当我想使用正则表达式时，我遇到问题，我不知道使用'或'，'和'。喜欢在if语句中。

我有这样的网址

http://localhost:85/study/list

and i'm having the words(pattern to regexp) /,/list/top

我有单词（模式到regexp）/，/ list / top

when i try using this

当我尝试使用它

url ="http://localhost:85/study/list"; 
regexp = RegExp(.*/?/list?/top);
var matches =  url.match(regexp); 
alert(matches);

当我将url更改为http：// localhost：85 / top时/ top未检测到，但/ list是检测。哪里不对？

Man, you can test your expressions here RegexPal. It seems that the expression you using havo no effects.

伙计，你可以在这里测试你的表达RegexPal。看来你使用havo的表达没有任何影响。

This expression will match the last sub-directory of your url

此表达式将匹配您网址的最后一个子目录

(\w*)$

For example http://localhost:85/study/list will match list, http://localhost:85/top will match just top.

例如，http：// localhost：85 / study / list将匹配列表，http：// localhost：85 / top将匹配top。

Try it! =)

Put them in parenthesis, such as (/list)?.

把它们放在括号中，如（/ list）？

#3

list? matches lis or list. I think you want (list)?

清单？匹配lis或列表。我想你想要（列表）？
