I decided to use the onfocus event in an input field to have the Google picker displayed. I got that working, but I experienced an interesting situation with the Google picker continually being re-activated from the "onfocus" event of an input field. As soon as the picker closed, and the picked value was put into the input field the picker was re-displayed. I couldn't get the picker to not redisplay after the Select button in the picker was clicked. So, I needed to change the event to ondblclick in the input tag to open the picker. I'm guessing that the picker must reactivate the focus on the element that previously had the focus before the picker was displayed. I'm just guessing. The ondblclick event is better anyway. If the user doesn't want the picker displayed, then they can click in the field without being bothered to close the picker.
