Question

I have ref=Apple
and my current regex is

    var regex = /ref=(.+)/;
    var ref = regex.exec(window.location.href);
    alert(ref[0]);

but that includes the ref=

now, I also want to stop capturing characters if a & is at the end of the ref param. cause ref may not always be the last param in the url.

Answer 1

Use ref[1] instead.

This accesses what is captured by group 1 in your pattern.

Note that there’s almost certainly a better way to do key/value parsing in Javascript than regex.
