收到以下错误:
Error TS2345 Argument of type 'typeof SomeComponent'
is not assignable to parameter of type 'ReactElement<{}>'.
Property 'type' is missing in type 'typeof SomeComponent'.
获得以下代码打字稿代码:
import * as React from 'react';
import * as ReactDOM from 'react-dom';
interface IProps{}
interface IState {}
class SomeComponent extends React.Component<IProps, IState> {
render() {
return <div />;
}
}
var component = SomeComponent;
var root = document.getElementById("root");
ReactDOM.render(component , root);
我尝试了以下内容:
class SomeComponent extends React.Component<IProps, IState> {
render() {
return <div />;
}
get type() {
return "test";
}
}
答案 0 :(得分:4)
应该是这样的:
interface IProps{}
interface IState {}
class SomeComponent extends React.Component<IProps, IState> {
render() {
return <div />;
}
}
ReactDOM.render(<SomeComponent /> , document.getElementById("root"));
您没有将组件类传递给render
函数,您需要传递实例。
此:
var component = SomeComponent;
将类SomeComponent
的引用分配到component
变量中,这意味着如果您这样做,那么您可以同时执行这两项操作,它们是相同的:
var componentInstance1 = <SomeComponent />
var componentInstance2 = <component />
如果你不想使用jsx / tsx表示法,那么在构建组件时你需要传递道具:
var component = new SomeComponent(props);
