Foil 76 Examples of Replace and test

From Overview of JavaScript I -- Basic Web Scripting Language CPS616 Technologies of the Information Age -- Spring Semester 99. by Geoffrey C. Fox (Tom Scavo)
<SCRIPT LANGUAGE="JavaScript1.2">
re = /(\w+)\s(\w+)/;
str = "John Smith";
newstr=str.replace(re, "$2, $1");
document.write(newstr)
</SCRIPT> // Prints out Smith, John
Suppose re is a RegExp object and str a string, then:
function testinput(re, str){
if (re.test(str))
midstring = " contains ";
else
midstring = " does not contain ";
document.write (str + midstring + re.source);
}
Prints out a summary of matching result
