Question

I am doing email regular expression validation for the email and I am stuck on one point using
following expression if user enter something like abc.abc then this expression works fine but when user enters [e-mail] then it doesn’t work

var myreg = new RegExp(/([a-z0-9.]+)@([a-z0-9]+)\.([a-z0-9]+)/i);
var patter =  myreg.test(document.getElementById("email").value)
alert(patter)
if(patter == false){
  errorMsg.push("email Formate Error Ex:[e-mail]");
}

I want that user must enter his email in this formate like [e-mail]/.ca/.org

var pattern = /^[a-z0-9]+\.[a-z0-9]+@[a-z0-9]+\.[a-z]+$/i;

pattern.test('[e-mail]');
// returns true;

pattern.test('[e-mail]');
// returns false;

pattern.test("abc.abc");
// returns false;
