# --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
|
|
);
|
|
```
|
