Returns the last matched characters from any regular expression search. Read-only.

RegExp.lastMatch

The object associated with this property is always the global RegExp object.

Remarks

The initial value of the lastMatch property is an empty string. The value of the lastMatch property changes whenever a successful match is made.

Example

The following example illustrates the use of the lastMatch property:

function matchDemo(){
   var s;                                //Declare variable.
   var re = new RegExp("d(b+)(d)","ig"); //Regular expression pattern.
   var str = "cdbBdbsbdbdz";             //String to be searched.
   var arr = re.exec(str);               //Perform the search.
   s = "$1 returns: " + RegExp.$1 + "\n";
   s += "$2 returns: " + RegExp.$2 + "\n";
   s += "$3 returns: " + RegExp.$3 + "\n";
   s += "input returns : " + RegExp.input + "\n";
   s += "lastMatch returns: " + RegExp.lastMatch + "\n";
   s += "leftContext returns: " + RegExp.leftContext + "\n";
   s += "rightContext returns: " + RegExp.rightContext + "\n"; 
   s += "lastParen returns: " + RegExp.lastParen + "\n";
   return(s);                            //Return results.
}
document.write(matchDemo());
