# --description--
|
|
|
|
Puedes construir formularios web que realmente envíen datos a un servidor usando sólo HTML puro. Puedes hacer esto especificando un atributo `action` en tu elemento `form`.
|
|
|
|
Por ejemplo:
|
|
|
|
```html
|
|
<form action="/url-where-you-want-to-submit-form-data">
|
|
<input>
|
|
</form>
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Anida el elemento `input` existente dentro de un elemento `form` y asigna `"https://freecatphotoapp.com/submit-cat-photo"` al atributo `action` del elemento `form`.
|
|
|
|
# --hints--
|
|
|
|
El elemento `input` existente debe anidarse dentro de un elemento `form`.
|
|
|
|
```js
|
|
const inputElem = document.querySelector('form input');
|
|
assert(
|
|
inputElem.getAttribute('type') === 'text' &&
|
|
inputElem.getAttribute('placeholder') === 'cat photo URL'
|
|
);
|
|
```
|
|
|
|
Tu formulario `form` debe tener un atributo `action` que esté establecido como `https://freecatphotoapp.com/submit-cat-photo`
|
|
|
|
```js
|
|
assert(
|
|
$('form').attr('action') === 'https://freecatphotoapp.com/submit-cat-photo'
|
|
);
|
|
```
|
|
|
|
Tu elemento `form` debe tener etiquetas correctamente abiertas y cerradas.
|
|
|
|
```js
|
|
assert(
|
|
code.match(/<\/form>/g) &&
|
|
code.match(/<form [^<]*>/g) &&
|
|
code.match(/<\/form>/g).length === code.match(/<form [^<]*>/g).length
|
|
);
|
|
```
