If it''s a link, just add target="_blank" to the a tag. If it''s Javascript, there''s window.open(url, options*) IIRC.

Quickly,
Here''s an example of some code in a view to set up a link that will
open
up a new window to receive a PDF:
<%= link_to(''Forms and Endorsements'',
{:action => ''show_company_terms'',
:id =>
company.id},
:popup => [
''terms_and_conditions'',
''width=800, height=700, left = 450, top = 100, resizable,
scrollbars=yes'' ]) %>
This makes a popup window named ''terms_and_conditions''.
If you wanted the content to show up in the window, the action
''show_company_terms'' would need to use the send_file() helper
to send
back a PDF file. In the parameters for send_file, you would specify the
content-type.
Hope this helps.
Let me know if you need more info.
Wes

There is no option to that. One possibility is to make a custom button.

Bill,
My app. displays one of several PDFs depending on what is requested.
The view has a <FORM> tag with no attributes to allow the submission
attributes to be fully dynamic. Buttons invoke a Javascript function to
set up the form, submit it via an AJAX request that populates the popup
window with the PDF. The onSuccess code for the AJAX request hides the
AJAX wait message and graphic and then evals some Javascript returned
from the action that does whatever you want in the popup. In my case,
it causes the popup to do a redirect to an action which will render the
PDF (I couldn''t figure out a simpler way to do it). Currently,
I''m
using it to render 3 different PDFs.
1) View with button:
<%= button_to_function(''Save and Print Insured Forms'',
"submit_form_to_popup(this.form,
''print_application_window'',
''print_application'')", :style => "width:
200px;") %>
2) Javascript function submit_form_to_popup:
/* Takes a form object, a popup target name, and an action for the form.
AJAX-y wait graphic provided by default. */
function submit_form_to_popup(form, popup_window_name, action) {
form.action = action;
popup = window.open('''', popup_window_name,
''width=800, height=700,
left = 450, top = 50, resizable, scrollbars=yes'');
wait_image_url = window.location.protocol + ''//'' +
window.location.host + ''/images/indicator_verybig.gif'';
//Create a DIV in the popup window and populate it with the AJAX wait
message and graphic.
newDiv = popup.document.createElement(''div'');
newDiv.id = ''pdf'';
newDiv.style.marginTop = ''33%'';
newDiv.style.textAlign = ''center'';
newDiv.innerHTML = ''Please wait while your forms are
generated...<br/><br/>'';
wait_img = popup.document.createElement(''img'');
wait_img.src = wait_image_url;
newDiv.appendChild(wait_img);
popup.document.body.appendChild(newDiv);
//Submit the form asynchronously and execute Javascript returned from
the action.
new Ajax.Request(form.action, { asynchronous: true,
method: ''post'',
parameters: Form.serialize(form), evalScripts: true,
onSuccess: function(request) {newDiv.innerHTML = '''';
eval(request.responseText);}
});
return false;
}
3) Rails action that is the target of the AJAX request:
def print_application
#Create pdfgen object here
...
render :update do |page|
page.assign(''popup.location.href'', url_for(:action =>
''render_pdf'',
:filename => pdfgen.output_file))
page.replace_html(''notice'', ''The application was
saved
successfully.'')
end
end
def render_pdf
send_file(params[:filename], :type => ''application/pdf'',
:disposition
=> ''inline'')
end
Hope this helps,
Wes
