# --description--
|
||
|
||
隨着挑戰繼續,將組合使用更復雜的 React 組件和 JSX,有一點需要注意。 在其它組件中渲染 ES6 風格的類組件和渲染在過去幾個挑戰中使用的簡單組件沒有什麼不同。 可以在其它組件中渲染 JSX 元素、無狀態功能組件和 ES6 類組件。
|
||
|
||
# --instructions--
|
||
|
||
在代碼編輯器中,`TypesOfFood` 組件已經渲染了一個名爲 `Vegetables` 的組件。 此外,還有上次挑戰中的 `Fruits` 組件。
|
||
|
||
在 `Fruits` 中嵌套兩個組件,首先 `NonCitrus`,然後是 `Citrus`, 這兩個組件都已經引入。 接下來,將 `Fruits` 類組件嵌到 `TypesOfFood` 組件中,位於 `h1` 標題下方和 `Vegetables` 上方。 結果應該是一系列嵌套的組件,它們使用兩種不同的組件類型。
|
||
|
||
# --hints--
|
||
|
||
`TypesOfFood` 組件應該返回單個 `div` 元素。
|
||
|
||
```js
|
||
assert(
|
||
(function () {
|
||
const mockedComponent = Enzyme.mount(React.createElement(TypesOfFood));
|
||
return mockedComponent.children().type() === 'div';
|
||
})()
|
||
);
|
||
```
|
||
|
||
`TypesOfFood` 組件應該返回 `Fruits` 組件。
|
||
|
||
```js
|
||
assert(
|
||
(function () {
|
||
const mockedComponent = Enzyme.mount(React.createElement(TypesOfFood));
|
||
return mockedComponent.children().childAt(1).name() === 'Fruits';
|
||
})()
|
||
);
|
||
```
|
||
|
||
`Fruits` 組件應該返回 `NonCitrus` 組件和 `Citrus` 組件。
|
||
|
||
```js
|
||
assert(
|
||
(function () {
|
||
const mockedComponent = Enzyme.mount(React.createElement(TypesOfFood));
|
||
return (
|
||
mockedComponent.find('Fruits').children().find('NonCitrus').length ===
|
||
1 &&
|
||
mockedComponent.find('Fruits').children().find('Citrus').length === 1
|
||
);
|
||
})()
|
||
);
|
||
```
|
||
|
||
`TypesOfFood` 組件應該返回 `Vegetables` 組件,且其位於 `Fruits` 組件之下。
|
||
|
||
```js
|
||
assert(
|
||
(function () {
|
||
const mockedComponent = Enzyme.mount(React.createElement(TypesOfFood));
|
||
return mockedComponent.children().childAt(2).name() === 'Vegetables';
|
||
})()
|
||
);
|
||
```
