Ciao!! :byebye:
Mi servirebbe un aiutino per fare in modo che in questo menu (vedi javascript sotto) quando passo cn il mouse sopra alla "miaimmagine", questa si scambi con un altra immagine e quando tolgo il mouse di li sopra che ritorni la "miaimmagine"...
In questo modo riuscirei a fare un effetto tipo tasto selezionato...
Grazie in anticipo!

Codice:
<style type="text/css">

#dropmenudiv{
border-left:1px solid black; border-right:1px solid black; border-top:1px solid black; border-bottom:0px solid black; position:absolute;
background-color: #E3FFB0;
line-height:18px;
z-index:100; font-style:normal; font-variant:normal; font-weight:normal; font-size:12px; font-family:Verdana
}

#dropmenudiv a{
width: 100%;
display: block;
text-indent: 3px;
border-bottom: 1px solid black;
padding: 1px 0;
text-decoration: none;
font-weight: bold;
}

#dropmenudiv a:hover{ /*hover background color*/
background-color: #C7FF5E;
}

/* Sample CSS definition for the example list. Remove if desired */
.navlist li {

Ci ho provato e ho modificato così il codice...

text-indent: 3px;

<body >
<a href="#" onMouseover="dropdownmenu(this, event, menu1, '165px')" onMouseout="delayhidemenu()">Link interessanti</a><p><br />


<img    src="images/INDEX/s-testata-vertical.jpg"    onmouseover="this.src='images/INDEX/testata.jpg'"    onmouseout="this.src='images/INDEX/s-testata-vertical.jpg'" width="150" height="23">
</p>
</body>
</html>
Però mi da un errore nel passaggio
HTML:
onmouseover="this.src='images/INDEX/testata.jpg'
xk nn gli va bene l'apostrofo '...
Ho provato a sostituirlo con " ma mi da altri problemi...

Quello che non capisco è perchè nel javascript non funzioni, mentre il codice che ho riscritto a fondo pagina funziona senza dare errori...
HELP ME, c sto partendo di testa :crying: !
 
Che ti dia questo errore è normale, perchè tu la stringa la costruisci entro apici singoli, quindi, inserendo altri apici singoli all'interno di essa è come se la chiudessi ;)

Per porre rimedio, devi inserire davanti gli apici singoli contenuti nella stringa il backslash:
Codice:
...onmouseover="this.src=[COLOR="red"][B]\[/B][/COLOR]'images/INDEX/testata.jpg[B][COLOR="Red"]\[/COLOR][/B]'...

In questo modo il compilatore capisce che l'apice singolo contenuto dopo la barra \ fa parte della stringa.
