# --description--
|
|
|
|
Dato che le sfide continuano a utilizzare composizioni più complesse di componenti React e JSX, c'è un punto importante da osservare. Il rendering di componenti di classe stile ES6 all'interno di altri componenti non è diverso dal render dei componenti semplici che hai usato nelle ultime sfide. All'interno di altri componenti puoi fare il render di elementi JSX, componenti funzionali senza stato, e componenti di classe ES6.
|
|
|
|
# --instructions--
|
|
|
|
Nell'editor di codice, il componente `TypesOfFood` sta già mostrando un componente chiamato `Vegetables`. Inoltre, c'è il componente `Fruits` preso dall'ultima sfida.
|
|
|
|
Annida due componenti all'interno di `Fruits` — prima `NonCitrus`, e poi `Citrus`. Entrambi questi componenti ti sono forniti dietro le quinte. Successivamente, annida il componente di classe `Fruits` nel componente `TypesOfFood`, sotto l'intestazione `h1` e sopra `Vegetables`. Il risultato dovrebbe essere una serie di componenti annidati, che utilizza due tipi di componenti diversi.
|
|
|
|
# --hints--
|
|
|
|
Il componente `TypesOfFood` dovrebbe restituire un singolo elemento `div`.
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
const mockedComponent = Enzyme.mount(React.createElement(TypesOfFood));
|
|
return mockedComponent.children().type() === 'div';
|
|
})()
|
|
);
|
|
```
|
|
|
|
Il componente `TypesOfFood` dovrebbe restituire il componente `Fruits`.
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
const mockedComponent = Enzyme.mount(React.createElement(TypesOfFood));
|
|
return mockedComponent.children().childAt(1).name() === 'Fruits';
|
|
})()
|
|
);
|
|
```
|
|
|
|
Il componente `Fruits` dovrebbe restituire il componente `NonCitrus` e il componente `Citrus`.
|
|
|
|
```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
|
|
);
|
|
})()
|
|
);
|
|
```
|
|
|
|
Il componente `TypesOfFood` dovrebbe restituire il componente `Vegetables` sotto il componente `Fruits`.
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
const mockedComponent = Enzyme.mount(React.createElement(TypesOfFood));
|
|
return mockedComponent.children().childAt(2).name() === 'Vegetables';
|
|
})()
|
|
);
|
|
```
