## Description

|
<section id='description'>
|
|
让我们来给表单添加一个<code>submit</code>提交按钮，当点击提交按钮时，表单中的数据将会被发送到<code>action</code>属性指定的 URL 上。
|
|
例如：
|
|
<code><button type="submit">this button submits the form</button></code>
|
|
</section>
|
|
|
|
## Instructions
|
|
<section id='instructions'>
|
|
在表单的底部创建一个<code>button</code>按钮，按钮的<code>type</code>属性值为<code>submit</code>，文本为<code>提交</code>。
|
|
</section>

<section id='tests'>

```yml
|
|
tests:
|
|
- text: '表单内部应该有一个按钮。'
|
|
testString: assert($("form").children("button").length > 0);
|
|
- text: '按钮的<code>type</code>属性值应该为<code>submit</code>。'
|
|
testString: assert($("button").attr("type") === "submit");
|
|
- text: '提交按钮的文本应该为<code>提交</code>。'
|
|
testString: assert($("button").text().match(/^\s*submit\s*$/gi));
|
|
- text: '确保按钮有结束标记。'
|
|
testString: assert(code.match(/<\/button>/g) && code.match(/<button/g) && code.match(/<\/button>/g).length === code.match(/<button/g).length);
