# --description--
|
|
|
|
Gli elementi `a` (*anchor*) possono essere anche utilizzati per creare collegamenti interni per saltare a diverse sezioni di una pagina web.
|
|
|
|
Per creare un link interno assegna l'attributo `href` di un link a un simbolo di hash `#` seguito dal valore dell'attributo `id` dell'elemento a cui desideri creare il collegamento, solitamente più in basso nella pagina. Devi quindi aggiungere lo stesso attributo `id` all'elemento a cui ti stai collegando. Un `id` è un attributo che identifica in modo univoco un elemento.
|
|
|
|
Di seguito è riportato un esempio di collegamento interno e il suo elemento di destinazione:
|
|
|
|
```html
|
|
<a href="#contacts-header">Contacts</a>
|
|
...
|
|
<h2 id="contacts-header">Contacts</h2>
|
|
```
|
|
|
|
Quando gli utenti cliccheranno sul link `Contacts`, saranno portati alla sezione della pagina web con l'elemento di intestazione **Contacts**.
|
|
|
|
# --instructions--
|
|
|
|
Cambia il tuo link esterno in un link interno modificando l'attributo `href` in `#footer` e il testo da `cat photos` a `Jump to Bottom`.
|
|
|
|
Rimuovi l'attributo `target="_blank"` dal tag di ancoraggio perché questo farebbe aprire il documento collegato in una nuova scheda del browser.
|
|
|
|
Quindi aggiungi un attributo `id` con un valore di `footer` all'elemento `<footer>` in fondo alla pagina.
|
|
|
|
# --hints--
|
|
|
|
Ci dovrebbe essere un solo tag di ancoraggio nella tua pagina.
|
|
|
|
```js
|
|
assert($('a').length == 1);
|
|
```
|
|
|
|
Ci dovrebbe essere solo un tag `footer` nella tua pagina.
|
|
|
|
```js
|
|
assert($('footer').length == 1);
|
|
```
|
|
|
|
Il tag `a` dovrebbe avere un attributo `href` impostato a "#footer".
|
|
|
|
```js
|
|
assert($('a').eq(0).attr('href') == '#footer');
|
|
```
|
|
|
|
Il tag `a` non dovrebbe avere un attributo `target`.
|
|
|
|
```js
|
|
assert(
|
|
typeof $('a').eq(0).attr('target') == typeof undefined ||
|
|
$('a').eq(0).attr('target') == true
|
|
);
|
|
```
|
|
|
|
Il testo `a` dovrebbe essere "Jump to Bottom".
|
|
|
|
```js
|
|
assert(
|
|
$('a')
|
|
.eq(0)
|
|
.text()
|
|
.match(/Jump to Bottom/gi)
|
|
);
|
|
```
|
|
|
|
Il tag `footer` dovrebbe avere un attributo `id` impostato a "footer".
|
|
|
|
```js
|
|
assert($('footer').eq(0).attr('id') == 'footer');
|
|
```
