# --description--
|
|
|
|
You can use <dfn>radio buttons</dfn> for questions where you want the user to only give you one answer out of multiple options.
|
|
|
|
Radio buttons are a type of `input`.
|
|
|
|
Each of your radio buttons can be nested within its own `label` element. By wrapping an `input` element inside of a `label` element it will automatically associate the radio button input with the label element surrounding it.
|
|
|
|
All related radio buttons should have the same `name` attribute to create a radio button group. By creating a radio group, selecting any single radio button will automatically deselect the other buttons within the same group ensuring only one answer is provided by the user.
|
|
|
|
Here's an example of a radio button:
|
|
|
|
```html
|
|
<label>
|
|
<input type="radio" name="indoor-outdoor">Indoor
|
|
</label>
|
|
```
|
|
|
|
It is considered best practice to set a `for` attribute on the `label` element, with a value that matches the value of the `id` attribute of the `input` element. This allows assistive technologies to create a linked relationship between the label and the related `input` element. For example:
|
|
|
|
```html
|
|
<input id="indoor" type="radio" name="indoor-outdoor">
|
|
<label for="indoor">Indoor</label>
|
|
```
|
|
|
|
We can also nest the `input` element within the `label` tags:
|
|
|
|
```html
|
|
<label for="indoor">
|
|
<input id="indoor" type="radio" name="indoor-outdoor">Indoor
|
|
</label>
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Add a pair of radio buttons to your form, each nested in its own `label` element. One should have the option of `indoor` and the other should have the option of `outdoor`. Both should share the `name` attribute of `indoor-outdoor` to create a radio group.
|
|
|
|
# --hints--
|
|
|
|
Your page should have two `radio` button elements.
|
|
|
|
```js
|
|
assert($('input[type="radio"]').length > 1);
|
|
```
|
|
|
|
Your radio buttons should be given the `name` attribute of `indoor-outdoor`.
|
|
|
|
```js
|
|
assert($('input[type="radio"]').filter("[name='indoor-outdoor']").length > 1);
|
|
```
|
|
|
|
Each of your two radio button elements should be nested in its own `label` element.
|
|
|
|
```js
|
|
assert($('label > input[type="radio"]:only-child').length > 1);
|
|
```
|
|
|
|
Each of your `label` elements should have a closing tag.
|
|
|
|
```js
|
|
assert(
|
|
code.match(/<\/label>/g) &&
|
|
code.match(/<label/g) &&
|
|
code.match(/<\/label>/g).length === code.match(/<label/g).length
|
|
);
|
|
```
|
|
|
|
One of your radio buttons should have the label `indoor`.
|
|
|
|
```js
|
|
assert(
|
|
$('label')
|
|
.text()
|
|
.match(/indoor/gi)
|
|
);
|
|
```
|
|
|
|
One of your radio buttons should have the label `outdoor`.
|
|
|
|
```js
|
|
assert(
|
|
$('label')
|
|
.text()
|
|
.match(/outdoor/gi)
|
|
);
|
|
```
|
|
|
|
Each of your radio button elements should be added within the `form` tag.
|
|
|
|
```js
|
|
assert($('label').parent().get(0).tagName.match('FORM'));
|
|
```
|
