Is there any regex which will validate both an absolute URL and relateve URl for Javascript.
I do have following Regex which works fairly well for absolute URL except the part where it is making the HTTP part mandatory. I want it optional.
Here is Regex:
/(http|ftp|https):\/\/[\w-]+(\.[\w-]+)+([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])?/;
thanks
quick answer, modified Arun's answer to accept '/page', '/page/subpage', 'page/subpage'
/(\/?[\w-]+)(\/[\w-]+)*\/?|(((http|ftp|https):\/\/)?[\w-]+(\.[\w-]+)+([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])?)/gi
but in actually, validate the url with RegExp is never esay. lots of edge case, like './page', '../page' etc.
analyse your requirement carefully, write down the major test cases, write a RegExp pass them all. and be careful with performance.
Try
/((http|ftp|https):\/\/)?[\w-]+(\.[\w-]+)+([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])?/;
It makes the (http|ftp|https):\/\/ (http://) portion optional
This one accepts things like:
http://example.com
https://example.com.com
/mypage
/my/page/
But not things like
httpa://example.com
my/page/
www
The regexp is:
/(^(https?:\/\/|\/)(?:www\.|(?!www))?[^\s])/
