This is part of my jQuery script. I need to make the system validate emails for a specific domain.

And only allow emails from @schooldomain.com

Code:

email: function(value,element){return this.optional(element)||/^((([a-z]|d|[!#$%&'*+-/=?^_`{|}~]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])+(.([a-z]|d|[!#$%&'*+-/=?^_`{|}~]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])+)*)|((x22)((((x20|x09)*(x0dx0a))?(x20|x09)+)?(([x01-x08x0bx0cx0e-x1fx7f]|x21|[x23-x5b]|[x5d-x7e]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(\([x01-x09x0bx0cx0d-x7f]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))))*(((x20|x09)*(x0dx0a))?(x20|x09)+)?(x22)))@((([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])([a-z]|d|-|.|_|~|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])*([a-z]|d|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))).)+(([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])|(([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])([a-z]|d|-|.|_|~|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF])*([a-z]|[u00A0-uD7FFuF900-uFDCFuFDF0-uFFEF]))).?$/i.test(value);}

Firstly, as pointed out in the comments, validate the email using regex, and then check if the email is from the right domain.

function validateEmail(email) { 

    var re = /^(([^<>()[]\.,;:s@]+(.[^<>()[]\.,;:s@]+)*)|(.+))@(([[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}])|(([a-zA-Z-0-9]+.)+[a-zA-Z]{2,}))$/;

    if(re.test(email)){

        //Email valid. Procees to test if it's from the right domain (Second argument is to check that the string ENDS with this domain, and that it doesn't just contain it)

        if(email.indexOf(@thedomain.com, email.length - @thedomain.com.length) !== -1){

            //VALID

            console.log(VALID);

        }

    }

}
