Question

here’s a question for the logically endowed. I’m using isotope, a badass jquery mozaic tool that does, among other awesome things, animated filtering of data via code like this …

    $('#container').isotope({ filter: '.metal' });

You can also do an AND for multiple selectors …

    $('#container').isotope({ filter: '.alkali, .alkaline-earth' });

… where anything with class alkali OR class alkaline-earth are selected.

I’m looking for a way to filter the “logical AND” (aka “logical conjunction”), showing ONLY elements where BOTH alkalai AND alkaline-earth classes exist.

I found this stackoverflow answer … How do I combine logical OR with logical AND within a jQuery attribute selector? … but isotope probably needs something more specific in the filter parameter.

Any ideas?

Answer 1

What about:

$('#container').isotope({ filter: '.alkali.alkaline-earth' });

That’s the common way to select elements that have both class names defined.
