Why doesn''t evalScripts evaluate external js files

Hello everyone,
Here is my problem. I have a page that gets fetched by an ajax
request. I have

onComplete: function(transport) {
$(''element'').update(transport.responseText);
}

The update in turn calls evalScripts and runs all of the javascript
inside of script (<script></script>) tags, but I also have linked
javascript files (<script src="whatever.js"></script>) in
the
requested page that evalScripts doesn''t handle.

I''m just wondering why prototype doesn''t handle these included
scripts? Is it a conscious design decision?

Thanks,
James Starmer

new Ajax.Request(url,{

				onComplete: function(transport) {
					tab.linkedPanel.update(transport.responseText);
				}
			});

tab.linkedPanel is an empty <div>.

Re: Why doesn''t evalScripts evaluate external js files

Looks like you may actually want Ajax.Updater, which has an  
evalScripts option.
http://prototypejs.org/api/ajax/updater

new Ajax.updater(tab.linkedPanel, url, {
   //method: ''post'', //Is already default method
   //parameters: Form.serialize(''formId''), //Do you need to
pass any
parameters?
   evalScripts: true
});

Does that work for you?

Re: Why doesn''t evalScripts evaluate external js files

Tom,
That didn''t really help, thanks though. The .update (aka
Element.update) calls evalScripts.
>From the api http://www.prototypejs.org/api/element/update :"If it contains any <script> tags, these will be evaluated after
element has been updated (Element.update internally calls
String#evalScripts)."

So using Ajax.Updater vs. Ajax.Request isn''t the issue.

I don''t have trouble with evalScripts handling scripts that are in the
page being fetched by ajax. My problem is when that page includes a
separate javascript file like <script
src="whatever.js"></script>.
evalScripts doesn''t handle those.

It''s more of a prototype design question than a help me with this bug
question because I don''t think it''s a bug.

Thanks,
James Starmer

Re: Why doesn''t evalScripts evaluate external js files

I see.

Have you tried passing Javascript that would load an external file? I  
mean, rather than passing <script src="..."></script>,
passing
something like the following:

<script type="text/javascript">
function loadJs (fileName) {
	var head = document.getElementsByTagName("head")[0];
	var s = document.createElement(''script'');
	s.type = ''text/javascript'';
	s.src = fileName;
	head.appendChild(s);
}
loadJs(''/js/someFile.js'');
</script>

Re: Why doesn''t evalScripts evaluate external js files

Thanks Tom,

I actually came up with a solution that uses that append code, but it
parses the source file names out of the code and loads them
dynamically when the ajax page is loaded.

I posted the script on my blog if anyone is interested.

http://www.jamesstarmer.com/2007/07/13/dynamic-script-loader/

Thanks,
James
