## Description
|
|||
|
|
<section id="description">到目前为止，您已创建了一组要匹配的字符，但您也可以创建一组您不想匹配的字符。这些类型的字符集称为<code>negated character sets</code> 。要创建<code>negated character set</code> ，请在<code>caret</code>括号后面和不想匹配的字符前放置一个<code>caret</code> （ <code>^</code> ）。例如， <code>/[^aeiou]/gi</code>匹配所有不是元音的字符。请注意字符之类的<code>.</code> ， <code>!</code> ， <code>[</code> ， <code>@</code> ， <code>/</code>和空格匹配 - 否定元音字符集仅排除元音字符。 </section>
