Volker, I've been playing with the dojo.io.bind stuff lately, after having used Prototype for awhile, and there indeed is no built-in equivalent to the Ajax.Updater in Prototype.
BUT, what Ajax.Updater does can be pretty easily replicated in your own javascript class, as what it is actually doing behind the scenes is relatively simple. In many other cases, I have tended to find that the Ajax.Updater stuff is overly simple, and I've needed to use custom responders anyway. By default, Ajax.Updater just uses innerHTML to do the replacing of your "container" with any HMTL returned from the server. If that is all you need (along with eval'ing any script blocks), it is pretty easy to replicate in your own handler method. In my own experience, I've needed more than this. For example, what if you need to refresh multiple components on the page that are not all children of some "ajax zone" sort of container? I.E., the "partial rendering" approach. Then you would generally have multiple fragments of HTML returned that all need to be treated separately. Ajax.Updater does not handle this directly, but I've found that dojo has some utility methods such as dojo.html.createNodesFromText that make this pretty easy to do in a custom handler. I'd be happy to take a look at any Tobago code you have in mind and assist in converting it over to use dojo. - Jeremy -----Original Message----- From: Volker Weber [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 18, 2006 7:42 AM To: MyFaces Development Subject: Re: Which Javascript library to use for AJAX components? Hi, dojo.io.bind is a replacment for prototypes Ajax.Request. the Ajax.Updater replaces the content of a html element with the response of a ajax request, including optional evaluating of javascript content. e.g ---------- begin html ---------------- <div id="divId" > [ any content. e.g. complete tobago sheet] </div> <button onclick="replaceDivContent('divId')"> Do ajax request</button> ---------- end html ---------------- ---------- begin javascript ---------------- function replaceDivContent(id) { var options = { method: 'post', asynchronous: true, parameters: '', evalScripts: true }; var div = document.getElementById('id'); // Tobago.form is the html form element var url = Tobago.form.action + "?affectedAjaxComponent=" + id + '&' + Form.serialize(Tobago.form); new Ajax.Updater(container, url, options); } ---------- end javascript ---------------- Regards, Volker Gerald Müllan wrote: > Hi Volker, > > Yes, sure.
