[Proto-Scripty] Help destroying many events on tr mouseenter and mouseleave

[kstubs]

I have something like this:

tr.on('mouseenter',thiz.Mousing.bindAsEventListener(thiz));
tr.on('mouseleave',thiz.Mousing.bindAsEventListener(thiz));

This table is built frequently (every few keystrokes by the user) so I need 
to setup the mouseenter and mouseleave event and tear them down just as 
quickly.

So, when I go to update the table container (whipe it out each time) I'd 
like to call one or two very convenient inokes on the tr's, something like:

this.table.select('tr').invoke( ... tear down those events here ... );

Is this the correct approach, or must I itterate through the result of each 
tr and tear them down this way?

[Proto-Scripty] Event Keyup a-z key response

[kstubs]

Is there a clever way to ignore all other keystrokes, like arrow keys and 
only responsd to keycodes ranging from a-z and 0-9?  I guess another valid 
keystroke would be SHIFT+.  So something like:

onKeyUp: function(e) {

  // if not valid keystroke event
  return;

  // otherwise, do the following code
}

[Proto-Scripty] Re: History and onpopstate

[pedz]

This isn't using prototype but works:

window.onpopstate = function (even) { ... };

new Event.Handler(element, ...) requires element be an element.  window 
doesn't work.  Not a big deal.  I'm using Firefox 5.  I don't know (yet) how 
portable the above is going to be.

Wow, you just have to love Javascript, so flexible sometimes!  What an 
amazing language, I tell ya.
Thanks for that shortcut ilandril!

[Proto-Scripty] History and onpopstate

[pedz]

My first attempt to use HTML 5's onPopState isn't working.  I did:

$$('body')[0].on('popstate', Raptor.makeWrapper(function(event) {
console.log('popped');
}));

I've tried a few different capitalizations but, so far, it isn't logging the 
'popped' message.

Any suggestions on how to hook this up?  It appears (from the HTML 5 
documentation) that the event handler needs to be hooked to the body 
element.

[Proto-Scripty] Re: Object from string

[kstubs]

OK, I figured it out.  Here is my solution, and ultimately I need an Object, 
as you can see I'm extending args in the end, so is there a way to avoid 
creating the hash, then casting the hash to an object?

var idx = itt + 1;
var name = 'p_Value' + idx.toString();
var h = $H();
h.set(name, names[itt]);
Object.extend(args, h.toObject());

[Proto-Scripty] Object from string

[kstubs]

I hope I haven't asked this before!!  OK, so if have a name string like 
this:

var name = 'somename' + x// assuming x = 1

and some value = '1234'

I need the object:

{ somename1: '1234' }


But I can't figure out how to get here.  Please help.
Karl..
