要完成此效果把如下代码加入到区域中 <script language="JavaScript"> var COLOR = 999999 var woot = 0 function stoploop() { document.bgColor = '#336699'; clearTimeout(loopID); } function loopBackground() { if (COLOR > 0) { document.bgColor = '#' + COLOR COLOR -= 111111 loopID = setTimeout("loopBackground()",1) } else { document.bgColor = '#336699' woot += 10 COLOR = 999999 COLOR -= woot loopID = setTimeout("loopBackground()",1) } } </script>
