localeTitle: 声明字符串变量
|
||
---
|
||
|
||
## Description
|
||
<section id='description'>
|
||
之前我们写过这样的代码：
|
||
<code>var myName = "your name";</code>
|
||
<code>"your name"</code>被称作<dfn>字符串变量</dfn>。字符串是用单引号或双引号包裹起来的一连串的零个或多个字符。
|
||
</section>
|
||
|
||
## Instructions
|
||
<section id='instructions'>
|
||
创建两个新的<code>字符串变量</code>：<code>myFirstName</code>和<code>myLastName</code>，并用你的姓和名分别为它们赋值。
|
||
</section>
|
||
|
||
## Tests
|
||
<section id='tests'>
|
||
|
||
```yml
|
||
tests:
|
||
- text: <code>myFirstName</code>应该是一个字符串,并且至少包含一个字符。
|
||
testString: assert((function(){if(typeof myFirstName !== "undefined" && typeof myFirstName === "string" && myFirstName.length > 0){return true;}else{return false;}})());
|
||
- text: <code>myLastName</code>应该是一个字符串,并且至少包含一个字符。
|
||
testString: assert((function(){if(typeof myLastName !== "undefined" && typeof myLastName === "string" && myLastName.length > 0){return true;}else{return false;}})());
|
||
|
||
```
|
||
|
||
</section>
|
||
|
||

<div id='js-teardown'>
|

```js
|
||
if(typeof myFirstName !== "undefined" && typeof myLastName !== "undefined"){(function(){return myFirstName + ', ' + myLastName;})();}
|
||
```
|

</div>
