## Description
<section id='description'>
如果想使用 HTML 向服务器提交数据，可以给<code>form</code>添加<code>action</code>属性。
例如:
<code>&#60;form action="/url-where-you-want-to-submit-form-data"&#62;&#60;/form&#62;</code>
</section>

## Instructions
<section id='instructions'>
在<code>input</code>输入框外层创建一个<code>form</code>表单，然后设置表单的<code>action</code>属性为<code>"https://freecatphotoapp.com/submit-cat-photo"</code>。
</section>

## Tests

```yml
tests:
  - text: '在<code>input</code>输入框外层创建一个<code>form</code>表单。'
    testString: assert($("form") && $("form").children("input") && $("form").children("input").length > 0);
  - text: '确保表单的<code>action</code>属性为<code>"https://freecatphotoapp.com/submit-cat-photo"</code>。'
    testString: assert($("form").attr("action") === "https://freecatphotoapp.com/submit-cat-photo");
  - text: '确保表单有开始标记和结束标记。'
    testString: assert(code.match(/<\/form>/g) && code.match(/<form [^<]*>/g) && code.match(/<\/form>/g).length === code.match(/<form [^<]*>/g).length);
