$1...$9 Properties (JScript 5.6)


RegExp.$n

RegExp: Always the global RegExp object.

n

Any integer from 1 through 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:

┬á	Copy Code
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); }

┬á

Copy Code

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);
}
