javascript - 更改页面 div 中的文本

Question

我正在尝试制作类似文本旋转器的东西。 当我点击关于选项卡时，我只想显示关于信息，当我点击项目时，我想删除关于文本并将其替换为项目文本，并与我实际按下的其他文本相同。

我可以让它一个接一个地出现。但这不是我想要的。希望你们明白我想做什么。

不要给我写!请告诉我应该在哪里寻找它，我应该使用循环吗？

你快到了。请记住，您需要隐藏所有不想在每次点击时显示的段落。所以循环是个好主意。 然后显示唯一。

这是一个代码片段，它做的事情与您的方法略有不同，以防您遇到困难。继续你的解决方案!

document.getElementById('tablist').addEventListener('click', function(e){
    const tabs = ['tab1', 'tab2'];
    const ti = tabs.indexOf(e.target.id);
    if(ti !== false){
      for(let i = 0; i < tabs.length; i += 1) {
        if(ti !== i){
          document.getElementById(tabs[i]+'Txt').style.display = 'none';
        }
      }
      document.getElementById(tabs[ti]+'Txt').style.display = 'block';
    }
});

  .hiddenText {
    display: none;
  }

<ul id="tablist">
<li id="tab1">tab1</li>
<li id="tab2">tab2</li>
</ul>

<p id="tab1Txt" class="hiddenText">
This is tab1Txt.
</p>

<p id="tab2Txt" class="hiddenText">
This is tab2Txt.
</p>
