# --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，注释的开始标签是 `<!--`，结束标签是 `-->`。
|
|
|
|

|
现在我们反其道而行之，去掉 `h1` 元素、`h2` 元素、`p` 元素的注释。
|
|
|
|
# --hints--
|
|
|
|
页面上应存在 `h1` 元素。
|
|
|
|
```js
|
|
assert($('h1').length > 0);
|
|
```
|
|
|
|
页面上应存在 `h2` 元素。
|
|
|
|
```js
|
|
assert($('h2').length > 0);
|
|
```
|
|
|
|
页面上应存在 `p` 元素。
|
|
|
|
```js
|
|
assert($('p').length > 0);
|
|
```
|
|
|
|
应删除注释的结束标签 `-->`。
|
|
|
|
```js
|
|
assert(!$('*:contains("-->")')[1]);
|
|
```
