# --description--
|
|
|
|
El texto provisional es lo que se muestra en tu elemento de entrada `input` antes de que el usuario haya ingresado nada.
|
|
|
|
Puedes crear texto provisional así:
|
|
|
|
```html
|
|
<input type="text" placeholder="this is placeholder text">
|
|
```
|
|
|
|
**Nota:** Recuerda que los elementos `input` se cierran solos.
|
|
|
|
# --instructions--
|
|
|
|
Establece el valor de `placeholder` de tu `input` de texto en "cat photo URL".
|
|
|
|
# --hints--
|
|
|
|
Debes agregar un atributo `placeholder` al elemento existente `input` de texto.
|
|
|
|
```js
|
|
assert($('input[placeholder]').length > 0);
|
|
```
|
|
|
|
Debes establecer el valor de tu atributo `placeholder` en `cat photo URL`.
|
|
|
|
```js
|
|
assert(
|
|
$('input') &&
|
|
$('input').attr('placeholder') &&
|
|
$('input')
|
|
.attr('placeholder')
|
|
.match(/cat\s+photo\s+URL/gi)
|
|
);
|
|
```
|
|
|
|
El elemento `input` terminado no debe tener una etiqueta de cierre.
|
|
|
|
```js
|
|
assert(!code.match(/<input.*\/?>.*<\/input>/gi));
|
|
```
|
|
|
|
El elemento `input` terminado debe tener una sintaxis válida.
|
|
|
|
```js
|
|
assert($('input[type=text]').length > 0);
|
|
```
