我是React的新手,我在显示动态unicode值时遇到一些问题?

{'\u{1F680}'} become {'\u{MyVar}'}

答案 0 :(得分:1)

String.fromCodePoint将使您从数字代码点获得字符,而parseInt将使您从十六进制字符串获得数字。

您的转换将如下所示:String.fromCodePoint(parseInt(MyVariable, 16))

工作示例:

const App = ({ unicode }) => <p> 3, 2, 1, GO ! {String.fromCodePoint(parseInt(unicode, 16))}</p>

ReactDOM.render(<App unicode='1F680'/>, document.getElementById('root'))
