# --description--
|
||
|
||
你可以用 `a`（Anchor，简写为 a）来实现网页间的跳转。
|
||
|
||
`a` 需要一个 `href` 属性指向跳转的目的地。 同时，它还应有内容。 例如：
|
||
|
||
`<a href="https://freecodecamp.org">链接到 freeCodeCamp</a>`
|
||
|
||
在浏览器中，以上的标签会将文字 **"链接到 freeCodeCamp"** 展示成一个可点击的超链接。 点击该文本就会跳转到 **`https://freecodecamp.org`**。
|
||
|
||
# --instructions--
|
||
|
||
创建一个内容文本为 “cat photos” 的 `a` 元素，并将其 `href` 属性值设置为 `https://freecatphotoapp.com`。
|
||
|
||
# --hints--
|
||
|
||
`a` 元素的锚文本应为 “cat photos”。
|
||
|
||
```js
|
||
assert(/cat photos/gi.test($('a').text()));
|
||
```
|
||
|
||
你的 `a` 元素应链接到 `https://freecatphotoapp.com`。
|
||
|
||
```js
|
||
assert(/https:\/\/(www\.)?freecatphotoapp\.com/gi.test($('a').attr('href')));
|
||
```
|
||
|
||
确保 `a` 元素有结束标签。
|
||
|
||
```js
|
||
assert(
|
||
code.match(/<\/a>/g) &&
|
||
code.match(/<\/a>/g).length === code.match(/<a/g).length
|
||
);
|
||
```
