javascript - Regex to detect urls with '?' character at the end

Question

I found many solutions, but none was useful for me.

Let's say, as an example, I want to find URLs that start with www. and end with a space or ?. In this case, I really mean it ends in a ?, not that it's necessarily a CGI-related URL.

I'm trying to use the regex

var r = /(^|[s?])(www..+?(?=([s]|?|($))))/g;

My sample use: http://jsfiddle.net/DKNat/2/

How can I use ? in a regex to prevent the end of the URL containing / before ??

I can't solve last prob with DOT at the end of url. Can any body help?

Answer 1

Try this in your fiddle:

var r = /(^|??)(www.[^?]+)/g;

I updated your fiddle here:

Update:

I see what you are trying to do now. Unfortunately, both your strings are essentially the same, apart from the /, so unless you want your regex to make the assumption that a ? anywhere after a slash denotes a CGI call, then there isn't much you can do. But you could try this:

var r = /(^|??)(www.[^?]+/[^/]+?[^?]+|www.[^?]+)/g;

Update 2: After determining the requirements, this is the final RegExp I added to fiddle 10:

var r = /(^|[?s])(www.[^? ]+/[^/ ]*?[^? ]+|www.[^? ]+)/g;
