.attr(map): Quotes seem not to be optional

[anonymous]

Don't know whether this is a bug in jquery, a bug in the api-documentation ​http://api.jquery.com/attr/ or just a missing feature, but I thought it is worth reporting:

This does not work without quotes: $mydialog.attr({

role : 'dialog', aria-hidden : 'false', aria-labelledby : 'top'

});

Error in line aria-hidden: Missing : after property id

It works with quotes only:

$mydialog.attr({

'role' : 'dialog', 'aria-hidden' : 'false', 'aria-labelledby' : 'top'

});
