> Er der en side vi kan se resultatet på?
Næ, beklager. Men jeg kan forklare lidt mere:
Jeg har fnedenstående funktion liggende i en common.php-fil, der
så kaldes fra en anden php-fil med GenerateHTMLHeader();
Dele af menuen udskrives også(baren vises, men uden felter), men
stopper altså ved funktionskaldet til writeMenus().
Og jeg kalder en tilsvarende GenerateHTMLFooter, der afslutter
html-koden. Fidusen skulle så være, at jeg kan kalde de 2
funktioner fra forskellige sider, men med forskelligt indhold
midt på siden.
Javascriptet er jeg ikke mester for, og det er ikke rettet helt
til, men det virker ok til testformål på en almindelig html-side.
Gør det spørgsmålet mere klart?
