How can I change the visible / hidden property of a button with javascript?

在我的页面上，我有以下主题更改按钮：

<button class="small theme" name="darkBlue" onclick="setThemeColor(this)">
   <span style="color: white; font-weight: bold;">#</span>
</button>
<button class="small theme" name="black" onclick="setThemeColor(this)">
   <span style="color:black; font-weight:bold;">#</span>
</button>

我有这个javascript：

   <script type="text/javascript">
      if (localStorage.themeColor) {
         document.getElementsByTagName('html')[0].className = localStorage.themeColor;
      }
      function setThemeColor(button) {
         localStorage.themeColor = button.name;
         document.getElementsByTagName('html')[0].className = button.name;
         var themeButtons = document.querySelectorAll(".theme");
         for (var themeButton in themeButtons) {
             themeButtons[themeButton].disabled = false;
         }
        button.disabled = true;
      }
   </script>

这总是显示两个按钮，但我想这样而不是当前按钮被禁用，则按钮不可见。有人可以建议我该怎么做？

function setThemeColor(button) {
    localStorage.themeColor = button.name;
    document.getElementsByTagName('html')[0].className = button.name;
    var themeButtons = document.querySelectorAll(".theme");
    for (var themeButton in themeButtons) {
        themeButtons[themeButton].disabled = false; // Re-included from original code
        themeButtons[themeButton].style.visibility="visible" // Corrected from original answer
    }
    button.disabled = true;
    button.style.visibility="hidden" // Added/Moved from above after noted I'd messed up the logic
}
