# --description--

讓我們來給表單添加一個 `submit`（提交）按鈕。 點擊提交按鈕時，表單中的數據將會被髮送到 `action` 屬性指定的 URL 上。

例如：

```html
<button type="submit">this button submits the form</button>
```

# --instructions--

在 `form` 的底部創建一個按鈕，按鈕的類型爲 `submit`，文本爲 `Submit`。

# --hints--

你的 `form` 裏面應該有一個 `button`。

```js
assert($('form').children('button').length > 0);
```

按鈕的 `type` 屬性值應爲 `submit`。

```js
assert($('button').attr('type') === 'submit');
```

提交按鈕的文本應爲 `Submit` 。

```js
assert(
  $('button')
    .text()
    .match(/^\s*submit\s*$/gi)
);
```

`button` 元素應有結束標籤。

```js
assert(
  code.match(/<\/button>/g) &&
    code.match(/<button/g) &&
    code.match(/<\/button>/g).length === code.match(/<button/g).length
);
```
