In html you can apply multiple css classes to a object e.g class="a b c". In jquery its nice and handy to work with all elements with these classes e.g.
jQuery('.b').hide();
In Html 5 using custom attributes, jQuery seems to recognise multiple values e.g. dataset="a b c" as abc i.e. selectable through:
jQuery('tr[dataset="a b c"]').hide();
but
jQuery('tr[dataset="a"]').hide();
does not select any elements with dataset="a b c"
Obviously i can think of two/three work arounds but is there a way for jQuery to recognise multiple values in a custom attr?
