[Proto-Scripty] query seems to keep returning
Hi,
I've never had this problem with prototype before. I'm querying a
twisted python web service that I wrote with a simple GET request,
returning json, but for some reason the responseText always seems to
be .
function make_request() {
debug(in make_request with url + url);
new Ajax.Request(url, {
method: get,
onSuccess: function(transport) {
debug(query successful);
debug(response was ' +
transport.responseText + ');
},
onFailure: function(transport) {
debug(query failed);
}
});
}
In the browser I end up seeing
* in make_request with url
http://localhost:8000/route/?start=sta-917end=sta-10715starttime=1274469161
* query successful
* response was ''
And yet if I capture the traffic, the response looks fine.

So why am I not seeing it in transport.responseText ?

[Proto-Scripty] new class instance and string is not a function error
Hi group
I tried to store a list of Class and fetch those class definition to
create new instance in the following way:
myclasses = {
A: Class.create({...}),
B: Class.create({...}
...
};
...
for (var i = 0; i myclasses.length; ++i) {
var cls = myclasses[i];
var obj = new cls(...);
}
Unfortunately the above code failed at var obj = new cls(...); and it
throws out the exception: string is not a function. Do you have any idea?
Thx,
Green

[Proto-Scripty] Blur, Focus, Event Delegation
Not sure if this is a bug report, feature request, help request, or
even just a complaint about the state of the world :)
Using Prototype 1.7 rc2, I have been exploring event delegation with
the new Element#on functionality, using the css selector filter. My
initial tests with click (and dblclick) events worked fine, but when I
moved on to blur and focus, things broke.
The blur and focus events work fine as long as the the '.on' is for
the actual (in my sample) input fields, but the events do not trigger
(bubble) if I set the handler on an ancestor element.
It is *possible* to get the functionality (bubbling) to work, by
bypassing some of the prototype functionality, using .addEventListener
(for most browsers), and .observe with 'focusin' and 'focusout' events
(for IE). (I found a sample for that at http://www.ruby-forum.com/topic/159048,
tried a variation of the code at http://pastie.org/pastes/186221).
That though falls back on the old techniques, where the handler needs
do something like findElement to figure out what the 'requested' event
should be associated with.
So:
Is there a way to get $(ele).on( some_event, css_selector ) ...
to trigger for blur and focus events on descendant elements of ele
with rc2?
Is that 'intended' to work with the latest code, since it is supposed
to provide first-class support for event delegation?
The 'basic' code I am trying to use is:
DelegationExplorer.start( ele, 'click', '.special' );
DelegationExplorer.start( ele, 'dblclick', '.special' );
DelegationExplorer.start( ele, 'blur', '.special' );
DelegationExplorer.start( ele, 'focus', '.special' );
...
start: function(){
...
this.handlers[localEvn][eleId] = $(eleId).on( localEvn, localSel,
function( triggerEvent, matchElement ) {
DelegationExplorer.genericHandler( triggerEvent, matchElement );
});
were ele is an ancestor of an input field [type=text or textarea]. I
have debug / introspection / reporting code in genericHandler to tell
which events are getting through. Click and dblclick get reported,
blur and focus do not.
Using:
this.handlers[localEvn][eleId] = $(eleId).on( localEvn,
function( triggerEvent, matchElement ) {
DelegationExplorer.directHandler( triggerEvent, matchElement );
});
triggers just fine, when eleId is the actual input field.
The 'fudge' to get [most of] the functionality (without the css
filter) is:
var myRoot = $('frm');
if( myRoot.addEventListener )
{
myRoot.addEventListener( 'focus', DelegationExplorer.directHandler,
true );
myRoot.addEventListener( 'blur', DelegationExplorer.directHandler,
true );
} else {
// IE supports focusin and focusout
myRoot.observe( 'focusin', DelegationExplorer.directHandler );
myRoot.observe( 'focusout', DelegationExplorer.directHandler );
}
where frm is again an ancestor of the input fields

[Proto-Scripty] Re: new class instance and string is not a function error
I found the problem. It's not caused by class array actually.
The following code demonstrate what I was trying to do:
var A = Class.create(...);
var B = Class.create(...);
Object.extend(B, {
A_ext: Class.create(A, {...}),
A_list: {
A1: Class.create(B.A_ext, {...}),
A2: Class.create(B.A_ext, {...})
}
});
The problem of above code is that when it try to reference B.A_ext, which
has not been initialized yet. And splitting the Object.extend(B to 2
extend actions solves the problem:
Object.extend(B, {A_ext: Class.create(A, {...}});
// now that B.A_ext has been initialized, we can use it safely
Object.extend(B, {
A_list: {
A1: Class.create(B.A_ext, {...}),
A2: Class.create(B.A_ext, {...})
}
});

To allow this, you'd want your server to respond with these headers:
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET
Access-Control-Allow-Headers: x-prototype-version,x-requested-with
So just to see if this worked, I added support for an OPTIONS request, and
responded with the above. It did work in that the browser did follow up with a
GET request, and my server sent the response as content-type application/json.
Unfortunately it hasn't helped my situation as the transport.responseText is
still empty.
This is my new trace:

Any idea why the responseText would still come back empty?
