hi, i can''t figure out how to solve this problem:
i do a an ajax.updater, it works but i would like that the message
returned by the server "lives" only for 5-10 seconds and then
disappears.(like in Gmail, when you send/delete/etc a message a new
line appears for few second and then it disappears).
this is my function:
function addgr(){
var gr=$F(''form'');
var url= ''page.php'';
var par = ''add='' + gr ;
var target = $(''msg'');//the meassage that has to appear for
5-7
seconds
var addingr = new Ajax.Updater(target,url,{method:
''get'',parameters : par});
}
thanks.
cirpo

Use the onSuccess handler of your Ajax object to set a timeout to remove
the information you added. For example:
new Ajax.Updater("message_area", "get_new_message.php",
{
onSuccess: function() { setTimout("clear_message_area", 5000);
}
});
function clear_message_area() {
$("message_area").update(""); }
The onSuccess handler sets a timeout of 5 seconds (the number is in
milliseconds) after which it calls the clear_message_area() function.
That function then simply updates the content of the message_area
element with nothing effectively removing the message from the screen.

As Christophe indicated, setTimeout isn''t part of Prototype.js --
it''s
actually just part of JavaScript. If you search for "javascript
setTimeout" you''ll get more information. There''s also a
relatively
strong article at about.com regarding the similarities and differences
between setTimeout() and setInterval():

The server should be responsible of that task since that it is it who is responsable of the control flow in your app/Web page. I had to implement a similar system in my app, and since Prototype is a nice framework, he will handle whatever the server ask it to do automatically. Consider this : var options = { method: ''get'', parameters: par, requestHeaders: [''object'', ''TestUpdater''], // optional... evalScripts: true // execute any embedded scripts in the response }; new Ajax.Updater( ''msg'', ''page.php'', options ); And a typical response would be : <div id="msg3434323466792"> <b>Response is : </b>Hello world ! <script type="text/javascript"> setTimeout( function() { Element.remove(''msg3434323466792''); }, 5 * 60 * 1000 ); </script> </div> Since we did set ''evalScripts'' to ''true'', any <script> tag found will be removed and executed. The response should have, then, a tag with a very unique Id (usually composed from a timestamp) and the script executed by the update method of prototype creates a timer that will remove that tag later on. This way, you decouple your client from the responsibility of "cleaning up" the server responses. After all, it doesn''t matter from who, when, or where the request originated ; the client should only ask question, and handle events, not control the behavior of the interface. Hope this helps. -Yanick --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

Yes Rob, you''re right. In David''s defense, though, he was perhaps indicating that the solution could be found in nearly every Javascript book or tutorial ever written. Even those from the "dark ages" when Netscape Navigator was the hottest browser around. I don''t have much faith that someone lacking knowledge of setTimeout (and, it would seem, the ability to Google it) would understand the phrase "DOM Level 0." Besides, he''d be correct in saying the method will exist in every major modern browser implementation of Javascript. Cut the guy some slack. For most (hobbyist) programmers, the ubiquitously implemented BOM/DOM standards **are** "Javascript." I can understand the desire to be precise. I''m obsessive/compulsive/ passive/aggressive/etc. that way too. =) TAG On Apr 11, 2007, at 1:26 AM, RobG wrote:> On Apr 11, 9:36 am, David Dashifen Kees <dashi...-NT0ononE2K1Wk0Htik3J/w@public.gmane.org> wrote: >> As Christophe indicated, setTimeout isn''t part of Prototype.js -- >> it''s >> actually just part of JavaScript. > > Nope, it''s part of DOM Level 0, it''s a method of the window object.--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.
