let regex;
/* 匹配特定的字符串 */
regex = /hello/; // 查找斜杠中的字符串(大小写敏感)……匹配 "hello", "hello123", "123hello123", "123hello",但不匹配 "hell0", "Hello"
regex = /hello/i; // 查找斜杠中的字符串(大小写不敏感)……匹配 "hello", "HelLo", "123HelLO"
regex = /hello/g; // 全局查找斜杠中的字符串……
/* 通配符 */
regex = /h.llo/; // "." 匹配除了换行外的任何一个字符……匹配 "hello", "hallo",但不匹配 "h\nllo"
regex = /h.*llo/; // "*" 匹配任何字符零次或多次,如 "hello", "heeeeeello", "hllo", "hwarwareallo"
