# --description--
|

|
|
|
||
|
|
按照無障礙最佳實踐，將第二個 `fieldset` 內的 `input` 元素和 `label` 元素關聯起來。
|
||
|
|
|
||
|
|
使用 `personal-account`、`business-account` 和 `terms-and-conditions` 作爲對應的 `id` 屬性的值。
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
第一個 `input` 元素的 `id` 應該爲 `personal-account`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(document.querySelectorAll('fieldset:nth-of-type(2) input')?.[0]?.matches('#personal-account'))
|
||
|
|
```
|
||
|
|
|
||
|
|
第二個 `input` 元素的 `id` 應該爲 `business-account`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(document.querySelectorAll('fieldset:nth-of-type(2) input')?.[1]?.matches('#business-account'))
|
||
|
|
```
|
||
|
|
|
||
|
|
第三個 `input` 元素的 `id` 應該爲 `terms-and-conditions`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(document.querySelectorAll('fieldset:nth-of-type(2) input')?.[2]?.matches('#terms-and-conditions'))
|
||
|
|
```
|
||
|
|
|
||
|
|
第一個 `label` 元素的 `for` 屬性應該爲 `personal-account`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(document.querySelectorAll('fieldset:nth-of-type(2) label')?.[0]?.matches('label[for="personal-account"]'))
|
||
|
|
```
|
||
|
|
|
||
|
|
第二個 `label` 元素的 `for` 屬性應該爲 `business-account`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(document.querySelectorAll('fieldset:nth-of-type(2) label')?.[1]?.matches('label[for="business-account"]'))
|
||
|
|
```
|
||
|
|
|
||
|
|
第三個 `label` 元素的 `for` 屬性應該爲 `terms-and-conditions`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(document.querySelectorAll('fieldset:nth-of-type(2) label')?.[2]?.matches('label[for="terms-and-conditions"]'))
|
||
|
|
```
