Hi Guys,  Can anyone help me slim down this code I came across?  It checks for both business emails ( I know its not all free emails, just the usual ones its checking) and a valid email address.  The issue I see is that you need to insert all the email possibilities i.e. "yahoo.com",  "yahoo.co.uk". I think it would be better to make the validation check for contains "yahoo".  Love to know your thoughts or advice? <script> MktoForms2.whenReady(function(form) { form.onValidate(function(builtInValid) { if (!builtInValid) return; form.submittable(true); var vals = form.vals(); var invalidDomains = ["gmail.com", "gmail.co.uk", "gmail.om", "yahoo.co", "yahoo.com", "yahoo.co.uk", "hotmail.cm", "hotmail.co", "hotmail.com", "hotmail.co.uk", "outlook.cm", "outlook.co", "outlook.com", "outlook.co.uk", "aol.cm", "aol.co", "aol.om", "aol.com", "live.com", "live.co" ], emailExtendedValidationError = 'Please enter a Business email address.', emailExtendedValidationError1 = 'Email seems to be incorrect.', emailField = 'Email', emailFieldSelector = '#' + emailField; var invalidDomainRE = new RegExp('@(' + invalidDomains.join( '|') + ')$', 'i'); if (invalidDomainRE.test(form.vals()[emailField])) { form.showErrorMessage(emailExtendedValidationError, form.getFormElem().find(emailFieldSelector) ); form.submittable(false); } var emailRegExp = /^[^\s@]+@([^\s@.,]+\.)+[^\s@.,]{2,}$/; var validEmail = emailRegExp.test(vals.Email); if (!validEmail) { form.showErrorMessage(emailExtendedValidationError1, form.getFormElem().find(emailFieldSelector) ); form.submittable(false); } else { form.submittable(form.submittable() !== false); } }); form.onSubmit(function(form) { }); }); </script> ...
