Returns the nine most-recently memorized portions found during pattern matching. Read-only.

RegExp.$n 

Arguments

RegExp

Always the global RegExp object.

n

Any integer from 1 through 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 + "\n";
   s += "$2 contains: " + RegExp.$2 + "\n";
   s += "$3 contains: " + RegExp.$3;
   return(s);
}
