A regular expression can easily check whether a user entered something that looks like a valid email address.
Regular expressions are patterns used to match character combinations in strings.
//reported to validate incorrectly: [email protected] as true /[A-Z0-9._% -] @[A-Z0-9-] .
.[A-Z]/igm //reported to validate incorrectly: [email protected]@ as true /[A-Z0-9._% -] @[A-Z0-9.-] .[A-Z]/igm //current version /^(([^Sam Deering has 15 years of programming and website development experience.
It is a very simple function which uses a regular expression pattern match to test if a email is of a correct format. This takes in a parameter of the email address and then runs a pattern match against the regular expression.
If it doesn't find any matches then it will fail the validation and the function will return false, if the match returns true then the email will be of a correct format and the function will return true.
