大哥
这你都搞不顶啊
没加连接怎么能小行啊
在script里面加一行
location.herf=http;//什么东西。什么

孟夫子，你的代码只在刷新的时候变颜色啊，点击按钮都没反应的？

这样子，更象你要的：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title></title>
</head>
<body>
<input type=hidden id=showButton1 value="true">
<button id=button1 style="display:none">test1</button>
<input type=hidden id=showButton2 value="false">
<button id=button2 style="display:none">test2</button>
<input type=hidden id=showButton3 value="true">
<button id=button3 style="display:none">test3</button>
<script>
if (showButton1.value == "true") button1.style.display="";
if (showButton2.value == "true") button2.style.display="";
if (showButton3.value == "true") button3.style.display="";
</script>
</body>
</html>
其中hidden 对象的value由你在服务器端判断了权限以后设置。

是做B/S结构的程序把。可以动态生成网页的时候决定按钮要不要显示的啊，就是把所以的按钮都做上去，然后全部 style="display:none"，然后在生成页面的时候把用户的权限放到页面上（比如放到hidden 框里），在页面上的javascript 里面判断对应的hidden里面的值来决定要不要把相应的按钮显示出来button.style.display=""
如：
<input type=hidden id=showButton1 value="true">
<button id=button1 style="display:none">test</button>
<script>
if (showButton1.value == "true") button1.style.display="";
</script>
以上调试通过

办法一：随机颜色或背景图等
办法二：结合服务器端代码，生成不同的样子。
