reactjs - 将函数传递给包装的组件 Prop 时发出警告

Question

目前我有一个 ValidatedTextField 组件，它包装了一个 TextField 组件，并接受了一个 validationerror 属性，该属性用于在子进程之间进行通信和父级，并由文本框的 onChange 或 onBlur 事件使用。

然而，当将一个函数传递给这个属性时，我收到以下错误:

Invalid value for prop validationerror on tag. Either remove it from the element, or pass a string or number value to keep it in the DOM. For details, see https://reactjs.org/blog/2017/09/08/dom-attributes-in-react-16.html#changes-in-detail

我已经阅读了链接，上面说数据和 aria 属性仍然可以自由传递，但是切换到使用数据属性会导致同样的错误。我想不出还有什么方法可以发送函数来更新父错误。

来自包装器

<ValidatedTextField
    type="text"
    variant="standard"
    required={true}
    validateon={'onChange'}
    validate={[Validations.Required, Validations.allowedNameCharacters]}
    validationerror={(validationError: boolean) => this.setState({ HasError: validationError }) }
    onChange={(event: any) => this.setState({ textboxvalue: event.target.value })}
    value={this.state.textboxvalue}
/>

和包装组件

import * as React from 'react';
import * as _ from 'lodash'
import { IValidationItem } from '../../../Interfaces/IValidationItem'
import TextField, { TextFieldProps } from "@material-ui/core/TextField";

interface IValidatedTextFieldProps {
    validate?: IValidationItem[],
    validateon?: 'onBlur' | 'onChange',
    validationerror?: (hasError?: boolean) => void
}

interface IValidatedTextFieldState {
    validationErrorMessage: string,
    validationError: boolean
}


type ValidatedTextFieldAllProps = IValidatedTextFieldProps & TextFieldProps

class ValidatedTextField extends React.Component<ValidatedTextFieldAllProps, IValidatedTextFieldState> {

    public constructor(props: ValidatedTextFieldAllProps) {
        super(props);
        this.state = {
            validationErrorMessage: "",
            validationError: false
        }
    }
    public validationWrapper = (event: any) => {

        const { validate, } = this.props;
        return !validate ? "" : _.forEach(validate, (validationItem: IValidationItem) => {
            const result = !validationItem.func(event.target.value)

            if (result) {
                this.setState({ validationErrorMessage: validationItem.validationMessage });
                this.setState({ validationError: result })
                this.callParentValidationErrorMethod(result)
                return false;
            }
            else {
                this.setState({ validationErrorMessage: "" });
                this.setState({ validationError: result })
                this.callParentValidationErrorMethod(result)
                return;
            }
        });
    };

    public onBlurValidation = (event: any) => {
        const { onBlur, validateon, validate } = this.props;
        if (_.isFunction(onBlur)) { onBlur(event); }
        if (validateon === "onBlur" && !!validate) { this.validationWrapper(event); 
    }

    public onChangeValidation = (event: any) => {
        const { onChange, validateon, validate } = this.props;
        if (_.isFunction(onChange)) { onChange(event); }
        if (validateon === "onChange" && !!validate) { this.validationWrapper(event); };
    }
    public callParentValidationErrorMethod = (hasError: boolean) => {
        if(_.isFunction(this.props.validationerror)) {
            this.props.validationerror(hasError);
        }
    }

    public render() {
        const { validationErrorMessage, validationError } = this.state


        return (<TextField
            {...this.props}
            onBlur={(event: any) => { this.onBlurValidation(event); }}
            onChange={(event: any) => { this.onChangeValidation(event); }
            }
            error={validationError}
            helperText={validationErrorMessage}
        />)
    }
}

export default ValidatedTextField;

附加信息:目前在 IE 中仅 chrome 和当前 React v16.6 中未见

好的解决了

问题是我在组件的文本字段上传播所有属性，包括文本字段上不存在的属性。外推我不需要的属性并仅绑定(bind)默认文本字段属性解决了这个问题

const {validationerror,validate,validateon, ...textFieldProps   } = this.props;
       return (<TextField
           {...textFieldProps}
           onBlur={(event: any) => { this.onBlurValidation(event); }}
           onChange={(event: any) => { this.onChangeValidation(event); }
           }
           error={validationError}
           helperText={validationErrorMessage}
       />)
