Regex url is not recognized

Question

I have a regex in the server side that checks if the url is valid:

http(s)?://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?

This check is enough for me.

I want to make the same test in the client side.

So I created this jsfiddle:

http://jsfiddle.net/alonshmiel/LZf7H/1830/

I can't make the regex to be recognized:

var regex = /http(s)?://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?/i;

Any help appreciated!

You need to escape forward slashes / as it will be considered as premature end of regular expression pattern for javascript.

var regex = /http(s)?:\/\/([\w-]+\.)+[\w-]+(\/[\w- .\/?%&=]*)?/i;

Examples:

regex.test("http://test.com")
=> true

regex.test("http://www.test.com")
=> true

regex.test("http://abc.test.com")
=> true

the '?' in the sixth character doesnt say that http and https are not important? I dont understand why I got false for: www.google.com

You need to escape all the forward slashes.

> var regex = /http(s)?:\/\/([\w-]+\.)+[\w-]+(\/[\w- .\/?%&=]*)?/i;
> regex.test("http://myweb.com/api/v1/customer")
true
