Question

I want to validate a javascript string using regexp for URL.

I don’t wan’t to force http:// in the beginning.

What is the correct regexp, since I have the next one to include http:

var pattern = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/;

Answer 1

If you want to use the regex you already have, but make ftp, http and https optional. See following:

var pattern = /((ftp|http|https):\/\/)?(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/;
