Tailwind Color Classes在NextJS和React Vite中单击按钮时无法正常工作

所以我有一个组件,基本上演示了Tailwind + React中的“文本渐变”效果。我有4个选择下拉菜单和一个“随机”按钮。单击按钮或从下拉列表中选择任何内容后,将预览更改。
现在,我第一次遇到了一个问题,颜色类没有被正确应用。我的意思是,它们确实出现在标记的className属性中--但是这些类很少在屏幕上实现。未应用的颜色也不会显示在开发工具->样式边栏中。

我已经录制了一个2分钟的视频-在这里:https://streamable.com/3auz04

正如你所看到的,我试图不断地生成结果,大多数时候,文本是透明的/没有颜色被应用。
现在-我知道你一定认为,也许类是错误的?在任何时候,如果我复制类并转到play.tailwindcss.com-它都有效。

<h2 class="bg-gradient-to-r from-pink-700 via-yellow-800 to-lime-500 bg-clip-text text-center text-7xl font-bold text-transparent">Whats Up</h2>

字符串
下面是一个在PreviewText.jsx中不起作用的类的例子--但是在play.tailwindcss.com上起作用--基本上证明了Tailwind类没有任何问题。
下面是我的相关代码:
梯度使用状态变量:

const [gradient, setGradient] = useState({
direction: "bg-gradient-to-tl",
fromColor: "from-slate-800",
viaColor: "via-violet-500",
toColor: "to-zinc-400",

});


RandomizeGradient函数:

const randomizeTextGradient = () => {
    const randomDirection =
      gradientDirections[Math.floor(Math.random() * gradientDirections.length)]
        .value;
    const randomFromColor =
      fromArray[Math.floor(Math.random() * fromArray.length)].value;
    const randomViaColor =
      viaArray[Math.floor(Math.random() * viaArray.length)].value;
    const randomToColor =
      toArray[Math.floor(Math.random() * toArray.length)].value;

    const newGradient = {
      direction: randomDirection,
      fromColor: randomFromColor,
      viaColor: randomViaColor,
      toColor: randomToColor,
    };

    setGradient(newGradient);
      };


TextGradient.tsx:

<section className="text-white bg-transparent border-t border-b border-zinc-800 my-6">

如果你好奇的话,这里是我如何生成类的:

const colors = [
    "slate",
    "gray",
    "zinc",
    "neutral",
    "stone",
    "red",
    "orange",
    "amber",
    "yellow",
    "lime",
    "green",
    "emerald",
    "teal",
    "cyan",
    "sky",
    "blue",
    "indigo",
    "violet",
    "purple",
    "fuchsia",
    "pink",
    "rose",
  ];

  const numbers = [100, 200, 300, 400, 500, 600, 700, 800, 900];

  let fromArray = [];
  let viaArray = [];
  let toArray = [];

  colors.forEach((color) => {
    numbers.forEach((number) => {
      let fromValueLabel = `from-${color}-${number}`;
      let viaValueLabel = `via-${color}-${number}`;
      let toValueLabel = `to-${color}-${number}`;
      fromArray.push({ value: fromValueLabel, label: fromValueLabel });
      viaArray.push({ value: viaValueLabel, label: viaValueLabel });
      toArray.push({ value: toValueLabel, label: toValueLabel });
    });
  });


我已经试着修复这个2天了,但没有运气。如有帮助,不胜感激。我已经在NextJS和React Vite中测试了这段代码。

正如@Danila所提到的,您没有完全遵循动态类名的文档。文档的主要观点是:
不要动态构造类名

<div class="text-{{ error ? 'red' : 'green' }}-600"></div>

字符串
在上面的例子中,字符串text-red-600和text-green-600不存在,所以Tailwind不会生成这些类。
相反,请确保您使用的任何类名都完整存在:
始终使用完整的类名

<div class="{{ error ? 'text-red-600' : 'text-green-600' }}"></div>
