I was looking for some email validation scripts and came across this: ------------------------------- var emailfilter=/^\w+[\+\.\w-]*@([\w-]+\.)*\w+[\w-]*\.([a-z]{2,4}|\d+)$/i function checkmail(e){ var returnval=emailfilter.test(e); return returnval; } ------------------------------- It works but I've never seen anything like that first line before. What is it called so I can learn more about it?
