Question

I’m trying to set a cookie with a value that is made up of part of a referring url. The referring url looks something like:

http://webct.university.ac.uk/webct/urw/lc715920578061.tp721521425061/courseMenu.dowebct?

and I need to extract:

lc715920578061.tp721521425061

for reuse in another function.
Would this be regex? Could anyone help with the syntax?

Many thanks
Matthew

Answer 1

You can use replace with a regex and split like this:

var desired_part = document.referrer.replace(/^https?:\/\//gi, '').split('/')[3];
