我在使用drafjs插件(即编辑器)时遇到了问题,当我在编辑器中键入内容时,它会跳到文本的开头。我已经找到了How to stop DraftJS cursor jumping to beginning of text?这个解决方案,但是它与我的代码有点不同,此外,我还使用React Hooks的新功能制作了该组件。拜托,您能帮我解决这个问题吗?

import {
  EditorState, ContentState, convertToRaw,
} from 'draft-js'
import { Editor } from 'react-draft-wysiwyg'
import 'react-draft-wysiwyg/dist/react-draft-wysiwyg.css'
import draftToHtml from 'draftjs-to-html'
import htmlToDraft from 'html-to-draftjs'

export default ({ value, onChange }) => {
  const [editorState, setEditorState] = useState(EditorState.createEmpty())

  useEffect(() => {
    setEditorState(
      EditorState.push(
        editorState,
        ContentState.createFromBlockArray(
          htmlToDraft(value || ''),
        ),
      ),
    )
  }, [value])

  return (
    <div className="rich-editor">
      <Editor
        editorState={editorState}
        onEditorStateChange={onEditorStateChange}
        toolbar={{
          options: ['inline'],
          inline: {
            options: ['bold', 'italic', 'underline'],
          },
        }}
      />
    </div>
  )

  function onEditorStateChange(es) {
    setEditorState(es)

    const html = draftToHtml(convertToRaw(es.getCurrentContent()))
    if (value !== html) {
      onChange({ target: { name: 'text', value: html } })
    }
  }
}

好吧,我有点弄清楚自己。但是,这不是最佳解决方案。基本上,我将更新后的文本转换为HTML类型,然后将值与转换后的darft.js editorState进行比较。不久,这是我的代码,如果将来对任何人有帮助的话

import React, { useEffect, useState } from 'react'
import {
  EditorState, ContentState, convertToRaw,
} from 'draft-js'
import { Editor } from 'react-draft-wysiwyg'
import 'react-draft-wysiwyg/dist/react-draft-wysiwyg.css'
import draftToHtml from 'draftjs-to-html'
import htmlToDraft from 'html-to-draftjs'

export default ({ value, onChange }) => {
  const [editorState, setEditorState] = useState(EditorState.createEmpty())

  useEffect(() => {
    if (toHtml(editorState) === value) return //added

    setEditorState(
      EditorState.push(
        editorState,
        ContentState.createFromBlockArray(
          htmlToDraft(value || ''),
        ),
      ),
    )
  }, [value])

  return (
    <div className="rich-editor">
      <Editor
        editorState={editorState}
        onEditorStateChange={onEditorStateChange}
        toolbar={{
          options: ['inline'],
          inline: {
            options: ['bold', 'italic', 'underline'],
          },
        }}
      />
    </div>
  )

  function onEditorStateChange(es) {
    setEditorState(es)
    const html = toHtml(es) //added
    if (value !== html) {
      onChange({ target: { name: 'text', value: html } })
    }
  }

  function toHtml(es) {
    return draftToHtml(convertToRaw(es.getCurrentContent())) // added
  }
}
