Any relation to http://bugs.jquery.com/ticket/7212 ?

Duplicate of #7243.

Isn't #7243 a duplicate of this bug, since it was created after it?

Please re-open ... http://jsfiddle.net/darkangel/geX3c/1/

Isn't that an invalid selector? You can't do !=] or =] - you have to have quotes. Changing that makes it work:

http://jsfiddle.net/geX3c/2/

As mentioned on IRC, it worked in 1.4.2 and the documentation says the quotes are optional.

The documentation should be updated if the selector is invalid.

Thanks.

I've updated all the selector docs to represent this:

http://api.jquery.com/category/selectors/attribute-selectors/

"Attribute values in selector expressions can be written as bare words and must be surrounded by quotation marks."

Shouldn't that be *cannot* be written as bare words? Or simply ...

"Attribute values in selector expressions must be surrounded by quotation marks."

The docs are now somewhat confusing, as they suggest doing something syntactically impossible: jQuery('[attribute|='value']').

[[Image(http://gyazo.com/d29d38d82859a4c574cb96fe19cd9ff6.png)]]

All the attribute selector "name" values should combine single/double quotes and be formatted as either jQuery("[attribute|='value']") or jQuery('[attribute|="value"]'), whichever is more universally consistent.

I've changed the syntax errors in all attribute pages to match

jQuery('[attribute|="value"]')

Wasn't logged in, but that was me :)

Changing the docs isn't a sufficient fix for this problem, especially for a 1.x.x release, since it potentially breaks a lot of existing code. Additionally, examples in the CSS spec suggest that quotes are optional: http://www.w3.org/TR/CSS2/selector.html#attribute-selectors

This bug was closed as duplicate of #7243, but they're really two separate issues.

Quotes are optional only if the value part is an ident. This is detailed in the css3 grammar.

Ok, Karl provided another test case:

http://jsfiddle.net/XEAuc/1/

This is more than when there's no content on the right hand side. I'll look into this.

Think this might fix it, will try later:

.replace(/=\\s*([^'"\\]]*)\\s*\\]/g, "='$1'")

Ensure that unquoted attribute selectors are quoted (allowing them to go into qSA/matchesSelector properly). Fixes #7216.

This "bug fix" doesn't seem to work correctly in all cases. Refer to the example on the Selectors page of the Documentation for a simple example that doesn't work with jQuery 1.4.4.

http://api.jquery.com/category/selectors/

(example in second paragraph... try to run this code in jQuery 1.4.4)

It seems that the modification made by this bug fix in the Sizzle function seems to choke on some of the meta-characters that are supposed to be allowed in selectors. In particular, some of my selectors contain the "=" character in an attribute, but the quoting logic doesn't seem to handle this case properly.

Please submit a reduced test case which reproduces the issue you are experiencing (ideally on http://jsfiddle.net). So that we can investigate this issue further.

Reduced test case.

http://jsfiddle.net/2KPBQ/

Under 1.4.3 and 1.4.4, it doesn't work, but does under 1.4.2. (Maybe the issue was introduced in 1.4.3, but I didn't notice).

Insignificant correction to test case.

http://jsfiddle.net/2KPBQ/1/

test case which works under jQuery 1.4.2/1.4.3 but fails under 1.4.4

The testcase provided in comment 23/24 also work in 1.4.2/1.4.3 but fail under 1.4.4 (Opera 10.63 and FF 3.6.12 tested)

Additionally,

$("input[name=song[attachment]]").length

returns 0

$("input[name='song[attachment]']").length

returns 1

The first case used to work in 1.4.2 and is not working on 1.4.4. Is this being looked at as well?

The additional issues that were brought up here were taken care of in #6093.
