title: 去除 HTML 的注释
|
|
---
|
|
|
|
## Description
|
|
<section id='description'>
|
|
注释的作用是给代码添加一些说明，方便团队合作或日后自己查看，但又不影响代码本身。
|
|
注释的另一个用途就是在不删除代码的前提下，让代码不起作用。
|
|
在 HTML 中，注释的开始标记是<code><!--</code>，结束标记是<code>--></code>。
|
|
</section>
|
|
|
|
## Instructions
|
|
<section id='instructions'>
|
|
现在我们反其道而行之，去掉<code>h1</code>元素、<code>h2</code>元素、<code>p</code>元素的注释。
|
|
</section>
|
|
|
|
## Tests
|
|
<section id='tests'>
|
|
|
|
```yml
|
|
tests:
|
|
- text: '确保网页中能看到<code>h1</code>元素。'
|
|
testString: assert($("h1").length > 0);
|
|
- text: '确保网页中能看到<code>h2</code>元素。'
|
|
testString: assert($("h2").length > 0);
|
|
- text: '确保网页中能看到<code>p</code>元素。'
|
|
testString: assert($("p").length > 0);
|
|
- text: '确保删除了注释的结束标记<code>--></code>。'
|
|
testString: assert(!$('*:contains("-->")')[1]);
|
|
|
|
```
