javascript - How to have "and" and "or" conditions in jQuery selector -

-

i check if 2 separate divs returning true hasclass.

    if($('#first-name, #last-name').hasclass('has-focused')) {         $('#personal-info').valid();     }

this checks if either 1 has class 'has-focused'.

instead this:

    if($('#first-name').hasclass('has-focused')&&$('#last-name').hasclass('has-focused')) {         $('#personal-info').valid();     }

however, solution feels bit clumsy. possible this.

    if($('#first-name'&&'#last-name').hasclass('has-focused')) {         $('#personal-info').valid();     }

you can't that, though can have filter based solution like

if ($('#first-name, #last-name').not('.has-focused').length == 0) {   $('#personal-info').valid(); }
