.attr("value") 1.2.6 versus 1.3.1

[bdenosky]

xhtml snippet: <p id="bpUsername"><input name="bpUsername" type="text"/></p>

jquery snippet: alert($("#bpUsername input").attr("value"));

The value is returned correctly in 1.2.6

Upgrading to 1.3.1 resulted in a returned value of "undefined"

It seems to return an empty string in both versions for me. Is there a particular browser that returns the incorrect value?

Are you serving up this document as application/xml+xhtml ? I wonder if that might cause it to return undefined, or whether it's significant that the markup has no value attribute.

It is being served up as application/xml+xhtml.

If the alert is set to fire after information has been entered into the input field, that's when the error is produced in 1.3.1. In 1.2.6, the value inputted into the field is displayed.

Firefox, Chrome, Safari and IE7 all behaved the same with regards to this bug.

Can you attach a test case? I just can't make this bug happen.

I can't repro this and the OP didn't provide a test case.
