I'm still in the process of learning some decent regex but I would have thought this would work.

This works:

str.replace(/   /g,).replace(/(rn|n|r)/gm,);

But a shorter version of this, does not. Where did I go wrong?

str.replace((/  /g)|(/(rn|n|r)/gm),);

The regexpr delimiter is /, so you have the or | out of the expression. If you want to join them try with

str.replace((/  |rn|n|r/gm),);

By the way, the tab character is t in a regexp, so if you want to remove all tabs and new lines you can use str.replace(/[tnr]/gm,''); Said this, if with tab you mean any identation including 4 white spaces, then use str.replace(/ {4}|[tnr]/gm,'');
