lastParen Property ($+) (Windows Scripting - JScript)
Returns the last parenthesized submatch from any regular expression search, if any. Read-only.
Syntax
RegExp.lastParen
Remarks
The object associated with this property is always the global RegExp object.
The initial value of the lastParen property is an empty string. The value of the lastParen property changes whenever a successful match is made.
The following example illustrates the use of the lastParen property:
// Create the regular expression pattern.
var re = new RegExp("d(b+)(d)","ig");
var str = "cdbBdbsbdbdz";
// Perform the search.
var arr = re.exec(str);
// Print the output.
var s = ""
s += "$1: " + RegExp.$1 + "<br />";
s += "$2: " + RegExp.$2 + "<br />";
s += "$3: " + RegExp.$3 + "<br />";
s += "input: " + RegExp.input + "<br />";
s += "lastMatch: " + RegExp.lastMatch + "<br />";
s += "leftContext: " + RegExp.leftContext + "<br />";
s += "rightContext: " + RegExp.rightContext + "<br />";
s += "lastParen: " + RegExp.lastParen + "<br />";
document.write(s);
