rightContext Property ($') (RegExp) (JavaScript)

Returns the characters from the position following the last match to the end of the searched string. Read-only.

RegExp.rightContext

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

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

The following example illustrates the use of the rightContext 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);
