[google-appengine] Re: Show processing message to user while Urlfetch works

2009-05-11 Thread Jason (Google) 
Hi Jim. As noted in
http://code.google.com/appengine/docs/python/runtime.html#Requests_and_CGI,
App Engine does not currently support sending data to the user's browser
before exiting the handler. Your best bet is to use a JavaScript/AJAX
solution like the one djidjadji suggested.

 The problem with both of them is that they wait until the function is
 done before they output anything.   Saying I'm starting the lookup
 doesn't work so well when they see it after the fact ...

 I've done about 90 minutes of Googling and looking at the Django docs
 and am coming up empty.

 Thanks!

Thanks very much for the suggestion!

I found a solution along the lines of what you were suggesting here:
http://www.netmechanic.com/news/vol8/javascript_no2.htm

This: a href=http://www.netmechanic.com/promote.htm;
onClick=javascript:return confirm('Would you like to increase your
search engine rank?')Improve your site!/a  provides a cancel/OK
box with message and that seems to work fine.

Your solution is better  because it stays on the page rather than
going to another page.   So I will probably come back to it later.

Thanks again.

 Use the method in the page. Don't use a submit button but a a tag
 with an onClick attribute.
 In the Javascript function update some div id=lookup/div Tag
 with the I'm starting the lookup text and then submit the form.
 When the request is ready the page will update.
