# --description--
|
||
|
|
|
||
|
|
Puedes requerir campos específicos de un formulario para que tu usuario no pueda enviarlo hasta que no los haya rellenado.
|
||
|
|
|
||
|
|
Por ejemplo, si deseas hacer obligatorio un campo de entrada de texto, puedes agregar el atributo `required` dentro de tu elemento `input`, de esta forma: `<input type="text" required>`
|
||
|
|
|
||
|
|
# --instructions--
|
||
|
|
|
||
|
|
Convierte tu entrada de texto `input` en un campo obligatorio `required` para que tu usuario no pueda enviar el formulario sin completar este campo.
|
||
|
|
|
||
|
|
Luego intenta enviar el formulario sin introducir ningún texto. ¿Ves cómo tu formulario HTML5 te notifica que el campo es obligatorio?
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
Tu elemento de entrada de texto `input` debe tener el atributo `required`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert($('input').prop('required'));
|
||
|
|
```
|
||
|
