# --description--
|
|
|
|
You can build web forms that actually submit data to a server using nothing more than pure HTML. You can do this by specifying an `action` attribute on your `form` element.
|
|
|
|
For example:
|
|
|
|
```html
|
|
<form action="/url-where-you-want-to-submit-form-data">
|
|
<input>
|
|
</form>
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Nest the existing `input` element inside a `form` element and assign `"https://www.freecatphotoapp.com/submit-cat-photo"` to the `action` attribute of the `form` element.
|
|
|
|
# --hints--
|
|
|
|
The existing `input` element should be nested within a `form` element.
|
|
|
|
```js
|
|
const inputElem = document.querySelector('form input');
|
|
assert(
|
|
inputElem.getAttribute('type') === 'text' &&
|
|
inputElem.getAttribute('placeholder') === 'cat photo URL'
|
|
);
|
|
```
|
|
|
|
Your `form` should have an `action` attribute which is set to `https://www.freecatphotoapp.com/submit-cat-photo`.
|
|
|
|
```js
|
|
const action = $('form').attr('action');
|
|
assert(action.match(/^https:\/\/(www\.)?freecatphotoapp\.com\/submit-cat-photo$/i))
|
|
```
|
|
|
|
Your `form` element should have well-formed open and close tags.
|
|
|
|
```js
|
|
assert(
|
|
code.match(/<\/form>/g) &&
|
|
code.match(/<form [^<]*>/g) &&
|
|
code.match(/<\/form>/g).length === code.match(/<form [^<]*>/g).length
|
|
);
|
|
```
|
|
