switch(state)
{
divstyles[0].fontsize= "x-small";
divstyles[0].fontStyle = "italic";
divstyles[1].fontsize = "medium";
divStyles[1].fontVariant = "small-caps";
divstyles[2].fontsize ="x=large";
divstyles[2].fontFamily ="courier";

}
switch()后面要用case state="state.."

我不知道你的state是什么样的我给你改成下面这样就可以了：
function applyDHTML(){
if(browser=="unknown")
{
alert("sorry your browser does not provide sufficient dhtml suppport to run this example.")
return
}
switch(state)
{
case "1":divstyles[0].fontsize= "x-small";break;
case "2": divstyles[0].fontStyle = "italic";break;
case "3": divstyles[1].fontsize = "medium";break;
case "4": divStyles[1].fontVariant = "small-caps";break;
case "4": divstyles[2].fontsize ="x=large";break;
case "4":divstyles[2].fontFamily ="courier";break;

}
++state;
}
