# --description--
|
|
|
|
When a form gets submitted, the data is sent to the server and includes entries for the options selected. Inputs of type `radio` and `checkbox` report their values from the `value` attribute.
|
|
|
|
For example:
|
|
|
|
```html
|
|
<label for="indoor">
|
|
<input id="indoor" value="indoor" type="radio" name="indoor-outdoor">Indoor
|
|
</label>
|
|
<label for="outdoor">
|
|
<input id="outdoor" value="outdoor" type="radio" name="indoor-outdoor">Outdoor
|
|
</label>
|
|
```
|
|
|
|
Here, you have two `radio` inputs. When the user submits the form with the `indoor` option selected, the form data will include the line: `indoor-outdoor=indoor`. This is from the `name` and `value` attributes of the "indoor" input.
|
|
|
|
If you omit the `value` attribute, the submitted form data uses the default value, which is `on`. In this scenario, if the user clicked the "indoor" option and submitted the form, the resulting form data would be `indoor-outdoor=on`, which is not useful. So the `value` attribute needs to be set to something to identify the option.
|
|
|
|
# --instructions--
|
|
|
|
Give each of the `radio` and `checkbox` inputs the `value` attribute. Use the input label text, in lowercase, as the value for the attribute.
|
|
|
|
# --hints--
|
|
|
|
One of your radio buttons should have the `value` attribute of `indoor`.
|
|
|
|
```js
|
|
assert(
|
|
$('label:contains("Indoor") > input[type="radio"]').filter("[value='indoor']")
|
|
.length > 0
|
|
);
|
|
```
|
|
|
|
One of your radio buttons should have the `value` attribute of `outdoor`.
|
|
|
|
```js
|
|
assert(
|
|
$('label:contains("Outdoor") > input[type="radio"]').filter(
|
|
"[value='outdoor']"
|
|
).length > 0
|
|
);
|
|
```
|
|
|
|
One of your checkboxes should have the `value` attribute of `loving`.
|
|
|
|
```js
|
|
assert(
|
|
$('label:contains("Loving") > input[type="checkbox"]').filter(
|
|
"[value='loving']"
|
|
).length > 0
|
|
);
|
|
```
|
|
|
|
One of your checkboxes should have the `value` attribute of `lazy`.
|
|
|
|
```js
|
|
assert(
|
|
$('label:contains("Lazy") > input[type="checkbox"]').filter("[value='lazy']")
|
|
.length > 0
|
|
);
|
|
```
|
|
|
|
One of your checkboxes should have the `value` attribute of `energetic`.
|
|
|
|
```js
|
|
assert(
|
|
$('label:contains("Energetic") > input[type="checkbox"]').filter(
|
|
"[value='energetic']"
|
|
).length > 0
|
|
);
|
|
```
