Fit parent height for Table in Material UI?

由 时光毁灭记忆、已成空白 提交于 2021-02-18 19:31:04
问题 I want the table height to fit the parent’s available height. Ideally, I want: The footer to always be docked at the bottom of the parent container. If the table contains a few rows, the footer should remain docked at the bottom. If the table contains more rows than fit the parent’s height and needs to overflow then the overflow should be visible only for the table body, and the footer should remain docked at the bottom and not be pushed downwards. A flexbox approach if possible (it seems to

如何在react中处理onKeyPress事件

由 孤人 提交于 2021-02-18 15:55:10
参考： https://stackoverflow.com/questions/27827234/how-to-handle-the-onkeypress-event-in-reactjs 以前过时的做法：使用keyCode var Test = React.createClass({ add: function(event){ if(event.keyCode == 13){ alert('Adding....'); } }, render: function(){ return( <div> <input type="text" id="one" onKeyPress={this.add} /> </div> ); } }); React.render(<Test />, document.body); 现在建议的做法：使用语义化的key handleKeyPress = (event) => { if(event.key === 'Enter'){ console.log('enter press here! ') } } render: function(){ return( <div> <input type="text" id="one" onKeyPress={this.handleKeyPress} /> </div> ); } 来源： oschina 链接：

How to add Adsense to a website built with GatsbyJS?

由 梦想的初衷 提交于 2021-02-17 08:47:19
问题 I'd like to know where I should add the <script></script> provided by Google Adsense. They say to add it into the <head></head> , but in Gatsby you have Helmet as <head> . I tried also to add the script inside an html.js file where it's located a <head> tag with {``} to escape the <script> tag, but it outputs at the top of the website the script content. TL;DR: What is the optimal way to add Adsense to a website built with GatsbyJS? I've tried to use the react adsense package but I do not

JSX can be used without importing React

由 ﹥＞﹥吖頭↗ 提交于 2021-02-16 18:23:34
问题 I'm trying to run my first React JSX file with create-react-app with version 4.0.0 and it works! However, I don't have the import statements of React included in my JSX and it works too but it is very weird. The project is created by create-react-app command with version 4.0.0. The App.js file: /* without import React but works too! */ import { Component } from "react"; class App extends Component { render() { return <div>456</div>; } } export default App; 回答1: This is new with the JSX

Dynamic JSX element/tag names

由 时间秒杀一切 提交于 2021-02-16 13:39:10
问题 I'm just wanted to know if there is a best practice approach to rendering an element with ReactJS dynamically Consider these scenarios: (1) Parameter Factory component: A parameterised factory component whose job is to render a component based on a string parameter , is there a way of doing so without having to revert to React.createElement? <pre><code>// The following doesn't work class Quiz extends React.Component{ constructor (props){ super (props); this.state = { questionText: '',

Problem with Visual Studio Code using “react-jsx” as jsx value with create-react-app

由 不羁岁月 提交于 2021-02-15 12:07:13
问题 I'm struggling with following "error" in VSCode : Argument for '--jsx' option must be: 'preserve', 'react-native', 'react' Hence, react-scripts (create-react-app) automatically sets the jsx key to react-jsx value, when react value seems to work. Actually, the code works perfectly and displays the page I want, but the IDE is underlining kinda everything as errors, saying : Cannot use JSX unless the '--jsx' flag is provided. Here is my tsconfig.json : { "compilerOptions": { "target": "es5",

EsLint入门

EsLint入门 介绍 官方地址：http://eslint.org/ EsLint帮助我们检查Javascript编程时的语法错误。比如：在Javascript应用中，你很难找到你漏泄的变量或者方法。EsLint能够帮助我们分析JS代码，找到bug并确保一定程度的JS语法书写的正确性。 EsLint是建立在Esprima(ECMAScript解析架构)的基础上的。Esprima支持ES5.1,本身也是用ECMAScript编写的，用于多用途分析。EsLint不但提供一些默认的规则（可扩展），也提供用户自定义规则来约束我们写的Javascript代码。 EsLint提供以下支持： ES6 AngularJS JSX Style检查 自定义错误和提示 EsLint提供以下几种校验： 语法错误校验 不重要或丢失的标点符号，如分号 没法运行到的代码块（使用过WebStorm的童鞋应该了解） 未被使用的参数提醒 漏掉的结束符，如} 确保样式的统一规则，如sass或者less 检查变量的命名 使用 一、安装 Npm install gulp-eslint –save-dev 在你的项目目录下，运行：eslint –init将会产生一个.eslintrc的文件，文件内容包含一些校验规则 { "rules": { "semi": ["error", "always"], "quotes": [
