Hi All!
I''m kind of new o ruby so please apologize my stupid questions on
advanced...
I''m using
render :update do |page|
page.replaca_html :element , :partial => ''apartial''
end
This is working well, since I see in the page the following code:
try
{
Element.update("element", "");
} catch (e)
{
alert(''RJS error:\n\n'' + e.toString());
alert(''Element.update("element", \"");'');
throw e
}
I simplified the output.
My problem is that no script tag is generated and the code is not
executed!
How can I fix this?

I think render :update works different inside a view. You could, for example, stack up many render :updates inside one view <script> tag. But prefer using a controller, because "that''s what everyone else does".

You''ve asked controller to update HTML, so controller generated javascript to do that. You can then execute it on page. But if you used e.g. remote_function with :update parameter, then Ajax.Request expect some HTML from server to put into element you''ve specified. I think it is (almost always) better to use remote_function without :update argument, because it gives you more flexibility (not just updating contents of single element). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

render :update is meant be used in the controller as a response to an AJAX request, it returns pure javascript that will be executed by tha AJAX code that called the action ... so of course there are no <script> tags. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I used it in the controller. And it did what I was expecting! Anyway, I''m using this do display the errors in a specific part of my html, so this is no response to a request. The following quote is from the manual "Use this in your Ajax response bodies, either in a <script> tag or as plain JavaScript sent with a Content-type of "text/javascript"". So, this is my question, how do I do that? How can I add the script tags? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Someone asked if you were doing a response to an Ajax request. You are apparently injecting JavaScript when the page first paints.> The following quote is from the manual "Use this in your Ajax response > bodies, either in a <script> tag or as plain JavaScript sent with a > Content-type of "text/javascript"". > > So, this is my question, how do I do that? How can I add the script > tags?You ensure that the strings with <script> appear around it. If it''s in your controller, and if you are not rendering an Ajax-style request, then use ''<script>'' + and + ''</script>'' around the string it returns. If you are inside a view, go <script><%= render :etc %></script> Note that there are few reasons to do the former. Yet there might be many reasons to do the latter - sharing the first-paint code with the update code, for example. And note a purist would need the type=''text/javascript'', the // CDATA escape things. I don''t know what function returns those. -- Phlip http://c2.com/cgi/wiki?ZeekLand <-- NOT a blog!! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
