JFTR, in this case one might want to use the more distinct

  str = str.replace(/'/g, "\\$&");

instead.  "$&" is equivalent to the matched substring, which comes in handy 
for more general replacements:

  /* from JSX:regex.js [1] */
  jsx.regexp.escape = function (s) {
    // ...

    return s.replace(/[\]\\^$*+?.(){}[]/g, "\\$&");
  };

RTFineM for more about replacement sequences [2].
