Rails spinoffs - Dec 2005 - ajax - multiple updates on single xmlhttprequest

Hello,

I was wondering whether anybody would share a working example of a multiple 
html update on a single xmlhttprequest.

Thank you in advance for your help.

Use RJS:

If you''re not using Rails, you can still achieve this by using  
Ajax.Request for your
Ajax calls (not Ajax.Updater!), and send back a "Content-Type: text/ 
javascript" HTTP header,
then just JavaScript in the response body (without "<script>"
tags).

This will cause Prototype to automatically evaluate the returned  
JavaScript so you can
do multiple updates:

$(''element'').innerHTML = ''this and that'';
$(''anotherelement'').innerHTML = ''blah'';

Of course, Rails makes that all much easier because stuff like  
correctly escaping chunks
of HTML for JavaScript is build right in.

Thanks for getting back to me - I''m afraid this is not helping me much,
since I''m not using Rails.

Thanks anyway

I''ve successfully used JSON. Here''s a stripped down example:

// ---------------------------

// Handler function: is executed after successful Ajax.Request
var handlerFunc = function(t)
{
  // Evaluate returned JSON data
  var evalObj = eval(t.responseText);
  
  // Update info container
  $(''someId'').innerHTML = evalObj.foo;
}
// Bind the function and do the Ajax request
new Ajax.Request(''script.pl'', {
  parameters: ''id=42'',
  onSuccess: handlerFunc
});

// ---------------------------

In the example "evalObj.foo" matches "({foo:"bla
bla"})" in JSON. And "bla
bla" will be written into the innerHTML part of the (X)HTML container with 
css id "someId". Hope that helps.

Let me just add here, that i''m pretty new to script.aculo.us myself, so
if
anyone knows a better way of doing this, please let me know. Like the OP
i''m
looking for a good XML example without Rails too.
