# --description--
|
|
|
|
我们可以只通过 HTML 来实现发送数据给服务器的表单，只需要给 `form` 元素添加 `action` 属性即可。
|
|
|
|
例如:
|
|
|
|
`<form action="/url-where-you-want-to-submit-form-data"></form>`
|
|
|
|
# --instructions--
|
|
|
|
把现有的 `input` 输入框放到一个新建的 `form` 表单里，然后设置表单的 `action` 属性为 `"https://freecatphotoapp.com/submit-cat-photo"`。
|
|
|
|
# --hints--
|
|
|
|
现有的 `input` 输入框应位于新创建的 `form` 表单里面。
|
|
|
|
```js
|
|
const inputElem = document.querySelector('form input');
|
|
assert(
|
|
inputElem.getAttribute('type') === 'text' &&
|
|
inputElem.getAttribute('placeholder') === 'cat photo URL'
|
|
);
|
|
```
|
|
|
|
表单的 `action` 属性值应设置为 `https://freecatphotoapp.com/submit-cat-photo`。
|
|
|
|
```js
|
|
assert(
|
|
$('form').attr('action') === 'https://freecatphotoapp.com/submit-cat-photo'
|
|
);
|
|
```
|
|
|
|
`form` 元素应有开始标签和结束标签。
|
|
|
|
```js
|
|
assert(
|
|
code.match(/<\/form>/g) &&
|
|
code.match(/<form [^<]*>/g) &&
|
|
code.match(/<\/form>/g).length === code.match(/<form [^<]*>/g).length
|
|
);
|
|
```
|
|
|
