The RegExp.$` property represents the substring preceding the most recent pattern match.
This is the same as using the leftContext property.
<html> <body> <script language="JavaScript"> <!-- pat = /is*/g; var str = "This is a test."; myArray = pat.exec(str);
document.write("In the string: " + "<b>"); document.write("I know where the fish is tonight" + "</b><br><br>"); document.write("The RegExp.leftContext is: " + RegExp.leftContext); --> </script> </body> </html>
