Why is the selectedIndex not an attribute? When I examine the javascript definitions it shows selectedIndex is a property of a select object. How come $(this).attr('selectedIndex') works in 1.5 but not in 1.6.2 RC1? If selectedIndex is not an attribute as claimed then how would one retrieve the selected index of a select control?

Because it is a *property*.

Yes, you are correct, it is a property.

We fixed a bug.
If selectedIndex is not an attribute as claimed then how would one retrieve the selected index of a select control?
Use $(this).prop("selectedIndex") or (even better) this.selectedIndex which is probably more than 100 times faster to execute.

@sradoff Sorry for the confusion. selectedIndex is a property and should never have been retrieved with attr, even though it admittedly did retrieve it. Since 1.6, jQuery has a function for retrieving native properties such as selectedIndex(http://api.jquery.com/prop), but in the past (and this continues to be true) selectedIndex could simply be retrieved with raw javascript:
this.selectedIndex
DaveMethvin ganked me, but I'll post anyway.
selectedIndex is not an attribute.
