Здравствуйте, Koss87, Вы писали:
K>выложи полностью всю страницу аспх и цс, а также яваскрипты..
Во-первых хотел выразить тебе блогадарность за помощь
Я попытался присвоить event "onclick" в функции buildNodeContent так чтоб при нажатии на элементы меню(На "add child", на "update version", на "history") сработал alert,
но alert срабатывает только когда я нажимаю на Actions. Как же мне сделать?
