Description
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
属性保存了日期的有效格式,辅助设备可以访问这个值。通过标准化时间格式,即使时间在文本中是以非正式的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
time
标签包含文本 "Thursday, September 15<sup>th</sup>",并将datetime
属性设置为 "2016-09-15"。
Tests
tests:
- text: '<code>time</code>标签应该包含文本"Thursday, September 15<sup>th</sup>"。'
testString: assert(timeElement.length);
- text: '<code>time</code>标签应该有 1 个非空的<code>datetime</code>属性。'
testString: assert(timeElement.length && $(timeElement).html().trim() === "Thursday, September 15<sup>th</sup>");
- text: '<code>datetime</code>属性的值应该为 2016-09-15。'
testString: assert(datetimeAttr && datetimeAttr.length);
- text: '确保<code>time</code>标签是闭合的。'
testString: assert(datetimeAttr === "2016-09-15");
