它应该验证这些类型的网址

解决方案

谷歌是你的朋友：好好经常拜访他。他可以比在这里发布问题更快地回答问题......

将来，请尝试自己做至少基础研究，不要浪费你的时间或我们的时间。

Bad想法。域名如wwww.mySite.tld（是的，4'w'）可以有效。为了确保它是这样，获得一些Web托管，获得自己的一些域名，并创建一个子域wwww。它会起作用，我保证。



（tld我的意思是顶级域名，例如com，org， net，edu等）



同时，像http：//www.mySite.tld这样的好网址可以是无效。因此，即使您可以轻松执行此验证，也不会提出此类问题，这种验证将毫无用处。

解决方案

Try this site. Hope it helps you.

Google is your friend: Be nice and visit him often. He can answer questions a lot more quickly than posting them here...

A very quick search using your subject as the search term gave over 1.75 million hits: Google[^]

In future, please try to do at least basic research yourself, and not waste your time or ours.

Bad idea. Domain name like "wwww.mySite.tld" (yes, with 4 'w') can be valid. To make sure it's so, get some Web hosting, obtain some domain name of your own and create a sub-domain "wwww". It will work, I'll guarantee it.

(By "tld" I mean "top-level domain", such as "com", "org", "net", "edu", etc.)

At the same time, "good" URL like "http://www.mySite.tld" can be invalid. So, this validation would be pretty much useless, even though you could easily perform it, without asking such questions.
