## Description
|
||
|
|
<section id='description'>

|
|
|
||
|
|
You can use radio buttons for questions where you want only one answer out of multiple options.
|
||
|
|
|
||
|
|
Here is an example of a radio button with the option of `cat`: `<input type="radio"> cat`. Remember that `input` elements are <dfn>self-closing</dfn>.
|
||
|
|
|
||
|
|
Before the text input, add a radio button with the option `Indoor`.

## Tests
|

|
|
<section id='tests'>

|

|
|
```yml
|
||
|
|
tests:
|
||
|
|
- text: You should create an input element for your radio button. Check the syntax.
|
||
|
|
testString: assert( $('form > input').length >= 2 );
|
||
|
|
- text: Your `input` element should have an opening tag, but not a closing tag.
|
||
|
|
testString: assert( $('form > input') && !code.match(/<\/input\>/g) );
|
||
|
|
- text: You should only have added one input element for your radio button. Remove any extras.
|
||
|
|
testString: assert( $('form > input').length === 2 );
|
||
|
|
- text: Your new `input` element should be above the existing `input` with `type` attribute set to `text`. You have them in the wrong order.
|
||
|
|
testString: |
|
||
|
|
const existingInputElem = document.querySelector('form > input[type="text"]');
|
||
|
|
assert(
|
||
|
|
existingInputElem && existingInputElem.previousElementSibling.nodeName === 'INPUT'
|
||
|
|
);
|
||
|
|
- text: Your new `input` element does not have a `type` attribute. Check that there is a space after the opening tag's name.
|
||
|
|
testString: assert( $('input')[0].hasAttribute('type') );
|
||
|
|
- text: Your new `input` element should have a `type` attribute with the value `radio`. You have either omitted the value or have a typo. Remember that attribute values should be surrounded with quotation marks.
|
||
|
|
testString: assert( $('input')[0].getAttribute('type').match(/^radio$/i) );
|
||
|
|
- text: Although you have set the new `input` element's `type` attribute to `radio`, it is recommended to always surround the value of an attribute with quotation marks.
|
||
|
|
testString: assert( !/\<\s*input\s+type\s*=\s*radio/i.test(code) );
|
||
|
|
- text: The `radio` button's ` Indoor` text should be located after it instead of before it.
|
||
|
|
testString: |
|
||
|
|
const radioInputElem = $('input')[0];
|
||
|
|
assert( !radioInputElem.previousSibling.nodeValue.match(/Indoor/i) );
|
||
|
|
- text: The text ` Indoor` should be located directly to the right of your `radio` button. Make sure there is a space between the element and the text. You have either omitted the text or have a typo.
|
||
|
|
testString: |
|
||
|
|
const radioInputElem = $('input')[0];
|
||
|
|
assert( radioInputElem.nextSibling.nodeValue.replace(/\s+/g, ' ').match(/ Indoor/i) );
|
||
|
|
|
