Frozen Coyote,

var apr = "It's a dark april night",
    may = "It's a bright may day",
    jun = "It's a bright june day",
    jul = "It's a bright july day";

var pattern = (".* bright(?!june).* day.*");

apr.match(pattern) ? alert("Gotcha!") : alert("Sorry");
may.match(pattern) ? alert("Gotcha!") : alert("Sorry");
jun.match(pattern) ? alert("Gotcha!") : alert("Sorry");
jul.match(pattern) ? alert("Gotcha!") : alert("Sorry");

Я правильно понял? Аналогичный результат нужен?
