# --description--
|
|
|
|
To prevent a user from submitting your form when required information is missing, you need to add the `required` attribute to an `input` element. There's no need to set a value to the `required` attribute. Instead, just add the word `required` to the `input` element, making sure there is space between it and other attributes.
|
|
|
|
# --hints--
|
|
|
|
You have either deleted your `input` element or it has invalid syntax. All attributes' values should be surrounded by quotation marks.
|
|
|
|
```js
|
|
assert($('input').length);
|
|
```
|
|
|
|
Your `form` should only contain the `input` element. Remove any HTML additional elements or text within the `form` element.
|
|
|
|
```js
|
|
assert(
|
|
$('form')[0].children.length === 1 &&
|
|
$('form')[0].innerText.trim().length === 0
|
|
);
|
|
```
|
|
|
|
Your `input` element should have a `required` attribute. Remember, you just add the word `required` inside the `input` element's tag.
|
|
|
|
```js
|
|
assert($('input')[0].hasAttribute('required'));
|
|
```
|
|
|
|
A value should not be given to the `required` attribute.
|
|
|
|
```js
|
|
assert($('input')[0].getAttribute('required') === '');
|
|
```
