# --description--
|
|
|
|
Bootstrap 的 `button` 元素有着独有的、比默认 HTML 按钮更好的样式风格。
|
|
|
|
在较大的小猫图片下方创建新的 `button` 元素。 为它添加 `btn` 与 `btn-default` 两个 classes 和 `Like` 文本。
|
|
|
|
# --hints--
|
|
|
|
应创建一个新的包含 `Like` 文本的 `button` 元素。
|
|
|
|
```js
|
|
assert(
|
|
new RegExp('like', 'gi').test($('button').text()) &&
|
|
$('img.img-responsive + button.btn').length > 0
|
|
);
|
|
```
|
|
|
|
新的按钮元素应该有两个 classes: `btn` 和 `btn-default`。
|
|
|
|
```js
|
|
assert($('button').hasClass('btn') && $('button').hasClass('btn-default'));
|
|
```
|
|
|
|
确保所有 `button` 元素都有闭合标签。
|
|
|
|
```js
|
|
assert(
|
|
code.match(/<\/button>/g) &&
|
|
code.match(/<button/g) &&
|
|
code.match(/<\/button>/g).length === code.match(/<button/g).length
|
|
);
|
|
```
