I need to tab into an autofill field but skip fields in between

I have a form with several text fields that use the same name in order to autofill, i need to be able to set the tab order to skip fields and go directly into those fields. I have tried using the following code, but it doesn't work I'm assuming because there is more than one field with the same name. Is there a way to do this? this.getField("FieldName").setFocus();
