# --description--
|
|
|
|
到目前为止，已经创建了一个想要匹配的字符集合，但也可以创建一个不想匹配的字符集合。这些类型的字符集称为`否定字符集`。
|
|
|
|
要创建`否定字符集`，需要在开始括号后面和不想匹配的字符前面放置`插入字符`（即`^`）。
|
|
|
|
例如，`/[^aeiou]/gi`匹配所有非元音字符。注意，字符`.`、`!`、`[`、`@`、`/`和空白字符等也会被匹配，该否定字符集仅排除元音字符。
|
|
|
|
# --instructions--
|
|
|
|
创建一个匹配所有非数字或元音字符的正则表达式。请记得在正则表达式中包含恰当的标志。
|
|
|
|
# --hints--
|
|
|
|
你的正则表达式`myRegex`应该匹配 9 项。
|
|
|
|
```js
|
|
assert(result.length == 9);
|
|
```
|
|
|
|
你的正则表达式`myRegex`应该使用全局标志。
|
|
|
|
```js
|
|
assert(myRegex.flags.match(/g/).length == 1);
|
|
```
|
|
|
|
你的正则表达式`myRegex`应该使用忽略大小写标志。
|
|
|
|
```js
|
|
assert(myRegex.flags.match(/i/).length == 1);
|
|
```

```js

let quoteSample = "3 blind mice.";

let myRegex = /[^0-9aeiou]/gi; // Change this line

let result = quoteSample.match(myRegex); // Change this line
