我解决了这个问题，希望这与你预期的类似 首先，修复你的 css 代码：

• 你将 class tab-button-active 添加到你的 css 代码中，以便在单击时激活链接：

  .tab-button-active { color: var(--c-accent-primary) !important; border-bottom: 3px solid var(--c-accent-primary) !important;

• 在内容激活时，将你的 css 代码更新为内容和代码。这将类似于代码并使用 display: flex !important 显示 none 和 active，代码如下：

  .content {
  border-top: 1px solid var(--c-border-primary);
  margin-top: 2rem;
  display: none;
  }
  

  .content-active { display: flex !important;

其次，修复 javascript 代码中的一些错误：

• 您可以用 querySelectorAll 替换 querySelector，以便用查询选择所有元素，以下是错误代码：

  menuBar.querySelector(".tab-button").forEach(link => {
  link.classList.remove("tabs-button-active");
  })
  
  tabsContainer.querySelector(".content").forEach(tab => {
  tab.classList.remove("content-active");
  })
  

• 一些拼写错误：“tab-button-active”类似于您在活动时添加的 className，而不是“tabs-button-active”

  link.classList.remove("tabs-button-active");
  

• tabsContainer 不包含 tab-button，因此您无法在此上使用 querySelector，下面是修复代码：

  document.addEventListener("DOMContentLoaded", () => { switchTabs();

  document.querySelectorAll(".content").forEach(tabsContainer => {
  
  document.querySelector(".horizo​​ntal-tabs .tab-button").click()
  })
  

  });

这是我的代码，希望对您有用：

function switchTabs() {
  document.querySelectorAll(".tab-button").forEach(link => {

link.addEventListener("click", () => {
  const menuBar = link.parentElement;
  const tabsContainer = menuBar.parentElement;
  const tabNumber = link.dataset.forTab;
const tabToActivate = tabsContainer.querySelector(`[data-tab="${tabNumber}"]`)



  menuBar.querySelectorAll(".tab-button").forEach(link => {

    link.classList.remove("tab-button-active");
  })

  tabsContainer.querySelectorAll(".content").forEach(tab => {
    tab.classList.remove("content-active");
  })
  link.classList.add("tab-button-active");
 
  tabToActivate.classList.add("content-active");
});
  });
}

document.addEventListener("DOMContentLoaded", () => {
  switchTabs();

  document.querySelectorAll(".content").forEach(tabsContainer => {

document.querySelector(".horizontal-tabs .tab-button").click()
  })
});

此处出错：

document.querySelectorAll(".content").forEach(tabsContainer => {
  console.log(tabsContainer);
  tabsContainer.querySelector(".horizontal-tabs .tab-button").click();
})

您的 content 类中没有 horizo​​ntal-tabs 类。

因此，当您使用 tabsContainer.querySelector(".horizo​​ntal-tabs .tab-button") 时，您得到的是空元素。 显然，您在空元素上调用 click 函数会引发错误。

如果您不确定选择了哪些元素，只需将其打印在控制台上即可。

我不确定您到底想要做什么，但我一直坚持到所有错误都已解决。

首先，一个小问题，您忘记结束强元素：

<!-- old code -->
<a style="font-size: 45px; color: #A388E7;" class="navbar-brand" href="#"><strong>StudioPick</a>
<!-- new code -->
<a style="font-size: 45px; color: #A388E7;" class="navbar-brand" href="#"><strong>StudioPick</strong></a>

如果您打算对它们执行 forEach ，则应将上述内容更改为 querySelectorAll ，因为 querySelector 仅返回一个元素。

//old code
menuBar.querySelector(".tab-button").forEach(link => {
      link.classList.remove("tabs-button-active");
})

tabsContainer.querySelector(".content").forEach(tab => {
      tab.classList.remove("content-active");
})

//new code
menuBar.querySelectorAll(".tab-button").forEach(link => {
      link.classList.remove("tabs-button-active");
})

tabsContainer.querySelectorAll(".content").forEach(tab => {
      tab.classList.remove("content-active");
})

您应该使用 document 而不是 tabsContainer ，因为 tabsContainer 下没有 horizo​​ntal-tabs ，这就是您收到最初谈论的空问题的原因。

//old code
document.querySelectorAll(".content").forEach(tabsContainer => {
    tabsContainer.querySelector(".horizontal-tabs .tab-button").click();
})

//new code
document.querySelectorAll(".content").forEach(tabsContainer => {
    document.querySelector(".horizontal-tabs .tab-button").click();
})

以下是修复后的代码：

function switchTabs(){
document.querySelectorAll(".tab-button").forEach((link) => {
    link.addEventListener("click", () => {
        const menuBar = link.parentElement;
        const tabsContainer = menuBar.parentElement;
        const tabNumber = link.dataset.forTab;
        const tabToActivate = tabsContainer.querySelector(`.content[data-tab="${tabNumber}"]`);

        menuBar.querySelectorAll(".tab-button").forEach(link => {
            link.classList.remove("tabs-button-active");
        })

        tabsContainer.querySelectorAll(".content").forEach(tab => {
            tab.classList.remove("content-active");
        })

        link.classList.add(".tab-button-active");
        tabToActivate.classList.add(".content-active");
    });
});
}

document.addEventListener("DOMContentLoaded", () => {
switchTabs();

document.querySelectorAll(".content").forEach(tabsContainer => {
    document.querySelector(".horizontal-tabs .tab-button").click();
})
});
