如何从 React ContentEditable 提取没有 HTML 实体编码的文本？

Question

I have this textArea based on react react-contenteditable. When a user writes something

for example "A & B", the e.target.value; in onChange event handler return it as "A & amp; B". How can I extract it the same as the original text?

onChange(e) {
    const val = e.target.value;

    this.setState({
        value: val
    });
    return this.props.onChange(e, this.props.value, val);
}

onPaste(e) {
    e.preventDefault();
    const text = e.clipboardData.getData("text/plain");

    document.execCommand("insertText", false, text);
    return true;
}

render() {
    return (
        <ContentEditable
            className={this.state.className}
            html={this.state.value}
            placeholder={this.props.placeholder}
            disabled={false}
            onPaste={this.onPaste}
            onBlur={::this.onBlur}
            onFocus={::this.onFocus}
            onChange={::this.onChange}
        />
    );
}

This package is meant to handle HTML (for rich text) thus the value returned is HTML. But if you want the parsed text (which will lack the rich text) you can directly read the text from the contenteditable div.

The package provides a nice interface to forward a ref to the contenteditable div with the prop innerRef . You can then access the parsed text any time with innerRef.current.innerText .

constructor() {
    this.editableRef = React.createRef(null);
}

onChange(e) {
    console.log(this.editableRef.current.innerText);

    const val = e.target.value;
    this.setState({ value: val });
    return this.props.onChange(e, this.props.value, val);
}


render() {
    return (
        <ContentEditable
            innerRef={this.editableRef}
            html={this.state.value}
            onChange={::this.onChange}
        />
    );
}
