Then I will write a tutorial for it in a few weeks, because it really isn't hard. I am just using Zend_Layout for it which is using Zend_Json.
But I am not mixing HTML and Javascript in one request, like you can see in my current 'ajax' layout:
<?php
if (!isset($this->info)) {
$this->info = array();
}
echo Zend_Json::encode(array(
'content' => $this->layout()->content,
'title' => (string) $this->headTitle(),
'preExec' => $this->placeholder('preExec')->toString(),
'postExec' => $this->placeholder('postExec')->toString(),
'info' => $this->info
));
Currently, I am busy to make that I am using the headScript() and inlineScript() helpers instead of the preExec and postExec placeholders. My ideas are to add a 'modules' key with the information from $this->dojo()->getModules() and a 'onload' with the onload information.
But about that JS expressions, what kind of problems can there be when I am putting my Javascript into a JSON string and using eval() to execute that?

The theory is simple: First I will have to get the Dojo modules that are required, by the getModules () method. Those modules I can give to Zend_Json which puts them into a JSON array. Then, the JavaScript will loop trough all those modules and executes dojo.require() statements for each of them. Also, I can use the getOnloadActions() method to retrieve the scripts for that, which I will push into my JSON response, loop trough them in Javascript and use eval() to execute them. The same I can do with the HeadScript and InlineScript helpers.If you can manage it, please write up a tutorial showing how you accomplished it. The problem I alluded to is that Javascript will not execute <script> tags returned by XHR requests. You can certainly write a handler for JSON responses, however, that could do as you suggest; the difficulty there would be if you want to mix HTML and JS. Additionally, you may have some issues with encoding JS to insert into JSON until we get JS expression support added to Zend_Json (this proposal is up for review now, however, and may be included for 1.7.0).Matthew Weier O'Phinney schreef: -- Pieter Kokx <pieter@kokx.nl> wrote (on Saturday, 18 October 2008, 04:39 PM +0200): Currently I am busy with a project that loads every page with an AJAX request. But that is giving me a problem with Zend_Dojo. When I am using Zend_Form, it will render the Form correctly, but it doesn't load the Dijit form widgets. It is because I can't execute the dojo.require() statements in the AJAX requests. Currently, I am giving some JavaScript with the AJAX response, but I don't know how to retrieve the dojo.require() and onload statements from the dojo view helper. Does anybody know how I should take this problem and get the dojo.require() and onload statements from the Dojo view helper, so I can include them in the AJAX response and execute them on the client side? You can't, unfortunately; it's a limitation of Javascript. The way I tackled it with the pastebin demonstration application was to create a Dojo layer that performs all the dojo.require statements I need; this also makes it trivial to create a custom build later to speed the entire application up. You can see the build file here: http://github.com/weierophinney/pastebin/tree/master/public/js-src/paste/layer.js The important aspect is everything up to the first dojo.addOnLoad() statement. If you pay attention to it, basically I'm requiring everything I may possibly need in any XHR requests I make, as well as the requires necessary for the initial page load. When you create a custom build with this layer file, all those will get compiled and in-lined to a single file -- making for a concise, single file with all functionality.
