如何在ReactJS中获取contentEditable Input的初始值和setState值?

标签: javascript reactjs contenteditable

  

我正在尝试使用contentEditable div构建评论框,并具有   以下问题:

     
      
  1. 无法获取text属性的初始值。
  2.   
  3. 未从contentEditable获取setState值。
  4.   
  5. 表情符号存在问题,使用输入元素时可以正常工作,但不能与contentEditable一起使用。
  6.   
     

使用下面提供的代码,当console.log出现时,我变得不确定,   不知道我在想什么。

     

预期结果。

     
      
  1. 从contentEditable中获取键入的值,包括表情符号。
  2.   
// Content Input Model

import React, { Fragment } from 'react'
import '../../assets/css/comment.css'

const ContentInput = ({valueChange,contentInputId,ref,onClick,onPhClick,placeholder,  ...props }) => {
    return (
        <Fragment>
      <div
          spellCheck="false"
          role="textbox"
          id={contentInputId}
          ref={ref}
          contentEditable="true"
          onChange={valueChange}
          aria-multiline="true"
          data-placeholder={placeholder}
          {...props}
      />
            <div className="comment_submit_button" onClick={onClick}>

onInput上使用ContentInput而不是onChange

然后在e.target.innerHTML上使用desChange而不是e.target.value

contentEditable事件应为“ onInput” Content Editable change events
