    flatten the array and use indexOf ...

    var foo = ['.com','.net','.org','.biz','.coop','.info','.museum','.name','.pro' ,'.edu','.gov','.int','.mil','.ac','.ad','.ae','.af','.ag','.ai','.al'], fooFlat = foo.join(","), isAllowed = function(what) {
    return (foo.indexOf(what) != -1) ? true : false;
};  

// example use...
if (isAllowed(".com")) {
    alert("found .com");
}

if (isAllowed(".it")) {
    alert("found .it");
}
else {
    alert("not found .it!");
}

alert(((isAllowed(".org")) ? "found" : "not found") + " .org");
