Re: [Proto-Scripty] Re: Passing the content of an array in a form
Le mardi 22 décembre 2009 05:11, joe t. a écrit : For most typical cases, JSON is easier, and more efficient. For one, by sending a Content-type header of application/json you can send an array down from the server, and Prototype automatically converts it into a JSON object you can utilize. I'm switching to json, and you're right, it is much easier to handle! -- Frédéric -- You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

Re: [Proto-Scripty] Re: Prototype and IE
Hi,
i get the problem, it was a span with some attributes that was inserted in a
hiperlink the code that generated the non-show elementos on links was:
a onclick='site.linkClick(/, home); return false;' href=#
class=link-homespan style=display: block; visibility: hidden;//a
the span block that caused the problem in IE.
Thanks for the insights.

Hi,
I'm afraid there's nothing much to do other than step through it in a
debugger (yes, there _are_ debuggers for IE, the script debugger[1]
and Visual Studio) and figure out at what point it's breaking. If you
can figure out where it's breaking and post that, we may be able to
help.

Hi T.J. Crowder
ajax-content is the only ID for the content element.
I am working with Prototype Version: 1.6.0.3 i will read and alter to
the
proper usage of Class.create.
Ps.: ProtoHistoryManager is from one extension that i get in
http://scripteka.com/(Prototype.HistoryManager)http://scripteka.com/%28Prototype.HistoryManager%29
Thanks
2009/12/21 T.J. Crowder t...@crowdersoftware.com
Hi,
I can't address the ProtoHistoryManager stuff, never seen that. But
the `getPage` call looks fine.
IE has issues with confusing IDs and names; do you have *anything*
else on your page with the ID _or_ name ajax-content?
[Possibly OT] What version of Prototype are you using? Because your
Class.create call doesn't look like it's for the current version of
Prototype (1.6.1). Since 1.6.0, you shouldn't replace the prototype
on
a class you've created with 1.6.x's Class.create. More:

Re: [Proto-Scripty] Re: Ajax.Request
If i recall correctly ...
Failure only gets called on a server error ... like a 404 ...
The failure may be due to a javascript error and would not return the alert
if that was the case.
On the back success only calls when the server has responded...
Ergo there are many things that can go wrong - i've listed a couple below
1. Transit. To/From the server
2. Server side scripts (will return whitespace upon an error - if error
reporting is turned off) and this is still considered a success by
javascript.
Also i noticed in the original post that you had asynchronous: true...
It is true by default so you can save a few bites there.
As TJ said in an earlier reply, You cannot return out of the Ajax request as
it is run asyncronously with the page (meaning [in easy terms] you can
execute alot of javascript at the same time as the request without locking
the browser]). To perform what you want to achieve (if i'm getting what you
want to do correctly) you should create a response handler ... something
akin to
onSuccess : function(data) {
myHandler({data:data.responseText.evalJSON,vars:someotherVars});
}
...
function myHandler(options) {
var ReposnseData=options.data;
$('someElement').update(ResponseData);
}
Hope this helps...

Re: [Proto-Scripty] Re: Ajax.Request
An alternative i sometimes use is to set a timeout on a function to check within a period of time - usually a hidden input with the time of the request - checking it until its complete That way i can know if anyting failed in the request and send it again if it did ... each to their own !

[Proto-Scripty] Re: self-or-ancestor in one whack?
You could use a closure to ensure you're dealing with the right
element.
$$('.my_table td').each(function(cell){
cell.observe('mouseover', listener.curry(cell));
});
function listener(cell, evt){
if(evt.element() != cell)
return false;
}
Are you trying to have a clean way to avoid flickering?

Sort of, really just trying to make sure that mouseover events
triggered by child elements are credited to the parent. I tried
Tobie's technique, and it works perfectly. My long-hand method worked
fine as well -- no flickering I could discern -- so it's really just a
coding elegance refinement I was going for rather than anything else.
I am using event delegation -- observing the entire table once rather
than each cell -- so maybe that's why I wasn't seeing any flicker.

Hi Loris,
I think that your trouble is normal, because IE don't allow to

Generally it's not a good idea to extend native objects because your
