':text' is case-sensitive on type whereas '[type=text]' is case-insensitive

[david@…]

Documentation for :text selector says $(':text') is equivalent to $('[type=text]') however I have verified that it is not.

Assume want to match <input type="TEXT"> -- N.B.: uppercase TEXT.

'input:text' is case sensitive on type and thus does not match.

'input[type=text]' is case insensitive and thus does match.

The bug is that the :text filter calls elem.getAttribute( "type" ) which returns "TEXT" in this case, whereas elem.type returns "text" in this case.

In the definition of the :text filter function, replace:

var attr = elem.getAttribute( "type" ), type = elem.type;

with:

var attr = elem.getAttribute( "type" ).toLowerCase(), type = elem.type;

There is currently a note in the docs for :text that clearly states:

Note: As of jQuery 1.5.2, :text selects input elements that have no specified type attribute (in which case type="text" is implied). (note here the case of 'text')

Baring this in mind, I think we'll have to leave this ticket open for a discussion regarding whether or not a change here is warranted or simply a change in the wording of the docs to reflect the exact behaviour.

I went ahead and added a PR on Sizzle if we want this.  pull request
