# --description--
|
|
|
|
También puedes apuntar a elementos por su atributo id.
|
|
|
|
Primero apunta a tu elemento `button` con el id `target3` usando el selector `$("#target3")`.
|
|
|
|
Ten en cuenta que, al igual que con las declaraciones CSS, escribes un `#` antes del nombre del id.
|
|
|
|
Luego usa la función `.addClass()` de jQuery para agregar las clases `animated` y `fadeOut`.
|
|
|
|
Así es como harás que el elemento `button` con el id `target6` se desvanezca:
|
|
|
|
```js
|
|
$("#target6").addClass("animated fadeOut");
|
|
```
|
|
|
|
# --hints--
|
|
|
|
Debes seleccionar el elemento `button` con el `id` de `target3` y utilizar la función jQuery `addClass()` para darle la clase `animated`.
|
|
|
|
```js
|
|
assert($('#target3').hasClass('animated'));
|
|
```
|
|
|
|
Debes seleccionar el elemento con el id `target3` y utilizar la función jQuery `addClass()` para darle la clase `fadeOut`.
|
|
|
|
```js
|
|
assert(
|
|
($('#target3').hasClass('fadeOut') || $('#target3').hasClass('fadeout')) &&
|
|
code.match(/\$\(\s*.#target3.\s*\)/g)
|
|
);
|
|
```
|
|
|
|
Debes usar solo jQuery para agregar estas clases al elemento.
|
|
|
|
```js
|
|
assert(!code.match(/class.*animated/g));
|
|
```
