Redux表格打字稿通过自定义道具-Java 学习之路

我正在尝试将自定义道具传递给我用 reduxForm 装饰的组件 . 我也是新手稿 .

第一个问题是我不能用connect连接装饰组件：

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'.

它需要将任何道具传递给 validate 表单函数，但它对将来的任务非常有帮助 .

主要问题是我无法将自定义道具传递给装饰组件：

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

表格道具：

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

当我尝试这个：

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

它引发了另一个错误：

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 InjectedFormProps 界面中声明的道具，但我无法传递任何自定义道具 . 实际上，我能够从 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 .

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

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 />

这里有一个如何定义自定义道具的示例：

import { FormProps, reduxForm } from "redux-form";

interface InitialValuesProps {
  name: string;
}

interface CustomFormProps extends FormProps<InitialValuesProps, {}, {}> {
  loading: boolean;
}

class CustomForm extends React.Component<CustomFormProps> {
   render() {
      const loading = this.props.loading 
      const name = this.props.initialValues.name;
   }
}

export default reduxForm({ form: 'myForm' })(CustomForm)
