问题描述
I've created a react application following the steps on the React Website, but I'm having issues utilizing the React-Select Library (particularly the Select Component).
我只能使用CDN文件加载依赖项，包括位于 cdnjs
I can only use cdn files to load dependencies, including the React-Select cdn file located on cdnjs
https://cdnjs.cloudflare.com/ajax/libs/react-select/2.1.2/react-select.js
我的react-app出现以下错误:
I'm getting the following error with my react-app:
ReferenceError: Select is not defined[Learn More]
请参见下面的脚本，并在此处为我的codepen

];
class App extends React.Component {
state = {
selectedOption: null,
}
handleChange = (selectedOption) => {
this.setState({ selectedOption });
console.log(`Option selected:`, selectedOption);
}
render() {
const { selectedOption } = this.state;
return (
<div>
Test Text
<Select
value={selectedOption}
onChange={this.handleChange}
options={options}
/>
</div>
);
}
}
ReactDOM.render(<App/>, document.querySelector("#root"))
</script>
