match(regex2); console.log("匹配到的正则表达式1:", matches1); console.log("匹配到的正则表达式2:", matches2); 在这个例子中,我们创建了两个正则表达式对象(regex1和regex2),分别用于匹配“编程”和“快乐”。然后,我们使用match()方法在文本中检索这两个正则表达式的匹配项。最后,我们将匹配到的...
const regex = new RegExp(/^a...s$/); console.log(regex.test('alias')); // true Run Code In the above example, the string alias matches with the RegEx pattern /^a...s$/. Here, the test() method is used to check if the string matches the pattern. There are several other ...
