# --description--
|
|
|
|
Ahora conoces tres maneras de seleccionar elementos: por tipo: `$("button")`, por clase: `$(".btn")`, y por id `$("#target1")`.
|
|
|
|
Aunque es posible agregar múltiples clases en una sola llamada `.addClass()`, vamos a agregarlos al mismo elemento de *tres maneras diferentes*.
|
|
|
|
Usando `.addClass()`, agrega solo una clase a la vez al mismo elemento, de tres maneras diferentes:
|
|
|
|
Agrega la clase `animated` a todos los elementos con el tipo `button`.
|
|
|
|
Agrega la clase `shake` a todos los botones con la clase `.btn`.
|
|
|
|
Agrega la clase `btn-primary` al botón con id `#target1`.
|
|
|
|
**Nota:** Solo debes apuntar a un elemento y agregar solo una clase a la vez. En total, tus tres selectores individuales terminarán agregando las tres clases `shake`, `animated`, y `btn-primary` a `#target1`.
|
|
|
|
# --hints--
|
|
|
|
Tu código debe usar el selector `$("button")`.
|
|
|
|
```js
|
|
assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?button\s*?(?:'|")/gi));
|
|
```
|
|
|
|
Tu código debe usar el selector `$(".btn")`.
|
|
|
|
```js
|
|
assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?\.btn\s*?(?:'|")/gi));
|
|
```
|
|
|
|
Tu código debe usar el selector `$("#target1")`.
|
|
|
|
```js
|
|
assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?#target1\s*?(?:'|")/gi));
|
|
```
|
|
|
|
Solo debes agregar una clase con cada uno de tus tres selectores.
|
|
|
|
```js
|
|
assert(
|
|
code.match(/addClass/g) &&
|
|
code.match(/addClass\s*?\(\s*?('|")\s*?[\w-]+\s*?\1\s*?\)/g).length > 2
|
|
);
|
|
```
|
|
|
|
Tu elemento `#target1` debe tener las clases `animated`, `shake` y `btn-primary`.
|
|
|
|
```js
|
|
assert(
|
|
$('#target1').hasClass('animated') &&
|
|
$('#target1').hasClass('shake') &&
|
|
$('#target1').hasClass('btn-primary')
|
|
);
|
|
```
|
|
|
|
Solo debes usar jQuery para agregar estas clases al elemento.
|
|
|
|
```js
|
|
assert(!code.match(/class.*animated/g));
|
|
```
