[RJS] How can i reload a script.

I met a problem about reloading a script.

Below is the source code.

display.rhtml:
{{{
<%= text_field_tag :title %>
<%= observe_field :title, :frequency => 0.5, :url => { :action =>
"update" }, :with => "title" %>

<div id="preview">
   <%= render :partial => "script", :object => @script %>
</div>
}}}

_script.rhtml
{{{
<%= @script %>
}}}

@script is a variable whose content is a javascript code, like
"<script type="text/javascript"
src="http://xxx?title=xxxx"></script>"

preview_controller.rb:
{{{
def update
    title = params[:title]
    @script = xxxxxx   <-  regenerate the script due to the title
change.

    render :update do |page|
       page.replace "preview", :parital => "script",
:object =>
@script
    end
end
}}}

I can see the display of script at first. But when i change title, it
just disappeared. I saw the response through firebug, which is like
"try { Element.update("preview", "<script
type=\"text/javascript\"
src\"http://xxx?title=xxxx\"></script>") }
.........."   But i can''t see
the effect in my page.

i don''t know why it didn''t work well. Thanks for your help.

Re: [RJS] How can i reload a script.

Hi, I guess that I have had success doing the following:

a)  edit the Javascript or RJS
b)  restart webserver or clear your cache

It appears that the Javascript and/or RJS gets cached during server
runs.  Thus, I simply restart the server to clear the cache. This
doesn''t happen all the time but restarting the server ensures that
I''m
running the latest code in my code base.

Good luck,

-Conrad

Re: [RJS] How can i reload a script.

Hi. That''s not what i want.

I want to give user a preview of the script result.  And the result is
changed when user input different title.

So, i can''t restart webserver or clear the cache.
