所以我尝试只打印一次一些标签，每个循环有四个标签。

所以本质上，我正在尝试遍历并为每个标签打印一次标签。

第二个是每个循环打印四个标签。

为了更好地解释这里有一些图片。

这是我的代码

最佳答案

这绝不是复制粘贴解决方案。您的代码中有一些变量，我不知道它们包含什么，但这应该作为解决方案的潜在想法。本质上，所需的结果是一个数据“表”。是使用表格还是 div 来构造 HTML 结构由您决定。您可以使用诸如 bootstrap 或 foundation 或其他 CSS 框架提供的布局。此示例仅使用一个表来提供结构。您需要将答案标签绘制到一个容器中，例如用于在表头中进行迭代的数组。然后，您可以只用输入来呈现每个答案，而不用关心是否在每次迭代时打印它。希望这对您有所帮助!
