I am trying to create some JavaScript validation to only allow the input of a top level domain of an email address. eg(@gmail.com)
I have used the snippet below to try and form validation around the input, however it still allows full email addresses to be input. eg (mark@gmail.com)
function isEmailDomain(emailDomainVar) {
var regEmail = new RegExp('@(([a-zA-Z0-9-])+.)+([a-zA-Z0-9]{2,4})+$/');
return regEmail.test(emailDomainVar);
}
Thanks in advance for any input on this issue!
There is a symbol for matching the beginning of the imput: ^
. Simply add it in the beginning of your regex:
function isEmailDomain(emailDomainVar){
var regEmail = /^@(([a-zA-Z0-9-])+.)+([a-zA-Z0-9]{2,4})+$/;
return regEmail.test(emailDomainVar);
}
