Description
Returns the nine most-recently memorized portions found during pattern matching. Read-only.
Syntax
RegExp.$n

The n argument is a number between 1 and 9.

Remarks
The value of the $1...$9 properties is modified whenever a successful parenthesized match is made. Any number of parenthesized substrings may be specified in a regular expression pattern, but only the nine most recent can be stored.

The following example illustrates the use of the $1...$9 properties:

function matchDemo()
{
  var s;
  var re = new RegExp("d(b+)(d)","ig");
  var str = "cdbBdbsbdbdz";
  var arr = re.exec(str);
  s = "$1 contains: " + RegExp.$1 + "<BR>";
  s += "$2 contains: " + RegExp.$2 + "<BR>";
  s += "$3 contains: " + RegExp.$3;
  return(s);
}
