# --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`.
|
|
|
|
# --hints--
|
|
|
|
You should create an input element for your radio button. Check the syntax.
|
|
|
|
```js
|
|
assert($('form > input').length >= 2);
|
|
```
|
|
|
|
Your `input` element should have an opening tag, but not a closing tag.
|
|
|
|
```js
|
|
assert($('form > input') && !code.match(/<\/input\>/g));
|
|
```
|
|
|
|
You should only have added one input element for your radio button. Remove any extras.
|
|
|
|
```js
|
|
assert($('form > input').length === 2);
|
|
```
|
|
|
|
Your new `input` element should be above the existing `input` with `type` attribute set to `text`. You have them in the wrong order.
|
|
|
|
```js
|
|
const existingInputElem = document.querySelector('form > input[type="text"]');
|
|
assert(
|
|
existingInputElem &&
|
|
existingInputElem.previousElementSibling.nodeName === 'INPUT'
|
|
);
|
|
```
|
|
|
|
Your new `input` element does not have a `type` attribute. Check that there is a space after the opening tag's name.
|
|
|
|
```js
|
|
assert($('input')[0].hasAttribute('type'));
|
|
```
|
|
|
|
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.
|
|
|
|
```js
|
|
assert(
|
|
$('input')[0]
|
|
.getAttribute('type')
|
|
.match(/^radio$/i)
|
|
);
|
|
```
|
|
|
|
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.
|
|
|
|
```js
|
|
assert(!/\<\s*input\s+type\s*=\s*radio/i.test(code));
|
|
```
|
|
|
|
The `radio` button's ` Indoor` text should be located after it instead of before it.
|
|
|
|
```js
|
|
const radioInputElem = $('input')[0];
|
|
assert(!radioInputElem.previousSibling.nodeValue.match(/Indoor/i));
|
|
```
|
|
|
|
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.
|
|
|
|
```js
|
|
const radioInputElem = $('input')[0];
|
|
assert(
|
|
radioInputElem.nextSibling.nodeValue.replace(/\s+/g, ' ').match(/ Indoor/i)
|
|
);
|
|
```
