## Description
|
|||
|
|
<section id="description">使用连字符（ <code>-</code> ）匹配一系列字符不仅限于字母。它也适用于匹配一系列数字。例如， <code>/[0-5]/</code>匹配<code>0</code>到<code>5</code>之间的任何数字，包括<code>0</code>和<code>5</code> 。此外，可以在单个字符集中组合一系列字母和数字。 <blockquote>让jennyStr =“Jenny8675309”; <br>让myRegex = / [a-z0-9] / ig; <br> //匹配jennyStr中的所有字母和数字<br> jennyStr.match（myRegex）; </blockquote></section>
