# --description--

|
继续日期主题。HTML5 还引入了 `time` 标签与 `datetime` 属性来标准化时间。`time` 是一个行内标签，用于在页面中呈现日期或时间，而 `datetime` 属性用户设置日期的格式，辅助设备会获取这个值。通过标准化时间格式，即使时间在文本中是以非正式或口语化的形式编写，辅助设备依然可以获取准确的时间和日期。
|
|
|
|
举个例子：
|
|
|
|
`<p>Master Camper Cat officiated the cage match between Goro and Scorpion <time datetime="2013-02-13">last Wednesday</time>, which ended in a draw.</p>`
|
|
|
|
# --instructions--
|
|
|
|
Camper Cat 的比武大会的时间确定了！请使用 `time` 标签包裹文本 "Thursday, September 15<sup>th</sup>"，并将 `datetime` 的属性值设置为 "2016-09-15"。
|
|
|
|
# --hints--
|
|
|
|
应存在一个内容文本为 `Thank you to everyone for responding to Master Camper Cat's survey.` 的 `p` 元素和一个 `time` 元素。
|
|
|
|
```js
|
|
assert(timeElement.length);
|
|
```
|
|
|
|
`time` 元素的内容文本应为 `Thursday, September 15<sup>th</sup>`。
|
|
|
|
```js
|
|
assert(
|
|
timeElement.length &&
|
|
$(timeElement).html().trim() === 'Thursday, September 15<sup>th</sup>'
|
|
);
|
|
```
|
|
|
|
`time` 元素应包含非空的 `datetime` 属性。
|
|
|
|
```js
|
|
assert(datetimeAttr && datetimeAttr.length);
|
|
```
|
|
|
|
`datetime` 的属性值应为 `2016-09-15`。
|
|
|
|
```js
|
|
assert(datetimeAttr === '2016-09-15');
|
|
```
