Javascript regex backrefering

In Perl, this will successfully backreference TeXt.


  my $str = "this is TeXt";;

  if ( str =~ /(TeXt)/g ) ) {
    $str = $1;
  }

However, if I try something similar in Javascript:



  var str = "this is TeXt";;

  if ( str.match(/(TeXt)/g) ) {
    str = $1;
  }

This will not backreference TeXt

Any idea how I can access the captured group within the If block in Javascript?

The way Perl puts stuff in $1 and such is by having global variables(!) that get assigned to by the regexp parser. Javascript doesn't do this thank god. Your code should instead look something like this:

var matches = str.match(/(TeXt/g);
if (matches) {
    // do something with matches
}

You should look up the documentation for this on Mozilla's developer site (https://developer.mozilla.org/en/JavaScript).
