why does javascript lie?

patrick99...@gmail.com (patrick) — Wed, 11 Nov 2009 03:47:20 UT

Ok, this is really annoying me... When you make changes to form
elements, and refresh the page, they don't go back to their defaults
regardless of what the html says "selected" is... My plan was to have
prototype set my form elements to their selected value when the page
loads, however when I implemented this, it did not work... I could

Thanks for that Joe,

Not sure what was happening with JsUnit, as every time I created tests
and then included prototype.js, all the previously successful tests
that were passing, and were not prototype dependant failed.

Anyway think I will take your suggestion and try out the YUI framework
and see how it goes.

We use JsUnit with prototype successfully. Could you post any
additional info about the errors you are getting? What version of
prototype/jsunit/browser are you using? I will say that JsUnit seems
to be basically on life support so you might want to look in to
something else. I've recently been looking in to the YUI Test library

JSON - which chars not accepted?

mrebenti...@comparat.de (Manfred Rebentisch) — Tue, 10 Nov 2009 21:31:26 UT

I have a question to this prototype function:
function isJSON() {
var str = this;
if (str.blank()) return false;
str = this.replace(/\\./g, '@').replace(/"[^"\\\n\r]*"/g, '');
return (/^[,:{}\[\]0-9.\-+Eaeflnr-u \n\r\t]*$/).test(str);
}
If I send a JSON { 'str': '<p>This is a line with \n linefeed</p>' } I do get

Re: Stupid me cannot make Ajax.Request work

Thanks.

For anyone else searching for answers to this kind of issue, "same
port" means I can't load my test page via http and then make an
Ajax.Request via https (or vice versa). On thinking about it, of
course, this makes perfect sense from a security standpoint

Pity I was hung up on "it's the same domain" and so didn't even think

Prototype Unit Testing Framworks

d...@spidertracks.co.nz (Daff) — Tue, 10 Nov 2009 19:51:43 UT

Hi All,
I have been trying to find a Javascript Unit testing framework that
works with Prototype. I initially tried JsUnit, but it would appear that
there is a namespace conflict with the asserts, because as soon as I
include the prototype file, all the previously passing test fail, with
errors.

Re: Does $A('.classname').invoke('setValue',...) work on checkboxes?

wilkola...@gmail.com (Szymon Wilkołazki) — Tue, 10 Nov 2009 17:30:49 UT

Hi,
I found where is the problem.
I assumed, that the Form.Element.setValue method sets the value of an
element.
In case of checkboxes that is not true.
The method changes the state of checked/unchecked instead, and leaves
the value attribute unchanged.
The example might be found here:

Re: [Proto-Scripty] Re: PeriodicalExecuter that doesn't stack

webmas...@thecarmarketplace.com (Alex McAuley) — Tue, 10 Nov 2009 16:42:54 UT

It makes the call asynchronous (it will only do one thing at a time) .. so if you had a stack of 8 ajax calls it would go through them one by one in synchronous fashion until they are done...

If you have other ajax calls going on in the page from different functions - this one would sit in the stack until the interpreter is ready and execute then (AFAIK)

If I turn off async will that only block on that one call or will it
block
other calls from happening also?

webmas...@thecarmarketplace.com (Alex McAuley) — Tue, 10 Nov 2009 15:27:44 UT

To stop the stacking just use asynchronous flag and set it to false...

Though it does go against the AJAX it will work...

Perhaps you can get around the decay/frequency with somehting else

Sorting and z-index problem

dave.lemanow...@gmail.com (dl) — Tue, 10 Nov 2009 15:02:19 UT

I'm using scriptaculous to make page elements resortable through
dragging and I'm running into a problem with z-index and the YUI split
button. I know it could be difficult to say of the problem is with
the YUI code or scriptaculous code but I think it's scriptaculous code
(or my use of it) and the YUI widgets just make the problem visible.

This will call a function and not a url ?
new Ajax.PeriodicalUpdater(contain er, url[, options])
stacking: ie multiple request will stack on top of each other whether
or not the previous one
has completed or not.
If this is making a request say every second there is the possibility
that the request may not finish in time before the

You have answered your own question...

In your original post you said that you could fix the problem if you could
get Periodical to "call a function instead of a url" .. and what i suggested
does just that ...

I am not sure i understand what you mean by stacking

As for frequency: you dont need to worry about it if you are usig periodical

willi...@rebelfactions.com (William Taylor) — Tue, 10 Nov 2009 14:06:11 UT

wow I must have been tired when I wrote that.
I said PeriodicalExecuter but I really meant Ajax.PeriodicalUpdater

So ya is there a way to make Ajax.PeriodicalUpdater not stack and to
possibly give it
a maximum frequency limit?

Does $A('.classname').invoke('setValue',...) work on checkboxes?

wilkola...@gmail.com (Szymon Wilkołazki) — Tue, 10 Nov 2009 12:54:39 UT

Hi,
I just bumped into a weird bug in my code.
The thing is, that I am trying to update value of several checkboxes
with a value received in a result of ajax call.
Anyway, I have following construction:
<input name="someName" class="APP_CHANGELOG_LOG_ID" value=""
type="checkbox"/>
The checkboxes are unchecked by default.
