Validate email field input

[gaidem]

I have a client script which will ensure input into an email field contains a valid email address:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   //If the page isn't loading
   if (!isLoading) {
      //If the new value isn't blank
      if(newValue != '') {
         //Type appropriate comment here, and begin script below
         var oldV = oldValue;
  validRegExp = /^[^@]+@[^@]+.[a-z]{2,}$/i;
  strEmail = g_form.getValue(email);

   // search email text for regular exp matches
    if (strEmail.search(validRegExp) == -1)
   {
      alert('A valid e-mail address is required.');
      g_form.setValue('email',oldV);
    }
   

      }
   }
}

Sadly portal and mobile do not work with a get control ID so you can't use a drop in script like that in the portal.. HOWEVER if you functionalize the script and remove the control ID it SHOULD work perfectly.

see section 2.1.5 and 2.1.6

I use this in the Service Portal, and it works perfectly.

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

          return;

    }

  var email = newValue + '';

  var regEx = new RegExp(/^(([^<>()\[\]\\.,;:\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,}))$/);

  g_form.hideFieldMsg('u_personal_email');

  if (!regEx.test(email)) {

  g_form.setValue('u_personal_email', '');

  g_form.showFieldMsg('u_personal_email', 'Please enter a valid email address', 'error');

  }

}

Did you try to just add an OOB email field to the form?

1. Make the email field visible (need admin and elevated roles):
   1. akash.sharma@trianz.com wrote in the thread Email Field type validation   that you will need to activate admin override   in the write acl for "sys_glide_object".
   2. Make email field visible from Field class table.
2. Add an field to your form.

Don't forget to de-activate admin override that you previously enabled.
