Answer 1

不知道怎么隐藏按钮？
获取ID，getElementByID，然后隐藏就是了，楼主不可能不会的把或者你不同的用户登录后，这时你动态创建一个button，然后设置根据用户登录的数据来设置这个按钮的不同的属性。不知道我有没有误会楼主的意思

Answer 2

你不妨四个按钮开始都显示 然后根据在你的arry种增加一个标志 表示显示哪一个按钮 隐藏哪些按钮
按钮隐藏和显示
<input type= "button" id="btn" style="display:none"> 这是隐藏的
要设置成显示的
document.getElementById('btn').style.display = "";//显示
document.getElementById('btn').style.display = "none";//隐藏
