blocks|key|4642288|text|这可能不是你正在寻找的答案，但我自己也在努力解决这个问题，并对建议的答案有问题，我决定让它变得不受控制。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4642289|当editable属性为false时，我会按原样使用text属性，但当它为true时，我会切换到编辑模式，在该模式下text不起作用(但至少浏览器不会崩溃)。在此期间，控件将触发onChange。最后，当我将editable改回false时，它会用传递给text的内容填充HTML|offset|length|style|CODE|4642290|/**+@jsx+React.DOM+*/

<p>This probably isn't exactly the answer you're looking for, but having struggled with this myself and having issues with suggested answers, I decided to make it uncontrolled instead.</p>

<p>When <code>editable</code> prop is <code>false</code>, I use <code>text</code> prop as is, but when it is <code>true</code>, I switch to editing mode in which <code>text</code> has no effect (but at least browser doesn't freak out). During this time <code>onChange</code> are fired by the control. Finally, when I change <code>editable</code> back to <code>false</code>, it fills HTML with whatever was passed in <code>text</code>:</p>

<pre><code>/** @jsx React.DOM */
'use strict';

var React = require('react'),
    escapeTextForBrowser = require('react/lib/escapeTextForBrowser'),
    { PropTypes } = React;

var UncontrolledContentEditable = React.createClass({

<p>I suggest using a mutationObserver to do this. It gives you a lot more control over what is going on. It also gives you more details on how the browse interprets all the keystrokes</p>

<p>Here in TypeScript</p>

<pre><code>import * as React from 'react';

export default class Editor extends React.Component {
    private _root: HTMLDivElement; // Ref to the editable div
    private _mutationObserver: MutationObserver; // Modifications observer
    private _innerTextBuffer: string; // Stores the last printed value

    public componentDidMount() {
        this._root.contentEditable = "true";
        this._mutationObserver = new MutationObserver(this.onContentChange);
        this._mutationObserver.observe(this._root, {
            childList: true, // To check for new lines
            subtree: true, // To check for nested elements
            characterData: true // To check for text modifications
        });
    }

    public render() {
        return (
            &lt;div ref={this.onRootRef}&gt;
                Modify the text here ...
            &lt;/div&gt;
        );
    }

    private onContentChange: MutationCallback = (mutations: MutationRecord[]) =&gt; {
        mutations.forEach(() =&gt; {
            // Get the text from the editable div
            // (Use innerHTML to get the HTML)
            const {innerText} = this._root; 

            // Content changed will be triggered several times for one key stroke
            if (!this._innerTextBuffer || this._innerTextBuffer !== innerText) {
                console.log(innerText); // Call this.setState or this.props.onChange here
                this._innerTextBuffer = innerText;
            }
        });

blocks|key|4642379|text|这是对我有效的最简单的解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4642380|<div

++onInput={e+=>+console.log('Text+inside+div',+e.currentTarget.textContent)}

<p>This is the is simplest solution that worked for me.</p>

<pre><code>&lt;div
  contentEditable='true'
  onInput={e =&gt; console.log('Text inside div', e.currentTarget.textContent)}
&gt;
Text inside div
&lt;/div&gt;
</code></pre>


blocks|key|135673|text|因为当编辑完成时，元素的焦点总是丢失的，您可以简单地使用onBlur钩子。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|135674|<div+onBlur={(e)=>{console.log(e.currentTarget.textContent)}}+contentEditable+suppressContentEditableWarning={true}>

<p>Since when the edit is complete the focus from the element is always lost you could simply use the onBlur hook.</p>

<pre><code>&lt;div onBlur={(e)=&gt;{console.log(e.currentTarget.textContent)}} contentEditable suppressContentEditableWarning={true}&gt;
     &lt;p&gt;Lorem ipsum dolor.&lt;/p&gt;
&lt;/div&gt;
</code></pre>

<p>if you are looking for an easy and simple way here it is.</p>
<pre><code>&lt;div

    onChange={() =&gt; callMeOnChange()}
    onMouseUp={() =&gt; callMeOnMouseUp()}
    className=&quot;myClassNameHere&quot;/&gt;

<p>if you want to get the selected text when the selection is triggered you can do this.</p>
<pre><code>let selection = window.getSelection().toString();

<p>I've tried to use the <a href="https://stackoverflow.com/a/57365612/6243352">example from Saint Laurent</a> above:</p>
<pre class="lang-html prettyprint-override"><code>&lt;div

  suppressContentEditableWarning={true}
&gt;
  &lt;p&gt;Lorem ipsum dolor.&lt;/p&gt;
&lt;/div&gt;
</code></pre>
<p>It's working perfectly until I've tried to set this value in state. When I'm using a functional component that calls <code>setState(e.currentTarget.textContent)</code>, I'm getting <code>currentTarget</code> as null. <code>setState</code> works asynchronously and <code>currentTarget</code> is not available there.</p>
<p>The fix that worked for me in React 17.0.2 was to use <code>e.target.innerText</code>:</p>
<pre class="lang-html prettyprint-override"><code>&lt;div
  onBlur={e =&gt; setState(e.target.innerText)}
  contentEditable
  suppressContentEditableWarning={true}
&gt;
