[Proto-Scripty] Re: How to handle non-JavaScript browsers when using Ajax.Updaters for content
True. We actually dabble in Catalyst w/ Template Toolkit, but so far have
actually found it far more intrusive that helpful to our online application,
hence we're hand coding everything on the production site to-date [using
handmade HTML, PHP, Prototype, LivePipe, and a dash of Scriptaculous!).
I also completely agree that the use of Ajax is to optimize in
new-and-awesome ways for the user experience, which strictly speaking has
the exact effect you mention: extra work coding to make those optimizations
happen.
With that said I refuse to make things ugly server side because we want to
optimize past web 1.0 using an Ajax framework yet maintain backwards
compatibility. I'm going to push on with this problem and hopefully come up
with an elegant solution to the hybrid goal of Ajax-y goodness and SEO
(which is the real reason anybody should care about non-JavaScript support
IMHO).
I'll of course post back with anything we can come up with...
cheers-

Yes, I was oversimplifying. If you use an MVC system, you shouldn't ever
have to worry about headers, footers or nav bars.
With MVC, the layout template echoes your content. When requested by ajax,
the layout template will be blank. Otherwise the layout template will be a
complete page minus the content. For example:
empty.phtml:
-
?php echo $content ?
htmlHeadAndFootAndNav.phtml:
-
html
head.../head
body
div id=page
div id=header
div id=navigation.../div
/div
div id=content
?php echo $content ?
/div
/div
/body
/html
myContent.phtml:
-
?php ob_start() ?
pContent.../p
?php
$content = ob_get_clean();
if ($_REQUEST['ajax']) {
include 'empty.phtml';
} else {
include 'htmlHeadAndFootAndNav.phtml';
}
?
Ajax isn't traditionally used to make less work on the server side; it is
usually implemented to reduce page load times and allow immediate feedback
for simple actions. If you're looking for better content management, start
with a CMS or an MVC framework on the server side.
Oops, that was a long answer. :P

[Proto-Scripty] Re: User types freely on webpage and it jumps to a link...
Yes you could just setup a keyup observer on the entire document, the two problems that I see right away is that any keyboard shortcuts the user already uses may or may not work any longer depending on how you write your code. Secondly, depending on the size of the list of links, the script may take a while to process each keypress. There's a few other issues I'd be concerned with, but the above is probably enough to think about for now. Having a textbox to type into would solve the first problem. Keeping a copy of the list of links in a local variable would help to solve the second problem. -justin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

this code is unsafe. findFirstElement() function returns empty value,
if form has no elements. look at this:
var elements = $(form).getElements().findAll(function(element) {
return 'hidden' != element.type !element.disabled;
});
so, our solution is to rewrite focusFirstElement like this:
focusFirstElement: function(form) {
form = $(form);
var element = Form.findFirstElement(form);
if(!Object.isUndefined(element))
element.activate();
return form;
},
What do you think?
Good catch.
I think there's no need for `isUndefined`:
focusFirstElement: function(form) {
form = $(form);
var element = form.findFirstElement();
element element.activate();
return form;
}
Could you please file a bug report.
Thank you.

As you see above, I'm setting the value of id from li to the

Basically, assume follwing sequence:
1. I'm typing xyz in the textbox
2. I got the result selected xyz.
3. Due to the selection, company_id is set from li
4. Now, I deleted xyz from text box entered couple of spaces or some
other character which does not exist in database.
5. The result didn't show up since no match occured.
6. However, the company_id is still set to the earlier value of xyz's
id. This is causing problem when the form is submitted to the next
page.
How can I unset the earlier value of selection?
Thanks!

Ah right, yes that makes perfect sense.
What if the date were to be serialized as new Date(...)?
For example,

var evaluated = input.evalJSON();
var v1 = evaluated.dob.toString();
// v1 == Wed Sep 03 2008 15:55:56 GMT+0100 (GMT Daylight Time)
var v2 = evaluated.dob.getDay();
// v2 == 3
Would there be any nasty pitfalls with this approach?
