Question

Hi I am using razor and trying to use regular expression to validate email address here the validation function

function validateEmail(txtEmail){
   var a = document.getElementById(txtEmail).value;
   var filter = /^[a-zA-Z0-9_.-]+@[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{0,4}$/;
    if(filter.test(a)){
        return true;
    }
    else{
        return false;
    }
}​

but since the regular expression has a @ sign razor thinks it part of it syntax and gives me an error.

Is there anyway to avoid to make sure razor disregards @ sign in JavaScript

Thanks.

Unicode may work like this

string filter = "/^[a-zA-Z0-9_.-]+\\u0440[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{0,4}$/";

Alternatively in razor @@ is a normal @ symbol, it should work in your javascript.

string filter = "/^[a-zA-Z0-9_.-]+@@[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{0,4}$/";
