Discrepancy between jQ 1.5 vs 1.6 in selected attribute in DOM

[n3croman@…]

Check this sample:  http://jsfiddle.net/jPKQz/3/ When running with jQuery 1.5 and analyzing the created DOM using Firebug/DevTools/Dragonfly/IE9, none of option tags in created select boxes contain selected="selected" attribute. When running this sample with jQuery 1.6 the first two select boxes contains selected="selected" attribute on given options - is this the expected behavior?

See:  http://blog.jquery.com/2011/05/12/jquery-1-6-1-released/

Also, is there anyway to reduce your test case to the smallest possible example of offending code?

 http://jsfiddle.net/e57CU/ - open it in Chrome, open Dev tools and check the attributes of option tags - no selected="selected" here, although in each of select boxes an item is selected. Now change the jQuery to 1.6 and check it again, now the first select box has selected="selected" option - but why? Is this the expected behavior?

Yes, this is expected default browser behavior. Previous versions of jQuery set the property (which is why it is still selected without seeing the attribute there). 1.6 sets the actual attribute which is why you see an attribute there, but the attribute is really only for setting the default/initial value. The property is what keeps track of current state.
