[Proto-Scripty] Re: Help destroying many events on tr mouseenter and mouseleave
I've been in a similar situation, where I had a list of search results which were updated on every key press (but at most once every 100ms), and I wanted each row in the results table to have mouse-hover effects. My solution was to attach an event handler only to the table, and then wait until the on mouse move event to work out which element the mouse was over by using Event.element(event). This means that you don't need to attach or detach any event handlers, since there is always just the one on the table itself.

Re: [Proto-Scripty] Re: click one checkbox will submit only one checkbox value (not the whole form) immediately
Well, this has nothing to do with prototype, but you might use
Prototype's Ajax.Request[1] to send only the data from the checked
input (as follow):
e.g.:
form name=myform method=post
input type=checkbox name=choice value=1 onclick=myMubmit(this);
input type=checkbox name=choice value=2 onclick=myMubmit(this);
input type=checkbox name=choice value=3 onclick=myMubmit(this);
/form
function myMubmit(input) {
new Ajax.Request(url, {
method: 'post',
parameters: input.name +'='+input.value,
onSuccess: function(r) {
// show the result or do something wild
}
});
}
You can also use Prototype's Event.observe[2] to check the click event
on each checkbox.

In your case, the name is too inconsistent, you could have almost
gotten away with $$(input[name~=opt) but alas there is no space

As an alternative, looking at your code you just do... $$(input

A *much* better approach is to use an event, and Prototype provides

document.observe('dom:loaded', function () {

[Proto-Scripty] Re: Ajax response encoding type changing depending on windows (UTF-8) vs unix (ISO-8859-1)
Prototype has _nothing_ to do with the response code.
Your backend is sending the wrong encoding. Problably, you have not
set the correct send headers.
Are you using a PHP backend? If yes, maybe your local php.ini have
default_charset set to utf-8 and the unix one has not, by default, php
uses iso-8859-1.
Try adding this line to you response:
header('content-type:text/plain; charset=utf-8'); // of course, the
content-type you are expecting
or use [1]utf8_encode(CONTENT) before send the response.

[Proto-Scripty] Clarification on PUT method in Ajax.Request
The documentation on Ajax.Request, for the method option, says: method 'post' The HTTP method to use for the request. The other widespread possibility is 'get'. As a Ruby On Rails special, Prototype also reacts to other verbs (such as 'put' and 'delete' by actually using 'post' and putting an extra '_method' parameter with the originally requested method in there.

[Proto-Scripty] Re: Adding properties to native objects
T.J. is correct, of course, that my original suggestion would make
multiple copies of the functions. That's what I get for writing off
the top of my head. If I understand correctly, what joe t. really
want is something like:
!DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Transitional//EN
http://www.w3.org/TR/html4/loose.dtd;
html
head
meta http-equiv=Content-Type content=text/html; charset=UTF-8
titleSpecialDate/title
script
var specialDateFactory = function () {
var calcIsEaster = function () {
// do something with _this_, which will be a Date object
this.isEaster = true; // replace with real code
}
var calcIsLaborDay = function () {
// do something with _this_, which will be a Date object
this.isLaborDay = false; // replace with real code
}
return function () {
var that = new Date();
that.calcIsEaster = calcIsEaster;
that.calcIsEaster();
that.calcIsLaborDay = calcIsLaborDay;
that.calcIsLaborDay();
return that;
}
} ();
/script
/head
body
script
var myDate = specialDateFactory();
document.write(pmyDate.isEaster: + myDate.isEaster + /p);
document.write(pmyDate.calcIsLaborDay: + myDate.calcIsLaborDay +
/p);
document.write(pmyDate instanceof Date: + (myDate instanceof
Date) + /p);
/script
/body
/html
The factory function specialDateFactory returns a Date instance which
has methods calcIsEaster and calcIsLaborDay, and properties isEaster
and isLaborDay. If you change the value of the returned object, you
can call calcEaster and calcIsLaborDay again to refresh .isEaster
and .isLaborDay.
What's more, the functions like calcIsEaster and calcIsLaborDay can
call each other securely -- no matter how objects returned from
specialDateFactory are abused, variables in the closure are
undisturbed. So you can securely add lookup tables and helper
functions hidden from the outside.
And this introduces only one closure, so it's fairly cheap.
JavaScript constructors are an anomalous, pseudo-classical things.
If you're not going to compare objects with instanceof, don't bother
with them. More often, factories are what you really want.

[Proto-Scripty] Re: Adding properties to native objects
You may want to use Crockford's factory pattern, rather than using any
sort of constructor:
function specialDateFactory() {
var that = new Date();
that.isEaster = function () {return ...},
that.isLaborDay = function () {return ...},
return that;
}
You can get more sophisticated - creating a prototype object for
special dates, with the functions defined on it, and using closures to
protect it, but I can't write that off the top of my head...

Fair comment. But you are still talking about using Javascript's

[Proto-Scripty] Re: Recommended and Disrecommended DOM Methods
I suppose compiling a list would be a useful exercise, and I can post it on the wiki for other newbies. On Apr 18, 5:56 am, T.J. Crowder t...@crowdersoftware.com wrote: Hi, I don't think there's a list quite like what you're asking about, no, but if you have a read through the API docs[1] and in particular the docs for Element[2], that will give you a pretty good idea of what you can do with Prototype vs. what you'll need to go direct for.

[Proto-Scripty] Re: Client-side File Processing
I created the following HTML file to test your function and get the
following errors:
1) The file input element returns only the file's name, so I don't
see how your function could load the file in.
2) Under Safari 3 and later, I get a TypeError: Result of expression
'xmlDoc.load' [undefined] is not a function. when your function
attempts to call xmlDoc.load()
3) Your function always returns null, under Firefox 3.0.8 and Safari 4
beta, presumably because it only has a file name, not the file path.
It does appear to work under Opera 9.51. [all under OS X 10.5.6]

I'd like to allow the user to select a file from his/her filesystem,

semblance thereof) the value of a file input element is just the name
of the file, not the full path, in many modern browsers, so the file
path can't be turned into a file: URL that can be loaded via AJAX.
Is there a way to access the contents of the file using Prototype?
Nothing to do with AJAX (where AJAX is a pseudonym for
xmlHttpRequest). If it's an XML document, it can be loaded using a
fairly simple script:

[Proto-Scripty] Re: Prototype IE 7 error
I could not access any .js file there. You might check out the given permissions.

I just got an email from an user of my webservice that the drag'n drop function doesn't work anymore. Sadly, he's using the internet explorer 7 and 8beta, and as I'm running on a Mac, I can't say how long this problem persists. The ie debug-tool says (translated from german, could be expressed otherwise in english): 'Droppables' is undefined and 'Draggables' is undefined And thats the point. It works fine with Opera, Safari, Firefox... Even epiphany and konqueror have no problems with this simple drag'n drop thing. I can't say anything about IE6, because there are less than 2 % using it on my website. If you need to see the website, go on, i created a demo-account: www.ld-host.de/login User: Demo Password: demo Navigate to Bilderverwaltung or www.ld-host.de/editfolder/0 and try to drag an image from the right side to a folder on the left side (Unsortiert, Einer zu viel, ...) I hope you guys could tell me a solution.
