英文:

Bootstrap List Group Nested Links 'freezes" and won't work after first click

问题

我正在尝试在HTML中使用Bootstrap List-group类创建页面导航功能。

然而，在用户第一次点击嵌套链接'Link 1'和'Link 2'之后，它们会冻结。

该功能应该如何工作：

当我点击“Home”时，显示“Link 1”，当我进一步点击“Link 1”时，显示“Page 1”。

同样，当我点击“Profile”时，显示“Link 2”，当我进一步点击“Link 2”时，显示“Page 2”。

链接“Link 1”和“Link 2”在第一次点击时工作正常，但在第二次点击时会“冻结”。

你能帮我找到问题吗？

谢谢！

英文:

I am trying to create a page navigation feature in HTML using the Bootstrap List-group class.

However, the nested links 'Link 1' and 'Link 2' freeze after a user clicks them the first time.

How the feature is supposed to work:

When I click Home, show link 1 and when I further click Link 1, show Page 1.

Likewise, when I click Profile, show link 2, and when I further click Link 2, show Page 2.

The links link 1 and link 2 work fine on first click, but 'freeze' and won't work on second click.

Could you help me spot the issue!

Thanks!

问题是因为点击选项卡后，选项卡保持活动状态。

解决方法是使用JavaScript并执行以下操作：

每次点击“Home”选项卡时，从HTML类active中移除Link 1选项卡。
每次点击“Profile”选项卡时，从HTML类active中移除Link 2选项卡。

请参见下面的代码片段。

const homeTab = document.querySelector("#list-home-list");
const profileTab = document.querySelector("#list-profile-list");

const link1 = document.querySelector("#link-1-tab .list-group-item");
const link2 = document.querySelector("#link-2-tab .list-group-item");

homeTab.addEventListener("click", () => {
  link1.classList.remove("active");
});

profileTab.addEventListener("click", () => {
  link2.classList.remove("active");
});

英文:

The problem is caused because tabs stay active once you click them for the first time.

The solution is to use JavaScript and do the following:

Remove the HTML class active from the Link 1 tab every time the Home tab is clicked.
Remove the HTML class active from the Link 2 tab every time the Profile tab is clicked.

See the snippet below.

const homeTab = document.querySelector(&quot;#list-home-list&quot;);
const profileTab = document.querySelector(&quot;#list-profile-list&quot;);
const link1 = document.querySelector(&quot;#link-1-tab .list-group-item&quot;);
const link2 = document.querySelector(&quot;#link-2-tab .list-group-item&quot;);
homeTab.addEventListener(&quot;click&quot;, () =&gt; {
link1.classList.remove(&quot;active&quot;);
});
profileTab.addEventListener(&quot;click&quot;, () =&gt; {
link2.classList.remove(&quot;active&quot;);
});
