你可以通过把元素嵌套进 a
里使其变成一个链接。
如果我们要把图片嵌套进 a
元素, 可以这样写:
<a href="#"><img src="https://cdn.freecodecamp.org/curriculum/cat-photo-app/relaxing-cat.jpg" alt="Three kittens running towards the camera."></a>
如果把 a
的 href
属性值设置为 #
,创建的是一个死链接(不跳转到其他画面)。
--instructions--
请把现存的图片嵌套进 a
( 锚点)元素中。
完成后,请你把鼠标光标悬停在你的图像上, 鼠标光标将变成点击光标。 于是图片就变成了链接。
--hints--
应将 img
嵌套进 a
元素中。
assert($('a').children('img').length > 0);
a
的 href
属性值应为 #
。
assert(new RegExp('#').test($('a').children('img').parent().attr('href')));
每个 a
元素都应该有一个结束标签。
assert(
code.match(/<\/a>/g) &&
code.match(/<a/g) &&
code.match(/<\/a>/g).length === code.match(/<a/g).length
);
