【问题描述】：

我是 js 新手。 修复了其他无法仅修复 props lint 错误的 lint 错误

我收到以下 lint 错误，用 Google 搜索该错误无法弄清楚问题所在。 17:20 错误“playerLaughing”在道具验证反应/道具类型中丢失

提供以下代码

你们能告诉我如何解决它吗

import React from 'react';


class Swimming extends React.Component 
    constructor(props) 
        super(props);
        this.playerLaughing = this.playerLaughing.bind(this);
    

    playerLaughing() 
          //console.log("playerLaughing");
         // debugger;
        this.props.playerLaughing(this.props.id);
    

    render() 
          //console.log("render");
          //console.log("accordion / the ExpandCollapse Section component");
        var className = 'player-section' + (this.props.jumping ? ' jumping' : '');

        return (
            <div className=className onClick=this.playerLaughing>

                <div className = "sports-player-question-flying sports-submenu-dropmenuHeader">
                    <h3>
                        this.props.flying
                    </h3>

                    <div className="up-arrow"></div>
                </div>

                <div className="body">
                    this.props.children
                </div>


            </div>
        );

  




export default Swimming;

【参考方案1】：

您需要在组件上设置静态属性“propTypes”以满足此 lint 错误。

这里有一些关于 React 的 PropTypes 的信息：React Docs

您将添加一个类似于此的部分：

import React from 'react';
import PropTypes from 'prop-types';

class Swimming extends React.Component 
 static propTypes = 
   jumping: PropTypes.bool,
   playerLaughing: PropTypes.func
 ;
 constructor(props) 
 ...

您需要安装“prop-types”npm 包。

【讨论】：

嘿，我添加了以下行，但出现此错误 Uncaught ReferenceError: PropTypes is not defined 你能告诉我如何解决它 Uncaught ReferenceError: PropTypes is not defined render() const playerLaughing , 跳跃 = this.props; SectionExpandCollapse.propTypes = playerLaughing: PropTypes.func, jumping: PropTypes.bool ;

你需要从 npm 安装并导入 PropTypes 包。在您的控制台中输入npm install -S prop-types，然后在您导入反应类型import PropTypes from 'prop-types'的正下方@

【参考方案2】：

您应该将propTypes 添加到您的组件中： 例如：

// this goes outside the class deceleration 
Swimming.propTypes = 
    playerLaughing: PropTypes.func,
    jumping: PropTypes.bool,
    //... other props you will use in this component
;  

如果你想在 class 减速中使用它，你可以像这样使用静态类字段：

// this goes inside the class deceleration
static propTypes = 
        playerLaughing: PropTypes.func,
        jumping: PropTypes.bool,
        //... other props you will use in this component
    ;
; 

您应该安装并导入PropTypes。见Docs

npm install --save prop-types
import PropTypes from 'prop-types'; // ES6 
var PropTypes = require('prop-types'); // ES5 with npm
