## Description
|
||
<section id="description"> <code>parseInt()</code>函数解析字符串并返回一个整数。它需要一个基数的第二个参数，它指定字符串中数字的基数。基数可以是2到36之间的整数。函数调用如下： <code>parseInt(string, radix);</code>这是一个例子： <code>var a = parseInt("11", 2);</code>基数变量表示“11”在二进制系统或基数2中。此示例将字符串“11”转换为整数3。 </section>

||
## Tests
|
||
<section id='tests'>
|
||
|
||
```yml
|
||
tests:
|
||
- text: <code>convertToInteger</code>应该使用<code>parseInt()</code>函数
|
||
testString: assert(/parseInt/g.test(code));
|
||
- text: <code>convertToInteger("10011")</code>应该返回一个数字
|
||
testString: assert(typeof(convertToInteger("10011")) === "number");
|
||
- text: <code>convertToInteger("10011")</code>应该返回19
|
||
testString: assert(convertToInteger("10011") === 19);
|
||
- text: <code>convertToInteger("111001")</code>应该返回57
|
||
testString: assert(convertToInteger("111001") === 57);
|
||
- text: <code>convertToInteger("JamesBond")</code>应该返回NaN
|
||
testString: assert.isNaN(convertToInteger("JamesBond"));
