<div id="test" class="a1 a2 a5"></div> 

Answer 1

You could use the jQuery is function, checking all the classes that you want match.

$("#test").is(".a1,.a2,.a3,.a4,.a5") 

Answer 2

You can use the hasClass function.

var test = $('#test'); if(test.hasClass('a1') || test.hasClass('a2') || test.hasClass('a3') ...) { ... }
