Rails spinoffs - Jan 2007 - Prototype not processing javascript

I''m trying to change over from Rails 1.1.6 to 1.2.1 and have discovered
that either something is wrong with Prototype of else something has
changed that I am not aware of and cannot find documentation on. (I
just joined this group, so if this has already been cussed and
discussed here or in another list then please point me in the right
direction.)

I am trying to use the "replace_html" feature, and instead of
prototype
processing the generated javascript, I get a big load of "try
{Element.update( ...lots of javascript garbage... ) throw e }" dumped
onto my screen in place of where the updated html should be.

I encountered the same problem when I tried to work around it by using
"replace" to swap out the whole element with updated innerHTML. The
only way I could get around this problem was to use "replace" while
changing the element id every time. (Which results in more code than
should be necessary)

Basically, whenever I try to update an element, the javascript doesn''t
get picked up by prototype unless the id of the target element gets
changed in the process.

Is this a bug or am I completely missing something here? I''ve only been
using Rails for a couple months now, so I''m a bit new at this...

Thanks,
-Reuben

I''ve been having the same difficulty...  Although I''m not
using Rails
(I really wish I was).

I''m using AJAX.Updater to make calls which in turn populate various 
DIV''s with data.  However, none of the JavaScript gets executed 
(despite evalScripts being true).

I''m trying to use AJAX.Updater to populate a DIV with a Dojo widget 
but all I''m getting is plain text and the widget won''t render.

I think this is very common and all I''ve seen are little hacks to get 
code to work but I can''t see to get any of them working correctly.

Take care,
-Matt

Can you either put a minimalistic reproduction online for us to tinker 
with (that would be best), or failing that, post the *exact code*
you''re
using for the request (with details about what values you''re using that
the code alone doesn''t show, such as form values, etc.) and the *exact 
dump* of the AJAX response?

What Mime-type is the Dojo script sending?

Quick background on the site... Index.cfm (Coldfusion, ugh) has 3 
DIV''s that get populated with various AJAX calls.  The main content 
DIV gets populated based on an AJAX.Updater call from one of the other 
DIV''s.  Inside the data that gets populated in the main content DIV 
has a DIV inside itself.  I would like to click on an item in my 
content DIV (which was placed there from an AJAX.Updater call) and 
populate a DIV.

Here is some code...
// AJAX.Updater call to populate the DIV inside the main content DIV
// This works fine but it puts plaintext in the DIV and not the 
rendered widget.
function getLrudetail(selected_value){
	var url = ''getlrudetail.cfm'';
	var pars = ''id=''+selected_value;
	var target = ''lruSpace'';
	var myAjax = new Ajax.Updater(target, url, {method: ''get'', 
parameters: pars, evalScripts: true});
}

//getlrudetail.cfm - The content I want to populate the DIV (rendered)
<meta http-equiv="Context-Type" content="text/html;

    I''m the first tab and my content is local. Try clicking tab#2. 
It''s loading remotely.
    <input type="checkbox" name="cb1" id="cb1"
dojoType="Checkbox" />
    <label for="cb1">hello world</label>
  </div>
  <a dojoType="LinkPane"

refreshOnShow="true" style="display: none">Tab

  <div dojoType="ContentPane" label="Tab 3"
style="display: none">
    <h1>I am tab 3</h1>
    <p>Did you know that the children of a TabContainer can be any 
widget, such as a SplitContainer or LayoutContainer? The next tab is 
itself a TabContainer...</p>
  </div>
  <div id="subTabContainer" dojoType="TabContainer"

dojoType="LinkPane"
href="../../tests/widget/tab2.html"
selected="true">SubTab 2</a> </
div>
</div>
</body>
</html>

getlrudetail.cfm viewed by itself works fine, the Dojo widget is 
rendered and it works great.  However, when I use it with AJAX.Updater 
all I get back is plaintext with no rendering.  I know evalScripts: 
true ignores inline JavaScript or something but I quite haven''t 
figured out the hack to get it to work the way I want and have the 
Dojo widget render itself.

I''m guessing I have a scope issue somewhere since I''m
essentially
populating a div inside another div each populated by AJAX.Updater 
calls.

Not much of a JavaScript guru so any help would be appreciated.

This site is for internal use only so this is the best I can do for 
posting code.

Thanks!

@Matthew Williams: Thought I would post in case you hadn''t figured the
problem out. (I got help on another list) The source of your problem
is that you''re using AJAX.Updater instead of AJAX.Request. Use the
Request method when you expect to get something that is more than just
plain text, i.e. javascript.
