Email pattern is like HYPERLINK "mailto:[email protected]" [email protected] you have to check the pattern of combination of these two. Sometimes space is also included in it. In pattern /^[a-zA-Z0-9._-][email protected][a-zA-Z0-9.-]+.[a-zA-Z]{2,4}$/ /../(forward slashes) is used to quote your regular expression. ^ shows beginning of string. [..] matches any letter enclosed with in. + shows that preceding character come 1 or more times. . Shows that \ will treat . as a literal. {2,4} shows the range that content having length between 2 to 4. $ is used for ending the string. test() method takes one argument and check that to the pattern.
