'How to validate the Display Name and Email Address together in a string using JavaScript or jQuery?
How to validate a Display Name and Email Address in the following format?
"John Doe" [email protected]
After doing the necessary research, the closest SO question I can relate my requirements to is: Extract email and name with regex
However, I couldn't find something solid, online. I am posting this question here in case someone has already developed a solution that they can share with everyone.
Wishful thinking is that if it can behave like MailAddress Class from System.Net.Mail namespace. https://docs.microsoft.com/en-us/dotnet/api/system.net.mail.mailaddress
function ValidateEmailAndDisplayName(emailAddressWithDisplayName) {
// A solid logic that addresses following test cases.
}
Quouted Display Name: ","
emailAddressWithDisplayName = "John Doe" <[email protected]> //=> True
Display Name without double qoutes:
emailAddressWithDisplayName = John Doe <[email protected]> //=> True
Comma in Quouted Display Name: ","
emailAddressWithDisplayName = "Doe, John" <[email protected]> //=> True
Comma in Display Name without double qoutes: ,
emailAddressWithDisplayName = Doe, John <[email protected]> //=> True
Backslash before adding double qoute: \
emailAddressWithDisplayName = "John \"Middle Name\" Doe" <[email protected]> //=> True
Missing backslash before adding double qoute: \
ValidateEmailAndDisplayName('"John "Middle Name" Doe" <[email protected]>'); //=> False
Missing closing angular bracket: >
emailAddressWithDisplayName = "John Doe" <[email protected] //=> Flase
TIA
