Array.without() and using an array of withouts.

Hi.

I''ve got the following piece of code which is doing what it is
supposed to be doing ...

$(s_Form)
	.getElements()
	.without($(s_Key))
	.invoke(''observe'', ''blur'', keyEdited)
	.invoke(''observe'', ''change'', keyEdited);

I also have another bit of code which enables/disables the
Reset/Submit buttons on the form ...

$(s_Form)
	.getElementsBySelector(''input[type=reset]'',
''input[type=submit]'').
	invoke(b_Dirty ? ''enable'' : ''disable'');

What I now want to do is amend the first bit of code to also NOT
attach the events to the reset and submit buttons.

I don''t know the IDs of the buttons. This code is in a library and is
being added to an existing setup.

I''ve had to make a small "allowance" to get the
"key" element for the form.

I tried ...

$(s_Form)
	.getElements()
	.without
		(
		$(s_Key),
		$(s_Form)
			.getElementsBySelector
				(
				''input[type=reset]'',
				''input[type=submit]''
				)
		)
	.invoke(''observe'', ''blur'', keyEdited)
	.invoke(''observe'', ''change'', keyEdited);

But that didn''t work.

I also tried ...


$(s_Form)
	.getElements()
	.without
		(
		$(s_Key),
		$(s_Form)
			.getElementsBySelector
				(
				''input[type=reset]''
				),
		$(s_Form)
			.getElementsBySelector
				(
				''input[type=submit]''
				)
		)
	.invoke(''observe'', ''blur'', keyEdited)
	.invoke(''observe'', ''change'', keyEdited);


But that didn''t work.

I think the reason is that .getElementsBySelector returns an array and
the without method wants individual elements.

Any suggestions?

Regards,

Richard Quadling.

Aha.

	$(s_Form)
		.getElements()
		.without
			(
			$(s_Key),
			$(s_Form)
				.getElementsBySelector
					(
					''input[type=reset]''
					)
				.first(),
			$(s_Form)
				.getElementsBySelector
					(
					''input[type=submit]''
					)
				.first()
			)
		.invoke(''observe'', ''blur'', keyEdited)
		.invoke(''observe'', ''change'', keyEdited);

is working, but could it be made any neater?

you
want to observe, then simply call $$(''.keyEdited'').invoke(...)
or you
could do a more complicated CSS selector using ":not()".  Maybe 
something like the following:

$(s_Form)
 
.getElementsBySelector(''*:not(input[type=reset]):not(input[type=submit]):not(#''
+ $(s_Key).id + '')'')
  .invoke(...)

As a test, I used ...

	$(s_Form)
	
.getElementsBySelector(''*:not(input[type=reset]):not(input[type=submit]):not(#''
+ $(s_Key).id + '')'')
		.invoke(''observe'', ''blur'', keyEdited)
		.invoke(''observe'', ''change'', keyEdited)
		.each(function(o) { console.info(o.id); });


And my console is filled with LOADS of empty elements (those with no
ids) which suggests that it is looking at everything rather than just
the form elements. This is also what the dox say about
getElementsBySelector().

I think I''ll create a patch for without to allow it to deal with an
array of arguments as well as multiple arguments.

I''ve got the adding an ID to the Reset and Submit buttons which is in
the form of s_Form + ''Reset'' and s_Form +
''Submit'', so I can use ...

	// Attach standard events.
	$(s_Key)
		.observe(''change'', keySelected)
		.observe(''keypress'', keySelected);
	$(s_Form)
		.observe(''submit'', formSubmit)
		.observe(''reset'', formReset)
		.getElements()
		.without
			(
			$(s_Key),
			$(s_Form + ''Reset''),
			$(s_Form + ''Submit'')
			)
		.invoke(''observe'', ''blur'', keyEdited)
		.invoke(''observe'', ''change'', keyEdited)
		.each
			(
			function(o)
				{
				if (b_Debug)
					{
					console.trace();
					}
				}
			);

I love the chaining I can do.
