JavaScript_Regex小試牛刀-字串的替換

<script type="text/javascript">

var str = "Every man in the world! Every woman on earth!";

var patt = /man/g;    //全域搜尋man字串；

var result = str.replace(patt, "person");    //用person代替man字串；

document.write(result + "<br />");    //輸出：Every person in the world! Every woperson on earth!

patt = /(wo)?man/g;//新的Regex，有零個或一個wo字串；

patt.compile(patt);//重新編譯；

result = str.replace(patt, "person");

document.write(result);    //輸出：Every person in the world! Every person on earth!
