Question

I tried this but it’s not working:

var a = $('a');
var b = $('p');
var c = $('div');

$(a, b, c).hide();

Answer 1

jQuery selectors work like CSS selectors. You can select multiple independent sets of elements if you separate their selectors with commas:

$('a, p, div').hide();

If you already have fetched the different sets, you have the option of re-fetching them together (above), running .hide() on each one, or merging the sets to run .hide() once:

a.add(b).add(c).hide();

For more information see the .add() documentation.
