# --description--
|
|
|
|
記住：註釋的開始標記是 `<!--`，結束標記是 `-->`。
|
|
|
|
現在你需要在 `h2` 元素開始前終止註釋。
|
|
|
|
# --instructions--
|
|
|
|
註釋掉 `h1` 元素和 `p` 元素，保留 `h2` 元素。
|
|
|
|
# --hints--
|
|
|
|
應註釋掉 `h1` 元素，這樣它就從網頁上消失了。
|
|
|
|
```js
|
|
assert($('h1').length === 0);
|
|
```
|
|
|
|
`h2` 元素應保持原樣，這樣網頁上還能看到它。
|
|
|
|
```js
|
|
assert($('h2').length > 0);
|
|
```
|
|
|
|
應註釋掉 `p` 元素，這樣它就從網頁上消失了。
|
|
|
|
```js
|
|
assert($('p').length === 0);
|
|
```
|
|
|
|
每一個註釋都應以 `-->` 結尾。
|
|
|
|
```js
|
|
assert(code.match(/[^fc]-->/g).length > 1);
|
|
```
|
|
|
|
不要更改 `h1` 元素、`h2` 元素、`p` 元素的順序。
|
|
|
|
```js
|
|
assert(
|
|
code.match(/<([a-z0-9]){1,2}>/g)[0] === '<h1>' &&
|
|
code.match(/<([a-z0-9]){1,2}>/g)[1] === '<h2>' &&
|
|
code.match(/<([a-z0-9]){1,2}>/g)[2] === '<p>'
|
|
);
|
|
```
