[Proto-Scripty] Re: Move an image
Hi,
your code does not work, because there is no Element method called
move.
You have to a) create a new Effect for this and b) you must merge the
two options hashes before using them since move expects only one:
new Effect.Move('banner1' , $H(options).merge({x: 60, y:-30}))
I would also suggest to use this way of effect creation for any effect
instead of calling object methods on Element objects, since it
emphasis the separation of script.aculo.us effects and prototypes
(DOM-) extensions.

Why doesn't move or Parallel work in this queue?

I was in the IRC room, and a nice enough gentleman said that the docs
contained everything, but obviously they don't.
How can I make the images move to the right or left in the code I have
provided below.
function sequence() {
var options = { queue: 'end', duration:2 };
var fade = { queue: 'end', duration:5 };
$('banner1').appear(options);
$('banner1').move(options, { x: 60, y: -30 });
$('banner1').fade(fade);
$('banner2').appear(options);
$('banner2').dropOut(options);
$('banner3').appear(options);
$('banner3').fade(fade);
$('banner4').appear(options);
$('banner4').dropOut(options);
$('banner5').appear(options);
$('banner5').fade(Object.extend(options, {afterFinish:
sequence}));
}
Thanks in advanced for any help!

[Proto-Scripty] Re: Move an image
At first: Sorry but i missed that you do not specify all required
options for Effect.Move
You should check at http://wiki.github.com/madrobby/scriptaculous/effect-move
, there you will find that you have to specifiy x, y and mode at least.
And i just realized that using a hash as container for options does
not work, at least it does not here. My apologies.
Other than that the code should work just fine if you replace the $
('banner1').move(... line with
new Effect.Move('banner1' , {x: 60, y:-30, mode : 'relative'});
or mode : 'absolute' , i can't tell from this snippet you posted want
you want to do.
If this does not work: Do you have script.aculo.us and prototype
imported correctly to your page? And what versions of both are you
using?

I know nothing about DOM other than the acronym!
How do I do this? When I have changed the effects from the
$(element)[effect] syntax to the one you are suggesting, none of the
effects work. Within the framework of the snippet I inserted in my
first email would you please show me how the way you are talking about
works?
Thanks,
Leonard.

[Proto-Scripty] Re: Move - OnMouseMove- Only once
The problem is that you have different scopes in all callbacks.
So the callback called when a mouseover event bubbles up, does not
know about ausgefahren as defined in the callback of dom:loaded and
so on.
You could use a global variable to save the state or use a custom
object with the callbacks as methods and then fix the scope via bind()
or bindAsEventListener() to your object.
It may be a bit overdone but i would go for something like:
script src=prototype.js type=text/javascript/script
script src=effects.js type=text/javascript/script
script type=text/javascript
var MyMenu = Class.create({
initialize : function(menu_element) {
this.menu_element = $(menu_element); //make sure you have an
extended element
this.state = 0; // the state of the menu
this.mouseover_callback =
this.mouseOver.bindAsEventListener(this); //callbacks
this.mouseout_callback = this.mouseOut.bindAsEventListener(this);
this.menu_element.observe('mouseover', this.mouseover_callback);
this.menu_element.observe('mouseout', this.mouseout_callback);
this.queue = Effect.Queues.get(this.menu_element.identify() + '-
scope'); //create a queue with a unique name
},
mouseOver : function() {
this.queue.each(function(ev) { ev.cancel(); });
new Effect.Move(this.menu_element, {
x:0,
y:50,
duration: 0.2,
mode: absolute,
queue : {scope : this.menu_element.identify() + '-scope',
limit : 1},
afterFinish : function() { // using an effect callback to
make sure state is changes _after_ the last frame was renderd
this.state = 1;
}.bind(this)
});
},
mouseOut : function() {
this.queue.each(function(ev) { ev.cancel(); });
new Effect.Move(this.menu_element, {
x:-200,
y:50,
duration: 0.2,
mode: absolute,
queue : {scope : this.menu_element.identify() + '-scope',
limit : 1},
afterFinish : function() {
this.state = 0;
}.bind(this)
});
}
});
var menu;
document.observe(dom:loaded, function(ev) {
menu = new MyMenu('aeusseresmenue');
});
/script
I hooked in Jim's suggestions to stop running effects in the queue
with their cancel() method, this prevents the issues with fast mouse
movement.
Obviously this code works without saving the current state, i just
left that in because i don't know if you want to use the menu's state
somewhere else.

Thanks, you are right, it works.
However, I tried the solution which saves the stat but i wasn't able
to solve the problem, I made it even worse...

The problem is that you are triggering a mousemove event _every_ time
you move the mouse within the div, and every single time you create
a Move effect.
So when you leave the div there is a mouseout event and also the
mousemove event from your last mouse movement.
The flickering you see is the interference of the two created move
effects. Since script.aculo.us renders all ongoing effects in
parallel, unless you specify otherwise.
As a workaround you could use an extra Event.Queue for your menu, and
limit the effects in the queue to only one at a time.
This is a bit dirty, but it works sort of. Of course you can mess
things up if you move your mouse very fast (depending on the effects
duration) in and out of the div.
It maybe better to save the state of the menue somewhere and check
that before creating a new effect.
