quick email validation

minivalidator.js

function validate(name, email) {
  var errors = [];
  var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
  
  if(name === '') {
    errors.push('You forgot to enter your name');
  }
  
  if(email === '' || !emailReg.test(email)) {
    errors.push('Your e-mail address is invalid');
  }
  
  if(errors.length) {
    throw errors.join('\n');
  }
}

$(function(){
  $('form').submit(function(event){
    var name = $(this).children('input[name="name"]').val();
    var email = $(this).children('input[name="email"]').val();
    
    try {
      validate(name,email);
      console.log('success');
    } catch (err) {
      alert(err);
      event.preventDefault();
      return false;
    }
  });
});

I have a rule: Store a jQuery object in a var if used more than once. There's no point in creating more jQuery overhead.

var $self =. $(this);
