Thanks, though it doesn't quite work for what I want...

var myString = "the road to blah is long"
var myMatch = myString.replace(/blah/g, '');
alert(myMatch);
myString = "the road to there is long"
var myMatch = myString.replace(/blah/g, '');
alert(myMatch);
// which is a match?

...but you got me thinking down a new line.  In Perl you can set a var =
!regexp to flip the match.  So, I can iterate an array of matches and in
the loop look for :

// 'myArray' holds the target strings
// myRe holds the regexp
for (1=0;i<myArray.length;i=i+1) {
 if (!re.test(myArray[i]) { //
   //do stuff

or for a fixed string just...

// 'myArray' holds the target strings
for (1=0;i<myArray.length;i=i+1) {
 if (myArray[i] !== 'blah') { //
   //do stuff

My mistake was to try and construct a 'negative' test rather than look
for the failure of a positive one.

Thanks for the nudge!
