I need a small parser (jquery) that knows if an input is URL:PORT format

Question

You have a user input string from a textbox for example var strInput = $("#txtBox").val();

strInput has some string now. I need to now if it is of this format: IP:PORT

Basically a user can input something like this: http://192.168.300.22:20000

1) Frist part (protocol): http:// always needs to be replaced by: https:// 2) Second part (everything until the ":" sign): 192.168.200.22 (or www.google.com) 3) Third part (port): everyhing after ":" (example: 9999, 100000)

I step): TAKE THE INPUT var strInput = $("#txtBox").val();

II) step): PARSE THE INPUT

III) results):

var strProtocol = "https//"; var strIP = parsedIP; var strPORT = parsedPORT;

So i need 2 know how to get the values (parsedIP and parsedPORT).

Answer 1

You can use regex for this. Pattern:

(?<protocol>\w+)://(?<ip>[\d\.]+)(:(?<port>\d+)|)
