Hej
Har ett mycket bra script som fade:ar bilder mycket snyggt, nu undrar jag om man kan göra om det så man kan fade en div med 2st bildknappar i utan att det hoppar när man har mouseover på bildknappen.
Js koden:
/****** User may alter these to change the fade effect ********/
var FadeInStep = 10;
var FadeOutStep = 10;
/****** Don't alter anything else **************/
if(!window.JSFX)
JSFX=new Object();
JSFX.RolloverObjects=new Array();
JSFX.Rollover = function(name, img)
{
JSFX.RolloverObjects[name]=new Image();
JSFX.RolloverObjects[name].img_src = img;
if(!JSFX.Rollover.postLoad)
JSFX.RolloverObjects[name].src = img;
}
JSFX.Rollover.postLoad = false;
JSFX.Rollover.loadImages = function()
{
var i;
for(i in JSFX.RolloverObjects)
{
r=JSFX.RolloverObjects[i];
r.src=r.img_src;
}
}
JSFX.Rollover.error = function(n)
{
alert("JSFX.Rollover - An Error has been detected\n"
+ "----------------------------------\n"
+ "You must define a JSFX.Rollover in your document\n"
+ "JSFX.Rollover(\""+n+"\",\"your_on_img.gif\")\n"
+ "(check the spelling of your JSFX.Rollovers)");
}

Eller har du ett färdigt fade script där man fadar en div så vore det ju kanon, har kollat runt och har inte hittat något som funkar tillräckligt bra!
