Phone Number Field Validation

[Anonymous]

Hi,

Does anyone know how to custom add a "+" in front of the phone field type?

For example, if someone enters "123-456-7891" - is there a way to populate it as "+1-123-456-7891"? 

Thanks!

A javascript would be needed. I'm sure github or a developer can help you do this.

    MktoForms2.loadForm( "//app-zz01.marketo.com", "AAA-BBB-CCC", 999, function(form){
      form.onSubmit(function(form){
        var enteredPhone = form.getValues().Phone;
        if ( !/^\+/.test(enteredPhone) ) form.setValues({
          Phone : '+'+enteredPhone
        })
      })
  });
