но не работает.

А что она должна делать?
Я так понял, что должно что то подсвечиваться при наведении
и увеличиваться/уменьшаться при нажатии кнопок
Вы каким то образом меняете координаты у area
coords[ n ][ m ] *= x;
причем x = img.offsetWidth / previousWidth;
а previousWidth вначале почему то 128 (а почему?)
А масштаб меняете по формулам
img.width = min_width + (max_width - min_width) * ratio / max_ratio;
img.height = img.width * (max_height / max_width);
Я не знаю, правильные они или нет. Вы их придумали, вы и смотрите. |

А можно сделать что бы вот этот скрипт отслеживал изменение экрана
<script>
$("img[usemap]").mapster({
scaleMap: true,
fill: true,
fillColor: '2CA7DC',
fillOpacity: 0.75,
});
</script>

Но скрипт который вы писали для приближение и отдаление он передвигает карту а не масштабирует ее.

Ну вы хоть скопируйте сообщение об ошибке.
Или сделайте скрипт запускаемым. |

Понял что я не решу проблемы которые были в скриптах выше, стал искать другие решение.
Нашел. ПОМОГИТЕ.
Все работает так как нужно.
Но мне бы хотелось что бы когда карта подвергается зуму или перемешается она была в границах класса .blok_map (если начать двигать карту или уменьшать то видно как она покидает границы)
Если что код взял от сюда
