推荐答案
根据您使用的React版本，您希望将该组件包装在React.renderToString，React.renderComponent或ReactDOMServer.renderToString调用中.当然，这也意味着您需要确保React/ReactDOMServer在弹出窗口生成器的范围内.另请参见此答案.
Depending on the version of React you're using, you want to wrap that component in a React.renderToString, React.renderComponent, or a ReactDOMServer.renderToString call. Of course, this also means that you need to make sure React/ReactDOMServer is within the scope of the popup window generator. See also this answer.
var ReactDOMServer = require('react-dom/server');
// ...
ReactDOMServer.renderToString(<Barcode
value="Rakesh"// {this.state.value}
width="2"
height="100"
format="CODE128"
displayValue=""
fontOptions=""
font="monospace"
textAlign="center"
textPosition="bottom"
textMargin="2"
fontSize="20"
background="#ffffff"
lineColor="#000000"
margin="10"
marginTop=""
marginBottom=""
marginLeft=""
marginRight=""
/>
