[jQuery] Re: jQuery won't recognise attribute names containing [square brackets]
I knew about :input, but my brain just pre-supposed it meant only input elements so I had kind of disregarded them somewhat. So thanks for pointing that out!

[jQuery] Re: jQuery won't recognise attribute names containing [square brackets]
Hey Marty, I couldn't live without PHP's square brackets. I just about always want to split up a form into component parts. I could easily write something using RegExp to do this for me, but having it all built in is just lovely. Great that Rails has it too. Cheers, Dave

Hi Aaron, Good styles there with the name attribute stuff. Not so good if you want to grab other entities such as selects, but good to see that it accepts non-standard characters.
[jQuery] Re: jQuery won't recognise attribute names containing [square brackets]
All Browsers assign form data variable names according to the name
attribute, not id.
PHP uses square brackets as a shortcut to automagically build arrays
from the request data. Like Karl said, this is illegal in HTML, and
still seems not allowed in XHTML according to
http://www.w3.org/TR/2008/PER-xml-20080205/#sec-common-syn (XHTML is
XML, remember).
That section has a paragraph beginning The ASCII symbols and
punctuation marks, along with a fairly large group of Unicode symbol
characters, are excluded from names..., which leads me to believe
square brackets are still disallowed in XHTML names. The allowed
unicode ranges given exclude the ascii range #x5B to #x7F (square
brackets are #x5B and #x5D).
Assuming I'm reading the spec correctly. Most of the expanded
characters in XML seem to be in a much higher range than ascii.
Personally, I wish PHP didn't do this with square brackets.

Thoughts?
[jQuery] Re: jQuery won't recognise attribute names containing [square brackets]
Actually, according to the HTML 4.01 spec, the name attribute on input
elements[1] is defined as being of type CDATA[2], which is very permissive
in the kinds of characters it allows. There is a section in the XHTML
1.0spec that talks about restricting the allowed characters in the
name
attribute[3], but since it's talking about fragment identifiers, I'm not
sure whether it applies to form field names or not (that would suck if it
did, though).
As for the OP's problem, this has worked beautifully for me:
$(input[name='foo[bar][baz]']) // notice the single quotes around
foo[bar][baz]

[jQuery] Re: jQuery won't recognise attribute names containing [square brackets]
Pre jquery I have used an id without the square brackets and a name with the square brackets. I used the id in my javascript and the form would submit with the name.

I'm sure most people know PHP uses square brackets within form element names to submit multi-dimensional arrays, ie: contact[name] contact[email] contact[telephone] contact[options][option 1] contact[options][option 2] contact[options][option 3] This is read natively by PHP as: contact = array ( name, email, telephone, options = array( option 1, option 2, option 3 ) ) In a way, jQuery's refusal to recognise square brackets makes sense, as it leans towards attribute selectors (which are fantastic tools), but vanilla getDocuementById() works, so I'm wondering why jQuery hasn't some kind of check for this kind of thing?

You can use square brackets, you just have to put a '\' before them (which has to be done as '\\' because of JavaScript's encoding) http://docs.jquery.com/Frequently_Asked_Questions#How_do_I_select_an_element_that_has_weird_characters_in_its_ID.3F Karl On Feb 8, 2008 1:28 AM, Dave Stewart [EMAIL PROTECTED] wrote: I'm finding it impossible using jQuery to select any attributes with square brackets in them.

[jQuery] Re: jQuery won't recognise attribute names containing [square brackets]
Wow, that's really useful to know, thanks Karl. I think I'll just use a regular expression: selector = selector.replace(/(\[|\])/g, '\$1') It would be really useful if this were an option, somehow. My jQuery- foo is not all that. Any ideas, anyone? Cheers, Dave
[jQuery] Re: jQuery won't recognise attribute names containing [square brackets]
Remember also that technically in HTML id and name attributes can't contain '[]'s. 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://www.w3.org/TR/html401/types.html#type-name In XHTML name can contain a lot more though. ( http://www.w3.org/TR/2002/REC-xhtml1-20020801/#C_8 ) Browsers have relaxed the HTML rules and allowed name to contain whatever it can contain in XHTML. PHP uses the name attribute rather that id and so it gets away with it because the relaxed rules.
