Javascript regex doesn't match

I have been stucked with this problem for hours. I have a regex pattern and a matching string. Regarding to regex101.com, it is sure a matching string, but in my script, regarding to JSFiddle, it doesn't match.

RegExp: /\[img=?.*?http:\/\/lorempixel\.com\/640\/480.*?\/img\]/

String to match: [img=http://lorempixel.com/640/480]description[/img]

Script: JSFiddle

Can anyone find the problem here?

You can't concatenate a regex using a regex literal, and you need a regex for the .match method.

var regex = new RegExp("\\[img=?.*?" + regexSafeUrl + ".*?\/img\\]");

EDIT: James Montague is correct that .match will implicitly use a RegExp. You don't need the / in the string that gets converted to RegExp though or these will be considered literal slashes. Your real problem was doing this as well as not properly escaping in the string.
