AAAAAAAAAAAAAAA * fix: separate the test Okay apparently the test does not work unless we separate it into a different `it` statement. >:( >:( >:( >:( Co-authored-by: Sujal Gupta <55016909+heysujal@users.noreply.github.com> Co-authored-by: Noor Fakhry <65724923+NoorFakhry@users.noreply.github.com> Co-authored-by: Oliver Eyton-Williams <ojeytonwilliams@gmail.com> Co-authored-by: Nicholas Carrigan (he/him) <nhcarrigan@gmail.com>

--description--
你已經瞭解了 JSX 和 React 組件的基礎知識,是時候自己編寫一個組件了。 React 組件是 React 應用程序的核心組成部分,因此熟練編寫它們是非常重要的。 記住,典型的 React 組件是 ES6 class
,它擴展了 React.Component
。 它有一個返回 HTML(從 JSX 返回)或 null
的渲染方法, 這是 React 組件的基本形式。 理解了這一點之後,就可以開始構建更復雜的 React 項目了。
--instructions--
定義一個 MyComponent
類,它是 React.Component
的擴展。 它的渲染方法應該返回一個 div
,其中包含一個 h1
標籤,標籤文本爲:My First React Component!
。 準確使用此文本,大小寫和標點符號也要考慮。 確保也調用組件的構造器。
使用 ReactDOM.render()
把該組件渲染到 DOM 中。 有一個 id='challenge-node'
的 div
可供渲染。
--hints--
應該有一個名爲 MyComponent
的 React 組件。
(getUserInput) =>
assert(
__helpers
.removeWhiteSpace(getUserInput('index'))
.includes('classMyComponentextendsReact.Component{')
);
MyComponent
應該包含一個 h1
標籤,標籤的文本爲 My First React Component!
,區分大小寫並有標點符號。
assert(
(function () {
const mockedComponent = Enzyme.mount(React.createElement(MyComponent));
return mockedComponent.find('h1').text() === 'My First React Component!';
})()
);
MyComponent
應該渲染到 DOM。
assert(document.getElementById('challenge-node').childNodes.length === 1);
MyComponent
應該有一個構造器,裏面調用了傳參 props
的 super
函數。
assert(
MyComponent.toString().includes('MyComponent(props)') &&
MyComponent.toString().includes('_super.call(this, props)')
);

// Change code below this line
class MyComponent extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
<h1>My First React Component!</h1>
</div>
);
}
};
ReactDOM.render(<MyComponent />, document.getElementById('challenge-node'));
