}
document.bgColor=col[pos];

但还有个问题，就是
var col=new initArray( "4b ", "5b ", "8b ", "8b ");
后面的"4b""5b""8b""8b"是什么意思？书上没有说。把值改掉，好像也没有什么效果。

楼主的代码没问题，只是你没调用他的方法
在<body>中写
<BODY bgcolor="#ffffff" onload="chgCol()">
在<body>中写
<BODY bgcolor="#ffffff" onload="chgCol()">
js实现点击按钮变换背景颜色 function aa(){ document.bgColor="Orange"; } function change(c){ document.bgColor=c; }
