[Proto-Scripty] Problem with prototype.js
hi all,
i m working with prototype.js 1.6 and drag n drop
when i m using this code :new Element.insert(div, {top:content});
i m passing into this method :
Element._getContentFromAnonymousElement = function(tagName, html) {
var div = new Element('div'), t =
Element._insertionTranslations.tags[tagName];
if (t) {
div.innerHTML = t[0] + html + t[1];
t[2].times(function() { div = div.firstChild });
} else div.innerHTML = html;
return $A(div.childNodes);
};
but var div = new Element('div') is not working... my javascript
stop here, but if i replace this line by
var div = document.createElement(div);
all is working fine..
someone can help me to find why first solution is not working?
thanks by advance

[Proto-Scripty] Re: Problem with prototype.js
hi
thanks for your response
more precisions:
i m using rico (2.0rc2) with protoype.js
and this code : http://pastie.org/302127
i don t write this code, just use it and try to understand it ;) (see
http://www.ajaxprojects.com/ajax/tutorialdetails.php?itemid=65)
all working fine with prototype.js (1.4) but when i m upgrading to
prototype.js 1.6
the line 6 (http://pastie.org/302127) is not working as i say in my
previous message because in prototype.js (1.6)
at line 2501 (var div = new Element('div'), t =
Element._insertionTranslations.tags[tagName];)
new Element('div'), not working...but i don t know why
if i replace new Element('div') by document.createElement(div);
all working fine.

Hi,

Two things come to mind:
1. What is assigned to div? It's a variable in that
snippet...what's in it?
2. That syntax looks problematic to me. new Element.insert(div,
{top:content}); tries to use the function Element.insert as a
constructor.
Did you mean (new Element('div')).insert({top: content});? I made
two changes there: I put 'div' in quotes and used Element as the
constructor.
If the above doesn't help, try creating a small self-contained example
that demonstrates the problem and posting it to Pastie[1]. You might
figure it out by doing that, but if not it gives us a complete example
to look at.

[Proto-Scripty] Problem with the sortable system
Hi guys,
I'm having some troubles with the sortable system.
Here's a simple example of my code :
a href=# onclick=reload();Reload/a
ul id=my_ul
li id=li_1test 1/li
li id=li_2test 2/li
/ul
script type=text/javascript
Sortable.create('my_ul', {
onChange:function(){
alert(Sortable.sequence('my_ul').join(''));
}
});
/script
When I load the page, there's no problem, I can reorder the list. But
when I'm clicking on the Reload link, there's no way I can move any
of the new li elements.
The reload(); function is quite basic:
function reload()
{
writediv('li id=li_3test 3/lili id=li_4test 4/li',
'my_ul');
}
So I guess the Sortable function only work if I'm not editing the ul
list. Is there any tips I could use to do it?
Thanks guys.

[Proto-Scripty] Autocompleter Updater
I have an input element with id 'searchtickets' linked to
Autocompleter so that potential search results are returned as the
user types characters in. Updater is then called to update a div
element with id 'dmain' based on that search result. So far I have the
following javascript:
Event.observe(window,'load',function() {
new
Ajax.Autocompleter('searchtickets','searchticketres','data/searchtickets.php',{minChars:3});
Event.observe('searchtickets','change',function() {
new Ajax.Updater('dmain','data/foo.php',{
parameters:$('searchtickets').serialize()
});
});
});
'data/foo.php' simply prints out the value of the POSTed parameters
(for testing purposes). The HTML, for completeness is:
input type='text' id='searchtickets' name='t' size='10' /
div id='searchticketres'/div
div id='dmain'/div
If I start typing in M747 into my input I correctly get some
matches returned. If I select one, say M747100, the input
correctly updates with this but the value passed to Updater seems to
be M747 as this is what 'data/foo.php' returns.
Do I need to use defer() here? I did try adding
$('searchtickets').defer(); just before calling Updater but that
didn't seem to have any effect.

Hi,
What does writediv do? Does it eval scripts? If not...
Try putting together a complete, but very small, example showing the
problem and posting it to Pastie[1]. You'll probably figure out the
problem in the process of doing that. If not, it gives people
something to look at. I'd be very surprised if it's not as simple as
just recreating the Sortable, you just have to be sure the code doing
it gets executed. Ajax.Updater[2] or Element.update[3] might help.

See what happens if you do this:

I think this might be one of those issues where you mean to name a

If you're just starting out with Prototype, it's well worth your time

$() is for select elements by *ID*. If you want to look for them

`this` should reference the same object `window` references (when
anonymous function is called) - global one. Not sure why one would

`select` returns an array and array does *not* have `innerHTML`
(unless you add it explicitly to its `prototype`). Moreover, it parses
string (that you pass to it) as a selector:
alert($(sourceid).down('#RECHNUNGID').innerHTML;

[Proto-Scripty] Storing Control.Slider objects in an array
I'm trying to use a for loop to initialize a large number of
script.aculo.us sliders. I'm finding that, for some reason, I'm
unable to store control.slider objects in an array. For example,
consider this code:
[code]
var contextRaters_primary = new Array();
for(var i = 0; i 1; i++) {
var contextRaters_primary[i] = new Control.Slider($
('contextRaterHandle_primary1'),$('contextRaterTrack_primary1'),
{
axis:'vertical'
});
}
[/code]
I know that this for loop will only iterate once, but I'm using it to
show my point. If I delete the [i] from the end of
contextRaters_primary[i] then it runs fine. But when I try to run
it as I've written it, I get a missing ; before statement error. So
for some reason it doesn't work when I try to store the slider as a
variable in an array.
Could someone PLEASE tell me why this might be? I feel like the
answer is relatively obvious, but I'm relatively new to this and can't
figure it out.
Thanks.

I'm trying to use a for loop to initialize a large number of
script.aculo.us sliders. I'm finding that, for some reason, I'm
unable to store control.slider objects in an array. For example,
consider this code:
[code]
var contextRaters_primary = new Array();
for(var i = 0; i 1; i++) {
var contextRaters_primary[i] = new Control.Slider($
('contextRaterHandle_primary1'),$('contextRaterTrack_primary1'),
{
axis:'vertical'
});}
[/code]
I know that this for loop will only iterate once, but I'm using it to
show my point. If I delete the [i] from the end of
contextRaters_primary[i] then it runs fine. But when I try to run
it as I've written it, I get a missing ; before statement error. So
for some reason it doesn't work when I try to store the slider as a
variable in an array.
Could someone PLEASE tell me why this might be? I feel like the
answer is relatively obvious, but I'm relatively new to this and can't
figure it out.
`[` and `]` can not be part of Identifier. In other words, by
prepending `var` you try to declare a variable and that variable's
name is syntactically wrong : )
Just omit `var`:
...
contextRaters_primary[i] = ...
...
Thanks.

[Proto-Scripty] $$() and Element.observe() question
Hi, I am having trouble with using Element.observe() with $$(). If I
have an element with id=id, I can do this:
$('id').observe('click', function() {alert('clicked');});
However, if I have elements with class=class, I can't do this:
$$('.class').observe('click', function() {alert('clicked');});
I know that $$() returns a document-order array of extended DOM
elements, but I have no idea how to use Element.observe() on the array
returned by $$(). Any help will be greatly appreciated.
