[Proto-Scripty] Appending a template evaluation to an HTML element.

2010-08-17 Thread Richard Quadling
Hi.

I've implemented a simple add new user button to my amend users
page. The user list is only about 20 people, with
name/email/pin/contracts/delete options.

The button calls a template evaluation and that is within an update ...

$('vsNewUsers').update($('vsNewUsers').innerHTML +
tmpl_NewUser.evaluate({NewUserID : --i_NewUserID}));

All working fine.

I like how it works, but I wonder how I can just append the result of
the evaluation.

How do I take a template and append the results to vsNewUsers.
vsNewUsers is a tbody element and the template is a tr element with
all the td's needed.

var tmpl_NewUser = new Template('trtdinput type=text
name=User[#{NewUserID}][Username] value= maxlength=200 size=50
//tdtdinput type=text name=User[#{NewUserID}][Email]
value= maxlength=200 size=50 //tdtdinput type=number
name=User[#{NewUserID}][PIN] value= maxlength=4
//tdtdinput class=vsaAllContracts type=checkbox
name=User[#{NewUserID}][AllContracts] value=1
id=allContracts_#{NewUserID} //tdtdinput type=text
name=User[#{NewUserID}][ContactIDs] value= maxlength=200
disabled=disabled size=50 /input type=hidden
name=User[#{NewUserID}][ContactIDs] value=/tdtdbutton
class=vsaChooseContracts bold
id=selectContracts_#{NewUserID}Select
contracts/button/tdtdinput type=checkbox
name=User[#{NewUserID}][Delete] value=#{NewUserID} //td/tr');

I'm thinking no.

Regards,

Richard.

[Proto-Scripty] Safari problem in Accordion with Flash content

2010-08-17 Thread Walter Lee Davis
Can anyone explain why I might see the following? I have a simple  
Accordion effect made with Scriptaculous:


var tog = function(){
var params = {duration:0.2};
if (this.next('p')) {
Effect.toggle(this.next('p'),'blind',params);
}else{
if(this.up().next('p')){

Effect.toggle(this.up().next('p'),'blind',params);
}
}
};

It works fine in all browsers. But while watching the page in Safari's  
error console, and clicking the header over a Flash movie, I see an  
incrementing error related to the Flash movie itself: Failed to load  
resource: cancelled. If I open and close the accordion effect, hiding  
and showing the Flash movie, the page works perfectly, but that error  
repeats every time after the first time the movie shows. The other  
header on the page reveals a static JPEG image, and nothing happens in  
the console when that opens and closes.


Here's a live example, extracted from my Rails project, if you want to  
see it in the wild. http://scripty.walterdavisstudio.com/problem


Thanks,

Walter

[Proto-Scripty] scriptaculous causes body background to fail on safari and chrome

2010-08-17 Thread Guillaume Lepicard
Hi all,

i have a very simple document:
!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Transitional//EN 
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd;
html xmlns=http://www.w3.org/1999/xhtml;
head
titleBG fail/title
style type=text/css
body {
background-color: #00;
color:#ff;
}
/style
script type=text/javascript src=lib/prototype.js/script
script type=text/javascript src=lib/scriptaculous.js/script
/head
body
h1Hello/h1
/body
/html

On chrome and safari, the black background stops right after the h1 hello.
On safari, if i ask for the page source code, right after the code window
appeared, the background gets back to normal.

If i remove scriptaculous inclusion, no more problem.
If i move the style declaration after the script tags, no more problem (it
took really long to figure out what went wrong...).

Am i missing something? is it recommended to move the style declarations (or
imports i tested with external css) after scripts? is it a safari and chrome
(webkit?) bug?

Thanks
Guillaume

[Proto-Scripty] Re: 4 different browsers - 4 different responses

2010-08-17 Thread T.J. Crowder
I don't see how this went too far afield at all -- at least not nearly
enough to bother to comment on it.

Richard had some Prototype-related code that wasn't doing what he
wanted and he also mentioned the target attribute not being
standards and so not wanting to use it. I told him how I do what
he's doing (with Prototype) and asked in what way he thought `target`
wasn't standard. He answered me.

Hardly a digression worth commenting on.

Sometimes discussions do start out related to Prototype and then
branch a bit into general web development (much more than this one
did), which I don't see as using the list incorrectly at all. A
question that didn't involve Prototype or scripty *at all* would be
off-topic.

  Hi.

  and each browser resulted in a different outcome (Chrome:new tab OK,

  I know that target is a no-no for standards (and it seems IE is the
  only one obeying it this time around!).

  So.

  How do I do this? The real url is supplied at runtime via an AJAX

  I could just style the a as a button ... is that possible?

  Any suggestions?

Re: [Proto-Scripty] Re: Appending a template evaluation to an HTML element.

2010-08-17 Thread Richard Quadling
On 17 August 2010 16:34, T.J. Crowder t...@crowdersoftware.com wrote:
 Hi,

 The original code:

 $('vsNewUsers').update($('vsNewUsers').innerHTML +
 tmpl_NewUser.evaluate({NewUserID : --i_NewUserID}));

 ...will require the browser to spin through the tree inside vsNewUsers
 and create an equivalent HTML string to give you; then tear down that
 tree, parse the HTML you give it back (including re-parsing the stuff
 it just gave you), re-instantiate a lot of elements that look exactly
 the same as the previous one (plus the new ones at the end), re-
 calculate the layout of the previous elements (and then the additional
 ones), etc. (Layout can be expensive with tables, too, so...)

 Seems like unnecessary work. :-) Granted the browser's going to do it
 really fast, but still. Also, you'd lose any event handlers you'd
 hooked up to the elements in there and any other data you may have
 stored on them. If your user is using IE, any elements that
 Prototype's already extended will have to be re-extended (which takes
 non-trivial time on big tables).

 Fortunately, Element#insert[1] is for exactly this situation:

 $('vsNewUsers').insert({
    bottom: tmpl_NewUser.evaluate({NewUserID : --i_NewUserID})
 });

 [1] http://api.prototypejs.org/dom/element/insert/

 Vis-a-vis using `new Element` rather than HTML: Parsing HTML and
 showing the result on the page is fundamentally what browsers do, and
 they do it really, _really_ fast. When rendering HTML, they can work
 directly with their internal structures. When you use the DOM API, you
 lose that benefit and have to work through the browser's DOM API -
 internal structures mapping. And you're doing all of your work in an
 interpreted (or at least compiled-on-the-fly) language.

 Net result? Markedly slower -- like an order of magnitude -- to go
 through the DOM API vs. using HTML. This isn't a Prototype thing at
 all, it's just the nature of browsers and what they're optimized for.
 I actually did a test page (not much of one) a little over a year back
 when answering a question for someone that showed this in action, and
 through the wonder that is 'net search:

 Does it make sense to anyone what I am trying to do?  Is there a way
 for me to do what I would like?

 I am trying to make changes to the first tr with the class sd_type
 above the current tr (in this case tr#part-47).

 Any help would be awesome.

[Proto-Scripty] Re: Weird Select list behavior in IE7

2010-08-17 Thread Nicholas
Hi all,

I have solved my issue by by using:

this.select.options[i] = new Option(opt.value, opt.key, null,
false);

rather than

this.select.insert({'bottom': new Element('option',
{'value':opt.key}).update(opt.value)});

Thanks to everyone who gave this some thought!

(Sorry for the top post)

 Hi all,

 I have a site that i need to make work in IE7 but i have run into a
 very frustrating issue.

 I am using django to generate the form for a payment request. As a
 part of this form the user can input one or more breakdowns for this
 payment, Because I only want to write the form once I duplicate the
 breakdown using element.clone() and then clean it up before creating a
 new form. I have this all working quite nicely. The issue I'm having
 is when I combine this behavior with some code I have to allow the
 filtering of select lists.

 The issue occurs in IE7 and IE8 when rendering as IE7. It does not
 occur in any other browser I have tested.

 Here is an example:

 http://www.lccare.org.au/~nsteicke/selectissue/

 To replicate, use IE7 or IE8 in IE7 compatibly mode, then click '+ Add
 Breakdown' and then filter the new select list and try and expand the
 list.

 Any assistance you can offer in solving this issue would be great.
