--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
元素是一个行内元素,用于在一个页面上显示日期或时间。 datetime
属性包含的有效格式。 辅助设备可以获取这个值。 这个属性也有助于避免混乱,因为它规定了时间的标准化版本,甚至可以在文本中以非正式的方式或学术方式使用它。
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 格斗的调查结果出来了! 用 time
标签包裹文本 Thursday, September 15<sup>th</sup>
,添加一个 datetime
属性,将属性值设置为 2016-09-15
。
--hints--
应存在一个 time
元素和一个内容文本为 Thank you to everyone for responding to Master Camper Cat's survey.
的 p
元素。
assert(timeElement);
time
元素的内容文本应为 Thursday, September 15<sup>th</sup>
。
assert(
timeElement &&
timeElement?.innerHTML?.trim() === 'Thursday, September 15<sup>th</sup>'
);
time
元素应包含非空的 datetime
属性。
assert(datetimeAttr && datetimeAttr?.length);
datetime
的属性值应为 2016-09-15
。
assert(datetimeAttr === '2016-09-15');
