[Proto-Scripty] Re: Using a prototype function in dynamic content.
Hi,
if (http_request.readyState == 4) {
if (http_request.status == 200) {
document.getElementById('load').innerHTML =
;
You're not using Ajax.Request[1] or Ajax.Updater[2]?
This is my onSuccess handler, how do
I apply evalScripts?
DJ and I are talking about a Prototye onSuccess handler for one of the
two features above.
document.getElementById(div).innerHTML = thereturn;
Your code is setting the innerHTML property directly. If you just
change that line to use Element#update instead, #update will handle
eval'ing the scripts for you:
$(div).update(thereturn);
Altenately, keep setting innerHTML directly (although #update does
some very handy things for you) and then after doing that, call
String#evalScripts() directly:
document.getElementById(div).innerHTML = thereturn;
thereturn.evalScripts();
String#evalScripts is a method Prototype adds to the String prototype
and so it's available on all strings. Details here.[4]
Looking at your quoted code, you're not making much use of Prototype
at all -- not even the $() function! (So much more compact than
document.getElementById.) I suggest taking an hour to read through
the API docs[5] front-to-back to get an idea of what's on offer. It
literally takes an hour and saves you no end of time in the long run.
May also be worth reading through some stuff on the unofficial wiki
[6].

[Proto-Scripty] IE 8 Bug
Afternoon Guys/Gals.
I have a weird error in IE8.
removeSuggestResults = function() {
$$('.editsuggestResults').each(function(el) {
$(el).remove();
});
}
Doesnt seem to work in Internet explorer 8.
The Element exists and was added dynamically to the DOM and has the
classname.
I read somewhere about IE8 not adding classnames to elements when the
classname is in the options of new Element(); so i called $
('suggestiveResults').addClassName('editsuggestResults');
to be safe. But it seems to not be working. I also cant get a copy of
firebug lite as the site seems to be down so i cant test the element
to make sure it has the class
Can anyone help ?
Thanks in advance

I had similar problems - and found out that .down() or .select() fails
when the element's id that it's fetching is starting with a number.
So, $('test').down('ul, 1) failed for me, because the ul-element's id
was something like 1_23402922. I changed it to begin with a letter
(s_1_23402922) and it worked then.

[Proto-Scripty] Autocompleter getSelectionId additional variables
Hello All,
I want to use the Ajax.Autocompleter class together with
getSelectionId in order to use the li ID of the chosen selection to
initiate further javascript actions. Anyway I would need to transfer
additional variables to the getSelectionId function. But as soon as I
try to send more variables to it, it does not work anymore:
This is more or less how it works (taken from the documentation):
new Ajax.Autocompleter('autocomplete_field', 'autocomplete_choices', '/
some/script', {
paramName: 'searchterm',
minChars: 5,
indicator: 'status_field',
afterUpdateElement : getSelectionId
});
function getSelectionId(text,li) {
alert (li.id + ' ' + 'ticketID');
}
And this is what I planned to do:
var parameter1 = 'something';
var parameter2 = 'blabla';
var parameter3 = 'anotherthing';
new Ajax.Autocompleter('autocomplete_field', 'autocomplete_choices', '/
some/script', {
paramName: 'searchterm',
minChars: 5,
indicator: 'status_field',
afterUpdateElement : getSelectionId
(text,li,parameter1,parameter2,parameter3)
});
function getSelectionId(text,li,parameter1,parameter2,parameter3) {
alert (li.id + ' ' + 'ticketID');
}
But this does not work. How can I send additional parameters to the
getSelectionId function?
Thanks in advance.
Best Regards,
Benedikt

[Proto-Scripty] Class with Ajax and onclick event
Hello,
This is my first post here. Thus, I'll like to say hello to everybody
in this community and I want to appologize if this question was asked
before.
I am a web developer for a site that has 1mil+ visitors/month: www
[dot] ziare [dot] ro, and I want to use the Prototype Framework to
make an element refresh itself (with an scriptaculous Effect)
periodically.
This is my class:
var Dynamic = Class.create({
initialize: function(selector, container, script)
{
this.selector = selector;
this.script= script;
this.container = container;
this.changeContent =
this.changeContent.bindAsEventListener(this);
this.getContent();
},
getContent: function()
{
new Ajax.Request(this.script, {
onSuccess: function(req)
{
this.content = req.responseJSON;
//document.fire('content:retrieved',
req.responseJSON);
}
});
$$(this.selector).invoke('observe', 'click',
this.changeContent.bind
(this));
},
changeContent: function(event)
{
event.preventDefault();
console.log(this.content);
console.log(this.container);
/*new Effect.Fade($(this.container), { afterFinish: function() {
new Effect.Appear($(this.container));
}
});
$(this.container).update('cucu');*/
}
});
document.observe('dom:loaded', function() {
var dyn = new Dynamic(.tzNavLink a, tzContent,
titlurileZilei.php);
});
'tzContent' is the div whose content changes by clicking on of the
links with the 'tzNavLink' css class (the 1 2 3 4 5 6 links on www.ziare.ro).
The problem is that this.content is undefined in changeContent (a
function that listens for the click event), although this.container
works well in the same function. Why is that? It has something to do
with the Ajax.Request?
Also, I want to ask how can I 'tzContent' to change periodically using
such and object (I want everything to be encapsulated so I can use
this object in other projects)?
Thank you for your response.

[Proto-Scripty] Re: Firefox v3.5
Hi,
I had similar problems - and found out that .down() or .select() fails
when the element's id that it's fetching is starting with a number.
IDs can't start with nubmbrs.[1] But Mona's bug report is for a valid
ID (containing a dot and/or colon, both of which are valid). It's
been accepted on the bug list and probably fixed by now in trunk.

I have done that change but still there is an error then,
I changed line 3339 (e = # + id + + e;) to
if (id != 0)
e = # + id + + e;
Now it seems working

Must be that you're using (dot) or (colon) in your ids.
This has been fixed, but not yet released. You can manually change in
prototype.js line:3338 to match
id = id.replace(/([\.:])/g, \\$1); // NOTE the $1 instead of $0
This fix will be a part of next release as it is in the trunk [1]

[Proto-Scripty] Re: Autocompleter getSelectionId additional variables
The Autocompleter#afterUpdateElement method only passes those two
parameters, the element that the autocompleter is attached to (input)
and the selected item from the list of autocompleter values. If you
want anything else you will need to curry (or bind) them into your
callback.
...
afterUpdateElement:getSelectionId.curry(parameter1, parameter2,
parameter3)
...
function getSelectionId(param1, param2, param3, element, selected){
}

[Proto-Scripty] Re: Class.create and this keyword
In an effort to keep the code clean I'd delegate this functionality to
a dedicated method other than the constructor.

If you really wanted to avoid bind you could just use closures within
the initialize method

document.observe(click,f);

Regardless of the JS framework. A closure is necessary for attaching
class methods to a particular instance and preserve the instance
reference via the this keyword.
This is automatic with the regular Constructor syntax. Defining a
function as an object method inside a constructor creates a closure,
so we can use #bind at the same time as the definition.
The point is, Class.create acts like a prototype more than as a
constructor. I never really thought of that. So I can't bind to my
object instance inside Class.create. And I guess that what acts as a
constructor in Class is the initialize method... So, maybe, I should
define f inside initialize, something like:
var Sub4 = Class.create(Super4, {
baz: bat,
initialize: function () {
this.f = function () {
alert(Class:+this.fu+this.baz);
}.bind(this);
document.observe(click, this.f);
}
});
Is there a cost to operating that way? I guess I won't be able to use
Class.addMethods...
I thought Function.bind was pretty clean myself, but I guess you've
got the sweet tooth for the syntax.
I think #bind is awesome :) It's the bind the function in the
initializer that bothers me, when I compare it to the standard syntax
bind the function at its definition.

[Proto-Scripty] Re: Beginners question, trouble with Event.stop in AJAX
Hi TJ, thanks for the help, I understand the concept of onSuccess and
have updated my javascript. That function runs without an error, but
the observe line does not some to be working (the form keeps trying to
submit using the standard old fashioned method) I think I am missing
something else fundamental.
Here is the javascript:
// Attach handler to window load event
Event.observe(window, 'load', init, false);
function init(){
Event.observe('email-form', 'submit', callProcBasketEmail);
}
function callProcBasketEmail(e) {
var pars = Form.serialize('email-form');
var myAjax = new Ajax.Updater('email-response',
'procBasketEmail.php', {
method: 'post',
parameters: pars,
onSuccess: function(response)
{
Event.observe('password-form', 'submit',
callProcBasketPassword);
}
});
Event.stop(e);
}
function callProcBasketPassword(e) {
var pars = Form.serialize('password-form');
alert(pars);
var myAjax = new Ajax.Updater('password-response',
'procBasketPassword.php', {method: 'post', parameters: pars});
Event.stop(e);
}
and here is the HTML once the first function callProcBasketEmail(e)
has run:
form id=email-form action=# method=post
input id=email class=texterwide type=text name=email/
input id=email-submit class=button type=submit value=Submit/
/form
div id=email-response
form id=password-form action=# method=post
input id=password class=texterwide type=text name=password/
input id=password-submit class=button type=submit
value=Submit/
/form
/div
div id=password-response name=password-response/
Thanks again in advance! :)

Right, because this new line:
Event.observe('password-form', 'submit', callProcBasketPassword);
...will cause an error, because there is no element with the ID
'password-form' yet. Remember that Ajax calls are *asynchronous*
(that's what the A in Ajax stands for). You start the call at the
point in your code where you create the Ajax.Updater object, but then
your code continues immediately without waiting for the Ajax call to
finish. As DJ pointed out, that's what the onSuccess callback is for
-- so you can execute code once the Ajx call has successfully
completed. So it would look something like this:

Thanks for the help, I just tried replacing Event.stop(e); with return
false; in the function but it still submits the form.
I would prefer to do it the new way anyway, if you would be able to
help me...
The first function is called from Event.observe('email-form',
'submit', callProcBasketEmail); which is within a function that is
called when the document loads.
The question is, where to put the event observe to watch the second
form.
My first instinct would be to put it in the function which outputs the
form EG
function callProcBasketEmail(e) {
var pars = Form.serialize('email-form');
var myAjax = new Ajax.Updater('email-response',
'procBasketEmail.php', {method: 'post', parameters: pars});
Event.observe('password-form', 'submit', callProcBasketPassword);
Event.stop(e);
}
(line added just after the ajax function has drawn 'password-form' to
the screen)
But this stops the whole function from working - where should the
observe line be placed to ensure it will work properly?
Thanks in advance, I think once I get over these initial few hurdles
of getting to grips with good practices, I will be fine!
