Redux 表单 Typescript 传递自定义道具 [英] Redux Form Typescript Pass Custom Props

问题描述

我正在尝试将自定义道具传递给我用 reduxForm 装饰的组件.另外我对打字稿很陌生.

I am trying to pass custom props to my component which is decorated with reduxForm. Also I am very new in Typescript.

第一个问题是我不能用connect包装装饰的组件:

The first problem is that I can't wrap the decorated component with connect:

export default
    connect(mapStateToProps)(
        reduxForm({
            form: 'myform'
        })(MyComponent)
    )

错误:

Error:(89, 5) TS2345:Argument of type 'DecoratedComponentClass<any, Partial<ConfigProps<any, {}>>>' is not assignable to parameter of type 'ComponentType<{ addressValue: any; isDeliveryAddress: any; customerTypeValue: any; } & DispatchPr...'.
Type 'DecoratedComponentClass<any, Partial<ConfigProps<any, {}>>>' is not assignable to type 'StatelessComponent<{ addressValue: any; isDeliveryAddress: any; customerTypeValue: any; } & Dispa...'.
Type 'DecoratedComponentClass<any, Partial<ConfigProps<any, {}>>>' provides no match for the signature '(props: { addressValue: any; isDeliveryAddress: any; customerTypeValue: any; } & DispatchProp<any> & { children?: ReactNode; }, context?: any): ReactElement<any> | null'.

这显然是由错误的类型引起的，但正如我所说，我是 Typescript 的新手，我不确定如何处理这些长错误.目前我不需要将任何道具传递给 validate 表单函数，但这对未来的任务非常有帮助.

It's obviously caused by wrong types but as I said I am new in Typescript and I am not sure how to deal with these long errors. At this moment I don't need to pass any props to the validate form function but it will be very helpful for future tasks.

主要问题是我无法将自定义道具传递给装饰组件:

The main problem is that I can't pass custom props to the decorated component:

export default reduxForm({
    form: 'myform'
})(
    connect(mapStateToProps)(MyComponent)
);

表单道具:

interface Props extends InjectedFormProps {
    onSubmit: () => void;
    // some values from the state
    loading: boolean; // the custom prop
}

当我尝试这个时:

<MyForm loading onSubmit={this.handleSubmit} />

它抛出另一个错误:

Error:(134, 25) TS2339:Property 'loading' does not exist on type 'IntrinsicAttributes & IntrinsicClassAttributes<FormInstance<any, Partial<ConfigProps<any, {}>>>> ...'.

奇怪的是，我能够传递在 InjectedFormProps 接口中声明的道具，但我无法传递任何自定义道具.实际上，我可以从 mapStateToProps 函数传递任何道具.也许我只是无法使用 reduxForm 将任何自定义道具传递给装饰组件.

The strange part is that I am able to pass props that are declared in the InjectedFormProps interface but I can't pass any custom props. Actually, I am able to pass any props from the mapStateToProps function. Maybe I just can't pass any custom props to the decorated component with reduxForm.

推荐答案

@types/redux-form 7.0.10 和 redux-form 7.1.2 的工作解决方案:

Working solution for @types/redux-form 7.0.10 and redux-form 7.1.2:

在MyForm.tsx中定义表单组件:

import * as React from "react";
import { InjectedFormProps, reduxForm } from 'redux-form';
import { connect } from 'react-redux';

interface StateProps {
  valueFromState: string;
}

interface Props extends StateProps {
    loading: boolean; // the custom prop
}

const MyForm: React.StatelessComponent<Props & InjectedFormProps<{}, Props>> =
  ({handleSubmit, loading}) => (
    <form onSubmit={handleSubmit}>
      {loading && (<p>loading...</p>)}
    </form>
)

const mapStateToProps = (state: any): StateProps => ({valueFromState: "1"});

export default connect(mapStateToProps)(
  reduxForm<{}, Props>({
    form: 'myform'
  })(MyForm)
);

然后使用它:

import MyForm from './MyForm';
<MyForm onSubmit={() => console.log("submit")} loading />
