javascript_tag replacing whitespaces w/ '%20'

Hello,

  I have a form that tests if a title has been changed since the page was
loaded and the page has been submitted. If the page title has been changed
then a confirm box will ask if the user wants to have the title changed.
The problem is if the person hits cancel, all white spaces in the title get
replaced w/ '%20'.

Here's the code I was using:

[code]
<%=javascript_tag( "function confirmSubmit(){ var page_title_before= '#{u
@page.title}';
                                              var page_title_on_submit =
escape($('page_title').value);
                                            if( page_title_before !=
page_title_on_submit ){
                                                var agree=confirm('Changing
the title of this page will break any links or bookmarks that refer to
it.\\nPress \"OK\" to save with the new title, or \"Cancel\" to revert to
the original title.');
                                                 if(agree){ return true; }
                         else{ alert( 'page_title_before-->>' +
escape(page_title_before) ); $('page_title').value = page_title_before;
return false; }
                                            }
                                              else{ return true; }}") %>
[/code]
