If you want to match only elements with both classes (an intersection, like a logical AND), just write the selectors together without spaces in between:
$('.a.b')
The order is not relevant, so you can also swap the classes:
$('.b.a')
So to match a div element that has an ID of a with classes b and c, you would write:
$('div#a.b.c')
(In practice, you most likely don't need to get that specific, and an ID or class selector by itself is usually enough: $('#a').)
@Flater: It was just for the sake of example. But it might be useful if the classes
bandcare dynamically added, and you only want to select the element if it has those classes.@Shimmy: Yes. A space between two selectors means you're searching for descendants; i.e.
.a .bsearches for elements with classbthat are descendants of an element with classa. So something likediv awill only returnaelements that are inside adivelement.
