## Description
|
|||
|
|
<section id="description">到目前为止，您只能提取或搜索一次模式。 <blockquote>让testStr =“重复，重复，重复”; <br>让ourRegex = /重复/; <br> testStr.match（ourRegex）; <br> //返回[“重复”] </blockquote>要多次搜索或提取模式，可以使用<code>g</code>标志。 <blockquote> let repeatRegex = / Repeat / g; <br> testStr.match（repeatRegex）; <br> //返回[“重复”，“重复”，“重复”] </blockquote></section>

|
|
- text: 你的正则表达式<code>starRegex</code>应该使用不区分大小写的标志<code>i</code>
