Have you ever considered not including the initialize method in the
subclass?
Perhaps your baseclass can check if there's a child 'constructor' present
and automatically call that:
var MySuper = Class.create({
initialize: function() {
// do stuff
if (this.childConstructor) {
this.childConstructor();
}
}
});
var MySub = Class.create(MySuper, {
childConstructor: function() {
// stuff that only the child needs to do
// MySuper.initialize has already been called at this moment.
}
});
Ofcourse the naming can be different but it's just an idea.

Hi there!
I found a very useful script-snippet for endless scrolling. It loads
new content via AJAX when the page is near the bottom of the page. My
knowledge about JavaScript and Prototype is pretty good actually, but
I always had problems with all the measurement stuff.
Here's the line of code:

How could I get that working with Prototype?

[Proto-Scripty] Future of Prototyp.js
The rapid development of browser features they caught up and there are fewer and fewer differences between them. A year later, they practically do not remain. IE6 is already innonexistence. So I think that the new version should be completely rewritten, freed from the burden of supporting non-existent differences and older browsers and their versions, to be compact andincorporate only what is necessary for developers. Look at script.aculo.us - its now Scripty2 full rewritten library, compact and modern! If the library becomes of such - it can easily be used on mobile devices will become more widelypopular.

[Proto-Scripty] An idea from jQuery which might be borrowed to Prototype
Hi! Working on porting Microsoft DataLink plugin to Prototype i began learn jQuery and found one interesting thing; instead of workin whith JS objects in the way of Object.method(obj) they use wrap this object in so called jQuery object which already has all needed method and propeties to work with the object but keep original object inside untouched. This has a benefit - original object is untouched and we can work wit it like it has everithing we need. And there is the second benefit - the wrap object has internal id !!! - so it can use storage like DOM element in Prototype.js but I cannot! -- You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

[Proto-Scripty] strange problem with detect method and cloning data
I have a class
var a = Class.Create({
function initialize() {
var _items = [];
Object.defineProperties(this, {
'items': {
get: function () {
return Object.clone(_items);
},
enumerable: true
}
});
...
}
function indexOf(item) {
return -1;
}
});
then I create an instance of the class
var b = new a();
then I fill the _items with the data
[
{ name: 'Joe', last: 'Celko' },
{ name: 'Ivan', last: 'Susanin' }
]
and ovewrite the indexOf method with thw new one
b.indexOf = function(item) {
var index = -1;
var items = this.items;
items.detect(function(el, idx) {
var b = (el.name === item.name) (el.last === item.last);
b (index = idx);
return b;
});
return index;
};
then i try to seach
b.indexOf({ name: 'Joe', last: 'Celko' });
and always get -1 !!!
I try to debug and detect the this._each in Enumerable.each never goes
into, but if I chnge
return Object.clone(_items); --- return _items;
everything goes ok and returns 0! Why?
Help me please. I cannot expose original items because changes on it
maybe damaged

I think this is a fair-ish (but incomplete) summary: 1. Prototype is a spare-time activity for a very small number of people. In fact, at the moment I think it's mostly just Andrew, and he has other things he does (like, you know, hold down a full-time job). Just recently the project largely lost another major contributor to his job and family commitments. 2. Andrew has no plans to stop working on Prototype on any time soon. 3. Prototype work is done in fits and spurts, long periods of inactivity followed by a period (couple of weeks) of feverish activity. 4. jQuery has multiple corporate sponsors, not least Microsoft, and there are people paid to work on it full time. Thus it's able to be much more up-to-date and proactive than Prototype.

It is certainly the _de facto_ JavaScript library for web development. The good news is that the losers of the war aren't looking so bad; libraries like Prototype, MooTools, and Dojo still have loyal user bases, and I doubt they're going away. My personal perspective, for what it's worth (e.g., possibly exactly what you're paying for it, nothing :-) ) is based on some data points: 1. The last blog post on the Prototype blog was 10 months ago. 2. The library has had basically no activity since v1.7 was released November 2010. 3. The most recent three releases were: š šv1.7 - November 2010 š šv1.6.1 - September 2009 š šv1.6.0.3 - September 2008 Three releases, in total, including dot releases, in the last three years. Compare with 16 releases (four major ones) of jQuery in that time period (v1.3 through v1.6.4). 4. Absolute use and trends: Absolute use:http://trends.builtwith.com/javascript Prototype trend:http://trends.builtwith.com/javascript/Prototype jQuery trend:http://trends.builtwith.com/javascript/JQuery 5.

Does all this mean Prototype is dead? No, not a bit of it. But it has a very small staff with other major demands on their time, and has no funding. Andrew's quite clear that it's not dead, and also that it will continue in much the way it has these last three years.

[Proto-Scripty] Re: Future of Prototype.js
questions, but for me the business case is: Which library amongst the large number out there is kept up-to- date; jumps on testing new browser versions for compatibility; has a large ecosystem of code I can use; has a large pool of talent I can hire or contract; has well-maintained, frequently updated and extended, reliable, and documented UI helpers (jQueryUI vs. Script.aculo.us); and is likely to be around long-term without heroic effort from a single individual, or a small set of individuals. So I went with jQuery, despite preferring Prototype in many ways. [I also looked at Dojo, ExtJS, (more recently) Closure, and a few others.] It could have gone another way. People like me could have done more to contribute to the project; leadership could have focussed on core functionality, community-building, and developer (um) development rather than side-issues; corporate sponsorship could have been courted and perhaps ultimately found. But that didn't happen, and it didn't happen because the Prototype community and leadership didn't make it happen (perhaps corporate sponsorship wasn't desirable; fair 'nuff) and because luck didn't go Prototype's way. (And don't think luck isn't a big factor here.) I have nothing but respect and admiration for Andrew and everyone else who has made Prototype what it is. And there's absolutely no reason not to use it on your websites if you test with your target browsers and it does what you need it to do. Again, Andrew is clear he'll keep going with it, and I'm sure he'd be very happy to have help from anyone reading this. So does Prototype have a future? Yes. What kind of future depends a lot on the people reading this note. If you all, like me, don't have time to contribute and Andrew has to largely work on his own, that's one kind of future. If you can make time to help, get your companies to let you help a bit during paid time, that sort of thing, then it will have a different kind of future. I hope all these recent questions about Prototype's future mark the beginning of a renaissance for the library, a turning point of talent looking to help out. I wish I could be part of it.

[Proto-Scripty] The method of the temporary opening and closing access to the private variable.
I've found an article in russian A modular approach to
JavaScript. (http://habrahabr.ru/blogs/javascript/117069/)
where the autor explains one interesting idea how temporary to open/
close acces to private variable.
This trick is based on that if private variable is not simple tipy -
it may be accessible through a reference outside the private scope
var MODULE = (function (my) {
var
_private = my._private = my._private || {},
_seal = my._seal = my._seal || function () {
delete my._private;
delete my._seal;
delete my._unseal;
},
_unseal = my._unseal = my._unseal || function () {
my._private = _private;
my._seal = _seal;
my._unseal = _unseal;
};
// permanent access to _private, _seal, and _unseal
return my;
}(MODULE || {}));
It's useful when MODULE is broken down into files.
To give an acces to part of MODULE in anothe file:
MODULE._unseal();
do somthing with MODULE._private (e.g. with _private)
MODULE._seal();
It's very interesting!

No, that's a very inefficient way to call them. Instead:
_privateFunction.call(this, arg1, arg2);
or
_privateFunction.apply(this, array_of_args);
Function#call and Function#apply are part of JavaScript. More about
them in the spec[1], of course, and on MDC[2][3].
More about various approaches to private methods here[4] and (somewhat
indirectly) here[5].

[Proto-Scripty] Is there a way to autoinherited static member from superclass

var Class2 = Class.create(Class1, {

Is there a way to inheritate staticProp and staticMeth in inherited

Not built into `Class.create`, no. You could readily create a wrapper
for it that did that, though, looping through the own properties on
the superclass passed in and applying them to the resulting subclass
function. Important to be sure to skip over some that shouldn't be
copied, like -- to pick an example at random -- `prototype` (though I
don't think `prototype` is an enumerable property anyway, so it
shouldn't show up on a `for..in` loop). But there will be some to
skip, not least the ones Prototype puts on it like `addMethods`,
`superclass`, etc.

`Class.create` *does* create methods on the prototype:
var C = Class.create({
foo: function() {
}
});
display(typeof C.prototype.foo == + typeof C.prototype.foo);
// typeof C.prototype.foo == function
Live copy:http://jsbin.com/ajifi5
Do you mean static methods? E.g., C.methodName? `Class.create` doesn't
do them, but they're easy to add either directly or via
`Object.extend`:
Object.extend(C, {
bar: function() {
}
});
display(typeof C.bar == + typeof C.bar);
// typeof C.bar == function
Live example:http://jsbin.com/ajifi5/2
(Side note: I'm using anonymous functions above, which I don't
actually like very much.[1] But I didn't want to introduce scoping
functions and such.)

On 22 ноя, 12:15, T.J. Crowder t...@crowdersoftware.com wrote:
I have two calls run asyncronously
Two - is an example - they may be N-calls :)
I'd recommend avoiding that unless the async calls are to *different*
servers, and if you do two at once, certainly never do more than two
at once. Run just a single async request at a time, two if you
absolutely have to, and chain them using the `success` handler.
Why? Because browsers (and some servers) clamp down the number of
connections to a given server at the same time. Mostly, with modern
desktop browsers, you can expect the browser will allow four[1] (up
from the previous figure of two), but IE will drop down to only
allowing two if it detects a dial-up connection and you don't know
what the next dot rev of any browser may do. Also, mobile browsers
have lower limits.
In terms of mechanism, I'd probably have a pending count (no need for
global variables):
* * * *
// Start the requests defined in the array `requests`, call `callback`
// when they've all finished.
function sendMultipleRequests(requests, callback) {
var req, pending;
// Prep and start each request. We assume the objects have a `url`
// property and a `params` property.
pending = 0;
while (pending requests.length) {
// Get this request
req = requests[pending];
// Hook into the onComplete, respecting the previous one if
any
req.params = req.params || {};
req.params.onComplete = req.params.onComplete
? req.params.onComplete.wrap(reqComplete)
: reqComplete;
// Start and count this request
new Ajax.Request(req.url, req.params);
++pending;
}
function reqComplete() {
--pending;
if (pending = 0) {
// All done, call the callback.
// Note that there's no race condition with the loop above
(e.g.,
// there's no possibility we'll be called and decrement
`pending`
// to 0 while the loop above is still incrementing it)
because
// JavaScript on browsers is single-threaded unless you
explicitly
// use the web workers stuff, which we aren't.
callback();
}
}

Subject: Re: [Proto-Scripty] Do somthing only after two Ajax calls return

Hi Buda,
Having had this issue, and seen other frameworks sorting this out, the
quickest and easiest way I have found is to have to global variables (flags)
in the page, one for each of the Ajax calls.
The Ajax callback method for each then sets the flag for that call back,
then checks if both flags have been set, and if so, calls the function of
your choice that will then continue the processing you desire.
Because each callback only sets its own flag, but then checks both, it will
not matter which order they callbacks are received and processed.
pseudo code (untested)
var flag_1 = false;
var flag_2 = false;
function callback_function_1() {
// Processing...
flag_1 = true;
if(flag_1 flag_2) {
// Call final method...
finalize()
}
}
function callback_function_2() {
// Processing...
flag_2 = true;
if(flag_1 flag_2) {
// Call final method...
finalize()
}
}
function finalize () {
// Complete processing here...
// If we need to call again, then reset the two flags in here...
}
Hope that helps.
Regards.

However, I'm currently working on a project where you can create simple webpages by adding different types of paragraphs, (eg. Text, Image, Video) one below the other, and edit their contents, move or delete them. Basically like this: http://blogage.de/files/60901/image Im rewriting the JS and I have a little problem here; I recently read that extending the DOM is basically a bad idea and that in Prototype 2 they will even stop that practice. Now my idea (actually) was, for a project like this, to create classes for each paragraph-type with methods and properties that I would extend the paragraph-DOM with. I mean that if I had, like in the above image, three paragraphs, each would be represented by a DIV with the class=paragraph text or class=paragraph video etc. On the JS-side there would be classes like Text or Video which would have a method that would extend those DIVs with functions and properties necessary to edit, move or delete that paragraph. When, for example, the user clicks on an editlink, it simply would call its paragraph's edit-method. Everything would be nice and clean. But now I know, extending is bad. So I'm kinda stuck here, I don't know how to write unobtrusive JS without writing terrible spaghetti- esque code with lots of observers. I mean I could still organize parts of the code in classes, but there would be a long list of observers (eg. for clicking an edit-link) with switch-cases for the types of paragraphs. Actually even with extending the DOM I'm not totally sure how I would catch the edit-clicking event. As I said, I'm kind of stuck :). Can you help me with ideas? How would you do this?

Hi,

No, properties and attributes are very different things, as I said.
You have to be cautious when using expandos, and if you're using
Prototype there's not much reason to (use the storage stuff instead),
but they're not bad per se.
...but I see expando on extended elements in prototype!
Prototype's use of expandos is mostly reasonably cautious. (Could be
more so, but...) For instance, all non-API expandos start with an
underscore, which means they are very unlikely to conflict with
official properties in the future. (For example, when you use
`makePositioned` on an element, there's an expando set on the element
instance called `_madePositioned`. It's very unlikely that there will
be an official or browser-specific property called `_madePositioned`
in the future that will conflict with Prototype's expando.) And I'm
reasonably certain they never use an expando to refer to another DOM
element or to a JavaScript object that, in turn, refers to another DOM
object.
I said non-API expandos because, of course, all of the stuff
Prototype adds to element instances (`addClassName`, `up`, `down`,
`select`, etc.) are expandos. On browsers that allow it, they're added
to the element prototype, but on IE (and theoretically other browsers
that don't allow it), they're straight expandos added when the element
instance is extended. And sure enough, that's been a problem at times
in the past, when there was some browser-specific extension that
conflicted with a name that Prototype was trying to use for something
else. (I don't have a specific example, seem to recall some problem
using `Element#select` on certain elements in Safari or something.) I
understand a future version of Prototype will switch to using element
wrappers rather than directly extending the elements (I'm guessing
it'll be 2.0, that's a big enough change to justify bumping the major
rev.)
In your question you said you wanted to be able to use the things
you're setting on the element in a selector:
$$('p[myAttr=foo]')
...and so in your case, you'll need to use a custom attribute. The
best way to use a custom attribute is to use the data- prefix:
p data-myAttr=foo.../p
$$('p[data-myAttr=foo]')
If you also have cases where you don't need it as an attribute, either
use an expando *cautiously* or -- and this is probably better -- use
the storage system (`Element#getStroage`) that Prototype provides.

Hi,

Yes, I think you are. Easy enough to do, but they're really quite
distinct things.
HTML elements have attributes, which (initially) come from the markup
and are accessible via the DOM methods `getAttribute` and
`setAttribute` (Prototype provides `readAttribute` and
`writeAttribute` that you should use instead, as they fix lots of
oddities -- particularly in IE -- related to certain attributes.)
Attributes are not properties.
JavaScript objects have properties. The objects browsers provide to
JavaScript to represent the DOM are sufficiently like JavaScript
objects that they also have properties. (This needn't necessarily have
been the case, host-provided objects can follow just about any rules
they want, but in practice -- fortunately -- even IE made it possible
for the objects themselves to have JavaScript-like properties.)
Some attributes are _reflected_ as properties. The classic example is
the class attribute, which is reflected by the `className` property.
Setting the attribute changes the property; setting the property
changes the attribute. But not *all* attributes are reflected as
properties, and not all properties reflect attributes.
People sometimes add their own custom properties to DOM objects.
That's what we call expando properties. These are not attributes.
Technically (again) it would be possible that a browser would not
allow custom properties on the DOM objects it provides, but
fortunately (again) none of the major browsers has a problem with it.
And so we can do things like this:
š š var div = $('mydiv');
š š div.foo = bar;
...and later we can refer to `$('mydiv').foo` and get back the string
bar. This is very convenient, but you need to be careful with it,
especially on IE

...and later we can refer to `$('mydiv').foo` and get back the string
bar. This is very convenient, but you need to be careful with it,
especially on IE. Firstly, you need to be sure you're not using a
property name that the browser is already using for something else!
Secondly, you need to be sure that you don't create circular
references between DOM elements and JavaScript objects when you do
that, because that causes memory leaks on IE. That's why libraries
like Prototype provide a means of storing metadata on elements via
their APIs (I think on Prototype it's `Element#getStorage`), so they
can take care to avoid issues for you.
People sometimes add their own *attributes* to HTML elements, usually
in the markup to associate further information with the element. For
instance, recently I ran into someone who put all of the weights on a
page into spans so that users could easily toggle between pounds and
kilos in the display using JavaScript, but he couldn't figure out how
to do it. I suggested using a custom attribute to hold the canonical
weight (what they have in their database) and then toggling the
content of the span based on what the user prefers. For 15 years,
custom attributes on HTML elements in the markup have been *invalid*
-- they would not pass the validation suites that people use to check
their markup. The HTML5 working group recognized the value of custom
attributes, but also the danger in people just defining things willy-
nilly, and so they defined the data- prefix. You can't have your own
weight attribute, but you can have your own data-weight attribute.
I use custom attributes (*always* with the data- prefix) for
conveying information in the markup that I later want to access from
script, like the data-weight attribute above. I also use them if I
need to be able to search for elements that have a certain piece of
information on them. For instance, in the weights example, it's
trivial to find the spans we need to change when the user changes the
display from kgs to lbs:
$$('span[data-weight]').each(...);
If we used an expando property that we added to the elements after
page load, we wouldn't be able to use that selector.
I use expando properties (or data storage via an API) when I need to
associate information with an element that I don't need to convey via
markup or search for later with a selector. This is just to cut out
the overhead of reading and writing attributes to the underlying DOM,
and because properties can be things other than strings. In practice,
I find I have virtually no use for expando properties in my
applications (I use elements to *represent* application objects, not
*as* application objects), but they're frequently useful in library
code.
Hopefully that rambling was of some use. :-)
Happy coding,

What you're saying you need doesn't make sense in terms of the DOM's
event mechanism. Basically, you want the standard observer pattern.
That's why Mona pointed you at an alternative means of dispatching
events that isn't tied to the DOM's concept of how they should work.

[Proto-Scripty] Why element never receives an event?
On the form form1 is an element MyElement
I attach to MyElement event handler
MyElement.observe ( 'form: updated', function (e ){...});
then in the code generating the event
form1.fire ( 'form: updated');
but the handler is not called for MyElement
Why?

Hi,
Events bubble *up* through the DOM, not down. Form elements are
descendants of forms. If you fired the event on the form element, the
form could see it; but not the other way around.

The main advantage of the emptyFunction is that you can always call it
without having to do a null/undefined test first.
If you want to know if it has been assigned something, then don't
assign the emptyFunction, leave it as null and then test if it is
null.

Hi,
Just reuse the same handler for multiple events:
function handler(event) { /* ... */ }
element
.observe('change', handler)
.observe('paste', handler);
If you need to bind, do that first so you're not creating unnecessary
extra functions:
var Thingy = Class.create((function() {
function handler(event) { /* ... */ }
function hookUsUp(element) {
var boundHandler = handler.bind(this);
element
.observe('change', boundHandler)
.observe('paste', boundHandler);
}
return {hookUsUp: hookUsUp};
