道具验证中缺少React eslint错误

时间:2016-07-31 14:19:33

标签: javascript reactjs eslint flowtype

我有下一个代码,eslint throw:

  

react / prop-types onClickOut;道具验证中缺少

     

反应/支持儿童;道具验证中缺少

propTypes已定义,但eslint无法识别它。

import React, { Component, PropTypes } from 'react';

class IxClickOut extends Component {
  static propTypes = {
    children: PropTypes.any,
    onClickOut: PropTypes.func,
  };

 componentDidMount() {
    document.getElementById('app')
      .addEventListener('click', this.handleClick);
  }

  componentWillUnmount() {
    document.getElementById('app')
      .removeEventListener('click', this.handleClick);
  }

  handleClick = ({ target }: { target: EventTarget }) => {
    if (!this.containerRef.contains(target)) {
      this.props.onClickOut();
    }
  };

  containerRef: HTMLElement;

  render() {
    const { children, ...rest } = this.props;
    const filteredProps = _.omit(rest, 'onClickOut');

    return (
      <div
        {...filteredProps}
        ref={container => {
          this.containerRef = container;
        }}
      >
        {children}
      </div>
    );
  }
}

export default IxClickOut;

如果你想在类声明中使用它,你需要将propTypes定义为静态getter:

static get propTypes() { 
    return { 
        children: PropTypes.any, 
        onClickOut: PropTypes.func 
    }; 
}

如果要将其定义为对象,则需要在类外定义它,如下所示:

IxClickOut.propTypes = {
    children: PropTypes.any,
    onClickOut: PropTypes.func,
};

此外,如果您从prop-types而不是 react导入道具类型会更好,否则您会在控制台中看到警告(作为React 16的准备工作) :

import PropTypes from 'prop-types';

似乎问题出在eslint-plugin-react

如果你通过在课堂的任何地方进行解构来注释命名对象,则无法正确检测propTypes中提到的道具。

过去有similar problem

答案 2 :(得分:3)

我知道这个答案很荒谬,但是请考虑禁用此规则,直到发现错误或升级工具为止。

/* eslint-disable react/prop-types */ // TODO: upgrade to latest craco+eslint or Next.js?

问题是在handleClick中的流注释,我删除了这个并且工作正常 谢谢@alik

答案 4 :(得分:2)

问题:道具验证(eslintreact / prop-types)中缺少“ id1”

<div id={props.id1} >
    ...
</div>

以下解决方案在功能组件中起作用:

let { id1 } = props;

<div id={id1} >
    ...
</div>

希望有帮助。

PropTypes 检查是个好东西,不建议设置忽略

您可以使用 vscode React PropTypes Generate 扩展自动生成 propTypes:

  1. 选择组件的名称
  2. 按命令 + 。 (Windows 是 Ctrl + 。)显示代码操作并选择 PropTypesGenerate,或在 macOS 中按 shift + command + alt + P(Windows 是 shift + ctrl + alt + P)
  3. 输入 propType 替换默认类型

答案 6 :(得分:0)

过去几天,我遇到了这个问题。就像Omri Aharon在上面的回答中说的那样,为您的道具类型添加类似于以下内容的定义很重要:

SomeClass.propTypes = {
    someProp: PropTypes.number,
    onTap: PropTypes.func,
};

别忘了在类外添加prop定义。我会将其放在班级的下方/上方。如果不确定PropType的变量类型或后缀是什么(例如:PropTypes.number),请参阅此npm reference。要使用PropType,必须导入包:

import PropTypes from 'prop-types';

如果出现linting错误:someProp is not required, but has no corresponding defaultProps declaration,您要做的就是将.isRequired添加到prop定义的末尾,如下所示:

SomeClass.propTypes = {
    someProp: PropTypes.number.isRequired,
    onTap: PropTypes.func.isRequired,
};

或添加默认的prop值,例如:

SomeClass.defaultProps = {
    someProp: 1
};

如果您像我一样,没有经验或不熟悉reactjs,您可能还会收到以下错误:Must use destructuring props assignment。要解决此错误,请在使用道具之前先定义它们。例如:

const { someProp } = this.props;

对我来说,将 eslint-plugin-react 升级到最新版本7.21.5可以解决此问题

答案 8 :(得分:0)

函数式 React 组件。定义为对象。我收到此错误是因为我从另一个名称略有不同的对象复制并粘贴了该对象,而忘记更改 proptypes 对象的名称。

FooterIcons.propTypes = {} -> FooterIcon.propTypes

我发现 eslint 在我自己工作的项目中过于严格,但对于这个错误,我通过定义我的接口然后实现它来修复它:

interface myInterface: {
  test: string
}

const MyComponent: React.FC<myInterface> = (props: myInterface) => {
