ho due file js che fanno funzionare un menu a tendina...
su ogni voce del menu a tendina si può prevedere un link ad una pagina diversa...
il link funziona bene ma mi apre un'altra pagina (frame nuova finestra _blank)...
vorrei invece che la pagina a cui si linka fosse aperta all'interno del frame principale dell'home page... ma non ci riesco...
posto i due js:
1° JS
arMenu1 = new Array(
"Bobine","http://",0,
"GESI","http://",0,
"Sistema","http://",0,
"Acquisti","http://",0,
"CARMEN","http://",0,
"Qualità","http://",0,
"MT","http://",0,
"Assistenza","http://",0,
"Rilevazione","http://",0
)
arMenu1_1 = new Array(
"link1_1","http://www.homepage2.net",0
)
arMenu1_2 = new Array(
"Cabine","http://www.homepage.com",0
)
