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:

<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.

Tests

tests:
  - text: One of your radio buttons should have the <code>value</code> attribute of <code>indoor</code>.
    testString: assert($('label:contains("Indoor") > input[type="radio"]').filter("[value='indoor']").length > 0);
  - text: One of your radio buttons should have the <code>value</code> attribute of <code>outdoor</code>.
    testString: assert($('label:contains("Outdoor") > input[type="radio"]').filter("[value='outdoor']").length > 0);
  - text: One of your checkboxes should have the <code>value</code> attribute of <code>loving</code>.
    testString: assert($('label:contains("Loving") > input[type="checkbox"]').filter("[value='loving']").length > 0);
  - text: One of your checkboxes should have the <code>value</code> attribute of <code>lazy</code>.
    testString: assert($('label:contains("Lazy") > input[type="checkbox"]').filter("[value='lazy']").length > 0);
  - text: One of your checkboxes should have the <code>value</code> attribute of <code>energetic</code>.
    testString: assert($('label:contains("Energetic") > input[type="checkbox"]').filter("[value='energetic']").length > 0);
