--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:
<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 cambiando 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.
assert($('a').length == 1);
Ci dovrebbe essere solo un tag footer nella tua pagina.
assert($('footer').length == 1);
Il tag a dovrebbe avere un attributo href impostato a "#footer".
assert($('a').eq(0).attr('href') == '#footer');
Il tag a non dovrebbe avere un attributo target.
assert(
typeof $('a').eq(0).attr('target') == typeof undefined ||
$('a').eq(0).attr('target') == true
);
Il testo a dovrebbe essere "Jump to Bottom".
assert(
$('a')
.eq(0)
.text()
.match(/Jump to Bottom/gi)
);
Il tag footer dovrebbe avere un attributo id impostato a "footer".
assert($('footer').eq(0).attr('id') == 'footer');
