Sanity CMS 的前端未应用文本突出显示

Question

我正在尝试使用 Sanity Headless CMS 和前端 React 创建博客。

我做了一个装饰器来突出显示文本。如下图所示，在编辑器中，突出显示的文本具有黄色背景色。但是，我没有在我的 React 前端看到黄色突出显示。

我错过了什么？

代码片段如下： sanityblog/schemas/blockContent.js

import React from "react";

/**
 * This is the schema definition for the rich text fields used for
 * for this blog studio. When you import it in schemas.js it can be
 * reused in other parts of the studio with:
 *  {
 *    name: 'someName',
 *    title: 'Some title',
 *    type: 'blockContent'
 *  }
 */

const highlightRender = (props) => (
  <span style={{ backgroundColor: "yellow" }}>{props.children}</span>
);

export default {
  title: "Block Content",
  name: "blockContent",
  type: "array",
  of: [
    {
      title: "Block",
      type: "block",
      // Styles let you set what your user can mark up blocks with. These
      // correspond with HTML tags, but you can set any title or value
      // you want and decide how you want to deal with it where you want to
      // use your content.
      styles: [
        { title: "Normal", value: "normal" },
        { title: "H1", value: "h1" },
        { title: "H2", value: "h2" },
        { title: "H3", value: "h3" },
        { title: "H4", value: "h4" },
        { title: "Quote", value: "blockquote" },
      ],
      lists: [{ title: "Bullet", value: "bullet" }],
      // Marks let you mark up inline text in the block editor.
      marks: {
        // Decorators usually describe a single property – e.g. a typographic
        // preference or highlighting by editors.
        decorators: [
          { title: "Strong", value: "strong" },
          { title: "Emphasis", value: "em" },
          {
            title: "Highlight",
            value: "highlight",
            blockEditor: {
              icon: () => "H",
              render: highlightRender,
            },
          },
        ],
        // Annotations can be any object structure – e.g. a link or a footnote.
        annotations: [
          {
            title: "URL",
            name: "link",
            type: "object",
            fields: [
              {
                title: "URL",
                name: "href",
                type: "url",
              },
              {
                title: "Open in new tab",
                name: "blank",
                description: "Read https://css-tricks.com/use-target_blank/",
                type: "boolean",
              },
            ],
          },
        ],
      },
    },
    // You can add additional types here. Note that you can't use
    // primitive types such as 'string' and 'number' in the same array
    // as a block type.
    {
      type: "image",
      options: { hotspot: true },
    },

    {
      type: "code",
    },
  ],
};

您需要序列化数据。

您已经为代码编辑器 window 执行了此操作，在您当前的序列化程序中，您说“如果类型是代码，运行此组件”。

你也需要为语法高亮器做这个，也许这样的事情可以工作（还没有测试过）

marks: {
  highlight: ({ children }) => {
    return <HighLightComponent children={children} />;
  },
},
