Open, I convert the .doc file to an html and render it back to the page......

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
