# --description--
|
|
|
|
It is important to link each `input` to the corresponding `label` element. This provides assistive technology users with a visual reference to the input.
|
|
|
|
This is done by giving the `label` a `for` attribute, which contains the `id` of the `input`.
|
|
|
|
This section will take a student's name, email address, and date of birth. Give the `label` elements appropriate `for` attributes, as well as text content. Then, link the `input` elements to the corresponding `label` elements.
|
|
|
|
# --hints--
|
|
|
|
You should give the first `label` element an appropriate `for` attribute.
|
|
|
|
```js
|
|
assert.isAtLeast(document.querySelectorAll('label')?.[0]?.htmlFor?.length, 1);
|
|
```
|
|
|
|
You should give the second `label` element an appropriate `for` attribute.
|
|
|
|
```js
|
|
assert.isAtLeast(document.querySelectorAll('label')?.[1]?.htmlFor?.length, 1);
|
|
```
|
|
|
|
You should give the third `label` element an appropriate `for` attribute.
|
|
|
|
```js
|
|
assert.isAtLeast(document.querySelectorAll('label')?.[2]?.htmlFor?.length, 1);
|
|
```
|
|
|
|
You should give the first `label` element an appropriate text content.
|
|
|
|
```js
|
|
assert.isAtLeast(document.querySelectorAll('label')?.[0]?.textContent?.length, 1);
|
|
```
|
|
|
|
You should give the second `label` element an appropriate text content.
|
|
|
|
```js
|
|
assert.isAtLeast(document.querySelectorAll('label')?.[1]?.textContent?.length, 1);
|
|
```
|
|
|
|
You should give the third `label` element an appropriate text content.
|
|
|
|
```js
|
|
assert.isAtLeast(document.querySelectorAll('label')?.[2]?.textContent?.length, 1);
|
|
```
|
|
|
|
You should give the first `input` element an `id` attribute matching the `for` attribute of the first `label`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('input')?.[0]?.id, document.querySelectorAll('label')?.[0]?.htmlFor);
|
|
```
|
|
|
|
You should give the second `input` element an `id` attribute matching the `for` attribute of the second `label`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('input')?.[1]?.id, document.querySelectorAll('label')?.[1]?.htmlFor);
|
|
```
|
|
|
|
You should give the third `input` element an `id` attribute matching the `for` attribute of the third `label`.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('input')?.[2]?.id, document.querySelectorAll('label')?.[2]?.htmlFor);
|
|
```
|
|
|
|
You should not use the same `id` attribute for more than one `input` element.
|
|
|
|
```js
|
|
const id = (n) => document.querySelectorAll('input')?.[n]?.id;
|
|
assert.notEqual(id(0), id(1));
|
|
assert.notEqual(id(0), id(2));
|
|
assert.notEqual(id(1), id(2));
|
|
```
|
|
|
|
You should not use the same `for` attribute for more than one `label` element.
|
|
|
|
```js
|
|
const htmlFor = (n) => document.querySelectorAll('label')?.[n]?.htmlFor;
|
|
assert.notEqual(htmlFor(0), htmlFor(1));
|
|
assert.notEqual(htmlFor(0), htmlFor(2));
|
|
assert.notEqual(htmlFor(1), htmlFor(2));
|
|
```
