[Proto-Scripty] Re: Avoiding bubbleling
Yeah
I had that problem also (http://www.partygek.nl .. see the carousel).
What I did was something like this
div id='container1'
div id='logo'/div
/div
I put a mouseover and mouseout on container1. on mouseover and
mouseout I check the fire element is a decended of container1 OR is
container 1 ... if not, it's outside container1 ;-)

Hi,
On the mouseover bit, the problem isn't really the bubbling, since
you'd also get that same behavior if the mouse were hovering over any
part of the logo div -- over some padding, for instance -- since
mouseover fires over and over again at the slightest change in mouse
position. Really what you want to do is track whether the logo is
already dimmed and only trigger the effect if not. Just set the flag
when you first dim the logo, then don't dim it again. (You can't use
Element#visible because if you ask when the effect is still running,
that will come back true.) The flag could even be whether the
mouseover handler is attached -- detach it when you dim the logo,
reattach it when you un-dim it.
I haven't used mouseout enough to be able to help, really, but some
thoughts/observations:
* Will mouseout reliably fire on logo when logo is invisible, on all
of your target browsers?
* To know whether you're getting a mouseout from 'logo' itself as
opposed to the image within it, you can use Event#findElement:
var src;
src = event.findElement();
if (src src.id == 'logo') {
// It's the logo itself, undim it
}
* You'll want to Test This Like Crazy on a wide variety of browsers.
* If you search around, you may find implementations that emulate the
mouseenter and mouseleave events on browsers that don't natively
support them. I'm pretty sure that mouseenter and mouseleave are what
you want for the above, but browser support for them varies.

of hiding the logo.

Hi, I actually figured it out, there were a couple of errors in my
syntax.
However, I do have one question regarding adding multiple Droppables.
Is there any easy way to just declare all the droppables in one line
of code?
For example, I have five DIVs that are my droppables. They all have
an ID, eg., 1, 2, 3, 4, 5.
Right now, I have:
Droppables.add(
'1', {hoverclass: 'hoverActive', onDrop: moveItem}); $
('1').cleared = true;}
How would I declare all of the droppables (1, 2, 3, 4, and 5)?
['1', '2', '3', '4', '5'].each(function (id) {Droppables.add(id,
{ ... })});
But note that '1' etc. are not valid IDs in HTML:
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be
followed by any number of letters, digits ([0-9]), hyphens (-),
underscores (_), colons (:), and periods (.). [http://

[Proto-Scripty] Problems with XML in IE 7

In Firefox I am getting a good result on the alert, in IE it returns

When I am loading the responseText from transport into Xmldoc it
retruns a good result:

[Proto-Scripty] Dragged and Confused
This is some working code that makes a Draggable:
this.draggable = new Draggable(ts.up(div.rsrcRow), {
revert: true,
ghosting: true,
onStart: function(draggable, event) {
var G = window.grid;
var dzs = G.gridElt.select(div.rsrcRow);
G.dropZoneElts = dzs;
// But why doesn't this store window.grid ?
G.shouldBeGridObj = this; // ? But IS draggable.options.
}.bind(window.grid),
...
});
I would think the value of 'onStart' here would be the
wrapper that bind puts around the function object, but
it clearly is not.
window.grid is a prototypejs-style object, and when
onStart is called, 'this' is bound not to that object,
but to draggable.options. And looking at it after
the drag+drop (as window.grid.shouldBeGridObj) I can
see that the 'onStart' member is the original function body
with no indication of a bind-wrapper.
What am I missing here?
TIA,
Mike

[Proto-Scripty] Theoretical Question
I am a web developer that is well versed in PHP and MySQL development environments. Lately, I have been picking up Prototype and script.aculo.us on a piece by piece basis. I have found myself using (or relying) heavily on event observers and calls to Ajax.Update() functions which pass serialized form variables. This can partially be explained by the fact that my sites are normally entirely DB driven and partially by the fact that I have not been doing anything too fancy. In general practice, I use various script.aculou.us visual effects and only a smattering of the Prototype helpers, the majority of the work on my pages is then passed to a php script and the content is in turn updated via an Ajax.Update. My question is, how sloppy is this? Or is it a viable implementation?

[Proto-Scripty] Re: New use case for Sortable tree?
Eric, I'm interested in seeing your solution. I have the same problem of trying to prevent the nested sortables from accepting groups. Stephen On Jan 7, 3:35 pm, Eric eylin2...@gmail.com wrote: I ended up extending Scriptaculous to allow for this behavior. The changes in the new API are: 1. Added a groupAccept option toSortable. It takes the same argument as Droppables' accept, but is used to limit whatgroupsin aSortabletreewill accept. (Group is defined as any element in theSortablelist that contains a nested list). For the example in my previous post, I gave all Items a class name like item, and set groupAccept to item. This ensures only Items can be dropped intoGroups,Groupscannot be dropped intoGroups. 2. To support the implementation of #1, I added an option to Droppables called acceptIf. acceptIf takes a function that takes two arguments: the dragged element and the Droppable object. acceptIf should return true if the drop should occur and false otherwise. This is meant to be a more general and dynamic way of specifying what can be dropped than the existing accept and containment options. If some of you are interested in these enhancements, I can post the code here. How do I go about adding these enhancements to the Scriptaculous trunk?

Additionally, Items can be dragged intoGroups(each Group contain an UL). However, I want to preventGroupsfrom being dragged intoGroups, but there doesn't seem to be an option inSortableto achieve that. The solution would be something like being able to specify accept class names for theSortabletree'snested ULs, so only Items would be allowed insideGroups. But that doesn't seem to be possible. Is there something that I am missing, or would doing this require me to extendSortable'simplementation myself? Thanks, Eric By the way, in the course of implementing my drag-and-droptree, I found thetree-dump output ofSortabletreeto be clumsy to use on the server side, because it would require me to recreate thetreein the database each time. Instead, I added a Draggables observer for the onEnd event to capture each sorting action, and send to the server only the change that was made: what element was dragged, which container it was dragged to and at what position. This required a bit of additional coding to determine the location and position of dragged element, but made the server side code simpler and faster.

[Proto-Scripty] Ajax.Request delay
Hello,
I'm having a weird issue when trying to use Ajax.Request in a function
within a function.
I'm using LiveValidation from http://www.livevalidation.com/ which
uses prototype.js. It has a custom attribute that allows you to pass
in a custom function to validate against. I call this custom function
so that I can check a username against a database using the
Ajax.Request method.
The way it should work is, if the username is not found, it returns
true, otherwise false. I haven't been able to get that exact result
so I've created some workarounds. True or False is passed to the
custom function of LiveValidation and validates based on true or
false.
However, for some reason, there is a delay in passing the value from
the LiveValidation custom function. So let's say the username bee is
taken. As I type the word 'bee' and the LiveValidation is being
passed to the Ajax.Method, it is returning false. If I continue to
type, let's say to the word 'beer,' it finally comes back true, even
though 'beer' is not taken. Once I leave that field for the next one,
it validates again and comes back false for the word 'beer.' Thus the
delay.
Here is the code I am using for the Ajax.Request function:
*
function validateEntry(c,f) {
var url = ajaxProcessor.php?f= + f + c= + c;
new Ajax.Request(url, {
method: 'post',
onComplete: function(transport) {
if (transport.responseText == YES){
return entryResponse = 1;
}else{
return entryResponse = 0;
}
}
});
if (entryResponse == 0) {
return false;
}else{
return true;
}
}
I'm using entryResponse because I haven't figured out how to return
true or false.
Here is the custom function for LiveValidation:
script type=text/javascript
var f1 = new LiveValidation('f1', { validMessage: Ok! } );
f1.add( Validate.Custom, { against: function(value){ return
validateEntry(value,3) }, failureMessage: Username already
taken! } );
/script
***
Now I tested to see if it was the LiveValidation that was causing the
delay in sending the correct value to the Ajax.Request function and
it's not. Somewhere within the Ajax.Request method, the return values
are being delayed.
Can anyone help?

[Proto-Scripty] Re: Theoretical Question
The pattern you've described doesn't sound too awful in practice, but if you start updating large chunks of your page at once, consider making the server share some of the work with the client. If you've already got the whole page there, and all the script, it doesn't make sense to (for example) update an entire table or grid when you've just deleted a row or re-sorted the contents. If you can get away with posting only the new sort order or the delete request to the server, and updating the page in the browser when you get a 200 header back from the update script, then you can improve your performance quite a lot, both for the client and the server.
