This is the expected behavior. The selector '.myClass a' describes an A tag
being a descendant of a tag with the class myClass. is() doesn't work on a
relationship as the result is ambiguous. To check if this element is an A
tag that is a descendant of of a tag with class myClass, maybe try:
if($(this).filter('a').parents('.myClass').length > 0) {...}
Or, in your case:
if($(target).is('a')) {
if($(target).parents('.myClass').length > 0) {
}
if($(target).parents('.myOtherClass').length > 0) {
}
}
Or, if you just want to check if this is a child of an element with a
particular class, you could do:
var $parent = $(target).parent();
if($parent.is('.myClass')) {...}
if($parent.is('.myOtherClass')) {...}
