react打包脚本和example, 这里的版本请忽略

import {PureComponent} from 'react';
import PropTypes from 'prop-types';

/**
 * 文档标题
 */
export default class DocumentTitle extends PureComponent {
    static propTypes = {
        title: PropTypes.string
    };

    static defaultProps = {
        title: ''
    };

    componentDidMount() {
        this.setTitle(this.props.title);
    }

    componentWillReceiveProps(nextProps) {
        if (nextProps.title && nextProps.title !== this.props.title) {
            this.setTitle(nextProps.title);
        }
    }

    /**
     * 设置文档标题
     */
    setTitle = title => {
        window.document.title = title;
    };

    render() {
        return null;
    }
}
