我已经定义了两个这样的React组件:
class CmpA extends React.Component
{ ... }
class CmpB extends React.Component
{ ... }
如您所见,它们是在ES6语法中定义的。我使用Webpack和Babel将它们转换为ES5。我想要做的是将组件定义存储在变量中,然后呈现它:
render() {
let Cmp = Math.random() > 0.5 ? CmpA : CmpB;
return <Cmp />;
}
但由于上述代码转换为:
,因此无效render() {
var Cmp = Math.random() > 0.5 ? CmpA : CmpB;
return _react2.default.createElement('Cmp', {});
}
有谁知道如何克服这个问题?
[UPDATE]
还请考虑我需要像这样使用Cmp
:
render() {
let Cmp = Math.random() > 0.5 ? CmpA : CmpB;
return <div><Cmp /></div>;
}
或者换句话说,我需要能够动态命名一个组件!

这是我的项目的package.json文件的内容:

我相信你可以这样做:
render() {
const props = { prop1: 10 };
let Cmp = Math.random() > 0.5 ? <CmpA {...props} /> : <CmpB {...props} />;
return <div>{Cmp}</div>;
}
