Empty attribute selectors

[kyleaa]

$("[value=]") or $("[value=]") returns unfilled form elements in 1.2.6, in 1.3 it returns nothing.

I'm experiencing the same thing with jQuery 1.3.1

In 1.2.6 I can select all <a> elements without the onclick attribute via:

jQuery('a[onclick=""]')

In 1.3.1 the same expression throws an error. Removing the pair of double quotes returns nothing.

$("[value=]") works in 1.2.6, 1.3 and 1.3.1 as this test case shows:

But $('[value=""]') seems to have stopped working in 1.3.1, returns nothing.

Using the ​test case in Safari 3.2.1, the selector finds the field without the value attribute, but the not the one with the empty value.
