# --description--

指定表單元素的 `type` 屬性對瀏覽器預期表單的數據類型至關重要。 如果未指定 `type`，瀏覽器會使用默認值 `text`。
|
||
|
|
|
||
|
|
給前兩個 `input` 元素設置其 `type` 屬性值爲 `text`，第三個 `type` 屬性值爲 `email`，第四個 `type` 屬性值爲 `password`。
|
||
|
|
|
||
|
|
`email` 類型只允許包含 `@` 以及域名中包含 `.` 的電子郵件。 `password` 類型會屏蔽輸入，如果網站沒有啓用 HTTPS 會警告。

應該給第一個 `input` 添加 `type` 其值爲 `text`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.equal(document.querySelector('input')?.type, 'text');
|
||
|
|
```
|
||
|
|
|
||
|
|
應該給第二個 `input` 添加 `type` 其值爲 `text`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.equal(document.querySelectorAll('input')?.[1]?.type, 'text');
|
||
|
|
```
|
||
|
|
|
||
|
|
應該給第三個 `input` 添加 `type` 其值爲 `email`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.equal(document.querySelectorAll('input')?.[2]?.type, 'email');
|
||
|
|
```
|
||
|
|
|
||
|
|
應該給第四個 `input` 添加 `type` 其值爲 `password`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.equal(document.querySelectorAll('input')?.[3]?.type, 'password');
|
||
|
|
```
