## 将单个角色与多种可能性相匹配
|
|||
|
|
|
|||
|
|
### 提取
|
|||
|
|
|
|||
|
|
使用match（）方法，您可以提取与正则表达式匹配的字符串部分。在此挑战中，您将从提供的字符串中提取元音“a，e，i，o，u”。
|
|||
|
|
|
|||
|
|
### 提示1：
|
|||
|
|
|
|||
|
|
您是否尝试使用test（）方法？请记住，此方法仅返回True或False - 我们需要从字符串中提取元音。
|
|||
|
|
|
|||
|
|
### 提示2：
|
|||
|
|
|
|||
|
|
您是否尝试过不使用逗号的“\[\]”字符大小写匹配？即\[abcd\] vs \[a，b，c，d\]
|
|||
|
|
|
|||
|
|

## 解
|
|||
|
|
|
|||
|
|
```javascript
|
|||
|
|
let quoteSample = "Beware of bugs in the above code; I have only proved it correct, not tried it.";
|
|||
|
|
let vowelRegex = /[aeiou]/ig; // Change this line
|
|||
|
|
let result = quoteSample.match(vowelRegex); // Change this line
|
|||
|
|
|
|||
|
|
```
