Description
radio button
s 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:
<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 child input
element. For example:
<label for="indoor">
<input id="indoor" type="radio" name="indoor-outdoor">Indoor
</label>
Instructions
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.
Tests
tests:
- text: Your page should have two radio button elements.
testString: assert($('input[type="radio"]').length > 1);
- text: Give your radio buttons the <code>name</code> attribute of <code>indoor-outdoor</code>.
testString: assert($('input[type="radio"]').filter("[name='indoor-outdoor']").length > 1);
- text: Each of your two radio button elements should be nested in its own <code>label</code> element.
testString: assert($('label > input[type="radio"]:only-child').length > 1);
- text: Make sure each of your <code>label</code> elements has a closing tag.
testString: assert((code.match(/<\/label>/g) && code.match(/<label/g) && code.match(/<\/label>/g).length === code.match(/<label/g).length));
- text: One of your radio buttons should have the label <code>indoor</code>.
testString: assert($("label").text().match(/indoor/gi));
- text: One of your radio buttons should have the label <code>outdoor</code>.
testString: assert($("label").text().match(/outdoor/gi));
- text: Each of your radio button elements should be added within the <code>form</code> tag.
testString: assert($("label").parent().get(0).tagName.match('FORM'));
