使用js实现文字颜色不停变化的链接

<script language="JavaScript">
<!--document.linkColor是设置链接的颜色
function IArray() {
 for (var i = 0; i < IArray.arguments.length; i++)
 {
 this[i] = IArray.arguments[i];
 }
 this.length = IArray.arguments.length;
}

var colors = new IArray("#ff0000","#0000ff","#00ffff","#cccccc","#000000","#ffff00","#ff0000");
delay = 1.;
link = 0;
vlink = 0;
function linkChange() {
link = ((link+1)%colors.length);
vlink = ((vlink+1)%colors.length);
document.linkColor = colors[link];
document.vlinkColor = colors[vlink];
setTimeout("linkChange()",delay*1000);
}
linkChange();
-->
</script>
