RegExp.$nThe n argument is a number between 1 and 9.
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); }
