# --description--
|
|
|
|
Ogni elemento HTML ha un elemento `parent` (genitore) dal quale eredita (`inherits`) delle proprietà.
|
|
|
|
Ad esempio, il tuo elemento `jQuery Playground` di tipo `h3` ha l'elemento genitore di `<div class="container-fluid">`, che a sua volta ha il genitore `body`.
|
|
|
|
jQuery ha una funzione chiamata `parent()` che consente di accedere al genitore di qualsiasi elemento selezionato.
|
|
|
|
Ecco un esempio di come utilizzare la funzione `parent()` per dare al genitore dell'elemento `left-well` un colore di sfondo di blu:
|
|
|
|
```js
|
|
$("#left-well").parent().css("background-color", "blue")
|
|
```
|
|
|
|
Dai al genitore dell'elemento `#target1` un colore di sfondo rosso.
|
|
|
|
# --hints--
|
|
|
|
Il tuo elemento `left-well` dovrebbe avere uno sfondo rosso.
|
|
|
|
```js
|
|
assert(
|
|
$('#left-well').css('background-color') === 'red' ||
|
|
$('#left-well').css('background-color') === 'rgb(255, 0, 0)' ||
|
|
$('#left-well').css('background-color').toLowerCase() === '#ff0000' ||
|
|
$('#left-well').css('background-color').toLowerCase() === '#f00'
|
|
);
|
|
```
|
|
|
|
Dovresti usare la funzione `.parent()` per modificare questo elemento.
|
|
|
|
```js
|
|
assert(code.match(/\.parent\s*\(\s*\)\s*\.css/g));
|
|
```
|
|
|
|
Il metodo `.parent()` dovrebbe essere chiamato sull'elemento `#target1`.
|
|
|
|
```js
|
|
assert(
|
|
code.match(/\$\s*?\(\s*?(?:'|")\s*?#target1\s*?(?:'|")\s*?\)\s*?\.parent/gi)
|
|
);
|
|
```
|
|
|
|
Dovresti usare solo jQuery per aggiungere queste classi all'elemento.
|
|
|
|
```js
|
|
assert(code.match(/<div class="well" id="left-well">/g));
|
|
```
