## Description
|
||
<section id="description">到目前为止，您只是检查字符串中是否存在模式。您还可以使用<code>.match()</code>方法提取您找到的实际匹配项。要使用<code>.match()</code>方法，请将该方法应用于字符串并传入括号内的正则表达式。这是一个例子： <blockquote> “你好，世界！”。匹配（/ Hello /）; <br> //返回[“Hello”] <br>让ourStr =“正则表达式”; <br>让ourRegex = / expressions /; <br> ourStr.match（ourRegex）; <br> //返回[“表达式”] </blockquote></section>
