Regular Expression is not working in JavaScript

Question

I have a problem with a regular expression, I tested that in some websites and it is working but when I use that regular expression in the project it is not matching with the correct result. the regular expression is the following

^(http|https)\://(www\.)[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(:[a-zA-Z0-9]*)?/?([a-zA-Z0-9\-\._\?\,\'/\\\+&amp;%\$#\=~])*$

I need that kind of regular expression because I need validate something like that:

http://www.test.com
https://www.test.com/login

the code that I am using is the following

var pattern = new RegExp(URL_REGEXP);
if (pattern.test($('input.editValueText').val()))

You forget to add + after the last character class. Your regex would be,

^(http|https):\/\/(www\.)[a-zA-Z0-9-.]+\.[a-zA-Z]{2,3}(:[a-zA-Z0-9])?\/?([a-zA-Z0-9-._\?\,\'\/\+&%\$#\=~]+)*$
