I need a simple JavaScript regular expression to match URLs in a string. This is what I have at the moment: /(https?:\/\/)?[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9]\.[^\s]{2,}/gi This works 99% of the time for any URL that contains 3 or more characters, for example all of these work: abc.com abcd.com but I can't get it to work for a URL with 2 characters: ab.com ow.ly I'm using the match...

How can I define a regex that groups a number into threes excluding decimals? Example 1123456789 -> ["1","123","456","789"] 1123456789.999 -> ["1","123","456","789"] I've tried this Regex: /\d{1,3}(?=(\d{3})*$)/g But it outputs the following: 1123456789 -> ["1","123","456","789"] 1123456789.999 -> ["999"] Edit: removed _ from the example strings.
