# --description--
|
|
|
|
Per fornire la funzionalità delle domande vero/falso, abbiamo bisogno di un insieme di input che non consentano di selezionare entrambe le opzioni contemporaneamente.
|
|
|
|
All'interno di ogni elemento della lista, annida un elemento `label` e all'interno di ogni elemento `label` annida un elemento `input` con il `type` appropriato.
|
|
|
|
# --hints--
|
|
|
|
Dovresti annidare un elemento `label` all'interno del primo elemento `li`.
|
|
|
|
```js
|
|
assert.exists(document.querySelectorAll('ul.answers-list > li')?.[0]?.querySelector('label'));
|
|
```
|
|
|
|
Dovresti annidare un elemento `label` all'interno del secondo elemento `li`.
|
|
|
|
```js
|
|
assert.exists(document.querySelectorAll('ul.answers-list > li')?.[1]?.querySelector('label'));
|
|
```
|
|
|
|
Dovresti annidare un elemento `label` all'interno del terzo elemento `li`.
|
|
|
|
```js
|
|
assert.exists(document.querySelectorAll('ul.answers-list > li')?.[2]?.querySelector('label'));
|
|
```
|
|
|
|
Dovresti annidare un elemento `label` all'interno del quarto elemento `li`.
|
|
|
|
```js
|
|
assert.exists(document.querySelectorAll('ul.answers-list > li')?.[3]?.querySelector('label'));
|
|
```
|
|
|
|
Dovresti annidare un elemento `input` all'interno del primo elemento `label`.
|
|
|
|
```js
|
|
assert.exists(document.querySelectorAll('ul.answers-list > li')?.[0]?.querySelector('label')?.querySelector('input'));
|
|
```
|
|
|
|
Dovresti annidare un elemento `input` all'interno del secondo elemento `label`.
|
|
|
|
```js
|
|
assert.exists(document.querySelectorAll('ul.answers-list > li')?.[1]?.querySelector('label')?.querySelector('input'));
|
|
```
|
|
|
|
Dovresti annidare un elemento `input` all'interno del terzo elemento `label`.
|
|
|
|
```js
|
|
assert.exists(document.querySelectorAll('ul.answers-list > li')?.[2]?.querySelector('label')?.querySelector('input'));
|
|
```
|
|
|
|
Dovresti annidare un elemento `input` all'interno del quarto elemento `label`.
|
|
|
|
```js
|
|
assert.exists(document.querySelectorAll('ul.answers-list > li')?.[3]?.querySelector('label')?.querySelector('input'));
|
|
```
|
|
|
|
Dovresti dare al primo `input` un `type` del valore `radio`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('ul.answers-list > li > label > input')?.[0]?.type, 'radio');
|
|
```
|
|
|
|
Dovresti dare al secondo `input` un `type` del valore `radio`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('ul.answers-list > li > label > input')?.[1]?.type, 'radio');
|
|
```
|
|
|
|
Dovresti dare al terzo `input` un `type` del valore `radio`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('ul.answers-list > li > label > input')?.[2]?.type, 'radio');
|
|
```
|
|
|
|
Dovresti dare al quarto `input` un `type` del valore `radio`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('ul.answers-list > li > label > input')?.[3]?.type, 'radio');
|
