# --description--
|
|
|
|
Le ultime sfide hanno mostrato i modi fondamentali per passare le proprietà ai componenti figli. Ma cosa succede se il componente figlio a cui stai passando una prop è un componente di classe ES6, piuttosto che un componente funzionale senza stato? Il componente di classe ES6 utilizza una convenzione leggermente diversa per accedere alle proprietà.
|
|
|
|
Ogni volta che fai riferimento a un componente di classe all'interno di sé stesso, usa la parola chiave `this`. Per accedere alle proprietà all'interno di un componente di classe, premetti `this` al codice che usi per accedervi. Ad esempio, se un componente di classe ES6 ha una prop chiamata `data`, scriverai `{this.props.data}` in JSX.
|
|
|
|
# --instructions--
|
|
|
|
Mostra un'istanza del componente `ReturnTempPassword` nel componente genitore `ResetPassword`. Qui, dai a `ReturnTempPassword` una prop di `tempPassword` e assegnale un valore stringa di almeno 8 caratteri. All'interno del figlio, `ReturnTempPassword`, accedi alla prop `tempPassword` all'interno dei tag `strong` per assicurarti che l'utente veda la password temporanea.
|
|
|
|
# --hints--
|
|
|
|
Il componente `ResetPassword` dovrebbe restituire un singolo elemento `div`.
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
|
|
return mockedComponent.children().type() === 'div';
|
|
})()
|
|
);
|
|
```
|
|
|
|
Il quarto figlio di `ResetPassword` dovrebbe essere il componente `ReturnTempPassword`.
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
|
|
return (
|
|
mockedComponent.children().childAt(3).name() === 'ReturnTempPassword'
|
|
);
|
|
})()
|
|
);
|
|
```
|
|
|
|
Il componente `ReturnTempPassword` dovrebbe avere una prop chiamata `tempPassword`.
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
|
|
return mockedComponent.find('ReturnTempPassword').props().tempPassword;
|
|
})()
|
|
);
|
|
```
|
|
|
|
L'elemento `tempPassword` di `ReturnTempPassword` dovrebbe essere uguale a una stringa di almeno 8 caratteri.
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
|
|
const temp = mockedComponent.find('ReturnTempPassword').props()
|
|
.tempPassword;
|
|
return typeof temp === 'string' && temp.length >= 8;
|
|
})()
|
|
);
|
|
```
|
|
|
|
Il componente `ReturnTempPassword` dovrebbe visualizzare la password che crei come prop `tempPassword` all'interno dei tag `strong`.
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
const mockedComponent = Enzyme.mount(React.createElement(ResetPassword));
|
|
return (
|
|
mockedComponent.find('strong').text() ===
|
|
mockedComponent.find('ReturnTempPassword').props().tempPassword
|
|
);
|
|
})()
|
|
);
|
|
```
