Pop Up Window

Hey Guys, first post here.

I am running into some basic problems. I am trying to submit a form in
a popup window and if the object saves close the popup window and
refresh the page in the main window.

Has anyone done this, or know a good way to do this?

Sorry for such a stupid question, but I have ran around in circles
trying to do this.

Thanks

The best way to do it, in my mind, is to use an rjs template. In
your controller, your action would look something like this:

def my_action

do usefull stuff.

 render :update do | page |
    if @something.save
        page << "myCloseWindowJavaScript()"
    else
        page << "notifyUserOfError()"
    end
 end

end

where myCloseWindowJavaScript() and notifyUserOfError are javascript
functions you define in a .js file. You can also look at the
documentation for
ActionView::Helpers::PrototypeHelper::JavaScriptGenerator::GeneratorMeth

rjs / ajax could work (above post), but don’t forget to use <%
form_remote_tag %> rather than <% start_form_tag %> so the ajax works.
this could be a problem if you want to upload pictures in the popup
window (ajax does not allow this as of now) , so a different option
could be the following:

first of all, make sure the window is a popup that was ‘popped-up’ from
the MainWindow (if it is a target="_blank" the js functions won’t work
on it).
then, render js text:

or something similar.
hope this helps, and welcome to the forum!

:slight_smile:

 render :update do | page |
    if @something.save
        page << "myCloseWindowJavaScript()"
    else
        page << "notifyUserOfError()"
    end
 end

end

…wanted to fix myself;
note that doing render :update is actually rendering the javascript (and
not necessarily using ajax), so you should end up having something like

  render :update do | page |
     if @something.save
         page << 'window.opener.location.reload();'
         page << 'window.close();'
     else
         page << 'some_other_js_func();'
     end
  end

end
